Dilutions Cheat Sheet for Dr. Bronner’s Castile Soap


Download PDF Document

Dilute! Dilute! OK!* But how much? Here is a quick reference. None of this is a hard and fast rule. If your stuff is really dirty or your water is really hard, then you may want to use more than the recommended amount. However, this should get you started. You’ll notice that for some applications, I recommend pre-diluting the soap – combining the soap with water in a container. For other applications, the soap is diluted by the water present in the situation. It’s a matter of personal preference. Keep in mind that if you predilute, you are also diluting the preservative (tocopherols – vitamin E), so the shelf life drops. Use within a couple weeks. And yes, there are 18 uses here. Dr. Bronner's Castile Liquid Soaps

* Long time Dr. Bronner’s users will remember this expression from the old labels.

Body Uses:

Face: 2-3 drops on wet hands, applied to wet face

Body: one small squirt on a wet washcloth, applied to a wet body

Hair: ½ Tbsp. in your hand, worked into wet hair, or dilute ½ Tbsp. in ½ a cup of water and work that into wet hair

Bath: Completely depends upon water amount, but roughly 2 Tbsp. soap in an average sized tub. (Doesn’t bubble, but still cleans)

Shaving: Face – 10 drops; Underarms – 3 drops; Legs – ½ tsp; Work to a lather in wet hands and then apply to area.

Teeth: 1 drop on a toothbrush. (Yes, it tastes like soap.)

Foot Bath: 1 ½ tsp. in a small tub of hot water.

Clearing Congestion: 1 Tbsp. in a bowl of steamy hot water. Breathe in mist with a towel draped over the head.

Household uses:

Dishes (handwashing): Pre-dilute 1:10 with water. Squirt on a scrub brush and scrub dishes.

Laundry: 1/3-1/2 c. of soap for a large load in a normal washer. Add ½ c. vinegar to the rinse cycle. Use half of these amounts for HE

Mopping: ½ c. of soap in 3 gallons of hot water

All-purpose cleaning: ¼ c. soap in a quart of water in a spray bottle. Add ¼ tsp. tea tree essential oil if desired.

Windows: 1 Tbsp. soap in a quart of water in a spray bottle. Follow up with pure club soda, or half vinegar/ half water.

Toilet: Predilute 1:4 with water in a squirt bottle. Add ¼ tsp. tea tree oil. Empty toilet, squirt bowl thoroughly, sprinkle baking soda on the brush, scrub bowl, let sit 10 minutes, turn water on, flush.

Other Uses:

Fruit and Veggie Rinse: 1 dash (approx.. ¼ tsp.) in a bowl of water. Dunk produce and swish. Then rinse in clear water.

Dog washing: Amount varies widely depending on size, hair type and length, and overall dirtiness. I wet my dog thoroughly, then start to work in castile soap up and down their body until I have a good lather. Really massage it in down to the skin. Your dog will thank you for it.

Plant spray for bugs: 1 Tbsp. in a quart of water. Add ½ tsp. cayenne pepper or cinnamon, if desired.

Ant spray (not on plants): ¼ c. tea tree soap in a quart of water. (This concentration will burn plants.)

I’ve tried to keep this short and sweet. If you have any questions, please ask away!

  1. I am a Dr bronner newbie and have a few questions. For laundry, do you add the soap to the dispenser or directly in the washing drum? What is the measurement for a cup size for laundry? Also, I have used the soap as a shower gel yesterday but it felt all dry until I washed it off. Was I using too much perhaps? Can you preprepare soap for showering and also for handwashing dishes? What would be the ratio? Many thanks!

    • Hi Andrea – Welcome! I’m glad you’re giving Dr. Bronner’s a try. My washer doesn’t have a soap dispenser section so I add it directly to the load. However, if I did have the dispenser, I would add it to that. A cup = 8 oz or 237 mL. (I need to get some metric conversions up there.)

      You can certainly predilute the soap for body and hand washing. You can fiddle with a ratio you like best, but perhaps start with a 1:4 ratio? I’m guessing here because the soap will be further diluted by the water already on your hands/body.

      Let me know if you have further questions!

  2. Hi Lisa,
    I’m a long time user & super fan of the Dr. Bronners line. Recently I made a few purchases of the: hemp cherry blossom & shikakai peppermint. Where can I purchase these on a regular basis?

    • Hi Ayar – Thanks for sticking with us for so long! We’ve made the shikakai peppermint (officially known as our Peppermint Organic Pump Soap and on sale this month, March ’16) since 2008-ish. It isn’t carried by nearly as many stores as our Castiles, though. Either call around to stores or order it online. Our webstore may not be the best price, so look around.

      The Cherry Blossom Castile is a whole ‘nother story! It’s brand new and we are still doing market tests with it to make sure it’s well-received before we stock up for a full launch. I think it’s only in Whole Foods stores this month (March ’16). It’s not even in our webstore. So you might want to pick up some more if you like it.

  3. Could you clarify please: You say in one posting that if washing hair to use apple cidre vinegar for a rinse. In another posting you say do not mix Castile with vinegar. Could you clarify please . This product is completely new to me so I am just beginning to look into it.
    Many thanks Josephine

    • Hi Josephine – I’m glad you asked because I, too, thought it might be unclear. The soap should be rinsed out of the hair thoroughly with water before using the apple cider vinegar or the Dr. Bronner’s Hair Rinse. If the soap and vinegar meet on the hair, it will be oily and messy. Use them as a one-two punch, one after the other.

    • Hi Sandra – I’d use my All Purpose Spray ratio of 1/4 c. of soap in a quart of water.

      All the best!

    • Does this solution need to be rinsed off laminate floors?

    • Hi Diane – Nope. It’s good to go with your mop.

  4. I keep a container of your baby formula castile soap in my bathrooms and kitchen. I love the soap and use it for my body, face and hands. I have problem with finding a good dispenser as it tends to clog up the opening. Any suggestions?

    • Hi Donna – We don’t recommend the Castile soaps in traditional pump dispensers for just that reason. Worse than a full clog is when it partially clogs and shoots soap up at the user. Foaming pumps work much better at a ratio of 1 part soap to 3 parts water.

    • I love using the foam pump method with Dr Bronner’s. It works well for hands and in the shower, I squirt it directly onto a sponge and use it on dishes too.

    • Hi Teresa – You’ll see other readers on here who have and with good results. It hasn’t gone well for me. For one, my hard water reacts with the castile soap and leaves a filminess on my glasses. Also, the soaps bubble more than conventional detergent and that can seep out of the seals of the dishwasher.

  5. Are all your soaps the same except for smell? If I want something with no smell to it do I use the baby?

    • Hi Terry – Yes, they all have the same soap base, with the addition of the different essential oils. However, the unscented Baby Mild not only has no essential oils, but the percentage of olive oil is also higher, creating an even milder soap for sensitive skin.

  6. Hi, what is the ph of Dr Bronners castille peppermint soap? I find it’s a bit drying on my body and I’m wondering if it’s because of the ph levels. Thanks!!

    • Hi Emily – The pH of the castile is 8.9. Peppermint oil, though, is naturally drying, which makes it a great option for oily skin or after work-outs and such. I’ve also heard testimonials from customers that this makes it a great aid to recover from poison ivy. However, it can be a bit intense otherwise. I don’t prefer it on a daily basis, but it is my go-to in the summer especially after days at the beach or working in the yard. Try one of the other fragrances, such as almond or citrus, which are not drying.

  7. Does ANYONE know of The (A) Average or (B) Best or (C) Most-Often Recommended or (D) The Ideal
    .for using It as One’s DAILY-BODY-SHOWER-SOLUTION??

    Thank You!!!

    • Hi Frank – Ha! You’re absolutely right. We get caught up in all these special uses that we neglect the basics. This is primarily a BODY soap. Personally, I don’t predilute my soap for the shower, for several reasons. First, that’s an extra step that I don’t feel like taking. Second, I feel that the water present in the shower, on my body, and on my wash cloth will dilute the soap already. Third, the prediluted soap always seems so much colder, and I’m a fan of a super hot shower. However, you are more than welcome to dilute it. I would recommend a 1:10 ratio to start with. You can tweak it to your personal preference.

  8. Hi! I had a few questions regarding your castile soap and hair care. I have been on a mission for an all natural and simple product for cleansing my hair. I started with the “no-poo” method of baking soda and vinegar, but the baking soda was too drying on my hair. Further research led me here! My questions are can anyone tell me the results they’ve experienced with using the pure castile liquid soap and the organic pump soaps, what’s the difference between the two, should I mix either with anything other than water (oil, coconut milk, etc.), and which you would recommend for primarily hair care? Thanks in advance!

    • Hi Saraya – I wrote a post comparing the two here: http://www.lisabronner.com/dr-bronners-pure-castile-vs-shikakai-soaps/. That might help get you started. I don’t combine my soap with anything, but lots of readers here do, especially with the coconut milk, so maybe one of them will weigh in here!

      Because I also have dry hair, I steer away from the peppermint, which is a drying oil. I most often use the Almond or Citrus, which are both very mild. That’s totally personal preference. I also opt for the Castile over the Pump soaps, but that’s more because the Almond and Citrus don’t come in the Pump Soaps. The Pump Soaps are more moisturizing, so that might be a good option for you.

  9. I’m looking for the kind of soap a person can wash with and not have to use water to rinse. Would this soap work like that? Or would pharmaceuticals like they use in hospitals for sponge bathing be better? I’m writing an eBook to help tourists coming to Nepal and many don’t expect to be without hot water while up on the trekking trail. But it’s cold, the windows don’t always close well and they might even be just wooden shutters. So this is going on my list if it would be useful to be used like this. Our NGO for post earthquake Nepal reconstruction: http://KayGarnay.org

    • Hi Amanda – Wow! What a great topic! Unfortunately, our soap will not work in waterless situations. I hope you find something that works!

  10. I use the castile soap soaps to deep clean makeup brushes about once a week and i was wonder if you had a ratio for daily spot cleaning without being too “soapy”

    • Hi Justin – Great use! For a daily cleaning of make-up brushes, I’d probably put one drop on the bristles, work it in, and then swish it in a cup of water. Or you could put a small squirt of soap in the cup of water and swish the brushes around. Perhaps squeeze the water out of the bristles with a clean towel and let them air dry.

    • Wondering what your ratio is for deep cleaning, Justin or Lisa?

    • Hi Michelle – For a more intense cleaning, you are welcome to increase the amount of soap to your liking. It’s not an issue of toxicity or anything – just not using more than is needed. You are welcome to double the amount of soap and see how it goes.

    • Hi Jetta – In a regular machine, for a small load, use 1/4 c. of castile to wash and then 1/4 c. of vinegar in the rinse compartment. For medium, go with 3/8 c. soap and 3/8 c. vinegar.

  11. I camp a lot where there is no fresh water. I have been making my own body wipes using a basic formula for baby wipes, which is 10 drops of Dr. Bronner’s baby safe liquid soap, per each cup of boiled water with some small amounts of pure moisturizing ingredients also added. They work great for quick, or even full body wipe downs. My question is do you think this will be safe to use on my little girls private parts and after potty, considering there is no way to rinse off with plain water?

    Thank you for any info you can give me or further suggestions.

    • Hi Betsy – Since I haven’t tried this, I can’t say a guaranteed for sure, but I think that probably this would be fine for a wipe without rinsing. I’ve read about a good number of baby wipe solutions that use about the same amount of soap in homemade wipes. This is a pretty similar situation.

      Can other readers weigh in on this one?

    • Bronners is fine not to rinse since it is natural and oil based. Dr. Bronner himself used to wash his hair every morning outside of the shower and just blot off with a dry towel. No rinsing. This was on his documentary.

    • I love that demonstration in the documentary! Keep in mind that he was using a very diluted solution. That works really well!

  12. I am a enthusiastic cheerleader for Dr b soap. I use it for nearly everything at home and for skin care. Recently I started making my own laundry detergent I grate the Dr Brummer’s bar of soap and add a couple of other ingredients. Because I am in the Garment industry, I know that certain soaps will dry out elastics. That is why for example if you used a product such as Woolite which is thought by many to be a great product for delicates its in fact disastrous on anything other than wool because the oils will eventually coat the elastic causing it to harden and crackle (I’m sure this has happened to everyone before when you try to put on an old pair of underwear and the elastic in the band crackles snap back). These oils are great for woolens because natural fibers such which NEED to be coated with oil. However those same oils will ruin elastics- which is in many undergarments and socks etc.

    So my question is what type of garment/fabric is the oil in Dr. Brommer effective on- wool or non woolens such as elastic.

    Thank you.

    • Hi Isadora – Wow. I thought I understood laundry, but you very clearly are miles ahead of me and I am very impressed. I really don’t know. Living in southern California, I really don’t have much in the way of wool. I’m not very knowledgeable there. From experience, I can say that I’ve not had any elastics harden or crackle since I’ve been using Dr. B’s for my laundry. That may be your answer right there.

      Perhaps another reader can weigh in here?

  13. Can I use the Eucalyptus Pure Castile soap to clean my wood cabinets? If so, what dilution should I use?

    • Hi Suzanne – Definitely! Use the All Purpose dilution of 1/4 c. of soap in a quart of water.

  14. I’m going to use your cheat sheet. Sounds so easy and I won’t have to mix up a lot of different cleaners. Sounds like one product can do it all. I am going to start with the unscented for bathing with, but what do you suggest to use for laundry and cleaning?

    • Hi Kathy – It’s very much a matter of personal preference and which scents make you happy. However, perhaps for cleaning, the Tea Tree castile has a slight advantage with its natural extra antibacterial power. But personally, unless I’ve got a super icky situation, I usually go with my mood. Often its the Citrus for me. Sometimes the lavender. Both for laundry and housecleaning.

  15. What is the best soap to use for laundry for a child with sensitive skin?

  16. Hi Lisa,

    I am a Dr Bronner newbie and would like to use it for laundry for baby clothes. I wonder if the formula is the same when its for baby clothes? Also, sorry for this stupid question but can you clarify what does HE stand for? TIA!

    • Hi Queenie – Great questions! Go for the unscented Baby Mild for baby clothes. It has no essential oils in it, to which babies might be sensitive. Yes, the formula would be the same. HE stands for High Efficiency – those are the “low water” washers, usually front loaders, that have come on the market in more recent years.

  17. Hi,
    I would like to use Bronner for floor cleaning, can I clean with solution without rinsing. Also what ratio should I use?

    • Hi Jeff – Yes, it’s great for floors and no need to rinse. I use 1/2 c. of soap in 3 gallons of hot water for my whole house.

  18. Hi! I just bought my first Dr. Bronner’s to make my own bath products. I bought the Baby Unscented because it seemed the most forgiving on skin and hair (and, honestly, there was a good deal on Amazon).

    I want to start making my own laundry detergent and other home cleaning products. Would the Baby formula work for those, or should I purchase a different soap? I’m not afraid of DIYing my own blends (I have baking soda, veggie glycerin, and tons of essential oils on hand).

    If I should be using a different soap for laundry, etc., could you please tell me which one and explain why not the baby? I’m still learning about Castile so any info would be greatly appreciated.

    Thank you!!!

    • Hi Rebecca – The unscented Baby Mild castile is a great base to use in all your DIY recipes. All our castile have the same base with different essential oils added. If you’re going to add your own essential oils anyways, the unscented is the best. Have fun!

  19. Hello Lisa. I have been using these soaps for over a year now and absolutely love the product! I have not seen any questions or comments about using the soap in a dish washer. Is it ok to use it in the dish washer, if so what would be the amount? Thanks.

    • Hi Jacqueline – I’m glad you like our soaps! I haven’t found them to work well in a dishwasher. I always end up with a film on my glasses. However, there are other comments on here from folks that have found combinations that work for them.

  20. I’ve read that the peppermint castile is good for eczema. Has anyone tried it. From the comments here it sounds drying. Would that make the eczema worse?

    • Hi Helen – From customer feedback, the Tea Tree pure castile seems to be the best option for eczema. Although I haven’t suffered from that, the Tea Tree did help immensely with my breakouts – totally cleared them up. I agree that the Peppermint can be drying. Give the Tea Tree a try instead.

  21. Hi, whilst looking for something to assist with itchy, dry skin and also interested in experimenting with essential oils, I recently purchased a bottle of Castile soap.
    Can you please advise the best way to make a tea tree hand wash? I have a 500ml bottle, should I dilute with water then add the tea tree and how many drops would be sufficient?
    Thank you for your help.

    • Hi Laura – For hand washing, you can use a couple drops straight out of the bottle, or you can dilute it into a foaming pump dispenser at a ratio of 1 part soap to 3 parts water. Do not dilute it into a regular soap pump as it will clog the pump.

  22. What would happen if you didn’t add the vinegar to the washing machine? I am so afraid that the castile soap is going to stain my clothing.

    • Hi Louise – The vinegar is only necessary if you have hard water. If you don’t have hard water, you don’t need to add it. There isn’t anything in the soap that would stain clothing – no colors or such. However, perhaps consider our Sal Suds, which is an excellent non-toxic detergent. Very mild, no colors, no fragrance. Even more effective and clean rinsing.

  23. I want to use the Baby Unscented Pure Castile Liquid Soap to wash my baby’s cloth because she has eczema. Is the soap good for eczema skin? Also, Do I have to use vinegar in the rinse cycle? If I use the vinegar, do I just add it to the fabric softener cup or I should add it manually in the rinse cycle? How much Castile Liquid Soap and vinegar I should use for half load of a HE washer? Is the soap also good to use when I hand wash cloth? Thanks!

    • Hi JZ – The Baby Mild unscented castile soap is great for babies and for soothing eczema. If you have hard water, it is a good idea to add vinegar to the rinse cycle. I do this just by adding it to the fabric softener holder in the washer. For a half load in an HE machine, I’d use just 2 Tbsp. of soap and the same of vinegar. It also works great to hand wash clothes. You can just squirt some into a sink full of water, or you can measure 1 Tbsp into the sink of cold water.

  24. I am a new user to Dr. Bronner castile soap, currently using the Lavender scented one. I love the fragrance. I am pregnant and am wondering if this is safe to use during pregnancy? Also, how much essential oil is present in the 32 fl oz bottle? Should I be diluting it to be safe to use during pregnancy?

    • Hi Suzie – Congratulations! I have looked into this questions myself through my three pregnancies, and yes, it is safe to use the Lavender soaps (and Tea Tree) through pregnancy. The concerns with both these oils is that at high concentrations they can permeate the skin and affect hormone balances. However, this is only a factor with products with high concentrations and that are left on the skin. Our soaps have the essential oils at a concentration of 2%, and they are washed off. Both of these reasons make them no problem at all for pregnancy. In a 32 oz. bottle, there would be around half an ounce of essential oils. If you are still concerned, check out our unscented Baby Mild soap, or perhaps our Almond or Citrus.

  25. I just want to say how much I love Dr. B’s castile soaps. I use them for everything.I especially love the lavender scented castile. What’s so awesome for me is that I find I do not need to use conditioner in my hair after washing it with lavender castile. My hair is left feeling so soft and easy to comb. I know this is probably unique to my hair type and I’m not necessarily recommending that anyone else forgo post conditioning but for me, this truly is a magical soap.

  26. I’d like to know if I can use the soap to make bubbles that the kids can blow? If so, how? Thanks!

    • Hi Eileen – Great question! I hope other readers weigh in here. I’ve been meaning to figure this out, but keep forgetting. The Castile Soap doesn’t make the best bubbles. Dr. Bronners Sal Suds (https://www.drbronner.com/DBMS/SALSUDSCLEANER/SSLI32.html) does a much better job, but I think you also need to add some glycerin for the best bubbles.

      Anyone have a good recipe?

  27. Do I have to pre-dilute the baby soap? Will it hurt my face if I use it undiluted directly on a wet buff puff?

    • Hi Michele – You do not need to predilute with the wet buff puff. Just a few drops will be great!

  28. Hello,

    I purchased Dr. Bronner’s Fair Trade & Organic Castile Liquid Soap – (Unscented, 16 oz) and want to use it on my natural African American hair. I have an 8 oz. bottle I want to put it in there along with the essential and carrier oil blends that work best for my natural hair. How do I properly dilute the soap to avoid over-drying or irritation to my scalp? Once I dilute it in water and leave it in a bottle, what is the shelf life? It is my first time using it so I am not too certain what to do. Thank you!

    • Hi Derlyne – Dr. Bronner’s Castile will work really well on your hair. For your hair type, try a dilution formula of 3 or 4 parts soap to 1 part water (any less and it may not suds up the way it should). Also, instead of adding a carrier oil, consider pretreating with an oil (like give your hair an olive oil or coconut oil pre-treatment), then wash it off with the soap, rather than mix the oil in with the soap. This pre-treatment is optional. You may find that you don’t need to use the Dr. Bronner’s Hair Rinse (https://www.drbronner.com/DBMS/ORGANICHAIRCARE/SD0701.html), but if your hair feels dry or tangly after washing than our Conditioning Rinse or diluted apple cider vinegar will smooth it out. Diluting does reduce the shelf life, so make smaller batches. It’ll still have a shelf life of at least a month or so.

  29. I have been using the Baby Mild soap in our foam dispensers and have found that it clogs very easily and leaves a residue in the sink which has resulted in clogging the sink drain. The soap has been great with cleaning hands so I don’t want to stop using it. Any suggestions with the dispensers and sink clogging?

    • I forgot my other question…can I make a multi purpose cleaner for kitchen countertops with the Baby Mild soap? Will it clean and get rid of raw meat bacteria, etc?

    • Hi Amanda – Try a more diluted solution. If you’re doing the 1:3 ratio, go to a 1:4 or more. That should take care of the pump clogging. However, I’m surprised to hear about the drain clogging. My husband helped me with a “How To” of clearing a sink drain. Check it out at the end of this one: http://www.lisabronner.com/deodorizing-the-sink-with-vinegar-and-baking-soda/. Let me know if you do find that the drain is clogged by build up on the walls of the pipe.

  30. Why do you need vinegar for hard water laundry use? Also, can you clean carpets with this?

    • Hard water is hard because it has a lot of dissolved minerals in it. Castile soap reacts with these minerals and can leave your clothes feeling stiff. Vinegar is a natural fabric softener and resolves this. Yes, you can clean carpets with it. Use the All Purpose spray for spot cleaning. If you’re using a carpet cleaner, though I find the Dr. Bronners Sal Suds to be more effective. One drop of Sal Suds in a carpet cleaner solution does the job.

  31. Hi Lisa,
    Does tea tree and cherry blossom suitable for 7 & 14 year old?

    • Hi Lili – Both are perfectly safe for children of all ages. I would guess that the sweetness of the Cherry Blossom might appeal more to children. It’s my 6 year old’s favorite. However, for teenagers who might be battling acne, the tea tree is a perfect option.

  32. I was wondering if you HAVE to rinse apple cider vinegar or anything else for that matter through the hair after the soap? Just that the smell it’s self makes me gag! Thankyou

    • Hi Kat – Nope, you don’t have to. Some hair types do perfectly fine with just the soap. However, if you find that your hair is tangly or rough, you might benefit from an acid rinse. The Dr. Bronner’s Hair Rinse is another alternative to the apple cider vinegar, and does not have the smell of vinegar.

  33. I’m curious whether I’m able to mix the soaps themselves for sort of custom scents eg Citrus-Almond or Lavender-Rose? While I love the scent of the eucalyptus soap I have found it causes me to rash if used over long periods of time, but have never encountered this problem with the other scents. So I was considering possibly an Almond-Eucalyptus mix to have a unique smell and hopefully mitigate some of the negative effects of the eucalyptus soap. Thanks!

    • Hi Randolph – Mixing the scents to create your own unique blend is a fantastic thing to do! Mix away!

  34. Hi Lisa,
    Thank you for this post! I am wondering if the Tea tree scented Castille soap has the same antibacterial properties as adding pure tea tree essential oil. If I use the tea tree soap, may I omit adding the essential oil and still benefit?

    • Hi Lauren – Tea Tree pure essential oil certainly has antibacterial properties of its own, so Yes, I think you’d get that extra punch just from using the Tea Tree Castile soap.

  35. What is a good dilution to use for hand soap in a pump next to sink?

    • Hi Donna – Only use a foaming pump dispenser for the castile soaps, and start with a ratio of 1 part soap to 3 parts water.

  36. I’m new at starting my own homemade non toxic natural cleaners, body washes, etc. I’m actually studying to become a certified aromatherapist(eventually registered) so incorporating essential oils to all my things I make. Since I’m new, I’m not sure of the quantity of ingredients to purchase. I don’t want to not get enough because then it’d be wasted (trial and error) and spending more money (I’m on a budget) but don’t want to get too much if it won’t last very long. So just wondering what you recommend be the amount to purchase. As far as right now goes. I’m wanting to incorporate castile soap for use of cleaning the house and make a dishsoap and to make a soap for my 4 year old and 1 year old. Eventually for myself and my husband. But I’ve started with cleaners since I’m still educating myself on the use of oils. I’d appreciate your feedback, thankyou! 🙂

    • Hi Chiane – Start with 1 quart of our pure castile soap. For all these uses, I think that would get you through a couple months.

  37. I was also wondering if I added pure vitamin e oil to a body wash mix that was diluted if that would help preserve it and last longer? I want to save as much money possible and I want my products to last and also want them to work.

    • Yes, that would work! Also consider making smaller batches that you’ll use up more quickly.

  38. Can you give me a conversion rate for your castile soap? Specificly , how much of your liquid would equal 1 bar.
    Thank you.

    • Hi Duane – Here you go: Bar soaps are 5% water; liquids are 61%. The chemistry is a little different for both, but considering that a bar soap is 5 oz, and thus 4.75 oz of non-water soap, you would need 12.18 ounces of liquid soap to equal the non-water content of a 5 oz bar.
