Who Gave Soap a Bad Name?

Somewhere along the way in recent years, we’ve accepted the idea that soap isn’t good enough. The myth persists that only potent, synthetic antibacterial agents are legitimate cleansers and soap simply isn’t effective.

This idea stems partially from the pursuit of efficiency, the desire for cleanliness, and the promotion from advertisers. Although it is true that products such as these do clear away soap scum faster and kill germs “on contact”, if you look at the long term costs and effects, little time or anything else is saved. Rarely does a product do only one thing, such as kill germs. One very common ingredient, Triclosan, which is in everything from toothpaste to bathroom cleaners to hand wash to socks and cutting boards, has also demonstrated in recent studies the ability to alter hormones and create antibiotic-resistant superbugs. Quite a multitasking product. So, down the road when our bodies get sick or start to malfunction, will the few minutes we saved cleaning the bathroom really matter?

Bronner's soap is strong enough for most around the house cleaning

The idea that soap doesn’t clean well is also unfounded. Terms such as “antibacterial” actually have carefully regulated definitions. “Antibacterial” means that the product must kill 99.9% of germs. The term “disinfectant” means that the product must kill a mere 99% of germs. Dr. Bronner’s soap is part of the “disinfectant” category. It’s not a term we readily spout out regarding the soap because it sounds so unnatural and not something we want to put on our bodies, but for the purpose of this debate, I’ll use it. Just so you know. So if you’re still really paranoid about germs and suspicious of simple soap, grab hold of a bottle of Tea Tree Castile soap or even a bottle of pure tea tree oil (undiluted this can burn, so use care). Although the US government doesn’t yet recognize it as such, tea tree oil is a naturally occurring antibacterial agent.

In comparing the cost of conventional bathroom cleaners versus a homemade soap solution, both the upfront and long term calculations favor the soap solutions. The recipe I use at the end of this post costs roughly $1.10, compared to an estimate of $2.99 for a bottle of conventional spray cleaner. (These numbers and the recipe are from Karen Logan’s fabulous book, Clean House, Clean Planet. I highly recommend this book for ways to replace toxic conventional products.)

To continue with the evils of conventional cleaners, let’s assume that you wear gloves when using them, so they don’t come into contact with your skin during application. (I rarely remember to wear my gloves, if I even know where I put them. Usually I’m cleaning the bathroom while my kids are in the tub, so I can’t leave the room to find my gloves anyways.) But consider what about the little residue that may be left on the tub, that ends up in the bathwater which the kids inevitably drink as they blow bubbles? What about what might remain on the toilet seat, and be absorbed through the skin of their bottoms? What about the little bit that ends up on the counter, which the kids touch and then eat their sandwiches? What if this happens every day – several times a day – for their entire childhood? How much ends up in their little, developing bodies?

Here’s a great recipe for an all-purpose household cleaner that Karen Logan calls “Merlin’s Magic”:

  • Fill a 16 oz. spray bottle nearly to the top with water. Add 3 Tablespoons of your favorite Dr. Bronner’s castile soap and 20-30 drops of tea tree oil. Shake it well and spray it on bathroom or kitchen surfaces, floors, even dirty little hands if they’re nearby. Wipe off with a damp cloth.

  1. Good to know that the tea tree soap is a natural antibacterial. I was keeping 2 bottles of soap in the kitchen… Dr. B’s for most things and a bottle of harsh antibacterial for when I handled raw meats. Now I can just use the one (by chance is the TT type). Thank you for the info.

  2. Thanks Lisa for all your tips. I have enjoyed watching your videos. Tell me something do u ever wash your face with the soap? I wish there was a line of products for your face.
    Loved all your green ideas.

  3. Carmen – I only use the pure castile soap on my face. I have been through the wringer with facial products – trying everything from conventional stuff to the stuff only available through dermatologists. Then I returned to Dr. B’s pure castile Tea Tree. It cleared up my acne and reduced redness. For the first couple months, my face did feel a little tight, so I followed up with our Lavender Coconut lotion. That worked great, too. Now, I guess my skin has gotten used to the soap because I don’t need the moisturizer anymore. If you want to start with the gentlest and work your way up, try the unscented Baby Mild first.

  4. I’ve been reading on tea tree oil and there’s concern that it too contributes to superbugs. I ended up returning the tea tree Dr. Bronners for baby-mild.

    Low concentrations are a major concern but I think in general, too, just as using alcohol, triclosan, etc.. Over-de-germing is becoming a serious problem and hazard to our health and environment.

    I didn’t save the articles, but here is one: http://www.netdoctor.co.uk/interactive/news/theme_news_detail.php?id=18065009&tab_id=106

  5. btw, just used it on my hair, first time using the product. Wow the lather! My hair is puffed. Seems to have dried my face a bit. I want to use it for housecleaning. Hear it degreases and cleans a tub like nothing else. “Real” soap.

  6. @Jill – Thanks for bringing up this issue. It looks like the research is targeting using tea tree oil alone for disinfecting. However, in our soap, which disinfect on their own already, there’s not going to be this cleansing gap. The tea tree oil adds to the cleaning ability that’s already there. There is a 2% concentration of the essential oil in our soap. If you go greater than that, there are a few other risks. First, tea tree oil can burn at a high concentration. Never touch the oil straight. Also, other concerns have been raised about the oil’s affect on hormone levels, especially in boys and pregnant women. There is no concern over the Dr. Bronner’s levels because our concentration is low, and our product washes off, unlike the oil in a lotion which remains on the skin and is more fully absorbed.

    It’s good to keep learning more about the products we’re using. Thanks for bringing this up!


    • Please help I have MRSA and am looking for natural product to kill the bacteria on my skin. the article warns against any concentration lower than 4% tee tree oil. you say there is only 2% tee tree oil in Dr Bronner’s soap. so does that mean that the Dr Bronner’s soap does not kill MRSA and other bacteria?

  7. Is the soap safe for nursing and pregnancy? I know some essential oils are unsafe during pregnancy?

  8. Hi Tamara – Yes, it is safe during pregnancy. There is some concern with essential oils when they are applied to the skin in higher concentrations and in “leave-on” products such as massage oils or lotions. HOwever, in our soaps, there is a 2% concentration, and it is rinsed off, so very little of the essential oils remain on your skin.

    All the best,

  9. Hi! Is the almond one safe to use to make baby wipes? With 1 3/4 c water boiled and 3 tbsp soap?

  10. Dear Lisa, thankyou for a such lovely blog you have here… ^_^
    anw, it is save using dr.bronners pure baby liquid with eczema skin during pregnancy?
    or do you have any advice for my very dry skin (getting terribly more dry while pregnancy) ?
    thanks a bunch for your reply 🙂

    • Hi Felcia – Thanks! The soap is fantastic and perfectly safe for use during pregnancy. During pregnancy, I remember itching all over, and it was Dr. Bronner’s coconut oil that came to my rescue. I rubbed this on my belly and had my husband do my back.

      Best wishes with your little one!

  11. I know that a lot of these mixtures call for water to be added- but how do you keep the mixture from smelling like dirty mop. I noticed that after a few days the water in the bottle will smell like mold/mildew. Help!

    • Hi Margaret – That doesn’t sound good. Here are a couple thoughts – starting with the basics, make sure the bottle is really clean. If you’re making a fresh batch, rinse the bottle thoroughly of the previous batch. Adding the water dilutes the essential oils which are giving it its scent. You can add extra essential oils to boost it back up – perhaps 20 drops of sweet orange oil or lavender oil. Another thought is to make smaller batches, or to add more soap to the dilution.

      Your solution most likely is not turning rancid so quickly – that would only happen if the dilution were left several months. You can check this by seeing if the solution still cleans. My top guess is the dilution of the oils is lowering the scent too much. The essential oils are at a 2% concentration in the soap itself, so if you are cutting that by 16, you get a really diluted amount.

  12. So if a disinfectant kills 99% of the germs, I’m assuming that is what the straight soap does, as a disinfectant. When you mix it with water to make a cleaner for the bathroom or kitchen, does it lose its effectiveness, since it’s so diluted? I am curious to try a bottle sometime as I’m trying to move away from commercial cleaners, and my family doesn’t like the smell of vinegar, which I have also been using. 🙂

    • Oh, and if I do try it, I’ll use the unscented, and I won’t add tea tree. We have cats, and they often jump up on the counter on their way to the window. I’ve read tea tree is toxic to cats, and don’t want to take the chance of them absorbing it through their paws. 🙂

    • Hi Emily – Soap works by essentially grabbing germs/grime/dirt on one side and grabbing water on the other. The soap actually works best at grabbing those germs when it is properly diluted. It needs the water. My dilution recommendations can certainly be tweaked to the occasion – if you’re facing a super grimy situation, you’ll need a higher soap concentration in order to have enough soap molecules to grab on to all those grime molecules. If you have a light cleaning situation – let’s say a window – you might want to do a more diluted concentration.

  13. I’ve been using Dr. Bronner’s soap for about a year now and love it. Body wash, baby wipes, etc. I just picked up a bottle of Peppermint soap but I can’t find any info on this, whether or not I can use it while pregnant. I know peppermint oil is not safe in pregnancy but is this diluted enough to be safe?

    • Hi Cathy – Yes, the Peppermint Castile Soap is safe to use during pregnancy. The concentration of the peppermint essential oil is 2%. The combination of that dilution along with the fact that soap is a “wash off” product and doesn’t have a tremendous amount of time to penetrate the skin, makes it perfectly safe for pregnancy. This goes for all of our soaps. I looked into it myself when I was expecting.

  14. I am using the peppermint Castile soap and this is my first time ever using it. I added a small amount to a 160z. Bottle of hot water and wiped my table and countertops down. I had seen something about rinsing it off of countertops….. I’m a tad confused about that. I’m also wanting to use it as hand and body soap and am unclear of the dilution scale of that.

    • Hi Chelsey – Welcome to Dr. Bronner’s! If you wipe down with a damp cloth (I recommend microfiber), you don’t need to rinse it. The cloth will pick up the soap and the dirt. For hand and body, I don’t predilute since the water that’s already on my skin dilutes it. For hands, a couple drops will do. For the body, I use a wet washcloth and a good squirt (probably works out to about 1 tsp. of soap) for my whole body.
