Here at Metaphor Organic, we’ve been using organic soap for so long it seems like a no-brainer. We rarely think about all the reasons we got into the soapmaking game or why we set out to make the best soap we could. That’s not to say that we never thought about it. We just made our decision long ago, and have been going with it ever since. However, if you haven’t thought a lot about what goes into your personal skin care products, the following article should give you a bit more information.
Introduction to the benefits of organic soap
What is the number one benefit of Organic soap? Organic soap is simply better for your skin. It contains natural ingredients such as plant-derived base oils, glycerin, and essential oils. By contrast, synthetic, mass-market soap is made of petroleum-based lathering agents, synthetic fragrances, harsh dyes, and dangerous preservatives. It’s not surprising, then, that a lot of our customers say that their skin feels better after using organic soap, and that it sometimes helps to improve skin conditions such as eczema and acne, rather than producing further irritation.
But not only is organic soap better for you, it’s also better for others. It’s better for the environment because producing its ingredients has less of an environmental impact, and because those ingredients break down easily and cause fewer problems after they go down the drain. It’s better for animals because its ingredients are already recognized as safe, so no animal testing is necessary. And finally, organic soap is better for the economy, because it is often made by small, local producers, so the dollars you spend on it stay in the community.
What do I mean by organic soap?
When I talk about organic soap, most of the time I’m talking about natural and organic soap. Natural soap is made out of fats or oils, water, lye, and often essential oils and natural dyes. Organic soap also has the added benefit of being made of ingredients that are produced with organic farming practices, that is, farming practices that don’t use pesticides or synthetic fertilizers. So organic soap is natural soap, but it is also one step better.
Organic soap is made of ingredients that are better for your skin
Organic soap is made from natural ingredients, and in most cases, those ingredients are also organically farmed. The majority of the soap bar is made of what are called base oils. We use some of the same base oils for soapmaking that you can use for cooking. So if it’s safe to eat, it’s probably also safe to put on your skin. In the case of our latest recipe, those oils are coconut, olive, and castor bean oil. (We used to use palm oil but are phasing it out because of the massive amount of environmental destruction that it takes to produce.)
Another ingredient in our soap is essential oil. Essential oils are the volatile or fragrant compounds in certain plants. Most essential oils are distilled from things you would eat such as citrus fruit or herbs. Two examples of essential oils we use are lemon essential oil and rosemary essential oil. Experts say you shouldn’t put pure essential oil on your skin because it is very concentrated and can cause irritation. However, essential oil diluted with another oil is just fine.
Most organic soap also contains glycerin. Glycerin is a natural product of the soapmaking reaction. A lot of mass-market soapmakers and some small-batch soapmakers take out the glycerin because it makes the soap bar last longer or because they can sell the glycerin to use in other cosmetic products. However, when glycerin is left in the soap bar, it acts as a humectant, or a substance that attracts moisture from the air into the skin. Two other natural humectants are aloe and honey.
What about lye?
Lye is a purified natural substance that does not meet the definition of “organic.” Lye does have it’s origins in wood ashes, so it is plant-based. But it doesn’t seem like something you’d want to put on your skin. So what gives? Well, one soapmaker explained there is a difference between “contains lye” and “made with lye.” Soap is made in a chemical reaction between lye and oil. So, if done properly, there is no lye left in the soap once the soapmaking reaction is complete. There are only sodium ions, fatty acids, glycerin, and a bit of water. (And essential oils and whatever else you put in the bar.) If you have any more questions about how this works, google knows the answer, or you can send and email to email@example.com, and we can grab a beer and chat about chemistry.
Soapmaking and cooking
A few years ago a friend bought a house, and her father came to visit to help her with a couple of carpentry projects before she moved in. We were all having dinner one night, and he said something that stuck with me. If you start with the best ingredients, and manage to combine them with a little bit of skill, you’ll probably end up with a pretty good dish. If you think about it, this makes a lot of sense. Imagine buying a salmon right off the boat, which you could when I was growing up on the Oregon Coast. Imagine taking the salmon home and cooking it over an open fire in the back yard. Pristine ingredients. And sure, it takes a little bit of skill to cook fish over a fire. Now imagine fish sticks that you buy in the freezer section of the grocery store. Imagine all the technical steps and machinery it takes to make fish sticks. Now which tastes better? In my experience, soapmaking works the same way.
What organic soaps do not contain
Now that we’ve talked about some of the good stuff in organic soap, I'm going to mention a few of the bad things found in mass-market commercial soap. Three ingredients I’m going to examine are surfactants, parabens, and artificial frangrances.
Surfactants are the chemicals responsible for the cleansing properties of a particular product. Surfactants are made of long molecules with two different ends. One end of the molecule sticks to water, while the other sticks to dirt and oil. Surfactants, as a category aren’t automatically bad for you. Soap is technically a surfactant. But you have to be careful about which surfactants you put on your body. One of the most common surfactants in personal cleansers and shampoos is sodium lauryl sulfate. Sodium lauryl sulfate, or SLS, is made from coconuts, but it is contaminated with toxic byproducts when it is manufactured. SLS has been linked to skin irritation, toxicity, endocrine disruption, and cancer. Another unsettling fact about SLS and many other synthetic substances is that your body doesn’t have the enzymes to break them down, so they may accumulate in your tissues over time.
Parabens are a specific type of preservative used in a wide range of cosmetics and pharmaceutical products. More specifically they prevent growth of mold and bacteria. Paraben is actually short for “parahydroxybenzoate.” The reason we should avoid parabens is because they act like estrogen in the body. Too much estrogen can lead to breast cancer and reproductive issues. One piece of good news is that there are a lot of newer safer preservatives available, so a company that is still using parabens is really just being lazy. When inspecting labels on cosmetic products you should look out for the three most common parabens: butylparaben, methylparaben and propylparaben. Or you can just opt for a simple, natural product such as organic soap!
Let me tell you a story about artificial fragrances. Back in the early days of Metaphor Organic, we used some of them. (Hangs head in shame.) We bought all our essential oils down the street at a little bulk herb shop, and the artificial fragrance oil was right next to the essential oils. We didn’t know any better! But the more research we did, the more we realized we should phase them out. For example, there was an artificial vanilla that we used in some of our scent blends. Then we tried to find natural vanilla, but it was very expensive and it didn’t smell very distinctly. So we wrote to the manufacturer of the artificial vanilla to try to find out what was in it, because maybe then we could justify putting it in the soap. But they wouldn’t tell us! Artificial fragrances recipes are protected as trade secrets. So maybe they are fine, but other sources report that the majority of artificial fragrances are derived from petroleum.
There is a long list of other synthetic ingredients that may be found in mass market cleansing bars, but listing them would make this article way too long. The best place to look for info on just about every additive to personal care products (and food) is the Environmental Working Group, or EWG. It’s their job to stay up to date on all the latest research on potentially harmful chemicals.
Why do companies use chemicals?
Ok, technically everything is made of chemicals, but you know what I mean. Why do large skin care companies use synthetic ingredients? For one, they’re cheaper than natural ingredients. For another, they’re easier to process and store. And finally, it’s easier to get them to produce exactly the desired result, such as super intense colors and scents. Remember that artificial vanilla we found at the herb store? It smelled like an hyper-natural BLAST of vanilla. Unfortunately, a lot of natural scents aren’t able to translate into soap. You can distill the essential oil out of a certain number of plants, mostly strong-smelling herbs, but I’ll bet that blueberry-ice-cream-scented soap is synthetic. Likewise, many flower scents are incredibly expensive to distill in their natural form, so, for example, if you want a jasmine bar of soap that costs less than $25, you have to use synthetic.
Soap that isn’t soap
As a final note on artificial soap, you might have noticed that a couple paragraphs ago I used the term “cleansing bars.” That’s because, legally, soap has to be made out of mostly oil, water, and lye. If it’s not, they have to call it something else, such as a detergent or “syndet” bar. That doesn’t mean that some companies don’t make actual soap and then put a bunch of other stuff in it. Dove soap is a great example. One ingredient is listed as “sodium tallowate,” which is just another way of saying tallow, or beef fat, that has reacted with the lye catalyst. Maybe not very delicious, but it is natural. But Dove also contains cocamidopropyl betaine, a synthetic surfactant. Likewise, Lush soap, even though we love its minimal packaging, contains SLS and parabens.
Organic soap is better for the environment
In the last part of this article, I’m going to talk about why organic soap is the best choice if you’re concerned not only about what sort of products you put on your skin, but also, the greater impacts of the production and disposal of those products.
