Baby Don't Lye
Is there lye in my soap? I receive quite a few inquiries about lye. The answer is no, but it is much more complicated than that. All soap is made with lye. So if someone is telling you that they have a soap that is not made with lye, well now, that's just different kind of lie.
In other words, soap is created when fats or oils are mixed with an alkali, such as lye. A chemical reaction called saponification occurs and soap is the resulting product. Lye is the catalyst in this chemical reaction and a necessary ingredient in the soap making process but soap that is correctly made, contains no lye in the finished product.
We can use a breakdown of the Dove beauty bar ingredients as an example. Why Dove? Mostly because everyone tells me their doctor told them to use Dove. We can't expect doctors to be knowledgeable about all subjects. I once told the doctor that my daughter was allergic to wheat and her reply was that I should give her white bread. Go figure?

This product is called a beauty bar, it is not considered a soap even though it has some saponified ingredients. It does not have enough saponified ingredients to qualify as a soap and its cleansing properties are not solely from saponified fats.
Here are the ingredients in our PURE soap. This is a very mild castile soap that has a similar feel to a soap with a moisturizing cream added. This product is true soap and we are not even required to list the ingredient on the packaging, but of course, we do!
