Why Lye In Soap? - Legend's Creek Farm
Why Is Lye Used in Making Soap? The short answer is that you simply can't make soap without lye. If a product doesn't begin with lye, it's a detergent, not a soap or a shampoo. That doesn't mean that some skin care products aren't made without lye, but they don't always do the same job or have the same benefits as soap.
