At Feto Soap, we create soaps from scratch using the Hot Process and Cold Process Methods. Hot Process soaps are similar to Cold Process soaps in that they are created from scratch using a basic combination of water, lye and oils. In a finished soap, the oils are saponified (converted into soap) and no longer contain any lye. Our soaps are scented with fragrance and essential oils. Fragrance oils are synthetically created and essential oils are plant-derived (natural). If you have any questions about any of the ingredients we use to create our soap, we would be happy to answer them for you.
