95/5 Soap contains 95% natural ingredients and 5% synthetic fragrance. There is no such thing as peach or blueberry essential oil. These and many other fragrances are only available as synthetics. If you have chemical sensitivities, we recommend that you try our 100% natural soap first. Buyer beware: if you see 'fragrance' as an ingredient on any product claiming to be all or 100% natural, it's not.
