Essential Oils

Essential oils have superior scent retention and are very powerful. Many are beneficial, but some can be extremely harmful. They are however, preferred over fragrance oils in soapmaking because they are less likely to affect saponification and seize soap. Problems may occur in soapmaking when using citrus essential oils, so it is recommended that they be added sparingly. Always conduct research on an essential oil you are considering for your cosmetic or toiletry products. There are a few great books out there or a google search will probably give you all the information you need, especially from supplier sites.
