What is Alpha-Isomethyl Ionone?
Alpha-Isomethyl Ionone is a synthetic fragrance ingredient commonly used in a variety of personal care products and perfumes. It is created through the chemical synthesis of ionone, incorporating isomers to yield distinct scent profiles.
This compound is valued for its sweet, floral aroma reminiscent of violets, which is why it is frequently used to add or enhance fragrance in cosmetic products. The evidence on its health impact is primarily related to skin sensitivity; some individuals may experience allergic reactions upon exposure to it.
When seen on a label, Alpha-Isomethyl Ionone indicates the presence of added fragrance and consumers with sensitive skin may want to perform a patch test or consult if they've experienced reactions to similar compounds before.
Commonly found in: perfumes, lotions, shampoos, conditioners, deodorants
