Alpha Isomethyl Ionone

Description

Alpha Isomethyl Ionone is a synthetic fragrance ingredient commonly used in cosmetics and personal care products. This colorless to pale yellow liquid belongs to the chemical class of ionones and possesses a distinctive woody, floral scent with violet undertones. Its molecular structure allows for a long-lasting fragrance profile, making it a valuable component in perfumes and scented skincare formulations.

In cosmetic applications, Alpha Isomethyl Ionone serves primarily as a masking agent, helping to neutralize unpleasant odors associated with certain active ingredients. It also contributes to the overall sensory experience of products, enhancing consumer appeal. While generally considered safe for topical use, this ingredient has been associated with contact allergies in some individuals, particularly those with sensitive skin.

Formulators typically incorporate Alpha Isomethyl Ionone at concentrations ranging from 0.01% to 0.1% in leave-on products and up to 0.2% in rinse-off formulations. Its stability in various pH environments and compatibility with most cosmetic ingredients make it versatile for use in a wide range of product types, including lotions, creams, and body washes. However, due to potential sensitization concerns, its use is regulated in some regions, with restrictions on maximum concentration levels in finished products.
