TRIMETHYL-1-CYCLOHEXENYLBUTAN-2-ONE

Description

Trimethyl-1-cyclohexenylbutan-2-one, also known as Ionone, is a versatile synthetic fragrance compound widely used in both skincare and haircare formulations. This colorless to pale yellow liquid is characterized by its distinct woody-floral aroma with subtle violet undertones. Ionone is derived from the natural breakdown of carotenoids and serves as a crucial component in creating complex scent profiles.

In skincare applications, Ionone contributes to the olfactory experience of products while potentially offering mild antimicrobial properties. Its low molecular weight allows for efficient penetration through the stratum corneum, enhancing fragrance longevity on the skin. In haircare formulations, Ionone helps mask unpleasant odors associated with certain active ingredients and provides a pleasant, long-lasting scent to shampoos, conditioners, and styling products.

Ionone is generally recognized as safe (GRAS) by the FDA and is approved for use in cosmetics by the European Commission. However, as with any fragrance compound, it may cause sensitization in some individuals. Formulators typically use Ionone in concentrations ranging from 0.01% to 0.1% in leave-on products and up to 0.5% in rinse-off applications to achieve optimal fragrance performance without compromising product safety.
