HEXAHYDRO-TETRAMETHYL-METHANOAZULEN-5-YL METHYL KETONE

Description

Hexahydro-tetramethyl-methanoazulen-5-yl methyl ketone, also known as Isolongifolene ketone, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This compound is derived from natural isolongifolene, a sesquiterpene found in various plant essential oils. It possesses a distinct woody, earthy aroma with subtle floral undertones, making it a versatile addition to fragrance formulations.

In skincare applications, hexahydro-tetramethyl-methanoazulen-5-yl methyl ketone serves primarily as a masking agent, helping to neutralize unpleasant odors associated with other active ingredients. Its molecular structure allows for slow evaporation, providing long-lasting fragrance effects in leave-on products such as moisturizers, serums, and body lotions.

This ingredient is generally considered safe for topical use when formulated at appropriate concentrations. However, as with any fragrance component, it may cause skin sensitization in some individuals. Formulators should be mindful of potential allergic reactions and adhere to recommended usage levels. Hexahydro-tetramethyl-methanoazulen-5-yl methyl ketone is often used in conjunction with other fragrance ingredients to create complex, appealing scent profiles in skincare products while maintaining their functional benefits.
