GAMMA-UNDECENOLACTONE

Description

Gamma-undecenolactone is a versatile synthetic fragrance ingredient widely used in cosmetics and personal care products. This colorless to pale yellow liquid compound belongs to the lactone family and is characterized by its fruity, peach-like aroma with subtle coconut undertones. Its chemical structure consists of an eleven-carbon chain with a unsaturated bond and a cyclic ester group.

In skincare formulations, gamma-undecenolactone serves primarily as a fragrance enhancer, imparting a pleasant scent to products. Its low molecular weight allows for good skin penetration, contributing to the longevity of the fragrance on the skin. This ingredient is generally considered safe for topical use and is approved by regulatory bodies for cosmetic applications.

Beyond its olfactory properties, gamma-undecenolactone exhibits mild antimicrobial activity, potentially contributing to product preservation. It also demonstrates solvent properties, aiding in the dissolution of other ingredients in formulations. While not typically used for its direct skin benefits, its inclusion in skincare products can enhance the overall sensory experience for users.

When formulating with gamma-undecenolactone, careful consideration of concentration is essential to avoid potential skin irritation in sensitive individuals. Typical usage levels range from 0.1% to 1% in leave-on products.
