TRIMETHYL-5,7-DECADIEN-2-ONE

Description

TRIMETHYL-5,7-DECADIEN-2-ONE, also known as Hexatriensal, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This compound belongs to the family of aliphatic ketones and is characterized by its floral, fruity scent with subtle green and woody undertones. Its molecular structure consists of a linear chain with three methyl groups and two double bonds, contributing to its unique olfactory profile.

In skincare formulations, TRIMETHYL-5,7-DECADIEN-2-ONE serves primarily as a fragrance enhancer, imparting a pleasant aroma to products without significantly affecting their functional properties. It is often used in low concentrations, typically below 1%, to achieve the desired scent without causing skin irritation in most individuals.

This ingredient is stable in various cosmetic bases and compatible with a wide range of other skincare components. While it does not offer direct skin benefits, its inclusion can improve the overall sensory experience of skincare products, potentially increasing user compliance and satisfaction. However, as with any fragrance ingredient, it may cause sensitization in some individuals with fragrance allergies. Formulators should consider this when developing products for sensitive skin types or fragrance-free lines.
