TETRAMETHYLNONA-6,8-DIEN-3-ONE

Description

TETRAMETHYLNONA-6,8-DIEN-3-ONE, also known as Damascone Alpha, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This compound belongs to the family of damascones, which are aromatic ketones that mimic the scent of rose and fruit. Its molecular structure consists of a nine-carbon chain with two double bonds and four methyl groups, contributing to its unique olfactory properties.

In skincare formulations, TETRAMETHYLNONA-6,8-DIEN-3-ONE is primarily utilized for its pleasant fragrance, imparting a subtle, fruity-floral aroma to products. It is often found in low concentrations, typically below 1%, to enhance the sensory experience without overpowering other active ingredients. This compound has a relatively low molecular weight, allowing for easy incorporation into various product bases.

While primarily used for its scent, some studies suggest that TETRAMETHYLNONA-6,8-DIEN-3-ONE may possess mild antimicrobial properties, potentially contributing to product preservation. However, its primary function remains fragrance enhancement. As with many fragrance ingredients, patch testing is recommended for individuals with sensitive skin or known fragrance allergies to ensure compatibility.
