OCTAHYDRO-PENTAMETHYL-INDENE

Description

Octahydro-pentamethyl-indene is a synthetic fragrance ingredient commonly used in skincare and personal care products. This colorless to pale yellow liquid compound belongs to the family of polycyclic musk fragrances and is known for its long-lasting, woody-amber scent profile. Its molecular structure consists of a saturated indene ring with five methyl groups attached, providing stability and resistance to oxidation.

In skincare formulations, octahydro-pentamethyl-indene serves primarily as a fragrance enhancer, imparting a subtle, pleasant aroma to products. It is often used in low concentrations due to its potent olfactory properties. This ingredient has a low volatility, which contributes to its ability to provide a lingering scent in various formulations.

While primarily used for its fragrance properties, octahydro-pentamethyl-indene also exhibits some fixative qualities, helping to stabilize and prolong the overall scent of a product. It is generally considered safe for use in cosmetics when applied at recommended concentrations. However, as with any fragrance ingredient, it may cause sensitization in some individuals with sensitive skin or fragrance allergies.
