HEXAHYDRO-TETRAMETHYL-EPOXY-METHANOAZULENE

Description

Hexahydro-tetramethyl-epoxy-methanoazulene is a synthetic fragrance ingredient commonly used in both skincare and haircare formulations. This complex molecule belongs to the family of polycyclic musk compounds and is known for its long-lasting, woody-amber scent profile. In skincare and haircare products, it serves primarily as a fixative, helping to stabilize and prolong the overall fragrance of the formulation.

This ingredient is particularly valued for its ability to impart a subtle, clean aroma that doesn't overpower other scent components. Its molecular structure allows for slow evaporation, contributing to the longevity of the fragrance in the final product. Hexahydro-tetramethyl-epoxy-methanoazulene is often used in low concentrations, typically below 1% in leave-on products and up to 5% in rinse-off formulations.

While primarily utilized for its olfactory properties, some studies suggest potential antimicrobial benefits, which could contribute to product preservation. However, as with many synthetic fragrances, it may cause skin sensitization in a small percentage of individuals. Formulators should consider patch testing and adhere to regulatory guidelines regarding its use in cosmetic products.
