TETRAHYDRO-HEXAMETHYL-AS-INDACEN-3-ONE

Description

Tetrahydro-hexamethyl-as-indacen-3-one, also known by its trade name Amber Xtreme™, is a potent synthetic fragrance ingredient used in high-end perfumery and personal care products. This molecule belongs to the amber odorant family and is prized for its powerful, long-lasting woody-amber scent profile. In skincare and haircare formulations, it serves as a fixative, enhancing the longevity of other fragrance components and providing a deep, warm base note to the overall scent composition.

The compound's molecular structure allows for slow evaporation, contributing to its excellent tenacity on the skin and hair. It is particularly effective in leave-on products such as lotions, serums, and hair styling products. Tetrahydro-hexamethyl-as-indacen-3-one is known for its stability across a wide pH range and compatibility with most cosmetic ingredients, making it versatile for various formulations.

While primarily used for its olfactory properties, this ingredient may also contribute to masking less desirable odors in natural or active ingredient-rich formulations. Its potency allows for use at low concentrations, typically between 0.1% to 1%, depending on the desired intensity and product type. As with all fragrance ingredients, patch testing is recommended to ensure individual tolerance.
