TRANS-2,4-DIMETHYL-2-(5,6,7,8-TETRAHYDRO-5,5,8,8-TETRAMETHYL-2-NAPHTHALENYL)-1,3-DIOXOLANE

Description

TRANS-2,4-DIMETHYL-2-(5,6,7,8-TETRAHYDRO-5,5,8,8-TETRAMETHYL-2-NAPHTHALENYL)-1,3-DIOXOLANE, commonly known as Acetyl Tetramethyltetralin, is a synthetic fragrance ingredient used in various skincare and personal care products. This compound belongs to the family of musk fragrances and is prized for its long-lasting, woody-amber scent profile.

In skincare formulations, Acetyl Tetramethyltetralin serves primarily as a fixative, helping to stabilize and prolong the overall fragrance of a product. Its molecular structure allows for slow evaporation, contributing to the longevity of the scent on the skin. While not directly involved in skin treatment, this ingredient enhances the sensory experience of skincare products, potentially improving user compliance and satisfaction.

It's important to note that Acetyl Tetramethyltetralin is a synthetic alternative to natural musk, addressing ethical and sustainability concerns associated with animal-derived fragrances. The ingredient is generally considered safe for topical use at recommended concentrations. However, as with any fragrance component, it may cause sensitivity in some individuals, particularly those with reactive skin. Formulators typically use this ingredient in small quantities, balancing its olfactory benefits with potential skin reactivity considerations.
