ACETYL HEXAMETHYL TETRALIN

Description

Acetyl Hexamethyl Tetralin, also known as Tonalide or AHTN, is a synthetic musk commonly used in personal care products and fragrances. This ingredient belongs to the polycyclic musk family and is prized for its long-lasting, woody-floral scent profile. In skincare formulations, it serves primarily as a fixative and fragrance enhancer, helping to stabilize and prolong the overall scent of a product.

From a dermatological perspective, Acetyl Hexamethyl Tetralin is generally considered safe for topical use at regulated concentrations. However, it has raised some environmental concerns due to its potential bioaccumulation in aquatic ecosystems. In skincare, it is typically used in low concentrations, ranging from 0.1% to 1% in leave-on products and up to 2.5% in rinse-off formulations.

While not directly beneficial for skin health, this ingredient contributes to the sensory experience of skincare products, potentially improving user compliance and satisfaction. It's important to note that individuals with fragrance sensitivities may react to products containing this synthetic musk. As with any fragrance component, patch testing is recommended for those with sensitive skin or a history of allergic reactions to scented products.
