Terpineol Acetate

What is Terpineol Acetate?

Terpineol Acetate is the acetic acid ester of terpineol, a naturally occurring monoterpene alcohol found in essential oils from pine, lavender, and other plants. Chemically, it appears as a colorless to pale yellow liquid with a sweet, lilac-like aroma. In cosmetics, it belongs to the fragrance category, primarily used in perfumes, lotions, creams, and shampoos. It functions by volatilizing at skin temperature to release its characteristic scent, contributing to the product's olfactory profile. As a masking agent, it overlays and neutralizes less desirable base notes from other ingredients, creating a more harmonious sensory experience. This compound is valued for its stability and subtlety in formulations, blending well without overpowering.
