What it is
Cedryl Acetate is a synthetic ester produced by acetylating cedrol, a natural alcohol found in cedarwood oil. It is a clear, colorless to pale yellow liquid with a persistent woody odor.
How it works
In cosmetic products, Cedryl Acetate functions solely as a fragrance ingredient. It evaporates slowly from the skin, releasing its scent over time. It does not provide any active skincare benefits like moisturizing or anti-aging.
