What it is
Amylcinnamyl Acetate is a synthetic ester derived from cinnamyl alcohol and amyl alcohol. It is a colorless to pale yellow liquid with a sweet, floral, jasmine-like odor. It is widely used in the fragrance industry as a scent component in perfumes, cosmetics, and personal care products.
How it works
In a cosmetic product, Amylcinnamyl Acetate serves solely as a fragrance ingredient. It does not provide any skincare benefits like moisturizing or anti-aging. Its role is to add or enhance a floral scent, making the product more pleasant to use. It works by evaporating from the skin and interacting with olfactory receptors in the nose.
