Propylene Glycol Isoceteth-3 Acetate description

Propylene glycol isoceteth-3 acetate is a synthetic ester that serves various functions in skin care products, including as a skin conditioning ingredient and emulsifier (meaning that it helps keep oil and water formulas from separating). It also has a “blooming” property that means it works well as a pigment wetter, particularly in liquid foundations. In its raw form, propylene glycol isoceteth-3 acetate is a clear, white, or pale yellow liquid. Usage levels range from 8–15% when used as an emulsifier. Although a formal safety assessment hasn’t been done for this ingredient, its “parent” ingredient propylene glycol is considered safe as used in cosmetics.
