Propylene Glycol Ceteth-3 Acetate

What is Propylene Glycol Ceteth-3 Acetate?

Propylene Glycol Ceteth-3 Acetate is a synthetic compound formed by combining propylene glycol with ceteth-3, a short-chain ethoxylated cetyl alcohol, and then acetylating it. This creates a versatile ingredient in the ethoxylated ester family, primarily used in leave-on skincare products like moisturizers, lotions, and serums. It functions as an emollient by mimicking natural skin lipids to fill in surface imperfections, promoting a smoother texture and enhanced slip during application. Additionally, its surfactant-emulsifying properties help blend oil and water phases, preventing separation and ensuring even distribution of active ingredients. With a non-comedogenic profile, it supports formulations for everyday use without clogging pores, providing a lightweight feel that absorbs quickly without greasiness.
