Hydroxyethyl Acrylate
What is Hydroxyethyl Acrylate?
Hydroxyethyl acrylate is a synthetic, colorless liquid monomer chemically classified as an ester of acrylic acid and 2-hydroxyethanol. In cosmetic products, it undergoes polymerization to form copolymers widely used in skincare formulations such as serums, gels, lotions, and creams. These polymers serve as rheology modifiers, creating a stable, high-viscosity network upon hydration that improves texture, spreadability, and sensory feel. They also act as emulsion stabilizers, preventing separation, and mild film-formers, depositing a flexible layer on skin to aid moisture retention and enhance active ingredient delivery. Commonly featured in clear, aqueous-based products, it enables lightweight, non-greasy consistencies favored in modern cosmetics.
