Ethyl acrylate-methacrylic acid-polyethylene glycol stearyl ether methacrylate copolymer

Ethyl acrylate-methacrylic acid-polyethylene glycol stearyl ether methacrylate copolymer (CAS 75760-37-1) is an associative acrylic copolymer designed to control flow behavior and stabilize emulsions across aqueous formulation systems.

Its hydrophobically modified backbone allows it to build viscosity and structure in water-based systems without relying on high polymer loading. In personal care, it thickens and stabilizes lotions, creams, and leave-on treatments.

The polymer contributes to a smooth, non-tacky skin feel that formulators target in premium emulsions. Architectural and industrial coating manufacturers use it to prevent sagging and improve leveling in waterborne paint systems.

In household and institutional cleaning products, it suspends actives and particulates, maintaining product homogeneity through storage and use cycles. This ensures consistent performance for the end user over time.

Adhesive and sealant formulators incorporate it to adjust open time and application rheology in water-based systems. This copolymer is typically supplied as an aqueous dispersion or liquid emulsion, with solids content varying by grade.

Both neutralized and unneutralized forms are available, with the rheological response activated upon pH adjustment in formulation. Technical and cosmetic-grade specifications are the most commonly encountered in the market.
