Polyacrylate-4

Polyacrylate-4 (CAS 228863-31-8) is a synthetic acrylic polymer used in personal care and industrial formulations to control flow behavior and modify surface interactions.

Where is Polyacrylate-4 used?

• Skin care and color cosmetics: rheology modifier that builds viscosity in emulsions, gels, and serums without compromising skin feel
• Sunscreen and leave-on formulations: suspends active ingredients
• Coatings: supports controlled flow and leveling during application, reducing sagging in architectural and industrial paint systems
• Adhesive and sealant systems: tunes open time and application consistency in water-based systems
• It helps maintain product stability across temperature cycles.

Good to know: Cosmetic-grade material is the primary commercial form, aligned with INCI usage in personal care applications. Industrial grades suited for coatings and adhesive systems are also available, with concentration and pH specifications varying by supplier.
