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. It enables formulators to achieve precise viscosity profiles and improve the sensory or functional performance of finished products.

In skin care and color cosmetics, this polymer functions as a rheology modifier that builds viscosity in emulsions, gels, and serums without compromising skin feel. Sunscreen and leave-on formulations benefit from its ability to suspend active ingredients.

The material helps maintain product stability across temperature cycles, ensuring a consistent shelf life for consumer goods. In coatings, it supports controlled flow and leveling during application, reducing sagging in architectural and industrial paint systems.

Adhesive and sealant manufacturers use it to tune open time and application consistency in water-based systems. This versatility makes it a staple ingredient for technical formulators looking for reliable thickening and stabilization properties.

The product is typically supplied as a liquid dispersion or emulsion, ready for direct incorporation into aqueous formulations. 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. These grades ensure compatibility with a wide range of chemical environments and manufacturing processes.
