ACULYN™ 28 POLYMER (Acrylates/Beheneth-25 Methacrylate Copolymer and Water) is a cutting-edge anionic associative rheology modifier expertly crafted for both hair and skin care applications. This innovative thickener is a hydrophobically modified alkali soluble polymer emulsion (HASE), renowned for its remarkable aqueous thickening and stabilizing efficiency. As a liquid, cold-processable product, it rapidly thickens upon neutralization, promoting ease of handling and enhancing manufacturing efficiency. Designed for clarity and stability across a pH range of 5.5 to 10, this versatile polymer is compatible with a variety of ingredients, including nonionic, anionic, zwitterionic, and some cationic compounds, as well as peroxide and electrolytes, making it particularly advantageous for skin care formulations. Its optimized lower pH neutralization makes it especially suitable for creating effective and luxurious skin care products that deliver both stability and performance.
