Polyquaternium-2丨CAS 68555-36-2

Polyquaternium-2 (CAS 68555-36-2) is a cationic polymer widely used in personal care, cosmetic, and industrial formulations. In hair care products such as shampoos, conditioners, and styling gels, it serves as an antistatic and film-forming agent that enhances smoothness, shine, and manageability. In skin care formulations, it acts as a conditioning and moisturizing additive that improves skin feel and product spreadability. The polymer's strong cationic charge allows it to bind effectively to negatively charged surfaces such as hair and skin, providing long-lasting conditioning benefits even after rinsing. In the textile and paper industries, Polyquaternium-2 is utilized as a softener, antistatic agent, and retention aid, while in water treatment applications, it functions as a flocculant and dispersant to enhance purification efficiency.

Polyquaternium-2 offers excellent film-forming, conditioning, and antistatic properties, which make it an essential ingredient in high-performance formulations. Its cationic nature enables strong adhesion to keratin and cellulose fibers, leading to smoother textures, reduced static electricity, and improved softness. The polymer enhances the tactile and visual quality of hair and skin without leaving residue or greasiness. Furthermore, it exhibits high stability across a wide pH range and compatibility with anionic, nonionic, and amphoteric surfactants, allowing flexible formulation design. Its low toxicity and biodegradability make it suitable for sustainable and environmentally responsible applications.
