Polyquaternium 7(CAS: 26590-05-6)

Polyquaternium 7 (CAS: 26590-05-6) is a water-soluble polymer characterized by its crystalline form. It has a broad molecular weight range and exhibits good solubility in water. Chemically, it displays quaternary ammonium functionality, which makes it highly reactive towards nucleophiles. It is stable under normal conditions but can degrade under strong acidic or basic conditions.

Polyquaternium 7 (CAS: 26590-05-6) is synthesized through the polymerization of 2-vinylpyridine with quaternary ammonium compounds. Common synthesis methods include free radical polymerization, where initiators like benzoyl peroxide are used. The reaction is typically conducted in aqueous media, ensuring good solubility. The process yields high molecular weight polymers with a high degree of selectivity and good yields.

Polyquaternium 7 (CAS: 26590-05-6) is widely used in the cosmetic and personal care industries for its excellent water solubility and conditioning properties. It is also employed in the textile industry for softening and anti-static treatments. Additionally, it finds applications in pharmaceuticals for its antimicrobial properties and in polymer science for improving the mechanical properties of polymers.

When handling Polyquaternium 7 (CAS: 26590-05-6), it is essential to use personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be stored in a dry, well-ventilated area away from direct sunlight and heat sources. In case of a spill, the area should be immediately flushed with water, and appropriate safety data sheets (SDS) should be consulted for detailed spill cleanup procedures.
