Description
Hydroxypropyl Chitosan (HPCS) is a slightly water-soluble derivative of chitosan obtained from natural chitin, featuring an 80% substitution degree. With an adjustable molecular weight between 100K and 200K, HPCS represents a highly functional and flexible biopolymer. Its hydroxypropyl modification improves dispersibility, stability, and surface activity, making it suitable for use in cosmetics, pharmaceuticals, and biomedical materials. Combining the inherent bioactivity of chitosan with enhanced solubility and processability, HPCS stands as a next-generation ingredient bridging natural polymer science and industrial performance.
