Hydroxypropyl Chitosan

Hydroxypropyl chitosan is a derivative modified from chitosan, which retains the alkalinity and positive charge of chitosan and improves its performance by introducing hydroxypropyl groups. This modification makes hydroxypropyl chitosan have good moisturizing, antibacterial, adsorbent, cross-linking, biocompatibility and degradability, and is widely used in cosmetics, medicine, water quality and environmental protection and other fields.

● Enhanced water solubility and moisturizing properties:

By introducing hydroxypropyl groups, the water solubility of HPCS is significantly improved. At the same time, hydrophilic groups such as hydroxyl and amino groups in its macromolecular structure enhance its moisture absorption and moisturizing capabilities.

● Antibacterial properties: 

Retaining the natural antibacterial properties of chitosan, HPCS can inhibit the growth of a variety of bacteria, which makes it valuable for use in wound dressings, antibacterial textiles and daily chemicals.

● Antioxidant:

HPCS contains active amino and hydroxyl groups, which have a strong ability to scavenge free radicals and help protect cells from oxidative damage. This is particularly important in skin care products, which can improve skin condition and prevent aging.

● Sustained and controlled drug release:

The special chemical structure of HPCS enables it to control the drug release rate and is suitable for the development of long-acting or targeted drug delivery systems to improve drug treatment efficiency.

● Biocompatibility and safety:

Due to its biocompatibility, HPCS shows good safety and reduces rejection reactions when used as a drug carrier, tissue engineering material or wound healing auxiliary material in the medical field.
