Hydroxypropyl Chitosan – Water-Soluble Biopolymer for Advanced Formulations
Brief Introduction
Revolutionize formulations with universal solubility! Our Hydroxypropyl Chitosan is a non-ionic, water-soluble biopolymer that eliminates the need for acidic solvents. Ideal for clean-beauty cosmetics, nutraceutical encapsulation, and food preservation, it delivers superior film-forming, moisturizing, and barrier-enhancing properties¹. Sourced from eco-friendly crustacean shells, it's your sustainable solution for high-performance products.

| Nutraceuticals | Probiotic microcapsules | 1-2% | Gastric acid resistance |
FAQ
Q: How does it differ from regular chitosan?
A: Unlike acid-soluble chitosan, HP Chitosan is water-soluble at neutral pH and compatible with anionic surfactants – ideal for clear gels⁹.
Q: Can it replace PVP in hair sprays?
A: Yes! Comparable hold with 100% biodegradability (OECD 301B)³. Use DS ≥0.8 for optimal film strength.
Q: MOQ for custom DS grades?
A: 50kg MOQ (Standard DS 0.6). 100kg MOQ for custom DS (0.2-1.0).
Q: Food safety compliance?
A: Meets FDA 21 CFR §173.20 for food coatings. EU EC 1223/2009 compliant for cosmetics.
