Chitosan Hydrochloride -CAS 9012-76-4
Chitosan Hydrochloride is a high-purity natural water-soluble cationic biological polymer extracted from marine crustacean shells via deacetylation and hydrochloric acid modification. Breaking the water-insoluble defect of ordinary chitosan, this product features rapid water solubility, no organic solvent required, and excellent formula compatibility.
It integrates biological film formation, skin barrier repair, antibacterial soothing, moisturizing locking water and auxiliary fixing functions in one. It can form a uniform, soft, breathable and biocompatible protective film on skin and hair surface, effectively repairing damaged skin barriers, relieving redness, dryness and sensitivity, and inhibiting the reproduction of harmful bacteria on the skin surface.
In makeup formulas, it improves powder adhesion, enhances makeup fitting degree, and realizes moisturizing and non-dry long-wear effect. In hair care formulas, it adsorbs firmly on hair scales, reduces static electricity and frizzy hair, softens hair texture and achieves natural lasting shaping effect. With pure natural source, ultra-mild low irritation, good biodegradability and wide pH stability, it is a core high-value functional raw material for sensitive skin care, medical-grade soothing products and clean biological cosmetics.
Key Benefits
• 100% Water-soluble, Easy Formula Operation: Unique hydrochloric acid modified structure realizes full water solubility, no heating or organic solvent required, disperses rapidly in water phase, simplifies production process and improves formula efficiency.
• Biological Barrier Repair & Sensitive Soothing: Natural cationic polysaccharide structure fits skin physiology perfectly, repairs damaged skin barrier, relieves redness, dry itching and sensitivity, suitable for postoperative and fragile skin care.
• Natural Antibacterial & Mild Anti-inflammatory: Effectively inhibits the growth of harmful bacteria on skin and hair surface, reduces skin inflammation problems, improves product anti-mildew and anti-corrosion stability, and optimizes skin microecology.
• Soft Breathable Film-forming & Moisture Locking: Forms thin and flexible biological protective film without tightness or heavy residue, locks skin and hair moisture for a long time, improves dry and dull texture, and maintains moist and smooth state.
• Assist Makeup Fitting & Hair Soft Styling: Optimizes skin surface smoothness, enhances powder pigment adhesion, prevents dry lines and floating powder; smooths hair scales, eliminates static frizz, and realizes natural fluffy soft shaping.
• Natural & Safe, Wide Compatibility: Pure natural marine biological source, non-toxic and harmless, low allergenicity, good biodegradability, stable in wide pH range, compatible with most cosmetic raw materials, compliant with clean beauty standards.

Frequently Asked Questions (FAQ)
• Q1: What is the core advantage compared with ordinary chitosan?
A1: Ordinary chitosan is insoluble in water and only soluble in acidic solvents, with complex production operation; Chitosan Hydrochloride is fully water-soluble, no acid-base adjustment or organic solvent required. It retains all biological activities of chitosan, with better solubility, higher formula stability and wider application scenarios, more suitable for mild cosmetic formulas.
• Q2: What is the recommended formula addition ratio?
A2: 0.1%-1.0% for soothing repair skincare products, 0.2%-1.5% for antibacterial functional cosmetics, 0.1%-0.8% for long-wear base makeup, 0.2%-1.2% for hair care styling products, adjustable according to formula repair, antibacterial and shaping requirements.
• Q3: Is it suitable for sensitive skin and postoperative repair formulas?
A3: Yes. This product is natural marine biological raw material, ultra-mild and low-allergenic, with excellent barrier repair and anti-inflammatory soothing effects. It complies with medical-grade safety standards, and is specially suitable for sensitive skin, hormone face and postoperative fragile skin maintenance formulas.
• Q4: Will it cause stickiness or heavy film feeling?
A4: No. It forms ultra-thin, soft and breathable biological film, with light texture and no heavy accumulation. It has moderate moisturizing and fixing capacity, refreshing and dry skin feel, without stickiness, tightness or greasy residue.
• Q5: What is the difference between this product and polyurethane film-forming agents?
A5: Polyurethane series focus on physical wear resistance, waterproof and strong holding performance; Chitosan Hydrochloride is a biological functional polymer, focusing on barrier repair, antibacterial soothing and microecological balance, with natural mild characteristics, filling the gap of biological repair-type film-forming raw materials in cosmetic formulas.
• Q6: Does it support stable bulk supply and technical services?
A6: Standardized high-end cosmetic/medical grade production with stable batch deacetylation degree and film-forming performance, sufficient inventory, supports long-term bulk supply and global export, and provides professional formula debugging, sensitive skin soothing system and biological film effect optimization technical support.
