Chitosan in Cosmetics The Ultimate Natural Film-Former & Moisturizer
01
Product Description
Chitosan is a natural polysaccharide derived from chitin through deacetylation, primarily obtained from the exoskeletons of crustaceans or fungal cell walls. Its chemical structure is a linear polymer of β-(1,4)-2-amino-2-deoxy-D-glucose, featuring abundant amino (-NH₂) and hydroxyl (-OH) groups. These groups endow it with excellent film-forming ability, moisturizing property, antibacterial activity, and cationic characteristics. As a biodegradable natural polymer, chitosan is widely used in functional skincare, haircare, and eco-friendly formulations, especially for sensitive skin, anti-aging, and repair products.
Aogebio® presents premium Chitosan, a natural biopolymer derived from crustacean shells that revolutionizes cosmetic performance through its unique film-forming, moisturizing, and protective properties. Specially processed for cosmetic applications, our Chitosan delivers exceptional bioadhesion, moisture retention, and antimicrobial benefits across skincare and haircare products.
Key Benefits of Aogebio® Chitosan:
✓ Intense Hydration Lock: Forms breathable films that reduce transepidermal water loss (TEWL)
✓ Smart Delivery System: Enhances penetration of active ingredients
✓ Natural Preservative Boost: Reduces reliance on synthetic antimicrobials
✓ Hair Repair Magic: Creates cationic films that repair damaged cuticles
✓ Eco-Conscious Performance: 100% biodegradable and sustainably sourced
Premium Applications Include:
• Long-lasting moisturizers with improved barrier function
• Anti-aging serums with enhanced active delivery
• Damage-repair hair masks and conditioners
• Acne treatments with natural antimicrobial action
• Sustainable makeup with improved wear time
Available in multiple molecular weights (50-2000 kDa) and deacetylation degrees (75-95%), Aogebio® Chitosan offers unparalleled formulation flexibility. Our technical team provides custom grade selection guidance to optimize performance in your specific applications.
Superior Film-Forming & Moisturizing Properties
Forms a breathable, flexible protective film on the skin to reduce water evaporation and enhance stratum corneum hydration, ideal for dry skin. Amino groups form hydrogen bonds with water molecules to strengthen moisture-locking capacity while blocking external pollutants.
Antibacterial & Anti-Inflammatory Effects
Its cationic nature allows adsorption to negatively charged bacterial cell membranes, disrupting bacterial structure and inhibiting the proliferation of microbes like Propionibacterium acnes (suitable for acne products).
Antioxidant & Anti-Aging Efficacy
Scavenges free radicals, inhibits lipid peroxidation, delays skin aging, and reduces fine lines. Promotes fibroblast synthesis of collagen to improve skin elasticity.
Adsorption & Purification Capability
Adsorbs skin surface oil, heavy metal ions, and dirt, commonly used in cleansing masks or oil-control products. Acts as a natural flocculant to purify impurities in lotions, enhancing product transparency.
01
Use
Recommended dosage: 0.1-2% (skincare), 0.5-3% (haircare); high concentrations may affect texture.
Preparation process: Disperse chitosan in acidic aqueous phase first, then emulsify with oil phase, avoiding high temperatures (>60°C) to prevent molecular structure damage.
01
Skincare Products
Forms a moisture-locking film, reduces transepidermal water loss; anti-inflammatory to repair barriers, relieves eczema/dermatitis.
01
Haircare Products
Cationic groups adsorb to negatively charged hair cuticles for repair; forms a protective film against UV/chemical damage and improves anti-static properties.
03
Suncare & Color Cosmetics
Enhances UV filter adhesion for prolonged sun protection; acts as a film former to improve makeup adherence and reduce smudging.
