Application

Chitosan (200-600mPa·s, 0.5% in 0.5% Acetic Acid at 20°C) serves as a versatile and effective ingredient valued for its various beneficial properties in cosmetics and pharmaceuticals. This film-forming polysaccharide is odorless and appears as either a white or creamy-white powder, sometimes looking 'cotton-like' during fiber formation. It enhances skin moisture retention by preventing transepidermal water loss and can bind other ingredients to increase their availability to the skin, such as improving liposome stability. Known for its antibacterial properties, chitosan also contributes to the microbiological stability of preparations. Studies show it can boost the water resistance of sunscreens and prolong the scent longevity in fragrances. Acting as a skin conditioner, chitosan improves skin softness and is commonly found in moisturizers, sunscreens, acne treatments, and hair care products. Derived from shrimp shells, it is a cationic polymer prepared through the deacetylation of chitin. This enhances its biodegradability, biocompatibility, and antibacterial activity, making it suitable for numerous applications. In pharmaceuticals, chitosan is used in various drug delivery systems, including controlled drug delivery, mucoadhesive dosage forms, and gene delivery, processed into gels, films, beads, microspheres, tablets, and liposome coatings through techniques like spray-drying and granulation.
