Application

Chitosan, available as a powder or flakes and characterized by its odorless and white or creamy-white appearance, serves as an integral ingredient known for its film-forming abilities, effectively enhancing skin's moisture retention by minimizing transepidermal water loss. It acts as a binding agent, improving the stability and efficacy of other active ingredients in skincare formulations. Recognized for its antibacterial properties, chitosan contributes to the microbiological stability of various products. Studies suggest its role in augmenting the water-resistance of sunscreens and prolonging the scent duration of fragrances. As a skin conditioner, it enhances softness and suppleness without leaving a tacky residue, making it a valuable component in moisturizers, acne treatments, and hair care products. Derived from chitin, primarily sourced from shrimp shells, chitosan provides a high adsorption capacity owing to its NH2 and OH groups, enabling heavy metal ion chelation. Commercially, it is formed through the N-deacetylation of chitin in an alkaline medium, and due to its unique solubility in aqueous acidic solutions, it is exploited in diverse applications, including pharmaceuticals, where it has been studied for controlled drug delivery, mucoadhesive dosage forms, and peptide delivery systems. Versatile in form, chitosan is employed in tablets, films, gels, and coatings, processed through methods like spray-drying, coacervation, and direct compression, highlighting its potential in both cosmetic and pharmaceutical industries.
