Chitosan is a remarkable ingredient found in cosmetics, renowned for its natural and multifunctional properties. Derived from chitin, a substance found in the exoskeletons of crustaceans like shrimp and crabs, chitosan is harnessed for its skincare benefits. With its high biocompatibility, chitosan becomes a favorable choice for cosmetics. It forms a protective film on the skin, locking in moisture and shielding it from environmental aggressors. Moreover, chitosan boasts excellent adhesion and film-forming properties, making it an ideal component in cosmetics like creams and lotions.
Origin
Chitosan is manufactured by first collecting crustacean shells and then subjecting them to a demineralization step using acid to remove inorganic components. Next, an alkaline treatment is applied to deproteinize the shells, leaving behind chitin. Finally, chitin is further processed through deacetylation, resulting in chitosan.
Safety profile
Chitosan is considered safe for most people when used appropriately. As a natural substance derived from crustacean shells, it is generally non-toxic and biocompatible. However, individuals with shellfish allergies should exercise caution, and it's always advisable to follow product instructions and consult a healthcare professional before using chitosan-based products.
