What is Carboxymethyl Chitosan
The medical alias of carboxymethyl chitosan is carboxymethyl chitosan. It is called chitosan because it is the only positively charged alkaline polysaccharide in nature and is widely found in shrimps, crabs, and insects. in the shells of crustaceans. Chitosan is its general name. Its name in the cosmetic ingredient list is carboxymethyl chitosan. It has good biocompatibility, non-cytotoxicity and is degradable. It has many effects such as antibacterial, promoting repair, chelating heavy metals, calming and soothing, inhibiting scars, etc., and is widely used in medicine, chemical industry, cosmetics and other fields.

Features
1. Moisturizing: Chitosan has strong moisturizing properties, and its moisturizing ability even exceeds that of sodium hyaluronate. It is known as a “super moisturizer”. It can quickly nourish epidermal cells and continuously replenish skin moisture while helping the cells to become elastic.
2. Repair: It has the function of repairing the skin barrier and is useful for sensitive skin and acne-prone skin. Speaking of repairing power, chitosan was first used in the medical field. It can quickly repair wounds, and has antibacterial properties to prevent wound infections. Therefore, high-purity chitosan is very popular among surgeons.
3. Antibacterial activity: The characteristics of polycation are mutual adsorption with the surface of negatively charged bacterial cells, and its antibacterial activity becomes stronger as the number of amino groups increases. It is a good ingredient for acne-prone skin and oily skin.
4. Adsorption: It can absorb heavy metals. In layman’s terms, it can absorb residues in cosmetics. In layman’s terms, it can absorb residues in cosmetics. This is a very noteworthy ingredient for most girls (especially those who often wear makeup). After chitosan absorbs heavy metals in cosmetics, it can reduce the impact of cosmetics on the skin. s damage.
5. Biocompatibility and film-forming properties: It has excellent biocompatibility and film-forming properties and can fully maintain nutrients: cosmetics added with chitosan can form a layer of bionic skin on the human epidermis. It has good permeability and can fully maintain the active ingredients in cosmetics such as moisturizers and nutrients. In addition, the chitosan film will form a barrier on the human epidermis, which can block or weaken the damage to the skin by ultraviolet rays and germs.
Applications
Carboxymethyl chitosan is also known as deacetylated carboxymethyl chitosan. In addition to its unique moisturizing and emollient properties, carboxymethyl chitosan also has excellent film-forming, hair-fixing, conditioning and stability properties. It is An ideal cosmetic raw material. Bozhihuili carboxymethyl chitosan can be compounded with various surfactants in cosmetics, which provides a wide range of applications for cosmetic formula design.
