Chitosan Powder

INCI Name: CARBOXYMETHYL CHITOSAN Molecular Formula: C20H37N3O14 Molecular Weight: 543.52 Appearance: White fine powder Purity: 98% CAS NO.: 83512-85-0 EINECS No.: 695-802-6 Application: cosmetics and skin care products Supplier: ZHENYIBIO Carboxymethyl chitosan in cell anti-inflammatory experiments,it can significantly reduce IL6 and TNF�± levels.It also shows anti-inflammatory effects in human experiments; animal experiments promote skin stratum corneum Forming cell generation, accelerating the repair of the skin surface stratum corneum, indicating that it has a skin barrier repair function; it can quickly alleviate the itching of the skin caused by histamine, and significantly alleviate the tingling sensation caused by skin allergies. Animal experiments have confirmed its antipruritic effect.

Chitosan 90% High Density is made from shrimp and crab shell; it is a biodegradable and biocompatible material that has several unique properties such as biodegradability, and biocompatibility. High-density chitosan has 2-3 times the density (â?¥0.6g/ml) of ordinary chitosan, and its ability to absorb grease is more than 3 times that of ordinary chitosan at the same volume. These properties make it suitable for various applications including biomedical, agricultural, and environmental. In the field of biomedical engineering, chitosan is used in wound healing, drug delivery, tissue engineering and as a coating for medical devices.

Carboxymethyl chitosan is a higher derivative of chitosan obtained by reacting chitin with chloroacetic acid under basic conditions. Compared with chitin, its physical and chemical properties are optimized, with 100% water solubility, film formation and strong heavy metal chelation. This neutral, pure natural and completely non-toxic product has shown superior characteristics in the fields of medical care, pharmaceutical industry and agriculture. At present, it has been applied in many aspects such as advanced cosmetic additives, heavy metal chelating agents, drug sustained release agents and plant growth agents.
