What is Chitosan?
Chitosan (chitosan), also known as deacetylated chitin, is obtained by deacetylation of chitin, which is widely existed in nature. The chemical name is polyglucosamine (1-4) -2-amino-B-D glucose.
Chitosan is an important natural biopolymer material commonly used in medicine, food, agriculture and other fields. There are two sources of chitosan: shrimp and crab shell extraction and mushroom source. The process of refining chitosan includes decalcification, deproteinization, chitin, and deacylation, and finally chitosan is obtained. These steps ensure high-quality chitosan extraction from shrimp and crab shells.
The properties and properties of chitosan make it widely used in many different fields. Due to the amino and cationic nature of its molecule, chitosan has several important properties:
1.Biocompatibility: Chitosan has good biocompatibility for humans and animals, and is suitable for drug delivery systems, biomaterials and other applications in the medical field.
2.Gel formation: Under acidic conditions, chitosan can form gels and is used in scaffold materials, tissue engineering, and drug delivery systems.
3.Antibacterial properties: Chitosan exhibits antibacterial activity against bacteria and fungi and can be used in antibacterial materials, food packaging and medical equipment.
4.Moisturizing properties: Chitosan has good moisturizing properties and can be used in cosmetics and skin care products.
Based on these properties, chitosan is widely used in medicine, food, cosmetics, agriculture and other fields.
Skin care effect of chitosan
1.Detoxification: urban women often need to apply foundation, BB cream, etc., chitosan can play the role of adsorption and excretion of heavy metals under the skin.
2.Super moisturizing: Improve skin moisture retention, maintain skin water content at 25%-30%.
3.Improve immunity: the Gospel of thin skin girls, for fragile and sensitive skin can improve skin immunity in daily care.
4.Calming and soothing: soothes sensitive muscles with dry oil, reduces pore blockage, and maintains water and oil balance.
5.Repair barrier: After radiofrequency, dot matrix, hydroxy acid and other medical cosmetic procedures, chitosan can help the skin to resist sensitivity and inflammation, quickly repair the basal heat damage, and avoid postoperative sensitivity. There are some functional dressings that have a great effect on the repair of wounds after medical art.

What is the effect of chitosan?
Freshmen capacity of Chitosan:
Some creatures in nature have the ability to "regenerate skin" : Shrimp shell, crab shell they contain rich chitin, the damaged skin can be naturally recovered, chitosan is extracted from this inside, medical applications have also proved that it can promote coagulation and wound healing, can be degraded and absorbed by the human body, with immune regulatory activity, chitosan can repair damaged cells and allergic skin, activate cells, accelerate new cell growth, so that it always help keep young.
Biocompatibility and degradability of Chitosan:
As fiber components in lower animal tissues, from the perspective of macromolecular structure, they are similar to the fiber structure in plant tissues and the collagen structure in higher animal tissues. Therefore, they not only have several biocompatibilities with the human body, but also can be broken down into glycogen proteins by the dissolved enzymes in the biological body for absorption by the human body.
Safety of Chitosan:
Through a series of toxicological tests, such as acute toxicity, subacute toxicity, chronic toxicity, Am field test, chromosome malformation test, embryo toxicity and teratogen test, bone marrow cell micronucleus test, chitosan has been shown to be non-toxic to humans.
