Original Title: Carboxymethyl Chitosan, a film-forming, moisturizing and anti-pollution active ingredient CARBOXYMETHYL CHITOSAN is a polysaccharide derived from marine organisms. Its molecular structure is as follows: Beta-1-4-straight chain glucose derivatives Disordered geometric arrangement of diglucose molecular Effective hydrophilic groups: carboxyl, acetamido Effective anti-corrosion group: amino Effective anti-aging groups: hydroxyl, amino Beta-1-4-straight chain glucose derivatives Disordered geometric arrangement of diglucose molecular Effective hydrophilic groups: carboxyl, acetamido Effective anti-corrosion group: amino Effective anti-aging groups: hydroxyl,jacketed glass reactor, amino Our carboxymethyl chitosan has two specifications. Expand the full text MHA Plus has excellent moisture and film-forming properties MHA Plus can significantly improve the loss of water in the epidermis of the skin through its strong film-forming property. At the same concentration, the ability of MHA Plus to reduce the water loss rate of skin epidermis is about twice that of hyaluronic acid with the same molecular weight. (SGS Third Party Testing) MHA Plus can significantly improve the loss of water in the epidermis of the skin through its strong film-forming property. At the same concentration, the ability of MHA Plus to reduce the water loss rate of skin epidermis is about twice that of hyaluronic acid with the same molecular weight. (SGS Third Party Testing) Moisturizing Mechanism of MHA Plus 1. Rheological properties: The dissociation of hydroxyl groups makes the carboxymethyl chitosan molecules in the solution in a state of mutual repulsion of negative ions,thin film distillation, with loose conformation, which can occupy the whole solution space at low concentration; at high concentration, they are intertwined to form a network structure, which endows the solution with special rheological properties and good film-forming properties. After being coated on the surface of the skin, it can form a layer of hydration film to keep the stratum corneum moisturized and prevent the skin from drying. 2. Because carboxymethyl chitosan is highly stretched and intertwined to form a continuous network structure, decarboxylation after extraction ,wiped film distillation, and water molecules are combined with it through polar bonds and hydrogen bonds in this network, it can absorb and maintain thousands of times its own mass of water. MHA Plus has the ability of pollution isolation, and its mechanism is that it can isolate PM2.5 pollutants, reduce the oxidative stress caused by PM2.5 pollutants, and reduce the mitochondrial toxicity caused by PM2.5 pollutants. When MHA Plus is compounded with polyols such as pentanediol, it has antiseptic and synergistic effects. Anticorrosive and synergistic mechanism of MHA Plus 1. Under acidic conditions, the protonated ammonium in the MHA Plus molecule is electropositive, adsorbs bacteria with negative charges, adheres to the surface of bacterial cell walls, interferes with the normal metabolism of cells, and inhibits bacterial reproduction. 2. After MHA Plus adsorbs bacteria, it passes through the porous cell wall (mainly composed of chitin) and enters the bacterial cells, which may form a stable complex with DNA, interfere with the action of DNA polymerase or RNA polymerase, hinder the synthesis of DNA or RNA, and thus inhibit the reproduction of bacteria. MHA Plus has the advantages of moisturizing, film-forming and anti-pollution,50l rotovap, and has a certain effect of anti-corrosion synergist. Apply the recommendations 1. The powder is recommended to be added after being pre-dispersed with polyol; 2. Consistent with HA, do not use with cationic surfactant or polymer such as JR-400 in transparent formula; 3. The suitable range of pH is 4.5 ~ 12; 4. Avoid long-term high-speed shearing; 5. Avoid long-term high temperature heating. For more details, please contact us.
