Taw qhia ntawm CAS: 83512-85-0|Carboxymethyl chitosan
Carboxymethyl chitosan, dej-soluble chitosan derivative, yog amphoteric polyelectrolyte, uas yog tsim los ntawm kev qhia cov hydrophilic pawg -CH2COOH rau hauv chitosan polymer saw. Tom qab hloov kho carboxymethylation, chitosan tuaj yeem txhim kho nws cov cuab yeej dej-soluble Chemicalbook, tshwj xeeb tshaj yog nws cov solubility hauv nruab nrab thiab alkaline daws tau zoo dua. Nws muaj cov yam ntxwv ntawm zaj duab xis tsim, thickening, moisturizing, chelating, thiab lwm yam, yog li nws yog dav siv hauv kev ua liaj ua teb, tshuaj, khoom noj qab haus huv, tshuaj pleev ib ce, kev txuag, kev tiv thaiv ib puag ncig thiab lwm yam.
