Carbomer | 9007-20-9
Khoom Description
Polyacrylic acid thiab nws cov derivatives yog siv rau hauv cov ntaub so ntswg pov tseg, ion pauv resins, adhesives, thiab detergents. Cov tshuaj detergents feem ntau yog copolymers ntawm acrylic acid uas yuav siv tau nyob rau hauv ob qho tib si zeolites thiab phosphates nyob rau hauv ntxuav hmoov formulations. Lawv kuj tseem nrov ua cov thickening, dispersing, suspending, thiab emulsifying cov neeg ua hauj lwm nyob rau hauv pharmaceuticals, tshuaj pleev ib ce, thiab xim. Hla-txuas polyacrylic acid kuj tau siv los ua cov khoom siv hauv tsev, suav nrog cov tshuaj ntxuav hauv pem teb.
