Product Description
Polyvinyl pyrrolidone (PVP luv luv) yog non-ionic polymer compound, uas yog qhov txawv tshaj plaws N-vinyl amide polymer
Qhov tob tshaj plaws thiab dav tshaj plaws tau kawm cov tshuaj zoo. Nws tau tsim rau hauv cov homopolymers, copolymers thiab cross-linked polymers nrog cov txheeb ze molecular hnyav li ntawm txhiab mus rau ntau tshaj ib lab nyob rau hauv peb pawg ntawm non-ionic, cationic thiab anionic, industrial, tshuaj thiab zaub mov qib, thiab tau dav siv rau nws cov kev ua tau zoo heev thiab tshwj xeeb.
Thaum Lub Kaum Hli 27, 2017, cov npe ntawm cov kab mob carcinogens luam tawm los ntawm Lub Chaw Haujlwm Thoob Ntiaj Teb rau Kev Tshawb Fawb Txog Kev Mob Cancer ntawm Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb (WHO) tau raug sau ua ntej thiab xa mus, thiab polyvinylpyrrolidone tau suav nrog hauv cov npe ntawm Qib 3 carcinogens.
