stearicacid CAS: 57-11-4

Stearic acid siv tau dav hauv ntau yam lag luam, ua lub luag haujlwm tseem ceeb ua tus emulsifier thiab stabilizer hauv kev tsim cov khoom siv tu tus kheej, xws li tshuaj pleev, tshuaj pleev, thiab xab npum. Nws lub peev xwm los cuam tshuam nrog ob qho dej thiab roj theem ua rau muaj cov emulsions ruaj khov, ua kom ntseeg tau tias cov khoom xyaw sib xyaw thiab txhim kho cov qauv, tsos, thiab txee ruaj khov ntawm cov tshuaj pleev ib ce. Ntxiv mus, nws ua haujlwm ua tus neeg sawv cev tuab thiab opacifier hauv cov khoom siv tu tawv nqaij thiab plaub hau, pab txhawb rau cov yam ntxwv xav tau thiab pom thaum ua kom cov khoom muaj kev ncaj ncees thiab kev ua tau zoo. Hauv kev lag luam tshuaj, stearic acid yog siv ua tus neeg pabcuam hauv kev tsim cov ntsiav tshuaj, tshuaj ntsiav, thiab tshuaj pleev. Nws lub luag haujlwm ua lub roj nplua nyeem thiab kev pabcuam ntws pab txhawb kev ua thiab kev sib sau ua ke ntawm cov khoom xyaw tshuaj hmoov, ua rau muaj kev tsim cov tshuaj tshuaj ruaj khov thiab sib xws. Tsis tas li ntawd, nws ua haujlwm ua cov khoom siv hauv paus rau cov tshuaj suppository, qhov twg nws cov khoom yaj thiab biocompatibility txhawb nqa kev tso tawm ntawm cov khoom xyaw tshuaj nquag, daws cov kev xav tau kev kho mob tshwj xeeb thiab cov neeg mob nyiam. Ntxiv mus, stearic acid siv ua tus neeg sawv cev tso pwm, plasticizer, thiab stabilizer hauv kev tsim cov yas, cov khoom siv roj hmab, thiab cov ntaub ntawv polymeric. Nws cov khoom ua haujlwm ntawm qhov chaw ua rau nws ua haujlwm ua tus pab ua tiav, txhim kho cov khoom ntws thiab cov yam ntxwv ntawm cov yas sib xyaw, yog li txhawb nqa kev ua haujlwm ua yas zoo thiab zoo. Tsis tas li ntawd, nws ua haujlwm ua tus neeg hloov pauv viscosity thiab tus neeg sawv cev gelling hauv kev tsim cov roj, cov roj nplua nyeem, thiab cov kua hlau ua haujlwm, pab txhawb kev txo kev sib txhuam, kev tiv thaiv kev hnav, thiab kev ruaj khov thermal ntawm cov khoom lag luam no. Ntxiv mus, stearic acid ua lub luag haujlwm tseem ceeb hauv kev tsim cov stearates thiab cov xab npum hlau, uas siv ua cov khoom tuab, cov khoom ruaj khov, thiab cov neeg sawv cev tso tawm hauv ntau yam kev siv hauv kev lag luam suav nrog cov xim, cov txheej txheem, cov nplaum, thiab cov roj hmab sib xyaw. Nws kev sib cuam tshuam nrog cov hlau ions ua rau muaj cov khoom ruaj khov uas muab cov khoom zoo rheological thiab kev ua tau zoo rau cov khoom tsim, txhawb nqa lawv daim ntawv thov hauv ntau yam kev tsim khoom thiab cov txheej txheem tsim kho. Ntxiv mus, nws pom siv rau hauv kev tsim cov tswm ciab, cov xim pleev xim, thiab cov khoom siv ua los ntawm cov quav ciab, qhov twg nws pab txhawb rau qhov sib xws, tawv, thiab hlawv cov yam ntxwv ntawm cov khoom siv no. Hauv kev xaus, stearic acid yog cov khoom xyaw ntau yam nrog kev siv ua cov emulsifier, roj nplua nyeem, stabilizer, thiab kev pab ua haujlwm hauv kev lag luam xws li kev saib xyuas tus kheej, tshuaj, yas, thiab cov tshuaj tshwj xeeb. Nws cov kev koom tes rau kev tsim thiab kev ua tau zoo ntawm ntau yam khoom qhia txog nws qhov tseem ceeb hauv kev ua kom cov khoom siv ua haujlwm, kev ua haujlwm zoo, thiab kev txaus siab ntawm cov neeg siv khoom thoob plaws ntau qhov chaw.
