Kev Siv
Kev pab tshuaj (tsheb, roj).
Isopropyl palmitate yog ib yam khoom uas ua rau daim tawv nqaij mos thiab noo noo, nws kuj ua haujlwm ua ib yam khoom khi thiab ua kom yaj. Zoo ib yam li isopropyl myristate, nws yog tsim los ntawm kev sib xyaw ntawm palmitic acid (txiv maj phaub lossis roj xibtes) thiab isopropyl cawv. Cov enzymes muaj peev xwm ua rau cov khoom xyaw no zom tau thiab kev tshawb fawb tsis qhia txog kev ua xua lossis kev lom. Qee qhov chaw qhia txog qhov muaj peev xwm ua rau daim tawv nqaij mos.
Isopropyl palmitate yog siv los tsim thiab soj ntsuam qhov kev tsim nyog ntawm pluronic lecithin organogels uas muaj flurbiprofen rau kev siv sab nraud thiab los piav qhia txog cov kab ke microemulsion ntawm isopropyl palmitate, dej thiab 2: 1 Brij 97, thiab 1-butanol los ntawm ntau yam kev sim.
Ntim thiab Xa Khoom
180KG / Nruas.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Isopropyl palmitate tiv taus oxidation thiab hydrolysis, thiab tsis ua rancid. Nws yuav tsum tau khaws cia rau hauv lub thawv kaw zoo, siab tshaj 16 ° C, thiab tiv thaiv kom tsis txhob muaj lub teeb.
