Mono propylene Glycol Khoom noj khoom haus qib CAS NO. 57-55-6
Propylene glycol muaj peev xwm yaj tau zoo rau cov xim zaub mov, thiab tsis hloov pauv thiab pheej yig tom qab ntxiv, yog li nws yog cov kuab tshuaj zoo tshaj plaws rau cov zaub mov xim.Cov emulsifying thiab moisturizing zog ntawm propylene glycol tau siv dav hauv kev tsim cov khob cij thiab khoom qab zib txawv teb chaws. Tsis tas li ntawd, vim nws cov khoom emulsifying, lub sijhawm ua mov ci tuaj yeem ua kom luv. Thaum propylene glycol ntxiv rau lub khob cij, nws yooj yim rau nqus dej noo hauv huab cua, yog li nws tuaj yeem tiv thaiv cov qhob cij thiab cov ncuav mog qab zib. Propylene glycol muaj peev xwm ua kom tsis muaj menyuam, thiab nws tuaj yeem siv los ua cov tshuaj tua kab mob thiab ua kom tsis muaj menyuam rau cov txiv hmab txiv ntoo, jams, pickled khoom, nqaij npua thiab hnyuv ntxwm.

Daim ntawv thov loj
Nyob rau hauv bread:Nws tuaj yeem siv los ua cov khoom siv ntxiv hauv kev ua mov ci, thiab tuaj yeem siv los ua cov khoom siv moisturizing hauv kev ua cov hmoov nplej thiab qhob cij. Tsis tas li ntawd, rau cov phooj ywg uas nyiam ci, propylene glycol yog cov khoom siv rau txhua tus, uas tuaj yeem pab cov ncuav mog qab zib zoo dua. saj thiab tsw.Nws tiv thaiv cov khoom xyaw zaub mov los ntawm kev sib cais, xws li roj thiab vinegar nyob rau hauv nyias hnav khaub ncaws.
Hauv cov khoom ua tiav:Propylene glycol muaj peev xwm ua kom tsis muaj menyuam, nws tuaj yeem siv los ua cov tshuaj tua kab mob thiab ua kom tsis muaj menyuam rau cov txiv hmab txiv ntoo, jams, pickled khoom, nqaij npua thiab hnyuv ntxwm. Cov khoom moisturizing thiab softening ntawm propylene glycol kuj tiv thaiv kev laus ntawm cov khoom noj marine. Thaum cov concentration ntawm propylene glycol ntau dua 10 feem pua, kev tsim tawm ntawm cov pwm hauv cov khoom noj kua dej tuaj yeem tiv thaiv tau, uas yog qhov zoo rau kev khaws cov khoom noj thiab kua txiv hmab txiv ntoo ntawm lub rooj.
Dosage thiab Solubility
Kev noj tshuaj: tuaj yeem siv rau ncuav mog qab zib, siv ntau tshaj 3.0g/kg.
Solubility:: Nws yog soluble hauv cov organic hnyav, xws li dej thiab ethanol.
Txee lub neej thiab cia:
Txee lub neej: 12 lub hlis nyob rau hauv unopened thawj ntim nyob rau hauv lub cia tej yam kev mob.Cia: Tsis txhob tshav ntuj, nag. Khaws rau hauv lub ntim tsis tawg ntawm qhov chaw txias, qhuav thiab zoo-ventilated. Qhov kub cia yuav tsum qis dua 25 degree kom ntseeg tau tias cov khoom zoo.
