Lub luag haujlwm ntawm propylene glycol hauv tshuaj pleev ib ce yog dab tsi?

Propylene glycol yog ib qho tshuaj reagent. Cov reagent no tsis paub ntau tus neeg. Qhov tseeb, nws muaj ntau yam kev siv.

Piv txwv li, nws tuaj yeem tshwm hauv cov tshuaj pleev ib ce. Lub luag haujlwm ntawm propylene glycol hauv tshuaj pleev ib ce yog dab tsi? Propylene glycol, hom khoom no yuav luag pom nyob rau hauv cov tshuaj pleev ib ce feem ntau vim nws yog cov khoom hnyav, cov hauv qab no yuav qhia txog lub luag haujlwm ntawm propylene glycol hauv tshuaj pleev ib ce.

Propyleneglycol yog insoluble hauv dej los yog glycerin; Nws tuaj yeem yaj hauv ethanol, 1, 2-propylene glycol, isopropanol, soybean oil, thiab lwm yam thaum cua sov. Nws cov qauv molecular yog dominated los ntawm pawg hydrophobic thiab belongs rau W / O hom emulsifier.

Tam sim no, txoj kev npaj tseem ceeb ntawm propylene glycol suav nrog kev ncaj qha hydration ntawm propylene oxide, tsis ncaj hydration ntawm propylene oxide, thiab ncaj qha catalytic oxidation ntawm propylene.

1. Propylene glycol yog ntxiv rau cov khoom tu tawv nqaij thiab feem ntau yog siv rau hauv cov tshuaj pleev ib ce thiab cov essences. Vim tias nws yog hom polyol, nws yog cov khoom siv me me moisturizing, uas tuaj yeem kaw hauv cov dej noo thiab ua lub luag haujlwm moisturizing, tab sis nws cov dej nqus dej kuj tsis muaj zog thiab moisturizing.

General nyhuv. Nws tuaj yeem pab kom nkag mus ntawm cov khoom xyaw nquag, thiab tseem tuaj yeem pab nrog cov tshuaj tua kab mob, tab sis nws ua rau khaus tawv nqaij thiab qhov muag.

2. 1,2-Propanediol muaj tus nqi qis dua, cov nyhuv antifreeze zoo dua, thiab qee yam tshuaj tua kab mob; 1. Feem ntau, feem ntau cov khoom tu tawv nqaij qis muaj 1 lossis 2 propylene glycols. Nco ntsoov xyuas cov khoom muaj npe thaum yuav khoom.

3. Hygroscopic propylene glycol, xws li cov tshuaj pleev ib ce, qhov ncauj qhov ntswg, lotions, tshuaj ntxuav lub ntsej muag, essences, pleev removers, moisturizing lotions, thiab cov nroj tsuag extracts, yuav pom nyob rau hauv cov khoom no.

4. Nws feem ntau yog ib qho hydrophilic thiab moisturizing muaj nyob rau hauv pleev removers. Nws cov txiaj ntsig tiag tiag yog los pab yaj cov av thiab tiv thaiv cov tawv nqaij kom qhuav sai sai thaum tshem tawm pleev. Nws kuj yog feem ntau siv nyob rau hauv lotions thiab essences.

Propylene glycol siv hauv tshuaj pleev ib ce tsis yog 100% ntxiv rau propylene glycol. Cov ntsiab lus dav dav yog li 1% txog 10%. Propylene glycol tsis yog cov khoom txwv tsis pub hauv cov tshuaj pleev ib ce, thiab nws tsis yog cov khoom txwv hauv cov tshuaj pleev ib ce.

Propylene glycol yuav luag tsis muaj xim, tsis muaj ntxhiab, tsis muaj roj, soluble hauv dej, thiab muaj cov tshuaj tua kab mob. Propylene glycol muaj zog nkag mus ua tus neeg sawv cev hauv qab thiab tuaj yeem pab lwm cov khoom xyaw sib kis thiab nkag mus rau ntawm daim tawv nqaij, tab sis thaum siv los ua tus neeg saib xyuas moisturizing, qhov feem ntawm cov dej ntes tsis siab.

Tus nqi ntawm propylene glycol ntxiv yog qhov tsis sib haum xeeb. Hauv cov tshuaj pleev ib ce, qhov kev faib ua feem ntawm propylene glycol yuav tsis pub tshaj 5%. Ob peb tus neeg yuav hnov ​​​​mob thiab kub hnyiab tom qab siv nws.

Txawm li cas los xij, nws yog qhov zoo dua kom tsis txhob siv cov khoom xyaw no rau cov tawv nqaij rhiab, thiab tsis tas yuav txhawj xeeb ntau dhau ntawm daim tawv nqaij noj qab haus huv. Propylene glycol muaj qee lub luag haujlwm hauv tshuaj pleev ib ce, yog li propylene glycol puas muaj kev phiv rau ntawm daim tawv nqaij?

Feem ntau, qhov concentration ntawm propylene glycol ntxiv hauv cov tshuaj pleev ib ce yog li 5% lossis tsawg dua, uas feem ntau tsis cuam tshuam rau daim tawv nqaij. Txawm li cas los xij, nws yog qhov yuav tsum tau ua tib zoo mloog. Yog tias nws siv sijhawm ntev thiab ntau dhau, nws yuav ua rau muaj kev puas tsuaj rau daim tawv nqaij, tshwj xeeb tshaj yog cov tawv nqaij rhiab heev. Cov kev mob tshwm sim ntawm propylene glycol ntawm daim tawv nqaij muaj xws li cov hauv qab no:

(1) Irritant: Qee tus neeg muaj kev kub nyhiab, tingling, thiab khaus thaum siv nws.

(2) Degreasing: propylene glycol muaj cov yam ntxwv ntawm cov roj-soluble hnyav, muaj zog permeability thiab siab solubility. Kev siv ntau dhau yuav ua rau muaj kev phom sij rau daim tawv nqaij. Kev siv lub sij hawm ntev ntawm qhov siab ntawm propylene glycol yuav cuam tshuam rau cov txheej txheem ntawm daim tawv nqaij thiab sebum.

(3) Irritant dermatitis: Propylene glycol yog irritating rau ntawm daim tawv nqaij thiab mucous daim nyias nyias. Qhov siab dua qhov concentration thiab qhov nruj dua, qhov ntau dua qhov khaus, uas yuav ua rau tawv nqaij liab, ua pob liab liab, tev, khaus, thiab tawv nqaij tawv. xwm txheej.
