Glycerol muaj qhov tsis sib xws ntawm lub zog moisturizing, uas tso nws nyob rau hauv pem hauv ntej hauv cosmetology. Tab sis nws muaj ntau lwm lub zog uas piav qhia nws txoj kev siv dav dav hauv lwm qhov chaw.

Glycerol feem ntau yog siv los ua moisturizer, hnyav thiab roj nplua nyeem. Lub moisturizer muaj cov cuab yeej kho dej, uas yog hais txog hydrating. Cov kuab tshuaj muaj lub zog ua kom yaj cov tshuaj. Lub lubricant yog siv los txo cov kev sib txhuam: ntawm no, qhov sib xws ntawm glycerol smoothes ntawm daim tawv nqaij, lubricates nws.

Glycerol muaj ib tug nruab nrab qab zib saj (kwv yees li 60% ntawm sucrose) thiab yog soluble ntau tshaj sorbitol, uas saj tsawg dua thiab tej zaum yuav hloov nws.

Nws yog siv rau hauv tshuaj txhuam hniav, tshuaj ntxuav qhov ncauj, moisturizers, plaub hau khoom, thiab xab npum. Nws kuj yog ib feem ntawm glycerin soaps, tshwj xeeb yog Marseille soaps.

Glycerin hauv cov ntsiab lus muaj ntau yam khoom:

• Nws muab smoothness rau ntau yam khoom;
• Nws muaj zog hydrating zog ua tsaug rau nws lub peev xwm khaws tau ob peb zaug nws qhov hnyav hauv dej. Yog li, nws tsim ib qho kev thaiv ntawm cov epidermis, txwv tsis pub ya raws thaum rov ua haujlwm ntawm lipids uas ua lub luag haujlwm tseem ceeb hauv kev kho daim tawv nqaij;
• Nws muaj emollient zog. Lo lus emollient hauv tshuaj txhais tau tias: uas so cov ntaub so ntswg (los ntawm Latin mollire, soften). Figuratively, softening, mos. Uas yog hais, nws smooths daim tawv nqaij thiab plaub hau thaum tuav ib tug zoo theem ntawm hydration;
• Nws muaj nuj nqi occlusive tso cai rau cov tawv nqaij tiv thaiv los ntawm sab nraud aggressions xws li cua thiab pa phem;
• Hauv kev xyaum, nws yog siv ib zaug lossis ob zaug hauv ib hnub, hauv txheej nyias.

Cov ntaub ntawv pov thawj zoo tshaj plaws ntawm nws lub zog moisturizing yog nws siv hauv kev kho mob dermatology los daws lossis txawm kho cov kab mob tsis zoo los yog kev mob tshwm sim.

• Los ntawm txoj kev cutaneous, ua ke nrog paraffin thiab roj av jelly, glycerol yog siv nyob rau hauv kev tswj ntawm burns, atopic dermatitis, ichthyosis, psoriasis, daim tawv nqaij dryness;
• Los ntawm txoj kev cutaneous, ua ke nrog talc thiab zinc, glycerol yog siv los tswj cov kab mob dermatitis thiab pob khaus, tshwj xeeb hauv cov menyuam mos.

Yog li ntawd, glycerol los yog glycerin yog ib qho tsis muaj xim, tsis muaj ntxhiab, viscous kua nrog qab zib. Nws cov molecule muaj 3 pawg hydroxyl sib thooj rau 3 lub luag haujlwm ntawm cawv ua lub luag haujlwm rau nws cov solubility hauv dej thiab nws qhov hygroscopic xwm.

Cov tshuaj hygroscopic yog ib yam khoom uas nyiam khaws cov dej noo los ntawm kev nqus los yog adsorption. Tsis tas li ntawd, glycerol khaws cia tsis zoo thiab dilutes los ntawm absorbing noo noo los ntawm huab cua.

Cov khoom uas pom nyob rau hauv lub khw muaj xws li ntshiab glycerol los yog sib tov raws li glycerol. Kev sib xyaw ua ke ntawm glycerol + roj av jelly + paraffin yog qhov nthuav tshwj xeeb. Ib qho kev tiv thaiv ntawm daim tawv nqaij kuj tau pom los ntawm ex vivo kev ntsuam xyuas tau ua los ntawm cov ntaub so ntswg delipidated, uas yog hais tias tsis muaj lipids (tsis muaj rog).

Cov kev ntsuam xyuas no tau pom qhov kev hloov kho sai ntawm lipid barrier nrog kev ua qauv qhia ntawm kev ua haujlwm emollient ntawm Glycerol / Vaseline / Paraffin ua ke. Cov khoom no, tau pom nyob rau hauv pharmaco-kev soj ntsuam cov kev tshawb fawb ntawm cov qauv siv tau, txhawb kev kho cov dej hauv xeev thiab kev ua haujlwm ntawm daim tawv nqaij, uas yuav txo tau qhov tshwm sim ntawm khaus, khaus thiab khawb. Nco tseg: kev sib xyaw ua ke no yuav tsum tsis txhob siv rau ntawm daim tawv nqaij muaj kab mob, los yog hnav khaub ncaws occlusive, uas yog hais txog kev hnav khaub ncaws kaw.

Peb pom lo lus glycerol hauv triglycerides, feem ntau ntsuas hauv cov ntshav thaum peb thov kom muaj daim ntawv tshuav nyiaj li cas txawm tias basal. Tseeb, nws yog nyob rau hauv nruab nrab ntawm tag nrho cov lipids (rog) nyob rau hauv lub cev. Nws yog lub zog ntawm lub zog: sai li sai tau thaum lub cev xav tau lub zog, nws rub glycerol los ntawm cov khw muag roj thiab dhau mus rau hauv cov ntshav.

Muaj peb qhov chaw tsim khoom glycerol:

• Saponification: yog tias cov dej qab zib ntxiv rau cov roj lossis tsiaj lossis zaub rog, tau txais ib qho xab npum thiab glycerol. Glycerol yog cov khoom siv los ntawm kev ua xab npum;
• Cov cawv fermentation ntawm txiv hmab txiv ntoo yuav tsum thaum lub sij hawm tsim cawv;
• Lub transesterification ntawm zaub roj, uas nyob rau hauv luv luv tshwm sim nyob rau hauv biodiesel (roj). Ib zaug ntxiv, glycerol yog cov khoom siv los ntawm kev ua haujlwm no.

Peb twb pom tias glycerol nkag mus rau hauv cov khoom ntawm ntau cov tshuaj dermatological. Tab sis nws kuj muaj nyob rau hauv cov tshuaj (qab zib hwj chim ntawm syrups), suppositories, soaps, tshuaj txhuam hniav. Nws yog ib qho qab ntxiag hloov rau sorbitol (vim nws qab qab zoo dua). Nws muaj ib tug laxative zog yog absorbed nyob rau hauv txaus kom muaj nuj nqis thiab yog weakly diuretic.

Thiab ntawm chav kawm, nws muaj nyob rau hauv cov zaub mov: nws yog cov additive E422 uas stabilizes, softens thiab thickens tej yam khoom noj. Yog tias peb ntxiv tias peb tuaj yeem ua rau hauv tsev thiab nws kuj muaj kev siv hauv tsev, peb tsis nyob deb ntawm kev ua nws lub panacea.
