Propylene glycol yog cov organic compound nrog cov tshuaj formula C3H8O2, uas yog miscible nrog dej, ethanol thiab ntau yam organic solvents.Propylene glycol yog cov kua uas tsis muaj xim tsis muaj xim nyob rau hauv ib txwm muaj, yuav luag tsis muaj ntxhiab thiab qab zib me ntsis.Qhov hnyav molecular yog 76.09.
Propylene Glycol Properties thiab Stability
1. Flammable kua.Nws yog hygroscopic thiab tsis corrode hlau.
2. Toxicity thiab khaus khaus me me heev.
3. Muaj nyob rau hauv cov nplooj thiab cov pa luam yeeb.
Kev siv propylene glycol
Propylene glycol tuaj yeem siv ua cov tshuaj humectant ua ke nrog glycerin lossis sorbitol hauv tshuaj pleev ib ce, tshuaj txhuam hniav thiab xab npum.Nyob rau hauv cov plaub hau dyes, nws yog siv raws li ib tug moisturizing thiab leveling tus neeg saib xyuas, raws li ib tug antifreeze, raws li zoo raws li nyob rau hauv cellophane, plasticizer thiab tshuaj industr.
(1) Propylene glycol yog ib qho tseem ceeb raw khoom rau unsaturated polyesters, epoxy resins, polyurethane resins, plasticizers, thiab surfactants, thiab cov nyiaj siv nyob rau hauv no hais txog suav txog li 45% ntawm tag nrho cov noj ntawm propylene glycol.Rau cov txheej txheem saum npoo thiab cov yas muaj zog.
(2) Propylene glycol muaj viscosity zoo thiab hygroscopicity, thiab yog dav siv los ua hygroscopic agent, antifreeze agent, lubricant thiab hnyav nyob rau hauv cov zaub mov, tshuaj thiab tshuaj pleev ib ce industries.
(3) Hauv kev lag luam khoom noj khoom haus, propylene glycol reacts nrog fatty acids los tsim propylene glycol fatty acid esters, uas yog siv los ua zaub mov emulsifiers;propylene glycol yog cov kuab tshuaj zoo heev rau cov khoom noj thiab cov pigments.Vim nws tsis tshua muaj toxicity, nws yog siv los ua ib qho hnyav rau cov txuj lom thiab zaub mov xim hauv kev lag luam khoom noj.
(4) Propylene glycol feem ntau yog siv rau hauv kev lag luam kws tshuaj raws li cov kuab tshuaj, softener thiab excipient rau kev tsim khoom ntawm ntau yam tshuaj pleev, thiab raws li ib tug hnyav rau blending agents, preservatives, ointments, vitamins, penicillin, thiab lwm yam nyob rau hauv kev lag luam kws tshuaj.
(5) Vim hais tias propylene glycol muaj kev sib nrig sib solubility nrog ntau yam fragrances, nws kuj yog siv los ua ib qho hnyav thiab softener rau tshuaj pleev ib ce, thiab lwm yam.
(6) Propylene glycol kuj yog siv los ua luam yeeb moisturizing tus neeg saib xyuas, mildew inhibitor, lubricating roj rau cov khoom ua zaub mov thiab hnyav rau zaub mov cim.
(7) Aqueous daws ntawm propylene glycol yog cov tshuaj tua kab mob zoo.Kuj tseem siv los ua tus neeg haus luam yeeb wetting, mildew inhibitor, txiv hmab txiv ntoo ripening preservative, antifreeze thiab tshav kub cab kuj, thiab lwm yam.
