Product Description

Nws yog tsim los ntawm cov nplai loj feem ntau rau kev tsim cov polymers. Hauv European Union, nws muaj E-tus lej E1520 rau cov ntawv thov zaub mov. Rau tshuaj pleev ib ce thiab kws tshuaj, tus naj npawb yog E490. Propylene glycol kuj muaj nyob rau hauv propylene glycol alginate, uas yog hu ua E405. Propylene glycol yog ib qho chaw sib xyaw uas yog GRAS (feem ntau lees paub tias muaj kev nyab xeeb) los ntawm US Food and Drug Administration nyob rau hauv 21 CFR x184.1666, thiab kuj tau pom zoo los ntawm FDA rau qee yam kev siv los ua khoom noj khoom haus tsis ncaj. Propylene glycol tau txais kev pom zoo thiab siv los ua lub tsheb rau tshuaj pleev, qhov ncauj, thiab qee cov tshuaj txhaj tshuaj hauv Tebchaws Meskas thiab hauv Tebchaws Europe.

Daim ntawv thov

Nws yog feem ntau siv los ua ib qho ntxiv hauv cov xim, coatings thiab adhesives los txhim kho lub gloss thiab stability ntawm txheej. Nws tseem tuaj yeem siv los ua cov kuab tshuaj thiab emulsifier hauv kev tsim cov tshuaj ntxuav, xim tshem tawm thiab dyes.

Hauv cov tshuaj formulations, MEA yog siv feem ntau rau buffering los yog npaj ntawm emulsions. MEA tuaj yeem siv los ua pH regulator hauv tshuaj pleev ib ce.

Nws yog ib qho kev txhaj tshuaj sclerosant raws li kev xaiv kho mob ntawm cov tsos mob hemorrhoids. 2-5 ml ntawm ethanolamine oleate tuaj yeem txhaj rau hauv cov mucosa saum toj no cov hemorrhoids kom ua rau mob rwj thiab mucosal fixation yog li tiv thaiv hemorrhoids los ntawm nqis tawm ntawm qhov quav.

Nws tseem yog ib qho khoom siv hauv kev ntxuav cov kua dej rau lub tsheb cua.

Qhov zoo

Lub compound yog qee zaum hu ua (alpha) α-propylene glycol kom paub qhov txawv ntawm isomer propane-1,3-diol, hu ua (beta) β-propylene glycol. Propylene glycol yog chiral. Cov txheej txheem lag luam feem ntau siv cov racemate. S-isomer yog tsim los ntawm biotechnological txoj kev.

1,2-Propanediol yog ib qho tseem ceeb raw khoom rau unsaturated polyester, epoxy resin, polyurethane resin, plasticizer, thiab surfactant. Tus nqi siv nyob rau hauv cheeb tsam no suav txog li 45% ntawm tag nrho cov kev siv ntawm propylene glycol. Nws yog dav siv nyob rau hauv cov txheej txheem saum npoo thiab cov yas reinforced. 1,2-propanediol 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. Hauv kev lag luam khoom noj khoom haus, 1,2-propanediol reacts nrog fatty acids los tsim propylene glycol fatty acid esters, uas yog siv los ua zaub mov emulsifiers; 1,2-propanediol yog ib qho hnyav heev rau seasonings thiab 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. 1,,2-Propanediol feem ntau yog siv los ua cov kuab tshuaj, softener thiab excipient nyob rau hauv kev tsim ntawm ntau yam tshuaj pleev thiab tshuaj pleev nyob rau hauv kev lag luam kws tshuaj, thiab raws li ib tug hnyav rau blending agents, preservatives, tshuaj pleev, vitamins, penicillin, thiab lwm yam nyob rau hauv cov tshuaj. kev lag luam. Vim hais tias propylene glycol muaj qhov tsis zoo nrog ntau yam txuj lom, nws kuj yog siv los ua cov kuab tshuaj thiab softener rau cov tshuaj pleev ib ce. 1,2-Propanediol kuj tseem siv los ua luam yeeb moisturizer, antifungal tus neeg sawv cev, khoom noj khoom haus lubricant thiab hnyav rau zaub mov cim inks. Aqueous daws ntawm 1,2-propanediol yog cov tshuaj tua kab mob zoo. Nws kuj yog siv los ua luam yeeb wetting tus neeg saib xyuas, tus neeg sawv cev antifungal, txiv hmab txiv ntoo ripening preservative, antifreeze thiab tshav kub cab kuj, thiab lwm yam.
