Bambanci tsakanin 1,2-propanediol da 1,3-propanediol a cikin kayan kwalliya

Propylene glycol wani sinadari ne da ake yawan gani a cikin jerin sinadaran kayan kwalliya na amfanin yau da kullun. Wasu ana yiwa lakabi da 1,2-propanediol wasu kuma ana kiransu da 1,2-propanediol1,3-propanediol, to menene bambanci?
1,2-Propylene glycol, CAS No. 57-55-6, dabarar kwayoyin halitta C3H8O2, wani sinadari ne mai sinadarai, wanda ake iya haɗawa da ruwa, ethanol da sauran sinadarai masu yawa na halitta. Ruwa ne mai ƙamshi mara launi a yanayin da ya dace, kusan babu ƙamshi kuma ɗan daɗi idan aka yi amfani da shi da ƙamshi mai kyau.
Ana iya amfani da shi a matsayin maganin jika a kayan kwalliya, man goge baki da sabulu tare da glycerin ko sorbitol. Ana amfani da shi a matsayin maganin jika da daidaita rini a cikin gashi da kuma maganin hana daskarewa.
1,3-Propyleneglycol, CAS No. 504-63-2, dabarar kwayoyin halitta ita ce C3H8O2, ruwa ne mai kauri mara launi, mara wari, mai gishiri, mai tsafta, ana iya shafawa, a tace shi, a juya shi da ruwa, a juya shi a cikin ethanol, da ether.
Ana iya amfani da shi wajen haɗa nau'ikan magunguna da yawa, sabbin PTT na polyester, magungunan tsakiya da sabbin antioxidants. Ita ce kayan da ake amfani da su wajen samar da polyester mara cika, plasticizer, surfactant, emulsifier da emulsion breaker.
Dukansu suna da tsari iri ɗaya na kwayoyin halitta kuma sune isomers.
Ana amfani da 1,2-Propylene glycol a matsayin maganin kashe ƙwayoyin cuta ko kuma mai haɓaka shigar ƙwayoyin cuta a cikin kayan kwalliya a cikin adadi mai yawa.
A ƙananan yawan da ake samu, galibi ana amfani da shi azaman moisturizer ko taimakon tsarkakewa.
A ƙananan yawan abubuwa, ana iya amfani da shi azaman maganin hana narkewar abubuwa masu aiki.
Ƙaiƙayin fata da amincinsa a wurare daban-daban sun bambanta sosai.
Ana amfani da 1,3-Propylene glycol a matsayin mai narkewa a kayan kwalliya. Yana da sinadarin da ke sanya sinadarin polyol ya shiga fata.
Yana da ƙarfi mai ƙarfi fiye da glycerin, 1,2-propanediol da 1,3-butanediol. Ba shi da mannewa, babu ƙonewa, kuma babu matsalolin ƙaiƙayi.
Manyan hanyoyin samar da 1,2-propanediol sune:
1. Hanyar haƙar propylene oxide;
2. Hanyar hada iskar shaka ta propylene kai tsaye;
3. Hanyar musayar ester; 4. hanyar haɗa sinadarin glycerol hydrolysis.
1,3-Propylene glycol galibi ana samar da shi ta hanyar:
1. Hanyar ruwa ta Acrolein;
2. Hanyar ethylene oxide;
3. Hanyar haɗa sinadarin glycerol hydrolysis;
4. Hanyar ƙwayoyin cuta.
1,3-Propylene glycol ya fi tsada fiye da 1,2-Propylene glycol.1,3-PropyleneGlycol yana da ɗan rikitarwa wajen samarwa kuma yana da ƙarancin yawan amfanin ƙasa, don haka farashinsa har yanzu yana da tsada.
Duk da haka, wasu bayanai sun nuna cewa 1,3-propanediol ba shi da zafi sosai kuma ba shi da daɗi ga fata fiye da 1,2-propanediol, har ma ya kai matakin rashin jin daɗi.
Saboda haka, a cikin 'yan shekarun nan, wasu masana'antun sun maye gurbin 1,2-propanediol da 1,3-propanediol a cikin kayan kwalliya don rage rashin jin daɗin da zai iya faruwa ga fata.
Rashin jin daɗin fata da kayan kwalliya ke haifarwa ba zai iya faruwa ba ta hanyar 1,2-propanediol ko 1,3-propanediol kaɗai, amma kuma yana iya faruwa ne ta hanyoyi daban-daban. Yayin da ra'ayin mutane game da lafiyar kwalliya da aminci ke ƙaruwa, buƙatar kasuwa mai ƙarfi za ta ƙara tura masana'antun da yawa su ƙirƙiro ingantattun kayayyaki don biyan buƙatun yawancin masoyan kwalliya!
