1,3-Propylene glycol an fi amfani dashi azaman sauran ƙarfi a cikin kayan kwalliya.Yana da kaushi mai laushi na polyol wanda ke taimakawa kayan kwalliya su shiga cikin fata.
Yana da mafi girma moisturizing iko fiye da glycerin, 1,2-propanediol da 1,3-butanediol.Ba shi da mannewa, ba ya jin zafi, kuma ba shi da matsalolin hangula.
Babban hanyoyin samar da 1,2-propanediol sune:
1. Hanyar hydration propylene oxide;
2. Propylene kai tsaye catalytic hadawan abu da iskar shaka hanya;
3. Hanyar musayar Ester;4.glycerol hydrolysis kira Hanyar.
1,3-Propylene glycol ana samar da shi ne ta hanyar:
1. Hanyar ruwa na Acrolein;
2. Hanyar Ethylene oxide;
3. Glycerol hydrolysis hanyar kira;
4. Hanyar microbiological.
1,3-Propylene glycol ya fi tsada fiye da 1,2-Propylene glycol.1,3-Propyleneglycol ya ɗan fi rikitarwa don samarwa kuma yana da ƙananan yawan amfanin ƙasa, don haka farashinsa har yanzu yana da girma.
Duk da haka, wasu bayanai sun nuna cewa 1,3-propanediol ba shi da fushi kuma ba shi da dadi ga fata fiye da 1,2-propanediol, har ma da kai matakin rashin jin dadi.
Saboda haka, a cikin 'yan shekarun nan, wasu masana'antun sun maye gurbin 1,2-propanediol tare da 1,3-propanediol a cikin kayan kwaskwarima don rage rashin jin daɗi da zai iya faruwa ga fata.
Rashin jin daɗin fata da kayan kwalliya ke haifarwa bazai iya haifar da 1,2-propanediol ko 1,3-propanediol kadai ba, amma kuma yana iya haifar da dalilai iri-iri.Yayin da ra'ayin mutane game da lafiyar kayan kwalliya da aminci ke zurfafa, buƙatun kasuwa mai ƙarfi zai ƙara sa masana'antun da yawa haɓaka samfuran ingantattun kayayyaki don biyan bukatun yawancin masoya kyakkyawa!
