Propylene Glycol chinhu chaunowanzoona mune zvinongedzo zvemazwi ezvizoro zvemazuva ese kushandiswa. Vamwe vanonzi vakanyorwa 1,2-procandiol uye vamwe se1,3-procandioliol, Saka mutsauko chii?
1,2-procylene glycol, Casha Nha. 57-55-6, Molecular Formula C3H8O2, inoshandisirwa nemvura, ethanol nemvura uye yakawanda organic sol sol. Iyo isina ruvara viscous yemvura mune yakajairika nyika, zvounenge zvisina kufanira uye zvishoma zvinotapira pane zvakanaka kunhuhwirira.
Inogona kushandiswa seynonetting mumiririri mune cosmetics, mazino uye sipo pamwe ne glycerin kana sorbitol. Iyo inoshandiswa seyakajaira uye yakawedzera mumiririri mubvudzi rebvudzi uye seAntiFreeze mumiririri.
1,3-PropertyneGlycol, Cas No. 504-63-2, Molecular Forpula, isingaoneki, ine munyu, hyglfied, inokatyamadzwa nemvura, isinganzwisisike mu ethanol, ether.
Inogona kushandiswa mune synthesis yemhando dzakawanda dzemishonga, nyowani polyester ptt, pharmaceutical yepakati uye itsva antioxidants. Icho chinhu chakabikwa chekugadzirwa kwePolyester polyester, plasticisazer, surasantant, emulsifioni uye emulsion breker.
Ose ari maviri ane zvakafanana molecular formula uye isoomers.
1,2-procylene glycol inoshandiswa seye antibacterial mumiririri kana muputi wemugodhi mune zesetics pakukwirira kwakanyanya.
Pazasi pakadzika, inowanzoshandiswa seye moisturizer kana kuchenesa rubatsiro.
Pakukadzika nzvimbo, inogona kushandiswa sepa-solvent yeanoshanda zvinoshanda.
Iko kushatirwa kweganda uye kuchengetedzwa pane dzakasiyana kutarisisa kwakasiyana zvachose.
1,3-procylene glycol inonyanya kushandiswa sechigadzika mune cosmetics. Iyo organic polyol moisturizing solvent inobatsira macommetic zvimedu zvinopinda muganda.
Iyo ine yakakwira simba rekunyanyisa kupfuura glycerin, 1,2-praneddiol uye 1,3-butanedoliol. Izvo hazvina kunamatira, hapana kunzwa kunopisa, uye hapana matambudziko ekutsamwisa.
Nzira huru yekugadzira ye1,2-procandiol ndeye:
1. Propyleo oxide hydration nzira;
2. Profyle yakananga catalytic oxidation nzira;
3. Ester exchange nzira; 4.Gycrol hydrolysis synthesis nzira.
1,3-profyle glycol inonyanya kugadzirwa ne:
1. Acrolein Mhedzisiro nzira;
2 .: Ethylene oxide nzira;
3. Glycerol hydrolysis synthesis nzira;
4. Microbiological nzira.
1,3-procylene glycol inodhura kupfuura 1,2-profyley glycol.1,3-PropertyneGlycol ishoma zvishoma kuomarara kugadzira uye ine gohwo rakaderera, saka mutengo wazvo uchiri kumusoro.
Nekudaro, rumwe ruzivo runoratidza kuti 1,3-procaneddiol hadzina kutsamwiswa neganda kupfuura 1,2-procaneddiol, kunyangwe kusvika padanho rekusazvibata.
Naizvozvo, mumakore achangopfuura, vamwe vagadziri vakatsiva 1,2-procanedurers vane 1,3-procandeoliol mune cosmetic zvimisikidzwa kuti vaderedze kusagadzikana uko kunogona kuitika kuganda.
Kusagadzikana kweganda kunokonzerwa nemazwi kunogona kunge kusiri kukonzerwa ne 1,2 prananiol kana 1,3-praridedioli yega, asi inogona zvakare kuve yakakonzerwa nezvinhu zvakasiyana siyana. Semunhu evanhu emhando yehutano hwehukama uye kuchengeteka kwakasimba, iyo yakasimba yemusika inodiwa ichawedzera kukurudzira vakawanda vagadziri kukudziridza zvigadzirwa zviri nani kuti vazivane nezvakawanda zvevanoda runako!
