Sorbitol e sebelisoa e le motsoako, moisturizer, antifreeze ka sesepa sa meno, e phaella ho 25 ~ 30%, e ka bolokang pente e tlotsitse, 'mala le tatso e ntle;E le moemeli o thibelang ho omisa ka litlolo (ho e-na le glycerin), e ka ntlafatsa ho atolosa le lubricity ea emulsifier 'me e loketse ho boloka nako e telele;Sorbitan fatty acid ester le ethylene oxide adduct ea eona e na le monyetla oa ho teneha ho fokolang letlalong mme e sebelisoa haholo indastering ea litlolo.
Sorbitol ke sehlahisoa se sebelisoang haholo sa lik'hemik'hale.Sorbitol e felloa ke metsi, e entsoe ka hydrolysed, e esterified, e koaletsoe ka aldehydes, e sebetsa ka epoxides, 'me e entsoe ka polymerization ea monoma kapa polymerization e entsoeng ka mefuta e fapaneng ea li-monomers ho theha letoto la lihlahisoa tse ncha tse nang le thepa e ntle haholo le mesebetsi e ikhethang.Sorbitan fatty acid ester le ethylene oxide adduct ea eona e na le monyetla oa ho teneha ho fokolang letlalong mme e sebelisoa haholo indastering ea litlolo.
Sorbitol le propylene oxide li sebelisoa ho hlahisa foam e thata ea polyurethane e nang le thepa e thibelang malakabe, kapa ka mafura a maiketsetso a lipids ho hlahisa lipente tsa oli ea alkyd resin.Sorbitol rosin hangata e sebelisoa e le thepa e tala bakeng sa liphahlo tsa meralo.Sorbitan grease e sebelisoa e le plasticizer le lubricant ka polyvinyl chloride resin le polymers tse ling, hape e ka sebelisoa e le polasetiki bakeng sa liphahlo tsa meralo, litlolo le lisebelisoa tse fokotsang metsi ka konkreite.
Sorbitol e entsoe ka li-ion tsa tšepe, koporo le aluminium ka tharollo ea alkaline 'me e sebelisoa ho soeufatsa le ho hlatsoa indastering ea masela.
Keketso ea lijo
Ha lihlopha tsa hydroxyl li na le tsoekere e ngata, li na le phello e ntle ea ho thibela protheine e hatsetsang denaturation.Sorbitol e na le lihlopha tse 6 tsa hydroxyl, tse nang le metsi a matla a ho monya metsi 'me li ka kopanngoa le metsi ka hydrogen bonding ho fokotsa mosebetsi oa metsi oa sehlahisoa le ho boloka tatso le boleng ba sehlahisoa.
Ka ho kopanya ka matla le metsi, sorbitol e ka fokotsa ts'ebetso ea metsi ea sehlahisoa, ka hona e fokotsa kholo le ho ikatisa ha likokoana-hloko.Sorbitol e na le thepa ea chelating 'me e ka tlama li-ion tsa tšepe ho etsa li-chelates, kahoo e boloka metsi a ka hare le ho thibela li-ion tsa tšepe hore li se ke tsa tlama ts'ebetso ea enzyme, ho fokotsa mosebetsi oa li-protease.Bakeng sa polokelo ea leqhoa, sorbitol e le moemeli oa antifreeze e ka fokotsa ho thehoa ha likristale tsa leqhoa, ea sireletsa botšepehi ba lisele le ho thibela ho senyeha ha liprotheine, 'me li-preservatives tse ling tse kang phosphate e rarahaneng li ka ntlafatsa phello ea antifreeze.Ha ho etsoa lihlahisoa tsa metsing, sorbitol e boetse e sebelisoa haholo e le mokhoa oa ho fokotsa ts'ebetso ea metsi ho ntlafatsa bophelo ba polokelo le boleng ba lihlahisoa.Motsoako oa sehlopha sa moemeli oa antifreeze (1% motsoako oa phosphate + 6% trehalose + 6% sorbetol) o ntlafalitse haholo matla a tlamang a li-shrimp le metsi, 'me a thibela tšenyo ea likristale tsa leqhoa ho mesifa ea mesifa nakong ea ts'ebetso ea ho qhibiliha ha leqhoa.Motsoako oa L-lysine, sorbitol le sodium substitute matsoai a tlaase (20% potassium lactate, 10% calcium ascorbate le 10% magnesium chloride) e ka ntlafatsa boleng ba nama ea khomo e lokisitsoeng ka letsoai le tlaase la sodium.
