Iyini iHydroxyethyl Cellulose?

I-Hydroxyethyl cellulose iyi-fibrous emhlophe kuya kokuphuzi ngokukhanyayo noma eyimpuphu eqinile, engenabuthi, ayinambitheki, futhi inyibilika kalula emanzini. Ayincibiliki kuma-organic solvents. Inezici zokujiya, ukumisa okwesikhashana, ukubopha, i-emulsifying, ukuhlakaza, nokugcina umswakama. Izixazululo ezinobubanzi obuhlukahlukene be-viscosity zingalungiswa. Inoncibilika kahle kasawoti kuma-electrolyte. I-Hydroxyethyl cellulose iyimpushana emhlophe noma ekhanyayo engenaphunga, ayinambitheki, futhi egeleza kalula. Iyancibilika kuwo womabili amanzi abandayo nashisayo, futhi ngokuvamile ayincibiliki kuzincibilikisi eziningi eziphilayo. I-viscosity ishintsha kancane uma inani le-pH likububanzi obungu-2-12, kodwa i-viscosity yehla ngale kwalolu bubanzi.

Isicelo

1. I-Hydroxyethyl cellulose (HEC) iyi-ether ye-cellulose e-non-ionic encibilikayo enokuqina okuhle, ukumiswa, ukusabalalisa, i-emulsification, ukunamathela, ukwakheka kwefilimu, ukuvikelwa komswakama kanye nezakhiwo ze-colloid ezivikelayo. Ngenxa yezakhiwo zayo eziyingqayizivele zomzimba namakhemikhali, i-HEC isetshenziswa kabanzi emikhakheni eminingi, kufaka phakathi kodwa ingagcini nje ekukhishweni kwamafutha, ukumbozwa, ukwakhiwa, ukudla okwenziwa imithi, izindwangu, ukwenza amaphepha kanye ne-polymerization.
2. Emkhakheni wemithi, ngaphezu kokuba i-thickener ne-ejenti evikelayo, i-hydroxyethyl cellulose nayo inemiphumela yokuthambisa, ukukhipha amanzi, ukulwa nokuguga, ukuhlanza isikhumba, nokukhipha i-melanin. Ilungele ukwenza amaconsi esweni, izifutho zekhala, izixazululo zomlomo, njll. Ingakhuphula i-viscosity yomuthi, ithuthukise izinga lokumuncwa kwesidakamizwa emzimbeni, futhi yandise ukuzinza kwesidakamizwa ukuvimbela ukubola kwezidakamizwa kanye ne-oxidation.
3. Embonini yezimonyo, i-HEC isetshenziswa kakhulu ekwenzeni i-shampoo, i-conditioner, ukhilimu, amafutha okugcoba neminye imikhiqizo. Ingakwazi ukulungisa i-viscosity nokuthungwa kwezimonyo ukuze izenze zibe lula ukuzisebenzisa futhi zimunce. Ngesikhathi esifanayo, ibuye ibe nomphumela wokuthambisa, ingavala umswakama, futhi ivimbele ukoma kwesikhumba nokuqhekeka.
4. Ngaphezu kwalokho, i-hydroxyethyl cellulose isetshenziswa ikakhulukazi njenge-thickener, colorant kanye ne-preservative embonini yokudla, engakhuphula i-viscosity nokuthungwa kokudla futhi ithuthukise ukunambitheka kanye nekhwalithi yokudla. Ingasetshenziswa futhi njenge-emulsifier ne-stabilizer ukuvimbela ukuhlukaniswa kokudla kanye nemvula.
5. Mayelana ne-acidity ne-alkalinity ye-hydroxyethyl cellulose, njengoba ingeyesigaba se-non-ionic cellulose ether, ayinayo i-asidi noma i-alkaline. Ifomula yayo yamakhemikhali ithi (C2H6O2)n, enezimfanelo ezinhle zokuncibilika, ukuzinza kanye nokujiya, futhi idlala indima ebalulekile emikhakheni ehlukahlukene yesicelo.
