Hydroxyethylcellulose (HEC) ke polima e tloaelehileng e qhibilihang ka metsing e sebelisoang haholo ho litlolo le lihlahisoa tsa tlhokomelo ea motho. Hangata e sebelisoa e le motenya, stabilizer le filimi ea pele lihlahisoa tse fapaneng tsa tlhokomelo ea letlalo, li-shampoo, li-gels tsa shaoara, litlolo, li-gel le lihlahisoa tse ling. Tšireletseho ea eona e fumane tlhokomelo e pharaletseng lefapheng la litlolo.
Lintho tsa lik'hemik'hale le mokhoa oa ho sebetsa
Hydroxyethyl cellulose e entsoe ka ho phekola selulose ka sodium hydroxide le ho e arabela ka ethylene oxide. Cellulose ke polysaccharide ka tlhaho e fumanoang limela, 'me ka ts'ebetso ena, ho qhibiliha ha metsi ka selulose hoa ntlafatsoa, ho etsa hore e loketse ho sebelisoa mefuteng ea metsi. Hydroxyethylcellulose e na le phello e ntle ea thickening, e ka eketsang viscosity ea sehlahisoa, ho etsa hore sehlahisoa se be bonolo 'me se be bonolo ho se sebelisa nakong ea tšebeliso. Ho phaella moo, HEC e boetse e etsa filimi 'me e ka etsa filimi e sireletsang holim'a letlalo kapa moriri ho thibela ho fetoha mouoane oa metsi le ho bapala karolo ea mongobo.
Tšireletseho ea Hydroxyethyl Cellulose
Tšireletseho ea hydroxyethyl cellulose e hlahlobiloe ke mekhatlo e mengata e nang le bolaoli. Ho ea ka tlhahlobo ea Cosmetic Ingredient Review Committee (CIR) United States le European Cosmetic Regulation (EC No 1223/2009), Hydroxyethylcellulose e nkoa e le motsoako o sireletsehileng oa litlolo. Ka har'a mefuta e mengata e behiloeng ea tšebeliso, HEC ha e bake kotsi bophelong ba batho.
Lithuto tsa Toxicological: Lithuto tse 'maloa tsa toxicological li bonts'itse hore Hydroxyethylcellulose ha e bake ho teneha ha letlalo kapa ho hana ho hana. Ha ho liteko tse matla tsa chefo kapa liteko tsa nako e telele tsa chefo tse fumaneng HEC e le chefo ea kankere, ea mutagenic kapa ea ho ikatisa. Ka hona, e nkoa e le motsoako o bonolo le o se nang kotsi bakeng sa letlalo le mahlo.
Ho monya ha letlalo: Ka lebaka la boima ba eona bo boholo ba limolek'hule, Hydroxyethylcellulose ha e khone ho feta mokoallong oa letlalo ebe e kena tsamaisong ea 'mele. Ha e le hantle, HEC e etsa filimi e sireletsang ka mor'a hore e sebelisoe, e setseng holim'a letlalo ntle le ho kenella ka hare ho letlalo. Ka hona, ha e bake liphello tsa tsamaiso 'meleng oa motho, e leng ho ntlafatsang polokeho ea eona le ho feta.
Polokeho ea tikoloho: Hydroxyethylcellulose e ka bola tikolohong 'me e ke ke ea baka tšilafalo ea nako e telele tikolohong ea tikoloho. Tšireletseho ea eona ea tikoloho e boetse e hlokomeloa ke mekhatlo e sireletsang tikoloho.
Tlhahlobo ea kopo le polokeho ho litlolo
Bongata ba hydroxyethyl cellulose litlolo hangata bo tlase, hangata bo pakeng tsa 0.1% le 2%. Maemo a joalo a ts'ebeliso a ka tlase ho moeli oa eona o tsebahalang oa polokeho, ka hona ho bolokehile ho sebelisoa maemong ana. Ka lebaka la botsitso le tumellano e ntle, HEC e sebelisoa haholo litlolong tse fapaneng ho ntlafatsa sebopeho le boiphihlelo ba mosebelisi ba sehlahisoa.
Hydroxyethyl cellulose ke motsoako o sebelisoang haholo le o bolokehileng haholo litlolong. Ho sa tsotellehe hore na ke tšebeliso ea nako e khutšoanyane kapa ea nako e telele, HEC ha e bontše kotsi leha e le efe e ka bang kotsi bophelong ba batho. Ka nako e ts'oanang, botsoalle ba eona ba tikoloho le bona bo etsa hore e be motsoako o tsebahalang oa litlolo kajeno ha nts'etsopele e tsitsitseng le tlhokomeliso ea tikoloho e ntse e eketseha butle-butle. Bareki ha ba hloke ho tšoenyeha ka polokeho ea eona ha ba sebelisa lihlahisoa tse nang le hydroxyethyl cellulose, 'me ba ka thabela boiphihlelo bo botle ba tšebeliso le litlamorao tseo e li tlisang.
