Hydroxyethylcellulose (HEC) yakajairika mvura-inonyungudika polima inoshandiswa zvakanyanya muzvizora uye zvigadzirwa zvekuchengeta munhu. Inowanzo shandiswa seyakakora, stabilizer uye firimu rekare mune zvakasiyana siyana zvekuchengetedza ganda zvigadzirwa, shampoos, shower gels, lotions, gels uye zvimwe zvigadzirwa. Kuchengeteka kwayo kwakagamuchira kutariswa kwakapararira mumunda wekuzora.
Kemikari zvinhu uye nzira yekuita
Hydroxyethyl cellulose inogadzirwa nekurapa cellulose ne sodium hydroxide uye kuita nayo ne ethylene oxide. Cellulose inonzi polysaccharide inongowanikwa mumiti, uye kuburikidza nekuita uku, kunyungudika kwemvura kweselulosi kunowedzerwa, zvichiita kuti ive yakakodzera kushandiswa mumvura-based formulations. Hydroxyethylcellulose ine yakanaka thickening mhedzisiro, iyo inogona kuwedzera viscosity yechigadzirwa, ichiita kuti chigadzirwa chive chakapfava uye nyore kushandisa panguva yekushandiswa. Mukuwedzera, HEC inogadzirawo firimu uye inogona kuumba firimu rinodzivirira pamusoro peganda kana bvudzi kudzivirira kubuda kwemvura uye kuita basa rekunyorovesa.
Kuchengeteka kweHydroxyethyl Cellulose
Kuchengetedzwa kwehydroxyethyl cellulose kwakaongororwa nemasangano akawanda ane chiremera. Zvinoenderana nekuongororwa kweCosmetic Ingredient Review Committee (CIR) muUnited States uye European Cosmetic Regulation (EC No 1223/2009), Hydroxyethyl cellulose inoonekwa seyakachengeteka cosmetic chinhu. Mukati mehuwandu hwakatarwa hwekushandiswa kwehuwandu, HEC haikonzeri kukuvadza kune hutano hwevanhu.
Zvidzidzo zveToxicological: Zvidzidzo zvakati wandei zvakaratidza kuti Hydroxyethylcellulose haikonzere kutsamwa kweganda kana kusawirirana. Kunyange bvunzo dzehupfu kana bvunzo dzenguva refu dzehupfu dzakawana HEC kuve carcinogenic, mutagenic kana yekubereka chepfu. Nokudaro, inowanzoonekwa sechinhu chinyoro uye chisingakuvadzi cheganda nemaziso.
Kunyura kweganda: Nekuda kwehuremu hwayo hwemamorekuru, Hydroxyethylcellulose haigone kupfuura nepaburi reganda uye kupinda muhurongwa hwekutenderera kwemuviri. Kutaura zvazviri, HEC inoumba firimu rinodzivirira mushure mekushandisa, rinoramba riri pamusoro peganda risina kupinda mukati mukati meganda. Nokudaro, hazvikonzeri maitiro ekugadzirisa pamuviri wemunhu, izvo zvinowedzera kuvandudza kuchengeteka kwayo.
Kuchengeteka kwezvakatipoteredza: Hydroxyethylcellulose inoodza nharaunda uye haizokonzeresa kusvibiswa kwenguva refu kune ecosystem. Kuchengetedza kwayo kwezvakatipoteredza kwave kuchizivikanwawo nemasangano ekuchengetedza zvakatipoteredza.
Kushandiswa uye kuchengetedzwa kwekuongorora mune cosmetics
Kuwanda kwehydroxyethyl cellulose muzvizoro kunowanzo kuderera, kazhinji pakati pe0.1% ne2%. Mashandisirwo akadaro ari pasi pechikumbaridzo chayo anozivikanwa chekuchengetedza, saka zvakachengeteka zvachose kushandisa panguva idzi. Nekuda kwekugadzikana kwayo uye kugarisana kwakanaka, HEC inoshandiswa zvakanyanya mune dzakasiyana siyana zvekuzora kuwedzera magadzirirwo uye mushandisi ruzivo rwechigadzirwa.
Hydroxyethyl cellulose chinhu chinoshandiswa zvakanyanya uye chakachengeteka zvakanyanya muzvizoro. Zvingave mukushandiswa kwenguva pfupi kana kubata kwenguva refu, HEC hairatidzi chero zvingangokuvadza hutano hwevanhu. Panguva imwecheteyo, hushamwari hwayo hwezvakatipoteredza hunoitawo kuti ive yakakurumbira zvizoro zvinongedzo nhasi sezvo kusimudzira kwakasimba uye kuziva kwezvakatipoteredza kuri kuwedzera zvishoma nezvishoma. Vatengi havafanirwe kunetseka nezve kuchengetedzeka kwayo kana vachishandisa zvigadzirwa zvine hydroxyethyl cellulose, uye vanogona kunakidzwa nehunyanzvi hwekushandisa ruzivo nemhedzisiro yaunounza.
