Nhanganyaya yeHydroxyethylcellulose (HEC)
Hydroxyethylcellulose ikemikari yakagadziridzwa cellulose polymer inotorwa kubva muselulosi kuburikidza nemaitiro etherification.Inowanzoshandiswa mumaindasitiri akasiyana siyana, anosanganisira emishonga, zvekuzora, uye zvekudya.Mune maindasitiri aya, HEC inoshanda zvakanyanya seyakakora, gelling, uye inodzikamisa mumiriri nekuda kweiyo yakasarudzika midziyo, sekuchengetedza mvura uye kugona kugadzira firimu.
Kazhinji Kushandiswa kweHydroxyethylcellulose
Cosmetics: HEC chinhu chakajairika muzvizoro uye zvigadzirwa zvekuchengeta zvemunhu zvakaita seshamposi, maconditioner, makirimu, lotions, uye gels.Inobatsira kuvandudza magadzirirwo, viscosity, uye kugadzikana kwezviumbwa izvi.
Pharmaceuticals: Mukugadzirwa kwemishonga, HEC inoshandiswa seyakakora uye inomisa mumiriri mune yemvura dosage mafomu senge masirapi, kumiswa, uye gels.
Indasitiri yeChikafu: HEC inoshandiswa muindasitiri yechikafu seyakakora uye inodzikamisa mumiriri mune dzakasiyana siyana zvigadzirwa zvechikafu senge sosi, madhirezi, uye madhiri.
Allergic Reactions kune Hydroxyethylcellulose
Allergic reactions kune HEC haiwanzo asi inogona kuitika kune vanhu vanotapukirwa.Aya maitiro anogona kuratidzwa nenzira dzakasiyana, kusanganisira:
Kushatirwa kweGanda: Zviratidzo zvinogona kusanganisira kutsvuka, kukwenya, kuzvimba, kana kuputika panzvimbo yekubata.Vanhu vane ganda rinopfava vanogona kuona zviratidzo izvi pavanenge vachishandisa zvizorwa kana zvigadzirwa zvekuchengeta munhu zvine HEC.
Zviratidzo zvekufema: Kufemba HEC zvimedu, kunyanya munzvimbo dzebasa senge zvivakwa zvekugadzira, zvinogona kutungamira kune zviratidzo zvekufema senge kukosora, kufema, kana kupfupika kwekufema.
Gastrointestinal Distress: Kunwa kweHEC, kunyanya muhuwandu hukuru kana kune vanhu vane mamiriro ekutanga emimba, zvinogona kukonzera zviratidzo zvakadai sekunyunyuta, kurutsa, kana manyoka.
Anaphylaxis: Muzviitiko zvakakomba, kusawirirana kweHEC kunogona kukonzera anaphylaxis, mamiriro ezvinhu anotyisa ehupenyu anoratidzwa nekudonha kamwe kamwe muropa, kunetseka kufema, uye kurasikirwa kwekuziva.
Kuongororwa kweHydroxyethylcellulose Allergy
Kuongorora allergy kuHEC kunowanzobatanidza musanganiswa wenhoroondo yekurapa, kuongororwa kwemuviri, uye kuongororwa kweallergy.Matanho anotevera anogona kutorwa:
Nhoroondo Yezvokurapa: Mupi wehutano anozobvunza nezve zviratidzo, zvinogona kuitika kune HEC-ine zvigadzirwa, uye chero nhoroondo yeallergies kana allergic reactions.
Kuongororwa Kwenyama: Kuongororwa kwemuviri kunogona kuratidza zviratidzo zvekutsvuka kweganda kana kumwe kusawirirana.
Patch Testing: Kuongororwa kwechigamba kunosanganisira kushandisa zvidiki zvidiki zvemagetsi, kusanganisira HEC, paganda kuti utarise chero maitiro.Uyu muedzo unobatsira kuziva allergic contact dermatitis.
Skin Prick Test: Muyedzo yeganda prick, shoma shoma yeallergen extract inobaiwa muganda, kazhinji paruoko kana kumashure.Kana munhu ari allergic kune HEC, vanogona kukudziridza maitiro emunharaunda panzvimbo yepick mukati me15-20 maminetsi.
Ropa Rokuongorora: Kuongororwa kweropa, kwakadai sekuongororwa kweIgE (immunoglobulin E) chaiyo, inogona kuyera kuvapo kweHEC-specific antibodies muropa, zvichiratidza mhinduro yeallergic.
Matanho Ekutungamira eHydroxyethylcellulose Allergy
Kugadzirisa allergy kuHEC kunosanganisira kudzivirira kuratidzwa kune zvigadzirwa zvine chinhu ichi uye kushandisa nzira dzakakodzera dzekurapa kune allergic reaction.Heano mamwe maitiro:
Kudzivisa: Ziva uye dzivirira zvigadzirwa zvine HEC.Izvi zvinogona kusanganisira kunyatsoverenga zvinyorwa zvechigadzirwa uye kusarudza zvimwe zvigadzirwa zvisina HEC kana zvimwe zvine chekuita nazvo.
Kutsiva: Tsvaga zvimwe zvigadzirwa zvinoshanda zvakafanana asi zvisina HEC.Vazhinji vagadziri vanopa HEC-yemahara magadzirirwo ezvizoro, zvigadzirwa zvekuchengeta munhu, uye mishonga.
Symptomatic Treatment: Mishonga ye-over-the-counter yakadai se antihistamines (semuenzaniso, cetirizine, loratadine) inogona kubatsira kubvisa zviratidzo zvekusagadzikana, zvakadai sekucheka uye kuputika.Topical corticosteroids inogona kurongerwa kuderedza kuzvimba kweganda uye kutsamwa.
Emergency Preparedness: Vanhu vane nhoroondo yekusagadzikana kwakanyanya, kusanganisira anaphylaxis, vanofanira kutakura epinephrine auto-injector (eg, EpiPen) nguva dzose uye vanoziva mashandisirwo ayo kana pane dambudziko.
Kuonana neVanopa Vehutano: Kurukura chero zvinonetsa kana mibvunzo pamusoro pekutonga HEC allergy nevashandi vehutano, kusanganisira allergists uye dermatologists, vanogona kupa hutungamiriri hwemunhu uye kurudziro yekurapa.
Nepo hydroxyethylcellulose iri chinhu chinoshandiswa zvakanyanya muzvigadzirwa zvakasiyana, kusawirirana kune iyi komputa kunogoneka, kunyangwe zvisingaite.Kuziva zviratidzo nezviratidzo zveHEC allergy, kutsvaga kuongororwa kwakakodzera kwekurapa uye kuongororwa, uye kushandisa nzira dzekutonga dzinoshanda matanho akakosha kune vanhu vanofungidzirwa kuti vane allergy iyi.Nekunzwisisa njodzi dzinogona kuitika dzine chekuita nekufumurwa kweHEC uye kutora matanho ekutanga kudzivirira kuratidzwa kweallergen, vanhu vanogona kunyatso gadzirisa allergy yavo uye kuderedza njodzi yekusagadzikana.
