Intshayelelo ngeHydroxyethylcellulose (HEC)
I-Hydroxyethylcellulose yi-chemically modified cellulose polymer ephuma kwi-cellulose ngenkqubo ye-etherification. Isetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo, kuquka amayeza, izinto zokuthambisa, kunye nokutya. Kula mashishini, i-HEC isebenza ngokuyinhloko njenge-thickening, gelling, kunye ne-ejenti yokuzinzisa ngenxa yeempawu zayo ezizodwa, ezifana nokugcinwa kwamanzi kunye nobuchule bokwenza ifilimu.
Ukusetyenziswa okuqhelekileyo kweHydroxyethylcellulose
Izithambiso: I-HEC sisithako esiqhelekileyo kwizinto zokuthambisa kunye neemveliso zokhathalelo lomntu ezifana neshampu, iiconditioner, iikhrimu, izinto zokuthambisa, kunye neegels. Inceda ekuphuculeni ukuthungwa, i-viscosity, kunye nokuzinza kwezi zakhiwo.
Amachiza: Kuqulunqo lwamayeza, i-HEC isetyenziswa njenge-thickener kunye ne-arhente exhomayo kwiifom zedosi yolwelo ezifana neesyrups, ukumiswa, kunye neegels.
Ishishini lokutya: I-HEC isetyenziswa kwishishini lokutya njenge-ejenti yokuqina kunye nokuzinzisa kwiimveliso ezahlukeneyo zokutya ezifana neesosi, izinxibo, kunye nezimuncumuncu.
Iintshukumo Zokwalana ne-Hydroxyethylcellulose
Ukuchasana nokwaliwa kwi-HEC kunqabile kodwa kunokwenzeka kubantu abasesichengeni. Ezi mpendulo zinokubonakala ngeendlela ezahlukeneyo, kuquka:
Ukucaphuka kolusu: Iimpawu zingabandakanya ububomvu, ukurhawuzelelwa, ukudumba, okanye irhashalala kwindawo yokunxibelelana. Abantu abanolusu olubuthathaka banokufumana ezi mpawu xa besebenzisa izithambiso okanye iimveliso zokhathalelo lomntu eziqulethe i-HEC.
Iimpawu zokuphefumla: Ukuphefumla amasuntswana e-HEC, ngakumbi kwiindawo zomsebenzi ezifana nezixhobo zokuvelisa, kunokukhokelela kwiimpawu zokuphefumla ezinjengokukhwehlela, ukuphefumla, okanye ukuphefumla.
Uxinzelelo lweGastrointestinal: Ukungeniswa kwe-HEC, ngokukodwa ngobuninzi okanye kubantu abaneemeko zesisu esele zikhona ngaphambili, kunokubangela iimpawu ezifana ne-nausea, ukuhlanza, okanye isifo sohudo.
I-Anaphylaxis: Kwiimeko ezinzima, ukusabela kwe-HEC kunokubangela i-anaphylaxis, imeko esongela ubomi ebonakaliswe ngokuhla ngokukhawuleza kwengcinezelo yegazi, ukuphefumula ubunzima, kunye nokulahlekelwa kwengqondo.
Ukuxilongwa kweHydroxyethylcellulose Alergy
Ukuxilongwa kwe-allergies kwi-HEC kubandakanya indibaniselwano yembali yonyango, uvavanyo lomzimba, kunye novavanyo lokwaliwa. La manyathelo alandelayo anokuthathwa:
Imbali yezoNyango: Umboneleli wezempilo uya kubuza malunga neempawu, ukuvezwa okunokwenzeka kwimveliso equkethe i-HEC, kunye nayiphi na imbali ye-allergies okanye i-allergies.
Uvavanyo loMzimba: Uvavanyo lomzimba lusenokubonisa iimpawu zokukrala kolusu okanye ezinye izinto ezibonisa ukwaliwa komzimba.
Uvavanyo lwePatch: Uvavanyo lwePatch lubandakanya ukusebenzisa inani elincinci lezinto ezinokuthi zenzeke, kubandakanya i-HEC, eluswini ukujonga nakuphi na ukuphendula. Olu vavanyo lunceda ukuchonga i-dermatitis yoqhagamshelwano.
Uvavanyo lwe-Skin Prick: Kuvavanyo lwe-skin prick, inani elincinci le-allergen extract lihlanjululwa esikhumbeni, ngokuqhelekileyo kwi-forearm okanye ngasemva. Ukuba umntu u-allergic kwi-HEC, unokuphuhlisa ukusabela kwendawo kwindawo ye-prick ngaphakathi kwe-15-20 imizuzu.
Uvavanyo lwegazi: Uvavanyo lwegazi, olufana novavanyo oluthile lwe-IgE (i-immunoglobulin E), lunokulinganisa ubukho be-HEC-specific antibodies kwi-bloodstream, ebonisa impendulo yokungabikho komzimba.
UBuchule boLawulo lweHydroxyethylcellulose Alergy
Ukulawula i-allergies kwi-HEC kubandakanya ukuphepha ukuvezwa kweemveliso eziqulethe le nxalenye kunye nokuphumeza amanyathelo onyango afanelekileyo kwiimpendulo ze-allergies. Nazi ezinye izicwangciso-qhinga:
Ukuphepha: Chonga kwaye uphephe iimveliso eziqulethe i-HEC. Oku kunokubandakanya ukufunda ngononophelo iilebhile zemveliso kunye nokukhetha ezinye iimveliso ezingenayo i-HEC okanye ezinye izithako ezinxulumene nazo.
Ukutshintshwa: Khangela ezinye iimveliso ezineenjongo ezifanayo kodwa zingaqulathanga i-HEC. Abavelisi abaninzi banikezela nge-HEC-free formulations yezithambiso, iimveliso zokhathalelo lomntu, kunye namayeza.
Unyango lwe-Symptomatic: Amayeza angaphandle kwe-counter-the-counter afana ne-antihistamines (umzekelo, i-cetirizine, i-loratadine) inokunceda ukukhulula iimpawu zokungaguquki, njengokurhawuzelela kunye ne-rash. I-corticosteroids ye-topical inokumiselwa ukunciphisa ukuvuvukala kwesikhumba kunye nokucaphuka.
ULungiselelo oluNgxamisekileyo: Abantu abanembali yokuchasana kakhulu, kuquka i-anaphylaxis, kufuneka baphathe i-epinephrine auto-injector (umzekelo, i-EpiPen) ngamaxesha onke kwaye bazi indlela yokuyisebenzisa kwimeko yongxamiseko.
Ukubonisana nababoneleli bezempilo: Xoxa nayiphi na inkxalabo okanye imibuzo malunga nokulawula i-HEC yokungahambi kakuhle kunye nabaqeqeshi bezempilo, kuquka i-allergists kunye ne-dermatologists, abanokubonelela ngesikhokelo somntu kunye neengcebiso zonyango.
Ngelixa i-hydroxyethylcellulose isisithako esisetyenziswa kakhulu kwiimveliso ezahlukeneyo, ukuchasana nokwaliwa kule khompawundi kunokwenzeka, nangona kunqabile. Ukuqaphela iimpawu kunye neempawu ze-HEC zokwaliwa, ukufuna uvavanyo olufanelekileyo lwezonyango kunye nokuxilongwa, kunye nokuphumeza izicwangciso zokulawula ezisebenzayo ngamanyathelo abalulekileyo kubantu abarhanelwa ukuba banalo lo mzimba. Ngokuqonda imingcipheko enokubakho enxulumene nokuvezwa kwe-HEC kunye nokuthatha amanyathelo asebenzayo ukuphepha ukuvezwa kwe-allergen, abantu banokulawula ngokufanelekileyo ukwaliwa kwabo kunye nokunciphisa umngcipheko wokungaphenduli.
