Isingeniso se-Hydroxyethylcellulose (HEC)
IHydroxyethylcellulose iyi-polymer ye-cellulose eguqulwe ngamakhemikhali etholakala ku-cellulose ngenqubo ye-etherification. Isetshenziswa kakhulu ezimbonini ezahlukahlukene, kufaka phakathi ezemithi, izimonyo, nezokudla. Kulezi zimboni, i-HEC isebenza ngokuyinhloko njenge-ejenti yokuqina, i-gelling, kanye ne-stabilizing ngenxa yezakhiwo zayo eziyingqayizivele, njengokugcina amanzi kanye namakhono okwenza ifilimu.
Ukusetshenziswa Okuvamile kweHydroxyethylcellulose
Izimonyo: I-HEC iyisithako esivamile ezimonyoni nasezikhiqizweni zokunakekelwa komuntu siqu njengama-shampoos, ama-conditioner, okhilimu, okokugcoba, namajeli. Kuyasiza ukuthuthukisa ukuthungwa, i-viscosity, nokuzinza kwalezi zakhiwo.
Ezemithi: Ekwenziweni kwemithi, i-HEC isetshenziswa njenge-ejenti ejiya futhi emisa okwesikhashana kumafomu omthamo owuketshezi njengamasyrups, ukumiswa, namajeli.
Imboni Yokudla: I-HEC isetshenziswa embonini yokudla njenge-ejenti ejiya futhi eqinisayo emikhiqizweni ehlukahlukene yokudla njengamasoso, okokugqoka, nama-dessert.
Ukusabela Okuguquguqukayo ku-Hydroxyethylcellulose
Ukungezwani komzimba ne-HEC akuvamile kodwa kungenzeka kubantu abathintekayo. Lokhu kusabela kungabonakala ngezindlela ezihlukahlukene, kuhlanganise:
Ukucasuka Kwesikhumba: Izimpawu zingabandakanya ububomvu, ukulunywa, ukuvuvukala, noma ukuqubuka endaweni oxhumene naye. Abantu abanesikhumba esibucayi bangase babe nalezi zimpawu lapho besebenzisa izimonyo noma imikhiqizo yokunakekelwa komuntu siqu equkethe i-HEC.
Izimpawu Zokuphefumula: Ukuhogela izinhlayiya ze-HEC, ikakhulukazi ezindaweni zokusebenza njengezindawo zokukhiqiza, kungase kubangele izimpawu zokuphefumula ezinjengokukhwehlela, ukuphefumula, noma ukuphefumula.
Ukucindezeleka Kwamathunjini: Ukungena kwe-HEC, ikakhulukazi ngobuningi noma kubantu abanezimo zesisu ezivele zikhona ngaphambili, kungabangela izimpawu ezifana nokucanuzela kwenhliziyo, ukuhlanza, noma isifo sohudo.
I-Anaphylaxis: Ezimweni ezimbi kakhulu, ukusabela okweqile ku-HEC kungabangela i-anaphylaxis, isimo esisongela ukuphila esibonakala ngokuhla okungazelelwe komfutho wegazi, ukuphefumula kanzima, nokulahlekelwa ukwazi.
Ukuxilongwa kwe-Hydroxyethylcellulose Allergy
Ukuhlonza ukungezwani komzimba ne-HEC ngokuvamile kuhilela inhlanganisela yomlando wezokwelapha, ukuhlolwa ngokomzimba, nokuhlolwa kokungezwani komzimba nezinto ezithile. Kungase kuthathwe izinyathelo ezilandelayo:
Umlando Wezokwelapha: Umhlinzeki wokunakekelwa kwezempilo uzobuza ngezimpawu, ukuchayeka okungaba khona emikhiqizweni equkethe i-HEC, nanoma yimuphi umlando wokungezwani komzimba nezinto ezithile noma ukungezwani komzimba.
Ukuhlola Umzimba: Ukuhlolwa komzimba kungase kwembule izimpawu zokucasuka kwesikhumba noma okunye ukungezwani komzimba.
Ukuhlolwa kwe-Patch: Ukuhlolwa kwe-patch kuhilela ukusebenzisa amanani amancane ezinto ezingezwani nomzimba, okuhlanganisa i-HEC, esikhumbeni ukuze ubheke noma yikuphi ukusabela. Lokhu kuhlolwa kusiza ukukhomba i-allergic contact dermatitis.
Ukuhlolwa Kwesikhumba: Ekuhlolweni kwe-skin prick, inani elincane le-allergen ekhishwe esikhumbeni, ngokuvamile ehlombe noma emhlane. Uma umuntu engezwani ne-HEC, angase athuthukise ukusabela kwendawo endaweni yokuhlaba phakathi kwemizuzu engu-15-20.
Ukuhlolwa Kwegazi: Ukuhlolwa kwegazi, njengokuhlola okuqondile kwe-IgE (immunoglobulin E), kungakala ubukhona bamasosha omzimba aqondene ne-HEC egazini, okubonisa ukusabela kokungezwani komzimba.
Amasu okuphatha we-Hydroxyethylcellulose Allergy
Ukulawula ukungezwani komzimba ne-HEC kuhilela ukugwema ukuchayeka emikhiqizweni equkethe lesi sithako nokusebenzisa izindlela zokwelashwa ezifanele zokungezwani komzimba. Nawa amasu athile:
Ukugwema: Khomba futhi ugweme imikhiqizo equkethe i-HEC. Lokhu kungase kuhlanganise ukufunda ngokucophelela amalebula omkhiqizo nokukhetha eminye imikhiqizo engenayo i-HEC noma ezinye izithako ezihlobene.
Ukufaka esikhundleni: Funa eminye imikhiqizo enezinjongo ezifanayo kodwa engaqukethe i-HEC. Abakhiqizi abaningi banikeza ukwakheka kwamahhala kwe-HEC kwezimonyo, imikhiqizo yokunakekelwa komuntu siqu, nemithi.
Ukwelashwa Ngezimpawu: Imithi etholakala ngaphandle kwe-counter njengama-antihistamine (isb, i-cetirizine, i-loratadine) ingasiza ekunciphiseni izimpawu zokungezwani komzimba, njengokuluma nokuqubuka. I-corticosteroids yama-topical ingase ibekwe ukunciphisa ukuvuvukala kwesikhumba nokucasuka.
Ukulungiselela Isimo Esiphuthumayo: Abantu abanomlando wokungezwani okukhulu komzimba, okuhlanganisa i-anaphylaxis, kufanele baphathe i-epinephrine auto-injector (isb, i-EpiPen) ngaso sonke isikhathi futhi bazi ukuthi bangayisebenzisa kanjani esimweni esiphuthumayo.
Ukubonisana Nabahlinzeki Bokunakekelwa Kwezempilo: Xoxa nganoma yikuphi ukukhathazeka noma imibuzo mayelana nokuphatha i-HEC yokungezwani komzimba nochwepheshe bezokunakekelwa kwempilo, okuhlanganisa nodokotela abangaboni ngaso linye nodokotela besikhumba, abanganikeza isiqondiso somuntu siqu kanye nezincomo zokwelapha.
Nakuba i-hydroxyethylcellulose iyisithako esisetshenziswa kakhulu emikhiqizweni ehlukahlukene, ukungezwani komzimba kule nhlanganisela kungenzeka, nakuba kungavamile. Ukuqaphela izimpawu nezimpawu zokungezwani komzimba ne-HEC, ukufuna ukuhlolwa okufanele kwezokwelapha kanye nokuxilongwa, nokusebenzisa amasu okuphatha aphumelelayo kuyizinyathelo ezibalulekile kubantu okusolakala ukuthi banalokhu kungezwani komzimba. Ngokuqonda izingozi ezingaba khona ezihlobene nokuchayeka kwe-HEC kanye nokuthatha izinyathelo ezisheshayo zokugwema ukuchayeka ezintweni ezingezwani nomzimba, abantu bangaphatha ngempumelelo ukungezwani kwabo futhi banciphise ubungozi bokungezwani komzimba.
