I-Phenoxyethanol ezithombeni: incazelo, ukusetshenziswa nokulimala

Akukona umkhiqizo owodwa wezithokozi ongawenzi ngaphandle kwemithi yokuzivikela. Yonke imikhiqizo equkethe amanzi iyinhlangano ephakathi komsoco ezinhlobonhlobo zamabhaktheriya, isikhunta kanye nezincane ezincane. Ukwengeza ukulondolozwa kubo kuvumela ukwandisa impilo yeshelufu yezimonyo futhi kuyenze iphephile. Into ejwayelekile kakhulu enezindawo ezinjalo yi-phenoxyethanol.

Incazelo

Ngokuvamile, abasebenzisi bezimonyo bakhathazeke ngombuzo walokho i-phenoxyethanol, ukuthi isetshenziselwa nokuthi kuphi. I-Phenoxyethanol i-ether ye-glycol, esetshenziselwa ukugcina imithi emikhiqizweni yezimonyo nemithi. Kuyinto uhlobo lwe-ester yotshwala enezindawo ezinamakha angathuthukisa iphunga lemikhiqizo yezimonyo. Into ewuketshezi olungenambala, olunamafutha emvelo. Ikhuluma ngamakhemikhali ephilayo anesimo semvelo ku-chicory, i-grapefruit kanye netiye elihlaza. Noma kunjalo i-phenoxyethanol ezithombeni isebenzisa izici, ezikhiqizwa ezimweni zokubhubhisa, lokhu kusiza ukudala amakhemikhali anamandla anokungcola okuncane.

Le nhlanganisela yezinto eziphilayo nayo yaziwa futhi ngezindawo zayo zokulwa namagciwane (okusebenzayo ngokumelene nemvubelo, izidalwa zebhaktheriya kanye nenkuni). Lesi sakhiwo se-phenoxyethanol saba yikho ehola phambili ekunqumeni njengendlela yokulondolozwa ngokumelene nokungcola kwe-bacteriological yemikhiqizo yezimonyo.

Umlando we-phenoxyethanol

Ukuvela kwe-phenoxyethanol njenge-main main preservative kwenzeka lapho umphakathi uqala ukuzwakala i-alamu ngengozi yokusebenzisa ama-parabens. Abakhiqizi abaningi baye baqaphela ukuthi le makhemikhali iyindlela engcono yokufaka indawo yama-parabens. Kulula ukukhiqiza, futhi kuyabiza kakhulu. Izakhiwo zokubulala izifo ze-phenoxyethanol zinganciphisa okwesikhashana ubuhlungu uma zisetshenziselwa isilonda noma zishisa indawo, futhi zingenza njenge-anti-disinfectant.

Ingozi yokusetshenziswa

I-US Food Administration and Drug Administration FDA iqhube isifundo sezinto ezifana ne-phenoxyethanol, izinzuzo kanye nokulimala kokusetshenziswa kwazo izimonyo zahlolwa. Umphumela uba mnandi: ukudla amanani amakhulu we phenoxyethanol kungaba yingozi futhi yingozi ezinganeni. Ukungena ngengozi kwezinto ezihlanzekile kungaholela ekucindezelekeni kwesimiso sezinzwa zomphakathi, kubangele ukuvela kwesifo sohudo nokuhlanza. Ngaphezu kwalokho, ukuhlangana okuhlangene kwe-phenoxyethanol ne-chlorphenesin emkhiqizo kungaholela ekucindezelekeni kokuphefumula.

Ngenxa yalezi zingozi ezingase zibe yingozi, okuqukethwe kwento efana ne-phenoxyethanol, kuzimonyo, akumele kudlulele u-1% wesisindo esiphelele, ukulimala kulokhu kuzoba okuncane. Ngaphezu kwalokho, omama abantwana abasha kufanele bagweme ukusebenzisa izimonyo eziqukethe i-phenoxyethanol, ngokuncelisa, ukuvimbela ukungena ngengozi kwemakhemikhali kumntwana.

Izakhi ze-Chemical ze phenoxyethanol

I-Phenoxyethanol ezithombeni zingaphulwa zibe yi-ethylene, i-phenyle, i-ether ne-glycol. Kuyaziwa ngamanye amagama amakhemikhali amaningana, njengePhenoxytol, Phenoxethol, Rose Ether, Phenyle Cellosolve no-Ethylene Glycol Monophenyl Ether. Phakathi nokuvivinywa kwemikhiqizo ye-dermatological, ngaphezu kokulondoloza impahla, kwatholakala impahla yamakhemikhali evimbela amakhemikhali wokulungisa emakhazeni nasensiphu. Ngenxa yokuthi iphunga aliphi i-evaporate futhi lihlala isikhathi eside.

Naphezu kokuthi abasebenzisi abaningi bakholelwa ukuthi i-phenoxyethanol ezithombeni zilimaza umzimba, iphephile ngokwemvelo futhi ilula kalula ngaphansi kwemiphumela yezinto eziphilayo. Akakwazi ukuqoqa emzimbeni futhi akakwazi ukubamba iqhaza ku-chain chain.

Ukuhambisana nezinye izingxenye

I-Phenoxyethanol iyahambisana nezinhlobo eziningi zezingxenye zokukhiqiza zezimonyozi, okuyingxenye yemikhiqizo engahlanjululwa ngamanzi nengenayo. Ibonakala ngokuzinza okushisayo, iyanqamuka emazingeni okushisa angaphezu kuka-85 degrees Celsius. Ngenxa yokuthi lisetshenziswe ngisho nasezimo eziyinkimbinkimbi zezulu, nasezinhlobonhlobo zemikhiqizo yezimonyo.

Ihlala izinzile ePn kusuka ku-3 kuya ku-10.7, ngakho-ke inganezelwa cishe noma yimuphi umkhiqizo wezithokozi, ngokuqala nge-soap alkali enamandla futhi iqede nama-gel kanye ne-foam nge-acidity ephakeme.

I-Phenoxyethanol isonophe kakhulu, inani layo eliphakeme emaphakathi liyi-0.3-1%, okungukuthi, ibhodlela elinama-milliliters angu-200 lomuthi kudinga amaconsi angu-15-20 kuphela.

Uhlobo lwemikhiqizo equkethe i-phenoxyethanol

Abathengi bavame ukukhathazeka ngombuzo wokuthi kungani i-phenoxyethanol iyadingeka ezithombeni, lapho isetshenziswa khona. Itholakala ngokuyinhloko emikhiqizweni yezithokozi nemithi, kuhlanganise namakha, emikhiqizweni yelanga, ama-shampoos, ama-creams namafutha. Embonini yamakhemikhali iphinde isetshenziselwe ukuhlanza izingubo zokugqoka, ama-bactericides, ama-inks, ama-repellents ezinambuzane, amade, ama-antiseptics, imithi yokugoma, ama-resins nama-gel spermicidal. Kubalulekile ukuqonda ukuthi kuyisigaba sesibili emikhiqizweni eminingi yokunakekela isikhumba, futhi akuhloswe ukuphatha noma yisiphi isimo noma isikhumba senkinga.

Izinzuzo ezithile zokusebenzisa i-phenoxyethanol njenge-preservative

Kunezinketho eziningi ezengeziwe zokusetshenziswa kwe-phenoxyethanol ezithombeni nasezimboni zokudla, ngaphandle kokunakekela isikhumba. Isibonelo, ikhemikhali ingeziwe ekudleni okuthile ukuze kugcinwe ukuvuselela isikhathi eside. Lezi zimakhemikhali eziphilayo zingabulala amabhaktheriya akhona ekuqanjweni kwezimonyo futhi zikholelwa ukuthi ziyi-buffer ezifanele kakhulu uma kuqhathaniswa ne-sodium azide, futhi izinga le-phenoxyethanol lokunotshisa alibalulekile kunalesi paraben. Ngaphezu kwalokho, le makhemikhali isetshenziselwa imikhiqizo eminingi yokwelapha kanye nokulungiselela ama-preservatives.

I-Phenoxyethanol ine-spectrum ebanzi yomsebenzi we-antimicrobial. Kuphumelela ukuvikela umkhiqizo kusuka ekukhuleni kwemvubelo, isikhunta, zonke izinhlobo zamabhaktheriya, kuhlanganise namagciwane aphikisana namagciwane, njengama-bacteria angenagamu, okuyizinambuzane eziyinhloko zezinqubo ezihlanzekile nezokuvuvukala. Ukuze kuthuthukiswe umphumela walo, kuvame ukungezwa ku- sorbate yokudliwa kokudla , okuya ekubunjweni kwazo zonke iziphuzo nemikhiqizo eminingi.

Imiphumela emibi evela ekusetshenzisweni kwe-phenoxyethanol

I-Phenoxyethanol uma isetshenziswe ngobuningi obudala ibangela ukulimala kwamangqamuzana obuchopho nesistimu enkulu yezinzwa. Ezinye ezinye izimo ezimbi ezingase zenzeke ngokusetshenziswa kwamakhemikhali ezinamazinga aphezulu ahlanganisa: ukucasula isikhumba, ukusabela okweqile, umdlavuza, ukuvuvukala emaphashini namehlo, i-dermatitis, ukusabela okukhulu kwesikhumba kubantu abasebenzisa i-eczema. Uma kwenzeka izinkinga zesikhumba, ukwelashwa kufanele kusetshenziswe ngokucophelela imikhiqizo ne-substance phenoxyethanol. Ezithombeni, lisetshenziswe kaningi, ngakho-ke udinga ukubukela ukwakheka. Kodwa-ke, ukuguquka komzimba nokweqa esikhumbeni kungabangeli nje kuphela ukulondolozwa, kodwa futhi nokwakheka okuyisisekelo ukhilimu, ngakho okokuqala udinga ukuyilalela.
