Phenoxyethanol ku zokuthambisa: inkcazelo, iinzuzo tywaleni

Akukho imveliso enye izithambiso ayikho ngaphandle kwisigcinakaliso. Zonke ukutya eziqulathe amanzi, ukuba eliphakathi umzimba kwiintlobo ngeentlobo iintsholongwane, umngundo kunye ezincane. Ukongeza kukho ukubola usinika ubomi zokuthambisa kwishelufa kwaye kukhuselekile. Eyona into iqhelekileyo ngempahla ezinjalo - phenoxyethanol.

incazelo

Kudla abasebenzisi zokuthambisa ukhathazwa yintoni phenoxyethanol, yintoni na kusetyenziswa nalapho inokufumaneka khona. Phenoxyethanol i kaEtere ethers esetyenziswa njenge ukubola kwiimveliso izithambiso kunye imithi. Yinto uhlobo i Ester utywala kunye kwiipropati enuka ukuba unako ukuphucula ukunonga iimveliso izithambiso. Le nto ke ulwelo enemibala emihle, olunamafutha endalweni. Libhekisela Amachiza equlethwe kwifomu zendalo chicory, grapefruit kunye neti eluhlaza. Kunjalo phenoxyethanol lisetyenziswa zokuthambisa yokufakelwa aveliswe phantsi kweemeko elebhu, oko kunceda ukudala umchiza eyomeleleyo kunye ukungcola ezimbalwa.

Le ulungelelwaniso kwakhona eyaziwa ngokuba kwiipropati yayo elwa (olusebenzayo ngokuchasene engenagwele, nokuvunda kwaye eziphilayo bacteria). Le propati phenoxyethanol abekuhambisa ukuba bakuchaza nje ukubola nxamnye kungcoliseko bacteriological iimveliso izithambiso.

imbali phenoxyethanol

Ukuvela phenoxyethanol njengoko imichiza ukubola engundoqo Kwathi xa uluntu ukuba i alarm ngeengozi parabens isandi. abenzi abaninzi baye baqaphela ukuba lo umchiza kuyindlela efanelekileyo indawo parabens. Kulula ukuba zivelise, kwaye ibiza sitshiphu. Phenoxyethanol Iipropati iintlungu avumela ukunciphisa okwethutyana intlungu kwi isicelo enxebeni okanye atshise ndawo, kwaye kananjalo enze njengoko zintsholongwane wobulali.

Ingozi evela ekusetyenzisweni

I-Ofisi US ye-Food and Drug Administration FDA waqhuba isifundo kwezinto ezifana phenoxyethanol, izibonelelo kunye konakalisa ukusetyenziswa kwayo izithambiso babe bavavanyiwe. Isiphumo mihle: ukusetyenziswa amathamo ezinkulu phenoxyethanol kunokuba ziyityhefu kwaye yingozi iintsana. nokudla ngengozi kwezinto ecocekileyo kunokubangela ukudakumba kwenkqubo luvo, ikhuthaza imbonakalo sorhudo kunye nokugabha. Ngaphezu koko, ubukho idibene phenoxyethanol kunye chlorphenesin kwi imveliso kungakhokelela ngokudandatheka sokuphefumla.

Ngenxa yezi ziphumo bezingalindelekanga ezinokuba yingozi kufuneka ingadluli-1% of isiqulatho ubunzima iyonke becandelo ezifana phenoxyethanol (phenoxyethanol), okuthambisa, kwimeko enjalo, umonakalo ziya kuba ncinci. Ukongeza, noomama kuzalwa umele akuphephe nokusebenzisa zokuthambisa eziqulathe phenoxyethanol, ukuncancisa, ukuthintela umntwana yemichiza ngengozi.

Iimpawu chemical phenoxyethanol

Phenoxyethanol okuthambisa enokwaphulwa ezantsi ethylene, phenyle, kunye ethers kaEtere. Saziwa ngamanye amagama imichiza eziliqela ezifana Phenoxytol, Phenoxethol, Rose iEtere, Phenyle cellosolve, kunye ethylene ethers monophenyl kaEtere. Ngexesha iimvavanyo, iimveliso dermatological, ukongeza ngokweempawu ilondoloza, kwafunyaniswa ipropati kwemichiza, uvimba nevumba nokugcina amakha kunye iisepha. Esithe ngezo ivumba akuthethi emoyeni kwaye ihlala ixesha elide ukusetyenziswa.

Ngaphandle kokuba abasebenzisi abaninzi bakholelwa ukuba phenoxyethanol kwi zokuthambisa kuzisa umonakalo emzimbeni, oko ukhuseleko eyahlukileyo yokusingqongileyo kwaye ngokulula ibolile kwi impembelelo eziphilayo. Yena akanako yande emzimbeni kwaye awukwazi inxaxheba kwikhonkco lokutya.

Ukuhambelana namanye amacandelo

Phenoxyethanol ukuhambisana kunye uluhlu olubanzi components izinto zokwenza imveliso izithambiso ezenza arhente ngamanzi-enyibilikayo ezingenakunyibilika. Le luphawulwa uzinzo thermal uqalisa ukubola kubushushu ngaphezu kweqondo 85 Celsius. Esithe ngezo isetyenziswa naxa iimeko zemozulu ezinzima kwaye uluhlu olubanzi iimveliso izithambiso.

Kuhleli zizinze kwi pH-3 ukuya ku-10.7, ngoko ifakwe ku phantse naziphi iimveliso izithambiso ukusuka nzima nesiphelo gel isepha kwealkali amagwebu kunye asidi.

Phenoxyethanol ngokoqoqosho kakhulu, esi sixa siphezulu yalo medium of 0.3-1%, nto leyo imvaba 200 ml-mali kuthatha kuphela 15-20 obhulowu.

iimveliso uhlobo equlethe phenoxyethanol

Abasebenzisi zidla ukhathazeke umbuzo wokuba kutheni kufuneka phenoxyethanol okuthambisa, kuba yona isicelo. Oku ikakhulu ezifumaneka kwiimveliso izithambiso kwaye zamayeza, kubandakanywa iziqholo, xa elangeni, ishampu, izithambiso kunye namafutha. Kushishino chemical kwaye lisetyenziswa ezopulayo impahla, bactericides, inks, ezigxotha izinambuzane, idayi, ebulala, amachiza, nentlaka kunye gel spermicidal. Kubalulekile ukuqonda ukuba yinxalenye yesibini ezininzi iimveliso yokhathalelo eluswini, ayenzelwanga ngenxa yonyango nayiphi na ethile imeko okanye ingxaki zolusu.

iingenelo ezithile yokusebenzisa phenoxyethanol njengoko ukubola

Kukho iinketho ezimbalwa ezongezelelweyo ukusebenzisa izinto phenoxyethanol okuthambisa kunye namashishini ukutya, ukongeza zolusu. Umzekelo, iyeza imichiza idityaniswe iimveliso ezithile ukutya ukugcina amathayara ixesha elide. Le yemichiza eziphilayo ukubulala iintsholongwane ezikhoyo imixube izithambiso, kwaye zithathwa ngokuba buffer endaweni efanelekileyo eziphilayo kuthelekiswa sodium azide, yaye inqanaba phenoxyethanol zinetyhefu lingaphantsi ebonakalayo ngaphezu koko kwezi paraben. Ukongezelela, amachiza asetyenziswa iimveliso ezininzi zoxubo mayeza kunye kumalungiselelo kwisigcinakaliso.

Phenoxyethanol has emininzi ebanzi yomsebenzi elwa. Oku kuyaphumelela ukukhusela imveliso evela ukukhula igwele, ukungunda, zonke iintlobo iintsholongwane, kuquka nabo ukumelana nemithi, ezifana Igram-negative iibhaktheriya, ezo arhente eziphambili ubovu kunye neenkqubo arhabaxa. Ukuze ukomeleza amanyathelo yayo, ngokuqhelekileyo kuyo isibini of kongezwa ukubola ukutya potassium sorbate, nto leyo ubunjwe zonke iziselo kunye nokutya ezininzi.

ziziphumo ebezingalindelekanga ezivela ekusetyenzisweni phenoxyethanol

Phenoxyethanol, xa esetyenziswa kukuninzi yenza umonakalo kwiiseli yobuchopho kunye nenkqubo luvo. Eminye imiphumela emibi kunokwenzeka nokusetyenziswa kwemichiza kwi ngeedosi eziphezulu ziquka: kwesikhumba, negazi, umhlaza, nangokurhala emiphungeni kunye amehlo, dermatitis, isikhumba reaction kakhulu kubantu nokujongana nerhashalala. Ukuba uneengxaki aleji kufuneka balumke xa usebenzisa iimveliso kunye phenoxyethanol kweziyobisi. Xa zokuthambisa, isetyenziswa rhoqo ngokwaneleyo, ngoko ke kufuneka ukubukela nokwakheka. Noko ke, allergies kunye njengamaqhakuva kwi nesikhumba kungabangela ukubola nje kuphela, kodwa isakhiwo esisiseko ye-cream, ngoko kuqala kwiinto zonke, kufuneka sinikele ingqalelo kuyo.
