Ingabe uPhenoxyethanol ulimaza isikhumba?

Yiniphenoxyethanol?
UPhenoxyethanol uyi-glycol ether eyakhiwa ngokuhlanganisa amaqembu we-phenol nge-ethanol, futhi avela njengamafutha noma mucilage esimweni sawo se-liquid. Kungukugcina okuvamile ezimotweni, futhi kungatholakala kukho konke kusuka kukhilimu wobuso kuya ku-lotions.
IPhenoxyethanol ifinyelela umphumela wayo wokugcina hhayi nge-antioxidant kodwa ngomsebenzi wayo wokulwa namagciwane, okuvimbela futhi asuse imithamo emikhulu yama-gram-posertive alungile nama-microorganisms amabi. Iphinde ibe nomphumela obalulekile wokuvimbela ku-bacteriya ajwayelekile afana ne-E. Coli noStaphylococcus aureus.
Ingabe uPhenoxyethanol ulimaza isikhumba?
UPhenoxyethanol angaba lubuleleke lapho engeniswe emithanjeni emikhulu. Noma kunjalo, ukusetshenziswa kwe-topical ofphenoxyethanolekugxiliseni okungaphansi kwama-1.0% kusengaphakathi kobubanzi obuphephile.
Phambilini saxoxa phambilini ukuthi i-ethanol ihlanganiswe ne-acetaldehyde ngobuningi besikhumba nokuthi ingahle imunwe ngamanani amakhulu ngesikhumba. Zombili lezi zibalulekile futhi kuPhenoxyethanol. Ukuze isikhumba esinomgoqo ongaqondile, uPhenoxyethanol ungenye yezithako ezisheshayo ze-glycol esonakalisayo. Uma indlela ye-metabolilic yePhenoxyethanol ifana ne-ethanol, isinyathelo esilandelayo ukwakheka kwe-acetaldehyde engazinzile, elandelwa yi-phenoxyacetic acid kanye nama-radicals mahhala.
Ungakhathazeki okwamanje! Lapho sixoxa nge-retinol phambilini, siphinde sakhuluma nohlelo lwe-enzyme oluhlotshaniswa ne-metabolism yephenoxyethanol, nokuthi lezi zinqubo zokuguqula zenzeke ngaphansi kweStratum Corneum. Ngakho-ke kudingeka sazi ukuthi i-phenoxyethanol empeleni imunca nje transdermally. Kokunye ukuhlola okwakuhlola ukufakwa kwe-balant esekelwe emanzini aqukethe i-phenoxyethanol nezinye izithako ezilwa namagciwane, isikhumba esiseduze kakhulu kubantu) ngemuva kwamahora ayi-6, futhi ngo-11.3% ngemuva kwamahora angama-28.
Lezi zifundo zibonisa ukuthi ukumunca nokuguqulwa kwephenoxyethanolLapho kugxila ngaphansi kwe-1% akuphezulu ngokwanele ukukhiqiza imithamo eyingozi ye-metabolites. Imiphumela efanayo nayo itholwe ezifundweni ezisebenzisa izinsana ezisanda kuzalwa ezingaphansi kwamaviki angama-27. Isifundo Esishiwo, "AquadphenoxyethanolAkubangeli ukulimala kwesikhumba okubalulekile uma kuqhathaniswa nezindawo ezisekelwe e-Ethanol. UPhenoxyethanol uyabangelwa esikhunjeni sezingane ezisanda kuzalwa, kepha akenzi i-oxidation Product Phenoxyacetic acid ngamanani abalulekile. "Lo mphumela futhi ukhombisa ukuthi uPhenoxyethanol unesilinganiso esiphakeme kakhulu se-metabolism esikhunjeni futhi asibangeli ukulimala okukhulu.
Ngubani ongcono, phenoxyethanol noma utshwala?
Yize uPhenoxyethanol ahlaselwe ngokushesha kune-ethanol, okuhlushwa okuvinjelwe okukhawulelwe kwesicelo esiphezulu kuphansi kakhulu ku-1%, ngakho-ke akukhona ukuqhathanisa okuhle. Njengoba i-stratum Corneum ivimbela iningi lama-molecule ukuthi lingangeni, ama-radicals amahhala akhiqizwa yilezi ezimbili angaphansi kakhulu kunalawo akhishwe yi-opidation activation nsuku zonke! Ngaphezu kwalokho, ngoba iPhenoxyethanol iqukethe amaqembu we-phenolic ngesimo samafutha, ivele futhi iyoma kancane.
Ukubeka kafushane
UPhenoxyethanol uyisimo esivamile sokulondolozwa esisetshenziswa kwezimonyo. Kuphephile futhi kuyasebenza, futhi kungokwesibili kuphela kumapharabhuki ngokuya ngokusetshenziswa. Yize ngicabanga ukuthi amaParabens nawo aphephile, uma ufuna imikhiqizo ngaphandle kwamaParabens, Phenoxyethanol ukukhetha okuhle!
