Ese phenoxyethanol yangiza uruhu?

Ni ikifenoksiterone?
Phenoxyethanol ni glycol ether ikorwa binyuze mu guhuza amatsinda ya phenolic na ethanol, kandi isa nkaho ari amavuta cyangwa mucilage mu gihe ifite imiterere y'amazi. Ni ikintu gisanzwe kibungabunga ibintu mu mavuta yo kwisiga, kandi kiboneka muri byose kuva ku mavuta yo kwisiga mu maso kugeza ku mavuta yo kwisiga.
Phenoxyethanol igera ku ngaruka zayo zo kubungabunga ibidukikije atari binyuze mu kurwanya antioxidant ahubwo binyuze mu mikorere yayo yo kurwanya mikorobe, ibuza ndetse ikavanaho udukoko twinshi twa garama-positive na negative. Ifite kandi ingaruka zikomeye zo gukumira udukoko dutandukanye nka E. coli na Staphylococcus aureus.
Ese phenoxyethanol yangiza uruhu?
Phenoxyethanol ishobora kwica iyo uyinyoye ku rugero rwinshi. Ariko, kuyikoresha hejuru y'amazifenoksiteroneku gipimo kiri munsi ya 1.0% biracyari mu rugero rwiza.
Twaganiriye mbere niba ethanol ihinduka acetaldehyde ku ruhu ku bwinshi ndetse niba uruhu ruyinjiramo ku bwinshi. Ibi byombi ni ingenzi cyane kuri phenoxyethanol. Ku ruhu rufite uruzitiro rudahinduka, phenoxyethanol ni imwe mu ngirabuzimafatizo za glycol zisenya vuba. Niba inzira ya metabolic ya phenoxyethanol isa n'iya ethanol, intambwe ikurikiraho ni ukurema acetaldehyde idahinduka, hagakurikiraho aside phenoxyacetic na radicals zigenga.
Ntugahangayike! Ubwo twaganiraga kuri retinol mbere, twanavuze ku buryo bw'imisemburo ifitanye isano n'imikorere y'umubirifenoksiterone, kandi ko izi nzira zo guhindura ibintu ziba munsi ya stratum corneum. Bityo rero tugomba kumenya ingano ya phenoxyethanol yinjizwa mu mubiri mu buryo bunyura mu ruhu. Mu bushakashatsi bumwe bwagerageje uburyo ingurube ifata amazi irimo phenoxyethanol n'ibindi bintu birwanya mikorobe, uruhu rw'ingurube (rufite ubushobozi bwo kwinjira hafi y'abantu) rwakwinjizwa 2% bya phenoxyethanol, nabyo byariyongereye bigera kuri 1.4% gusa nyuma y'amasaha 6, na 11.3% nyuma y'amasaha 28.
Ubu bushakashatsi bwerekana ko kwinjiza no guhindurafenoksiteroneku gipimo kiri munsi ya 1% ntabwo ari hejuru bihagije kugira ngo habeho ibipimo byangiza bya metabolites. Ibisubizo nk'ibyo byabonetse mu bushakashatsi bwakorewe ku bana bavutse batarageza ku byumweru 27. Ubushakashatsi bwagize buti: "AmazifenoksiteroneNtiyangiza uruhu cyane ugereranije n'imiti ikoreshwa muri ethanol. Phenoxyethanol yinjizwa mu ruhu rw'impinja zivutse, ariko ntabwo ikora aside phenoxyacetic acid mu rugero runini." Ibi binagaragaza ko phenoxyethanol ifite igipimo kinini cy'imikorere y'umubiri mu ruhu kandi ntitera ingaruka zikomeye. Niba abana bashobora kubyihanganira, ni iki utinya?
Ni nde mwiza kurusha abandi, phenoxyethanol cyangwa alcool?
Nubwo phenoxyethanol ikorwa vuba kurusha ethanol, igipimo ntarengwa cyo gukoreshwa mu mubiri kiri hasi cyane kuri 1%, bityo si ukugereranya neza. Kubera ko stratum corneum ibuza molekile nyinshi kwinjira, radicals yigenga ikorwa n'izi ebyiri ni nke cyane ugereranyije n'izakozwe n'imikorere yazo ya oxidation buri munsi! Byongeye kandi, kubera ko phenoxyethanol irimo amatsinda ya phenolic mu buryo bw'amavuta, irashira kandi ikaruma buhoro buhoro.
Incamake
Phenoxyethanol ni imiti ikoreshwa mu kwisiga ikoreshwa mu kwisiga. Ni nziza kandi ifite akamaro, kandi ni iya kabiri kuri parabens mu bijyanye no kuyikoresha. Nubwo ntekereza ko parabens nazo ari nziza, niba ushaka ibicuruzwa bidafite parabens, phenoxyethanol ni amahitamo meza!
