Chiiphenoxyethanol?
Phenoxyethanol iglycol ether inoumbwa nekubatanidza mapoka ephenolic neethanol, uye inoonekwa semafuta kana mucilage muchimiro chayo chemvura. Inoshandiswa zvakanyanya muzvizoro, uye inowanikwa mune zvese kubva kumakirimu ekumeso kusvika kumafuta anonhuhwirira.
Phenoxyethanol inoita basa rayo rekuchengetedza kwete kuburikidza ne antioxidant asi kuburikidza nekushanda kwayo kwekurwisa mabhakitiriya, izvo zvinodzivisa uye zvinotobvisa madhigirii akawanda e gram-positive ne negative microorganisms. Inewo simba guru rekudzivirira mabhakitiriya akasiyana-siyana akajairika akadai seE. coli neStaphylococcus aureus.
Ko phenoxyethanol inokuvadza ganda here?
Phenoxyethanol inogona kuuraya kana ikanwiwa yakawanda. Zvisinei, kushandiswa kwayo pamusoro pemvura.phenoxyethanolpahuwandu huri pasi pe1.0% huchiri mukati mehuwandu hwakachengeteka.
Takambokurukura kana ethanol ichigadziriswa kuita acetaldehyde yakawanda paganda uye kana ichinyudzwa yakawanda neganda. Zvese izvi zvakakoshawo kune phenoxyethanol. Kune ganda rine chipingamupinyi chisina kukanganiswa, phenoxyethanol ndeimwe yeglycol ethers inokurumidza kushatisa. Kana nzira yemetabolism yephenoxyethanol yakafanana neye ethanol, danho rinotevera kuumbwa kweacetaldehyde isina kugadzikana, ichiteverwa nephenoxyacetic acid uye zvimwe free radicals.
Usazvidya mwoyo parizvino! Patakakurukura nezve retinol kare, takataurawo nezve system ye enzymes ine chekuita ne metabolism yephenoxyethanol, uye kuti maitiro aya ekushandura anoitika pasi pe stratum corneum. Saka tinofanira kuziva kuti phenoxyethanol yakawanda sei inonyudzwa kuburikidza ne transdermally. Mune imwe ongororo yakaedza kunyudzwa kwe sealant ine mvura ine phenoxyethanol nezvimwe zvinhu zvinorwisa utachiona, ganda renguruve (rinopindira zvakanyanya kupfuura vanhu) raizonyudzwa 2% phenoxyethanol, iyo yakawedzerawo kusvika 1.4% chete mushure memaawa matanhatu, uye 11.3% mushure memaawa makumi maviri nemasere.
Zvidzidzo izvi zvinoratidza kuti kunyudzwa nekushandurwa kwephenoxyethanolPahuwandu huri pasi pe1%, huwandu uhwu hahuna kukwana kuti hugadzire madhigirii anokuvadza emetabolites. Zvakafanana zvakawanikwawo muzvidzidzo zvakashandisa vacheche vachangoberekwa vari pasi pemavhiki makumi maviri nemanomwe. Chidzidzo ichi chakati, "Aqueousphenoxyethanolhaikonzeri kukuvara kweganda zvakanyanya kana tichienzanisa nezvinochengetedza zvinobva muethanol. Phenoxyethanol inonyudzwa muganda revacheche vachangoberekwa, asi haiumbi phenoxyacetic acid inogadzirwa neoxidation yakawanda." Mhedzisiro iyi inoratidzawo kuti phenoxyethanol ine mwero wepamusoro wemetabolism muganda uye haikonzeri kukuvara kwakanyanya. Kana vacheche vachigona kuzvibata, chii chaunotya?
Ndiani ari nani, phenoxyethanol kana doro?
Kunyangwe phenoxyethanol ichigadziriswa nekukurumidza kupfuura ethanol, huwandu hwakaganhurirwa hwekushandiswa kwemafuta emuviri hwakaderera zvikuru pa1%, saka haisi kuenzanisa kwakanaka. Sezvo stratum corneum ichidzivirira mamorekuru mazhinji kuti asanyurwe, ma free radicals anokonzerwa neaya maviri mashoma zvikuru pane ayo anokonzerwa ne oxidation reactions dzavo zuva nezuva! Uyezve, nekuti phenoxyethanol ine phenolic groups muchimiro chemafuta, inopwa uye inooma zvishoma nezvishoma.
Pfupiso
Phenoxyethanol chinhu chinoshandiswa zvakanyanya muzvizoro. Chakachengeteka uye chinoshanda, uye chinoteverwa nemaparabens pakushandiswa. Kunyangwe ndichifunga kuti maparabens akachengetekawo, kana uchitsvaga zvigadzirwa zvisina maparabens, phenoxyethanol isarudzo yakanaka!
