He kino te phenoxyethanol ki te kiri?

He aha te meaphenoxyethanol?
Ko te Phenoxyethanol he glycol ether i hangaia mā te whakakotahi i ngā rōpū phenolic me te ethanol, ā, ka puta mai hei hinu, hei mucilage rānei i roto i tōna āhua wai. He mea tiaki noa i roto i ngā mea whakapaipai, ā, ka kitea i roto i ngā mea katoa mai i ngā kirīmi kanohi ki ngā hinu kiri.
Kāore te Phenoxyethanol e whai hua tiaki i te huakita mā te ārai-pūmua engari mā te mahi ārai-pūmua, e aukati ana, e tango ana hoki i ngā horopeta nui o ngā pūmua karamu-pai me ngā pūmua kino. He pānga ārai nui anō hoki tōna ki ngā momo huakita noa pērā i te E. coli me te Staphylococcus aureus.
He kino te phenoxyethanol ki te kiri?
Ka mate pea te Phenoxyethanol ina horomia i roto i ngā horopeta nui. Heoi, ko te paninga o tephenoxyethanolkei roto tonu i te awhe haumaru ngā kukū iti iho i te 1.0%.
Kua kōrerohia e tātou i mua mēnā ka hurihia te etanoru hei acetaldehyde i roto i te nui o te kiri, ā, mēnā ka mimitihia i roto i te nui o te kiri. He mea nui hoki ēnei e rua mō te phenoxyethanol. Mō te kiri he ārai kore-kino, ko te phenoxyethanol tētahi o ngā glycol ethers tere rawa te whakaheke. Mēnā he rite te ara pākia o te phenoxyethanol ki te etanoru, ko te taahiraa e whai ake nei ko te hanganga o te acetaldehyde kore pumau, ā, muri iho ko te waikawa phenoxyacetic me ētahi atu rauropi kore utu.
Kaua e manukanuka! I tā tātou kōrero mō te retinol i mua ake nei, i kōrero anō tātou mō te pūnaha whākōkī e pā ana ki te pākia o tephenoxyethanol, ā, ko ēnei tukanga hurihanga ka puta i raro i te stratum corneum. Nō reira, me mōhio tātou ki te nui o te phenoxyethanol ka mimitia mā te kiri. I roto i tētahi rangahau i whakamātautau i te mimititanga o tētahi hiri wai kei roto ko te phenoxyethanol me ētahi atu kai ārai-pūmua, ka mimitia e te kiri poaka (he tata rawa te uruhanga ki te tangata) te 2% phenoxyethanol, ā, ka piki ake anō ki te 1.4% noa iho i muri i ngā hāora 6, me te 11.3% i muri i ngā hāora 28.
E whakaatu ana ēnei rangahau ko te mimiti me te hurihanga ophenoxyethanoli ngā kukū iti iho i te 1% kāore i te nui hei whakaputa i ngā horopeta kino o ngā metabolites. Kua whiwhihia hoki ngā hua ōrite i roto i ngā rangahau e whakamahi ana i ngā pēpi whānau hou i raro i te 27 wiki. I kī te rangahau, "Aqueousphenoxyethanolkāore e tino kino te kiri ki te whakataurite ki ngā mea tiaki e hangai ana ki te etanoru. Ka mimiti te Phenoxyethanol ki roto i te kiri o ngā pēpi whānau hou, engari kāore e hanga i te hua waikura ko te waikawa phenoxyacetic i roto i ngā rahinga nui." E whakaatu ana hoki tēnei hua ko te phenoxyethanol te mea nui rawa atu te tere o te pākia o te kiri, ā, kāore e tino kino. Mena ka taea e ngā pēpi te whakahaere, he aha tāu e wehi ai?
Ko wai te mea pai ake, te phenoxyethanol, te waipiro rānei?
Ahakoa he tere ake te mimiti o te phenoxyethanol i te ethanol, he iti iho te kukū mōrahi mō te paninga ā-kiri, arā, 1%, nō reira ehara i te mea pai te whakataurite. Nā te mea ka āraia e te stratum corneum te nuinga o ngā ngota kia mimiti, he iti iho ngā rauropi kore utu e puta mai ana i ēnei e rua i ērā e puta mai ana i ā rātou ake tauhohenga waikura i ia rā! Heoi anō, nā te mea kei roto i te phenoxyethanol ngā rōpū phenolic i roto i te ahua o te hinu, ka puhoi ake te mimiti me te maroke.
Whakarāpopototanga
He mea tiaki noa te Phenoxyethanol e whakamahia ana i roto i ngā mea whakapaipai. He haumaru, he whai hua hoki, ā, ko tōna tuarua anake ko ngā parabens ina whakamahia. Ahakoa ki taku whakaaro he haumaru hoki ngā parabens, ki te mea kei te rapu koe i ngā hua kāore he parabens, he kōwhiringa pai te phenoxyethanol!
