He pōʻino anei ka phenoxyethanol i ka ʻili?

He ahaphenoxyethanol?
ʻO Phenoxyethanol kahi glycol ether i hana ʻia ma ka hui ʻana i nā hui phenolic me ka ethanol, a ʻike ʻia ʻo ia he ʻaila a i ʻole mucilage i kona kūlana wai.He mea mālama maʻamau ia i nā mea hoʻonaninani, a hiki ke loaʻa i nā mea āpau mai ka holika maka a i nā lotions.
Loaʻa ka Phenoxyethanol i kāna hopena mālama ʻaʻole ma o ka antioxidant akā ma o kāna hana anti-microbial, ka mea e kāohi a hoʻoneʻe i nā kumu nui o nā microorganisms maikaʻi a maikaʻi ʻole.He hopena paʻa koʻikoʻi ko ia ma nā ʻano bacteria maʻamau e like me E. coli a me Staphylococcus aureus.
He pōʻino anei ka phenoxyethanol i ka ʻili?
Hiki i ka Phenoxyethanol ke make ke hoʻohana ʻia i nā ʻano nui.Eia naʻe, ka hoʻohana kumuhana ophenoxyethanolma nā haʻahaʻa haʻahaʻa ma lalo o 1.0% aia nō i loko o ka pae palekana.
Ua kūkākūkā mua mākou inā ua hoʻololi ʻia ka ethanol i ka acetaldehyde i nā mea nui ma ka ʻili a inā e komo nui ʻia e ka ʻili.He mea koʻikoʻi kēia mau mea ʻelua no ka phenoxyethanol.No ka ʻili me kahi pale paʻa, ʻo phenoxyethanol kekahi o nā glycol ethers hoʻohaʻahaʻa wikiwiki loa.Inā like ke ala metabolic o ka phenoxyethanol me ka ethanol, ʻo ka hana aʻe ka hana ʻana o ka acetaldehyde paʻa ʻole, a ukali ʻia e ka phenoxyacetic acid a me nā radical manuahi ʻē aʻe.
Mai hopohopo i kēia manawa!I ko mākou kūkākūkā ʻana i ka retinol ma mua, ua ʻōlelo pū mākou i ka ʻōnaehana enzyme e pili ana i ka metabolism ophenoxyethanol, a ke hana nei kēia mau hana hoʻololi ma lalo o ka stratum corneum.No laila pono mākou e ʻike i ka nui o ka phenoxyethanol i hoʻopili maoli ʻia i ka transdermally.I loko o kahi noiʻi i ho'āʻo i ka absorption o ka wai-based sealant i loaʻa ka phenoxyethanol a me nā mea anti-microbial ʻē aʻe, ʻo ka ʻili puaʻa (ʻo ia ka mea kokoke loa i ke kanaka) e komo i ka 2% phenoxyethanol, i hoʻonui ʻia i ka 1.4% wale nō ma hope o 6 mau hola. a me 11.3% ma hope o 28 hola.
Hōʻike kēia mau haʻawina i ka absorption a me ka hoʻololi ʻana ophenoxyethanolʻAʻole lawa ka kiʻekiʻe ma lalo o ka 1% no ka hoʻohua ʻana i nā kino kino o nā metabolites.Ua loaʻa nā hopena like i nā haʻawina e hoʻohana ana i nā pēpē hānau hou ma lalo o 27 pule.Ua ʻōlelo ka haʻawina, "Aqueousphenoxyethanolʻaʻole ia e hōʻeha nui i ka ʻili i hoʻohālikelike ʻia me nā preservatives-based ethanol.Hoʻokomo ʻia ka Phenoxyethanol i loko o ka ʻili o nā pēpē hānau hou, akā ʻaʻole ia e hana i ka waika oxidation phenoxyacetic acid i ka nui." Hōʻike pū ʻia kēia hopena i ka phenoxyethanol ka nui o ka metabolism i loko o ka ʻili a ʻaʻole ia e hoʻopōʻino nui. Inā hiki i nā pēpē. e mālama, he aha kāu e makaʻu ai?
ʻO wai ka maikaʻi, phenoxyethanol a i ʻole ka waiʻona?
ʻOiai ʻoi aku ka wikiwiki o ka phenoxyethanol ma mua o ka ethanol, ʻoi aku ka haʻahaʻa o ka neʻe ʻana no ka noi topical ma 1%, no laila ʻaʻole ia he hoʻohālikelike maikaʻi.Ma muli o ka pale ʻana o ka stratum corneum i ka hapa nui o nā molekala mai ke komo ʻana, ʻoi aku ka liʻiliʻi o nā radical manuahi i hana ʻia e kēia mau mea ʻelua ma mua o nā mea i hana ʻia e kā lākou hoʻoheheʻe ʻana i kēlā me kēia lā!Eia kekahi, no ka loaʻa ʻana o nā hui phenolic i ka phenoxyethanol ma ke ʻano o ka aila, e hoʻoheheʻe ʻia a maloʻo mālie.
Hōʻuluʻulu manaʻo
ʻO Phenoxyethanol kahi mālama mālama maʻamau i hoʻohana ʻia i nā mea hoʻonaninani.He palekana a maikaʻi hoʻi, a ʻo ia ka lua o ka parabens ma ke ʻano o ka hoʻohana ʻana.ʻOiai ke manaʻo nei au he palekana hoʻi nā parabens, inā ʻoe e ʻimi nei i nā huahana me ka ʻole o ka parabens, he koho maikaʻi ka phenoxyethanol!
