E ʻimi i ka palekana o Methyl 4-hydroxybenzoate Methylparaben i nā huahana mālama pilikino

ʻO Methyl 4-hydroxybenzoate Methylparaben kekahi o nā parabens, he mea mālama me ke ʻano kemika CH3(C6H4(OH)COO). ʻO ia ka methyl ester o ka p-hydroxybenzoic acid.
ʻO Methyl 4-hydroxybenzoate Methylparaben ka lawelawe ma ke ʻano he pheromone no nā ʻano pepeke a he ʻāpana o ka pheromone mandibular mōʻīwahine.
He pheromone ia i loko o nā ʻīlio hae i hana ʻia i ka wā estrus e pili ana i ke ʻano o nā ʻīlio kāne alpha e pale ana i nā kāne ʻē aʻe mai ke kau ʻana i nā wahine i ka wela.
ʻO Methyl 4-hydroxybenzoate Methylparaben kahi mea anti-fungal i hoʻohana pinepine ʻia i nā ʻano mea hoʻonaninani a me nā huahana mālama pilikino. Hoʻohana ʻia ia ma ke ʻano he mea mālama meaʻai.
Hoʻohana pinepine ʻia ʻo Methyl 4-hydroxybenzoate Methylparaben ma ke ʻano he fungicide ma Drosophila meaʻai media ma 0.1%. No Drosophila, he mea make ka methyl 4-hydroxybenzoate methylparaben i nā kiʻekiʻe kiʻekiʻe, he hopena estrogenic (e hoʻohālike ana i ka estrogen i nā ʻiole a me ka hana anti-androgenic), a hoʻolohi i ka ulu ʻana o ka ulu ʻana i ka pae larval a me ka pupal ma 0.2%.
Aia ka hoʻopaʻapaʻa e pili ana i ka methyl 4-hydroxybenzoate methylparaben a i ʻole propylparabens he mea pōʻino i ka hoʻohana maʻamau i ka mālama kino a i ʻole nā ​​mea hoʻonaninani. ʻO ka Methylparaben a me ka propylparaben i manaʻo ʻia he palekana (GRAS) e ka USFDA no ka mālama ʻana i ka meaʻai a me ka mālama ʻana i ka antibacterial. Hoʻopili koke ʻia ka Methyl 4-hydroxybenzoate Methylparaben e ka maʻi bacteria lepo maʻamau, e hoʻolilo iā ia i biodegradable.
Hoʻopili koke ʻia ka Methyl 4-hydroxybenzoate Methylparaben mai ka ʻāpana ʻōpū a i ʻole ma o ka ʻili. Hoʻopili ʻia i ka waika p-hydroxybenzoic a hoʻokuʻu koke ʻia i loko o ka mimi me ka ʻole o ka hōʻiliʻili ʻana i loko o ke kino. Ua hōʻike ʻia nā haʻawina ʻona koʻikoʻi he mea ʻawaʻawa ʻole ka methylparaben e ka hoʻokele waha a me ka makua i nā holoholona. I ka heluna kanaka me ka ʻili maʻamau, ʻo ka methylparaben ka mea hiki ʻole ke hoʻonāukiuki a me ke ʻano ʻole; akā naʻe, ua hōʻike ʻia nā hopena maʻi i nā parabens i ʻai ʻia. ʻAʻole ʻike ʻia kahi haʻawina 2008 i ka hoʻokūkū hoʻokūkū no ka estrogen kanaka a me nā mea hoʻokipa androgen no ka methylparaben, akā ʻike ʻia nā pae like ʻole o ka hoʻopaʻa ʻana me ka butyl- a me ka isobutyl-paraben.
Hōʻike nā haʻawina i ka methylparaben i hoʻohana ʻia ma ka ʻili e pane me UVB, e alakaʻi ana i ka hoʻonui ʻana i ka ʻili a me ka pōʻino DNA.
I ka pane ʻana i kēia mau hopohopo, ua hana kekahi mau keʻena hoʻoponopono a me nā hui i nā hana e kāohi ai i ka hoʻohana ʻana i ka methyl paraben i kekahi mau huahana. No ka laʻana, ua kaupalena ka European Union i ka neʻe ʻana o ka methyl paraben i ʻae ʻia i nā mea hoʻonaninani, a ua koho kekahi mau mea hana e hoʻoponopono hou i kā lākou huahana me ka paraben-free. Eia kekahi, ke ulu nei ka noi no nā mea kūlohelohe a me nā mea kūlohelohe i nā preservatives kuʻuna i alakaʻi i ka hoʻomohala ʻana i nā ʻano hou i loaʻa ʻole ka methyl paraben a i ʻole nā ​​​​parabens ʻē aʻe.
Makemake ʻia ʻo Methylparaben no kona kūpaʻa a me ka hoʻohālikelike ʻana me nā ʻano hana like ʻole. ʻAʻole ia e hoʻololi i ka waihoʻoluʻu, ʻala, a i ʻole ke ʻano o nā huahana i hoʻohana ʻia, e hoʻolilo iā ia i mea hoʻohui no ka mea hana. Hoʻonui kēia kūpaʻa i ke ola o ka papa a kōkua i ka mālama ʻana i ka maikaʻi holoʻokoʻa o ka huahana no ka wā lōʻihi.

Pono nā mea kūʻai aku e hoʻomaopopo i ko lākou naʻau pilikino a me nā maʻi allergies i ka wā e hoʻohana ai i nā huahana me ka methylparaben. ʻOiai ua manaʻo ʻia ka methylparaben he palekana no ka hoʻohana ʻana i nā mea hoʻonaninani, hiki i kekahi poʻe ke ʻike i ka ʻili ʻili a i ʻole ka hopena maʻi. Manaʻo mau ʻia e hana i kahi hoʻāʻo patch ma mua o ka hoʻohana ʻana i kahi huahana hou e hoʻoholo ai inā loaʻa nā hopena ʻino.
I ka hopena, ʻo ka methyl 4-hydroxybenzoate a i ʻole methylparaben he mea mālama nui i hoʻohana ʻia i nā ʻoihana hoʻonaninani a me nā lāʻau lapaʻau. ʻOiai ka hoʻopaʻapaʻa ma muli o nā hopohopo e pili ana i kona hopena i ka pae o ka hormone a me ke olakino hānau, ua mau ia i kahi koho kaulana no ka mālama ʻana i nā huahana ma muli o kona pono, kūpaʻa, a me ka hoʻohālikelike ʻana me nā ʻano hana like ʻole. Ke hoʻomau nei ka noi no nā huahana kūlohelohe a me nā mea kūlohelohe, hiki ke ulu ka hoʻohana ʻana i ka methylparaben a ʻoi aku ka nui o nā preservatives i ka mākeke. Pono nā mea kūʻai aku e hoʻomaopopo i nā mea i loko o nā huahana a lākou e hoʻohana ai a hana i nā koho e kūlike me kā lākou makemake pilikino a me nā hopohopo.
