Sunsafe-DHA / Dihydroxyacetone

ʻO ka wehewehe pōkole:

Hoʻopili ʻo Dihydroxyacetone i ka ʻili ma ka hoʻopaʻa ʻana i nā amine, nā peptides a me nā ʻakika amino manuahi o nā papa waho o ka stratum conrneum e hoʻohua ai i kahi hopena Maillard. Hoʻokumu ʻia kahi "tan" ʻeleʻele i loko o ʻelua a ʻekolu paha mau hola ma hope o ka pili ʻana o ka ʻili i ka DHA, a hoʻomau i ka pōʻeleʻele no ʻeono mau hola. ʻO ka mea kaulana loa o ka sunless tanning agent. ʻO ia wale nō ka lāʻau tanning i ʻae ʻia e ʻAmelika FDA.

Palapala noi

Ma kahi i manaʻo ʻia he uʻi ka ʻili ʻeleʻele, ke ulu nei ka ʻike o ka poʻe i nā hopena ʻino o ka lā a me ka pilikia o ka maʻi kanesa ʻili. Ke ulu nei ka makemake e kiʻi i kahi ʻeleʻele maoli me ka ʻole o ka lā. Ua hoʻohana maikaʻi ʻia ʻo Dihydroxyacetone, a i ʻole DHA, ma ke ʻano he mea hoʻomaʻemaʻe ponoʻī no ka hapalua haneli. ʻO ia ka mea hana nui i loko o nā hoʻomākaukau mālama ʻili ʻili ʻole o ka lā, a ua manaʻo ʻia ʻo ia ka mea hoʻohui ʻoi aku ka maikaʻi loa.

Puna Kūlohelohe

ʻO DHA kahi kōpaʻa 3-carbon i komo i ka metabolism carbohydrate i nā mea kanu a me nā holoholona kiʻekiʻe ma o ka hana e like me ka glycolysis a me ka photosynthesis. He huahana physiologic ia o ke kino a ua manaʻo ʻia ʻaʻole ʻona.

Hoʻokumu Molecular

Loaʻa ka DHA ma ke ʻano he hui ʻana o kahi monomer a me 4 dimer. Hoʻokumu ʻia ka monomer ma ka hoʻomehana ʻana a me ka hoʻoheheʻe ʻana i ka DHA dimeric a i ʻole ka hoʻoheheʻe ʻana i ka wai. Hoʻihoʻi hou nā kristal monomeric i nā ʻano dimeric ma kahi o 30 mau lā o ka waiho ʻana ma ka lumi wela. No laila, loaʻa ka DHA paʻa ma ke ʻano dimeric.

Ka Hana Browning

Hoʻopili ʻo Dihydroxyacetone i ka ʻili ma ka hoʻopaʻa ʻana i nā amine, nā peptides a me nā ʻakika amino manuahi o nā papa waho o ka stratum conrneum e hoʻohua ai i kahi hopena Maillard. Hoʻokumu ʻia ka "tan" ʻeleʻele i loko o ʻelua a ʻekolu mau hola ma hope o ka pili ʻana o ka ʻili i ka DHA, a hoʻomau i ka pōʻeleʻele no ʻeono mau hola. ʻO ka hopena he ʻeleʻele nui a hoʻemi wale ʻia i ka wā e paʻa ai nā ʻili make o ka papa horney.

ʻO ka ikaika o ka tan ma muli o ke ʻano a me ka mānoanoa o ka papa horny. Ma kahi o ka mānoanoa o ka stratum corneum (ma nā kuʻekuʻe, no ka laʻana), ʻeleʻele ke kala. Ma kahi ʻeleʻele ka papa horney (e like me ka maka) ʻaʻole ʻoi aku ka ikaika o ka tan.
