ʻO ka Vitamin A Acetate: Mea Anti-Aging Ingredient no nā meaʻai meaʻai a me nā mea hoʻonani

●He aha ka Vitamin A Acetate?

ʻO Retinyl Acetate, inoa kemika retinol acetate, molecular formula C22H30O3, CAS helu 127-47-9, he esterified derivative o ka huaʻa A. Ke hoʻohālikelike ʻia me ka waiʻona A waiʻona, hoʻonui ia i ka paʻa ma o ka hopena esterification a pale i ka decomposition oxidative, lilo i mea waiwai nui i ke kula o ka meaʻai, lāʻau lapaʻau a me nā mea hoʻonaninani.

 

Loaʻa ka nui o ka huaora A maoli i loko o ka ate holoholona a me ka iʻa, akā ʻo ka hana ʻoihana ka hapa nui o ka hoʻohana ʻana i ka synthesis kemika, e like me ka hoʻohana ʻana i ka β-ionone ma ke ʻano he precursor a me ka hoʻomākaukau ʻana ma o Wittig condensation reaction. I nā makahiki i hala iho nei, ua puka mai nā ʻenehana hoʻomākaukau ʻōmaʻomaʻo e like me ka ultrasound-enhanced interfacial enzyme catalysis, me ka hoʻomaikaʻi nui ʻana i ka hopena maikaʻi a me ka hoʻohaʻahaʻa ʻana i ka pollution, lilo i alakaʻi nui no ka hoʻonui ʻana i ka ʻenehana ʻoihana.

 

Vitamin A acetatehe keʻokeʻo a me ka māmā melemele crystalline pauka a i ʻole ka wai ʻeleʻele me kahi helu heheʻe o 57-58°C, kahi paila e pili ana i 440.5°C, kahi kiko o 1.019 g/cm³, a me kahi helu refractive o 1.547-1.555. Loaʻa iā ia ka momona momona nui a hiki ke maʻalahi i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka etera, akā he ʻilihune ka wai, a pono e microencapsulated e hoʻomaikaʻi i kona dispersibility i ka meaʻai.

 

Ma ke ʻano o ke kūpaʻa, ʻike ʻia ka vitamin A acetate i ka māmā, ka wela a me ka oxygen, a pono e mālama ʻia mai ka mālamalama (2-8 ° C), a ua hoʻohui ʻia nā antioxidants e like me BHT e hoʻolōʻihi i ke ola. He kiʻekiʻe kona bioavailability e like me 80% -90%, a ua hoʻololi ʻia i retinol e ka hydrolysis enzymatic i ke kino a komo i ka metabolism physiological.

 

● He aha nā pono oVitamin A Acetate?

1. ʻIke a me ka hoʻoponopono kino

Ma ke ʻano he ʻano ikaika o ka vitamina A, komo ia i ka hoʻokumu ʻana i ka hihiʻo ma ka hoʻololi ʻana i retinal, pale i ka pō a me ka maʻi maka maloʻo. I ka manawa like, hoʻonui ia i ka hana pale o nā cell epithelial a hōʻemi i ka hopena o nā maʻi hanu. Ua hōʻike ʻia nā hoʻokolohua lapaʻau hiki ke hoʻomaikaʻi i ka pale ʻana o nā keiki ma 30%.

 

2. ʻIli Anti-Aging A Hoʻoponopono

Kāohi i ka hoʻonui nui ʻana o nā keratinocytes, hoʻoikaika i ka synthesis collagen, a hoʻemi i ka hohonu wrinkle ma 40%. ʻO ka hoʻohui ʻana i ka 0.1% -1% ka hoʻopaʻa ʻana i nā mea hoʻonaninani hiki ke hoʻomaikaʻi i ka photoaging a me nā ʻeleʻele. No ka laʻana, hoʻohana ʻo Lancome's Absolue series cream i kēia ma ke ʻano he kumu anti-aging.

 

3. Metabolism a me ka maʻi Adjuvant lapaʻau

Hoʻoponopono i ka lipid metabolism a hoʻohaʻahaʻa i ka pae cholesterol. Ua hōʻike ʻia nā hoʻokolohua holoholona e hiki ke hoʻopaneʻe i ka piʻi ʻana o ka maʻi momona momona ʻole. Eia kekahi, i ka mālama ʻana i ka maʻi maʻi adjuvant, hōʻike ia i ka waiwai noi ma o ka hoʻoulu ʻana i ka apoptosis cell tumor.
