Vitamini A Acetate: Chofunikira Choletsa Kukalamba Chazakudya Zowonjezera Zaumoyo ndi Zodzoladzola

●Ndi chiyani Vitamini A Acetate?

Retinyl Acetate, mankhwala dzina retinol acetate, molecular formula C22H30O3, CAS nambala 127-47-9, ndi yochokera esterified ya vitamini A. Poyerekeza ndi vitamini A mowa, imapangitsa bata kudzera esterification reaction ndipo amapewa kuwonongeka kwa okosijeni, kukhala zofunika zopangira mankhwala, ndi cosmetics.

 

Vitamini A wachilengedwe amapezeka makamaka m'chiwindi cha nyama ndi nsomba, koma kupanga mafakitale kumagwiritsa ntchito kaphatikizidwe ka mankhwala, monga kugwiritsa ntchito β-ionone ngati kalambulabwalo ndikukonzekera kudzera mu Wittig condensation reaction. M'zaka zaposachedwapa, wobiriwira kukonzekera matekinoloje monga ultrasound-kumatheka interfacial puloteni catalysis anatulukira, kwambiri kuwongolera anachita dzuwa ndi kuchepetsa kuipitsidwa, kukhala chinsinsi malangizo makampani kukweza luso.

 

Vitamini A acetatendi ufa wonyezimira wonyezimira wonyezimira wachikasu kapena viscous madzi osungunuka ndi 57-58 ° C, malo otentha okwana pafupifupi 440.5 ° C, kachulukidwe ka 1.019 g/cm³, ndi index refractive ya 1.547-1.555. Ili ndi kusungunuka kwakukulu kwamafuta ndipo imasungunuka mosavuta mu zosungunulira za organic monga ethanol ndi ether, koma imakhala ndi madzi osungunuka bwino, ndipo imayenera kukhala ndi microencapsulated kuti ipititse patsogolo dispersibility mu chakudya.

 

Pankhani ya bata, vitamini A acetate imakhudzidwa ndi kuwala, kutentha ndi mpweya, ndipo imayenera kusungidwa kutali ndi kuwala (2-8 ° C), ndipo ma antioxidants monga BHT amawonjezeredwa kuti awonjezere moyo wa alumali. Bioavailability yake ndi yokwera mpaka 80% -90%, ndipo imasinthidwa kukhala retinol ndi enzymatic hydrolysis m'thupi ndikuchita nawo kagayidwe kazachilengedwe.

 

● Kodi Ubwino Wake Ndi ChiyaniVitamini A Acetate?

1. Kuwona ndi Kuwongolera Chitetezo cha Chitetezo

Monga mawonekedwe a vitamini A, amatenga nawo mbali pakupanga masomphenya mwa kusandulika kukhala retinal, kuteteza khungu la usiku ndi matenda a maso owuma. Pa nthawi yomweyo, timapitiriza chotchinga ntchito ya maselo epithelial ndi kuchepetsa chiopsezo cha matenda kupuma. Mayesero azachipatala awonetsa kuti amatha kusintha chitetezo cha ana ndi 30%.

 

2. Khungu Anti-Kukalamba Ndi Kukonza

Imalepheretsa kuchuluka kwa keratinocyte, imathandizira kaphatikizidwe ka collagen, ndipo imachepetsa kuya kwa makwinya ndi 40%. Kuonjezera 0.1% -1% ndende ku zodzoladzola kungathandize kusintha photoaging ndi ziphuphu zakumaso zipsera. Mwachitsanzo, zonona za Lancome's Absolue zimagwiritsa ntchito izi ngati chinthu chofunikira kwambiri choletsa kukalamba.

 

3. Kagayidwe Ndi Matenda Adjuvant Chithandizo

Imawongolera lipid metabolism ndikutsitsa cholesterol. Kuyesa kwa nyama kwawonetsa kuti kumatha kuchedwetsa kufalikira kwa chiwindi chamafuta osamwa mowa. Kuphatikiza apo, mu chithandizo cha khansa adjuvant, imawonetsa kufunikira kogwiritsa ntchito poyambitsa chotupa cell apoptosis.
