Vitamin A Acetate: Anti-Kukwegura Ingredient yeNutritional Supplements uye Cosmetics

●Chii Vitamin A Acetate?

Retinyl Acetate, chemikemikari zita retinol acetate, molecular formula C22H30O3, CAS nhamba 127-47-9, inotorwa esterified yevhitamini A. Inofananidzwa nevhitamini A doro, inowedzera kugadzikana kuburikidza ne esterification reaction uye inodzivisa kuora kwe oxidative, kuva chinhu chinokosha chakasvibiswa mumishonga uye cosmetics.

 

vhitamini A yakasikwa inonyanya kuwanikwa muchiropa chemhuka nehove, asi kugadzirwa kwemaindasitiri kunonyanya kutora kemikari synthesis, sekushandisa β-ionone seyakatangira uye kuigadzira kuburikidza neWittig condensation reaction. Mumakore achangopfuura, tekinoroji yekugadzira yakasvibirira senge ultrasound-enhanced interfacial enzyme catalysis yakabuda, zvakanyanya kuvandudza maitiro ekuita uye kuderedza kusvibiswa, ikava danho rakakosha rekusimudzira tekinoroji.

 

Vitamin A acetateivhu jena kusvika kuchiedza checrystalline poda kana viscous fluid ine 57-58 ° C, inovira inosvika 440.5 ° C, density ye1.019 g/cm³, uye refractive index ye1.547-1.555. Iine akakosha kunyungudika kwemafuta uye inonyungudika zviri nyore muorganic solvents senge ethanol uye ether, asi ine kushomeka kwemvura kunyungudika, uye inoda kuve microencapsulated kuti ivandudze dispersibility yayo muchikafu.

 

Mukutaura kwekugadzikana, vitamin A acetate inobata chiedza, kupisa uye oksijeni, uye inoda kuchengetwa kure nechiedza (2-8 ° C), uye antioxidants yakadai seBHT inowedzerwa kuwedzera hupenyu hwesherufu. Yayo bioavailability yakakwira se80% -90%, uye inoshandurwa kuita retinol ne enzymatic hydrolysis mumuviri uye inotora chikamu mune physiological metabolism.

 

● Ndezvipi ZvakanakiraVitamin A Acetate?

1. Kuona Uye Kudzora Kudzivirira Kwemuviri

Seyakashanda fomu yevhitamini A, inotora chikamu mukuumbwa kwechiratidzo nekushandura kune retinal, kudzivirira hupofu hwehusiku uye chirwere chemaziso chakaoma. Panguva imwecheteyo, inowedzera basa rekuvhara kwemasero epithelial uye inoderedza ngozi yehutachiona hwekufema. Miedzo yemakiriniki yakaratidza kuti inogona kuvandudza kudzivirira kwevana ne30%.

 

2. Ganda Anti-Kukwegura Uye Kugadzirisa

Inodzivisa kuwandisa kwekuwedzera kwe keratinocytes, inosimudzira collagen synthesis, uye inoderedza kudzika kwekukwenya ne40%. Kuwedzera 0.1% -1% yekumisikidza kune zvizorwa kunogona kuvandudza mapikicha uye mavanga echuru. Semuyenzaniso, Lancome's Absolue akatevedzana cream inoshandisa iyi seyakakosha yekudzivirira kuchembera.

 

3. Metabolism Uye Chirwere Adjuvant Treatment

Inogadzirisa lipid metabolism uye inoderedza cholesterol mazinga. Kuedza kwemhuka kwakaratidza kuti inogona kunonoka kufambira mberi kwechirwere chisingaiti chiropa chechiropa. Uye zvakare, mukurapwa kwegomarara adjuvant, inoratidza kukosha kwekushandisa nekukurudzira tumor cell apoptosis.
