3-O-Ethyl-L-ascorbic acidine hunhu huviri hwemafuta anonyungudika mumvura uye yakagadzikana zvakanyanya pamakemikari. 3-O-Ethyl-L-ascorbic acid, cas nhamba 86404-04-8, ine hunhu hwe oleophilic uye hydrophilic semusanganiswa wevhitamini C, iyo inowedzera kushanda kwayo, kunyanya mumakemikari ezuva nezuva.

Vhitamini C yakajairika inonetsa kunyudzwa neganda uye haina bioavailability yakawanda. Hunhu hwe3-O-Ethyl L-ascorbic acid hunoita kuti zvive nyore kupinda mu stratum corneum uye kupinda mu dermis. Mushure mekupinda muganda, 3-O-Ethyl L-Ascorbic acid inoora nyore nyore nema enzymes e biological kuti iite basa revhitamini C, nokudaro ichivandudza bioavailability yayo.

Pamusoro pezvo, 3-O-Ethyl-L-ascorbic acid ivhitamini C yakajairika, iyo inoratidzawo kugadzikana kwakanyanya kuve nechokwadi chekuwanikwa kweVC, uye inoita kuti ganda rive jena uye rima.

Hunhu: 3-O-Ethyl-L-ascorbic acid ipurasitiki chena kana chena inotaridzika seye crystalline powder. Ndiyo imwe yemhando dzakanakisisa dzevhitamini C kusvika pari zvino. Haingori chete yakasimba pamakemikari, asiwo inokonzerwa ne ascorbic acid isingachinji ruvara nyore kana yapinda muganda. Inogayiwa mumuviri nenzira imwecheteyo nevhitamini C, nokudaro ichiita kuti ascorbic acid ive nani.

Maitiro ekushanda: 3-O-Ethyl-L-ascorbic acid inodzivirira tyrosinase activity uye kuumbwa kwemelanin nekusvika pabasal layer kuburikidza ne stratum corneum yeganda, zvichiita kuti melanin isave neruvara, inoshanda mukuchenesa nekubvisa mavanga. 3-O-Ethyl-L-ascorbic acid inogonawo kutora chikamu zvakananga mukugadzirwa kwe collagen mushure mekupinda mu dermis, izvo zvinowedzera collagen, nokudaro zvichiita kuti ganda rive rakazara uye rakapfava.

Mabasa makuru:

(1) Kudzivisa kushanda kwetyrosinase uye kudzivirira kuumbwa kwemelanin; Kuderedza melanin, kujekesa mavara uye kuchena.

(2) Simba guru rekudzivirira muviri, kubvisa zvinobudirira mafree radicals.

(3) Kugadzikana kwakanaka, kuramba chiedza, kuramba kupisa, kuramba acid nealkali, kuramba mhepo ine oxidation. Kuwanikwa kwakanyanya kwebioavailability, mafuta anonyungudika mumvura, nyore kunwa ganda.

(4) Dzivisa kuzvimba kweganda kunokonzerwa nezuva.

(5) Kukurudzira kugadzirwa kwecollagen uye kuwedzera kusimba kweganda.

3-O-Ethyl-L-ascorbic acidine basa rekugadzirisa collagen (kusanganisira kugadzirisa kuumbwa kwecollagen uye synthesis), izvo zvinogona kukurudzira kuumbwa kwemasero eganda uye synthesis yecollagen zvichienderana nehuwandu hwemasero eganda uye kushandiswa kwecollagen, kuitira kuti ganda ripenye uye rive nyore. Vitamin C ethyl ether inoshandiswa zvakanyanya mukuchenesa ganda uye mishonga yekudzivirira kukwegura, senge lotion, cream, toner, mask, essence nezvimwewo.

Kushandiswa kwechigadzirwa:

Chigadzirwa ichi chinoshandiswa muzvigadzirwa zvekuchenesa, zvigadzirwa zvekudzivirira kukwegura, mvura, gel, essence, lotion, kirimu yekuchengetedza ganda nezvimwewo.

[Chipimo chinokurudzirwa] 0.1-2.0%, chakakodzera zvigadzirwa zvekuchenesa uye kubvisa mavanga, kubvisa makwinya uye zvigadzirwa zvekudzivirira kukwegura.

[Kushandiswa kunokurudzirwa] Zviri nani kushandisa pasi pemamiriro ezvinhu ePH3.0-6.0, uye mhedzisiro yekuchena uye freckle ndiyo yakanakisa.

3-O-ethyl-L-ascorbicasidhi inogona kubatsira mukugadzirisa mhinduro dzep-hydroxyacetophenone.

Mhedzisiro yevhitamini C ethyl ether paganda:

Kudzivisa kushanda kwetyrosinase nekushanda paCu2+ uye kudzivirira kuumbwa kwemelanin;

Kuchenesa uye kubvisa mavanga kunoshanda zvikuru (2% kana zvawedzerwa);

Kudzivirira kuzvimba kunokonzerwa nechiedza, kune simba guru rekurwisa mabhakitiriya uye rekudzivirira kuzvimba;

Kuvandudza kupenya kweganda, kuita kuti ganda rive nyore;

Gadzirisa mashandiro emasero eganda uye kusimudzira kugadzirwa kwecollagen.
