3-O-Ethyl-L-ascorbic asidhiine huviri huviri hwemafuta ehydrophilic uye yakagadzikana zvakanyanya mumakemikari. 3-O-Ethyl-L-ascorbic acid, cas number 86404-04-8, ine oleophilic uye hydrophilic pfuma sevhitamini C inotorwa, iyo inowedzera chiyero chekushandiswa, kunyanya mumakemikari ezuva nezuva.

Kazhinji vhitamini C yakaoma kubatwa neganda uye ine yakaderera bioavailability. Iyo hydrophilic uye lipophilic properties ye3-O-Ethyl L-ascorbic acid inoita kuti zvive nyore kupinda mu stratum corneum uye kupinda mudermis. Mushure mekupinda muganda, 3-O-Ethyl L-Ascorbic acid inogadziriswa nyore nyore ne biological enzymes kuti iite basa revhitamini C, nokudaro ichivandudza bioavailability yayo.

Mukuwedzera, 3-O-Ethyl-L-ascorbic acid inowanzojairika vhitamini C, iyo inoratidzawo kugadzikana kwepamusoro kuti ive nechokwadi chekuvapo kweVC, uye kunyatsoita mhedzisiro yekuchena uye freckling.

Properties: 3-O-Ethyl-L-ascorbic asidhi chena kana chena crystalline poda pakuonekwa. Icho chimwe chezvakanakisa zvinobva kune vhitamini C kusvika parizvino. Haisi kugadzikana kwemakemikari chete, asiwo ascorbic acid derivative iyo isiri nyore kusvibiswa mushure mekupinda muganda. Inogadziriswa nenzira imwecheteyo sevhitamini C mumuviri, nokudaro ichiita zviri nani mhedzisiro yeascorbic acid.

Mechanism of action: 3-O-Ethyl-L-ascorbic acid inhibits tyrosinase basa uye kuumbwa kwe melanin nekusvika kune basal layer kuburikidza ne stratum corneum yeganda, kuderedza melanin kune isina ruvara, inoshanda mukuchena uye kubvisa freckles. 3-O-Ethyl-L-ascorbic acid inogonawo kutora chikamu zvakananga mukugadzirwa kwe collagen mushure mekupinda mudermis, iyo inowedzera collagen, zvichiita kuti ganda rive rakazara uye rakasununguka.

Mabasa makuru:

(1) Kudzivisa basa re tyrosinase uye kurambidza kuumbwa kwe melanin; Deredza melanin, kurerutsa mavara uye chena.

(2) Yakasimba antioxidant mhedzisiro, inobudirira kubviswa kwemahara radicals.

(3) Kugadzikana kwakanaka, mwenje kuramba, kupisa kupisa, asidhi uye alkali kuramba, mhepo oxidation kuramba. Yakakwira bioavailability, hydrophilic mafuta, nyore kunyudza ganda.

(4) Kudzivirira kuzvimba kweganda kunokonzerwa nechiedza chezuva.

(5) Kurudzira kugadzirwa kwe collagen uye kuwedzera elasticity yeganda.

3-O-Ethyl-L-ascorbic asidhiine basa rekugadzirisa collagen (kusanganisira kugadzirisa collagen kuumbwa uye synthesis), iyo inogona kukurudzira kuumbwa kwemasero eganda uye collagen synthesis maererano nehuwandu hwemasero eganda uye collagen kushandiswa, kuitira kuti ganda rive rinopenya uye elastic. Vitamin C ethyl ether inoshandiswa zvakanyanya mukuchenesa freckle uye anti-kuchembera ganda rekuchengetedza zvigadzirwa, senge lotion, kirimu, toner, mask, essence uye zvichingodaro.

Kushandiswa kwechigadzirwa:

Ichi chigadzirwa chinoshandiswa mukuchena zvigadzirwa, anti-kuchembera zvigadzirwa, mvura, gel, essence, lotion, ganda rekuchengetedza cream uye zvichingodaro.

[Inokurudzirwa chipimo chemushonga] 0.1-2.0%, yakakodzera kuchenera uye kubviswa kwemagetsi zvigadzirwa, kubvisa kuunyana uye anti-kuchembera zvigadzirwa.

[Inokurudzirwa kushanda] Zvakanakisa kushandisa pasi pePH3.0-6.0 mamiriro, uye kuchena uye freckle mhedzisiro ndiyo yakanyanya kunaka.

3-O-ethyl-L-ascorbicasidhi inogona kuva inosimbisa kugadzikana kwep-hydroxyacetophenone mhinduro.

Mhedzisiro yevhitamini C ethyl ether paganda:

Kudzivisa basa re tyrosinase nekuita paCu2 + nekuvhara kuumbwa kwe melanin;

Kuchenesa kwakanyanya uye kubvisa freckle (2% kana yawedzerwa);

Anti kuzvimba kunokonzerwa nechiedza, ine yakasimba antibacterial uye anti-inflammatory effect;

Kuvandudza ganda rakasvibira kupenya, kupa ganda elasticity;

Gadzirisa masero eganda uye kukurudzira kugadzirwa kwe collagen.
