3-O-Ethyl-L-ascorbic acidmuaj ob lub zog ntawm hydrophilic roj thiab yog tshuaj lom neeg ruaj khov. 3-O-Ethyl-L-ascorbic acid, cas naj npawb 86404-04-8, muaj oleophilic thiab hydrophilic khoom raws li ib tug vitamin C derivative, uas ncua nws cov Scope ntawm daim ntawv thov, tshwj xeeb tshaj yog nyob rau hauv niaj hnub chemistry.

Ordinary vitamin C yog ib qho nyuaj rau absorbed los ntawm daim tawv nqaij thiab muaj tsawg bioavailability. Lub hydrophilic thiab lipophilic zog ntawm 3-O-Ethyl L-ascorbic acid ua rau nws yooj yim rau nkag mus rau hauv lub stratum corneum thiab nkag mus rau lub dermis. Tom qab nkag mus rau ntawm daim tawv nqaij, 3-O-Ethyl L-Ascorbic acid yog yooj yim decomposed los ntawm cov enzymes lom neeg ua si lub luag hauj lwm ntawm vitamin C, yog li txhim kho nws bioavailability.

Tsis tas li ntawd, 3-O-Ethyl-L-ascorbic acid yog cov vitamin C, uas kuj qhia tau hais tias muaj kev ruaj ntseg kom ntseeg tau tias muaj VC, thiab ua tiav cov txiaj ntsig ntawm whitening thiab freckling.

Khoom: 3-O-Ethyl-L-ascorbic acid yog dawb los yog dawb crystalline hmoov nyob rau hauv tsos. Nws yog ib qho zoo tshaj plaws derivatives ntawm vitamin C rau hnub tim. Nws tsis yog tsuas yog tshuaj lom neeg ruaj khov, tab sis kuj yog ascorbic acid derivative uas tsis yooj yim discolored tom qab nkag mus rau ntawm daim tawv nqaij. Nws yog metabolized tib yam li vitamin C hauv lub cev, yog li ua kom muaj txiaj ntsig zoo ntawm ascorbic acid.

Mechanism ntawm kev txiav txim: 3-O-Ethyl-L-ascorbic acid inhibits tyrosinase kev ua si thiab tsim ntawm melanin los ntawm ncav lub basal txheej los ntawm stratum corneum ntawm daim tawv nqaij, txo melanin kom tsis muaj xim, zoo nyob rau hauv whitening thiab tshem tawm freckles. 3-O-Ethyl-L-ascorbic acid kuj tuaj yeem koom ncaj qha rau hauv kev sib txuas ntawm collagen tom qab nkag mus rau hauv lub dermis, uas ua rau kom collagen, yog li ua rau daim tawv nqaij puv thiab elastic.

Lub luag haujlwm tseem ceeb:

(1) Inhibiting tyrosinase kev ua si thiab inhibiting melanin tsim; Txo melanin, lighten me ntsis thiab whiten.

(2) Cov nyhuv antioxidant muaj zog, tshem tawm cov dawb radicals.

(3) Zoo stability, lub teeb tsis kam, kub tsis kam, acid thiab alkali tsis kam, huab cua oxidation kuj. High bioavailability, hydrophilic roj, yooj yim nqus ntawm daim tawv nqaij.

(4) Tiv thaiv daim tawv nqaij mob los ntawm tshav ntuj.

(5) Txhawb nqa collagen ntau lawm thiab ua kom tawv nqaij elasticity.

3-O-Ethyl-L-ascorbic acidmuaj cov haujlwm ntawm kev kho collagen (xws li kho collagen muaj pes tsawg leeg thiab synthesis), uas tuaj yeem txhawb kev tsim ntawm cov tawv nqaij hlwb thiab collagen synthesis raws li qhov piv ntawm daim tawv nqaij thiab collagen noj, thiaj li ua rau daim tawv nqaij ci thiab elastic. Vitamin C ethyl ether yog dav siv nyob rau hauv whitening freckle thiab anti-aging ntawm daim tawv nqaij cov khoom, xws li tshuaj pleev ib ce, cream, toner, daim npog qhov ncauj, essence thiab hais txog.

Khoom siv:

Cov khoom no yog siv rau hauv cov khoom siv ntxuav hniav dawb, cov khoom siv los tiv thaiv kev laus, dej, gel, essence, lotion, tshuaj pleev ib ce thiab lwm yam.

[pom pom zoo] 0.1-2.0%, haum rau cov khoom siv ntxuav hniav dawb thiab freckle tshem tawm, wrinkle tshem tawm thiab cov khoom tiv thaiv kev laus.

[Cov haujlwm pom zoo] Nws yog qhov zoo tshaj plaws los siv nyob rau hauv PH3.0-6.0 cov xwm txheej, thiab cov nyhuv whitening thiab freckle yog qhov zoo tshaj plaws.

3-O-ethyl-L-ascorbicacid tej zaum yuav yog ib qho tseem ceeb stabilizer rau p-hydroxyacetophenone daws.

Cov teebmeem ntawm vitamin C ethyl ether rau ntawm daim tawv nqaij:

Inhibiting tyrosinase kev ua si los ntawm kev ua ntawm Cu2 + thiab thaiv kev tsim melanin;

Zoo heev whitening thiab freckle tshem tawm (2% thaum ntxiv);

Anti-inflammatory tshwm sim los ntawm lub teeb, muaj zog antibacterial thiab anti-inflammatory nyhuv;
