3-O-Ethyl-L-aside asideifite ibintu bibiri byamavuta ya hydrophilique kandi ni chimique ihagaze neza cyane. 3-O-Ethyl-L-ascorbic aside, cas nomero 86404-04-8, ifite umutungo wa oleophilique na hydrophilique nkibikomoka kuri vitamine C, ikagura uburyo ikoreshwa cyane cyane muri chimie ya buri munsi.

Vitamine C isanzwe iragoye kwinjizwa nuruhu kandi ifite bioavailable nke. Indwara ya hydrophilique na lipofilique ya 3-O-Ethyl L-ascorbic aside byoroha kwinjira muri stratum corneum no kwinjira muri dermis. Nyuma yo kwinjira mu ruhu, 3-O-Ethyl L-Ascorbic aside yangirika byoroshye na enzymes biologique kugirango igire uruhare rwa vitamine C, bityo itume bioavailability iboneka.

Byongeye kandi, 3-O-Ethyl-L-ascorbic aside ikunze kuba vitamine C, nayo igaragaza ituze ryinshi kugirango VC iboneke, kandi rwose igere ku ngaruka zo kwera no kuvunika.

Ibyiza: 3-O-Ethyl-L-ascorbic acide ni ifu yera cyangwa yera ya kirisiti ya kirisiti. Nimwe mubikomoka kuri vitamine C kugeza ubu. Ntabwo ihagaze neza gusa, ahubwo ikomoka kuri acide acorbike idashobora guhinduka ibara nyuma yo kwinjira muruhu. Ihinduranya kimwe na vitamine C mu mubiri, bityo ikagira ingaruka nziza ya acide acorbike.

Uburyo bwibikorwa: 3-O-Ethyl-L-ascorbic acide ibuza ibikorwa bya tyrosinase no gukora melanin igera kumurongo wibanze unyuze muri stratum corneum yuruhu, kugabanya melanin ibara ritagira ibara, bigira umumaro mukwera no gukuraho ibibyimba. 3-O-Ethyl-L-ascorbic aside irashobora kandi kugira uruhare rutaziguye muri synthesis ya kolagen nyuma yo kwinjira muri dermis, ikongera kolagen, bityo uruhu rwuzuye kandi rworoshye.

Ibikorwa by'ingenzi:

(1) Kubuza ibikorwa bya tyrosinase no kubuza gukora melanin; Mugabanye melanin, koroshya ibibara no kwera.

(2) Ingaruka ikomeye ya antioxydeant, gukuraho neza radicals yubusa.

(3) Guhagarara neza, kurwanya urumuri, kurwanya ubushyuhe, aside na alkali, kurwanya umwuka wa okiside. Bioavailable nyinshi, amavuta ya hydrophilique, kwinjiza uruhu byoroshye.

(4) Irinde gutwika uruhu ruterwa nizuba.

(5) Guteza imbere umusaruro wa kolagen no kongera ubworoherane bwuruhu.

3-O-Ethyl-L-aside asideifite ibikorwa byo gusana kolagen (harimo no gusana ibice bya kolagen hamwe na synthesis), bishobora guteza imbere ishingwa ryingirangingo zuruhu hamwe na synthesis ya kolagen ukurikije igipimo cyingirangingo zuruhu hamwe nogukoresha kolagen, kugirango uruhu rukayangane kandi rworoshye. Vitamine C Ethyl ether ikoreshwa cyane mugutunganya ibara ryera no kurwanya gusaza ibicuruzwa byita kuruhu, nka amavuta yo kwisiga, cream, toner, mask, essence nibindi.

Gukoresha ibicuruzwa:

Iki gicuruzwa gikoreshwa mubicuruzwa byera, ibicuruzwa birwanya gusaza, amazi, gel, essence, amavuta yo kwisiga, cream yita kuruhu nibindi.

.

[Igikorwa gisabwa] Nibyiza gukoresha mugihe cya PH3.0-6.0, kandi ingaruka zo kwera na freckle nibyiza.

3-O-Ethyl-L-ascorbicaside irashobora kuba stabilisateur yingirakamaro kuri p-hydroxyacetophenone ibisubizo.

Ingaruka za vitamine C Ethyl ether kuruhu:

Kubuza ibikorwa bya tyrosinase ukora kuri Cu2 + no guhagarika melanin;

Gukuraho neza cyane no gukuraho frake (2% iyo byongeweho);

Kurwanya umuriro biterwa n'umucyo, bifite antibacterial ikomeye na anti-inflammatory;

Kunoza uruhu rwijimye, tanga uruhu rworoshye;

Gusana ibikorwa byuruhu rwuruhu no guteza imbere umusaruro wa kolagen.
