aside ascorbic ya 3-O-Ethyl-Lifite imiterere ibiri y’amavuta akunda amazi kandi irahindagurika cyane mu buryo bwa shimi. 3-O-Ethyl-L-ascorbic acid, cas nomero 86404-04-8, ifite imiterere ikunda oleophilic na hydrophilic nk'ikintu kiva kuri vitamine C, bituma ikoreshwa cyane, cyane cyane mu butabire bwa buri munsi.

Vitamine C isanzwe iragoye kwinjiza mu ruhu kandi ifite ubushobozi buke bwo kwinjiriramo. Imiterere ya aside 3-O-Ethyl L-ascorbic ifasha mu kunyura mu mazi no mu gushonga kw'ibinure ituma byoroha kwinjira mu gice cy'umubiri no kwinjira mu ruhu. Nyuma yo kwinjira mu ruhu, aside 3-O-Ethyl L-Ascorbic ibora byoroshye na enzymes za biological kugira ngo igire uruhare rwa vitamine C, bityo bikongera ubushobozi bwayo bwo kwinjiriramo.

Byongeye kandi, aside 3-O-Ethyl-L-ascorbic ni vitamine C isanzwe, ikaba inagaragaza ko ihamye cyane kugira ngo VC iboneke, kandi ikagera ku ngaruka zo kwera no kumera nk'amabara.

Imiterere: Aside ascorbic 3-O-Ethyl-L-ni ifu y'umweru cyangwa umweru isa na crystalline. Ni imwe mu ngaruka nziza za vitamine C kugeza ubu. Ntabwo ihinduka gusa mu buryo bwa shimi, ahubwo ni n'iy'aside ascorbic idahinduka ibara byoroshye iyo igeze mu ruhu. Ihinduka nk'uko vitamine C ihinduka mu mubiri, bityo ikagira ingaruka nziza kuri aside ascorbic.

Uburyo ikora: aside 3-O-Ethyl-L-ascorbic ibuza imikorere ya tyrosinase no gukora kwa melanin igera ku gice cyo hasi cy'uruhu binyuze mu gice cya corneum y'uruhu, ikagabanya melanin itagira ibara, ikagira uruhare mu kwera no gukuraho uduce duto. aside 3-O-Ethyl-L-ascorbic ishobora kandi kugira uruhare rutaziguye mu gukora kolajeni nyuma yo kwinjira muri dermis, ibyo bigatuma kolajeni yongera, bityo bigatuma uruhu rwuzura kandi rugakomera.

Imirimo y'ingenzi:

(1) Kubuza imikorere ya tyrosinase no kubuza ikorwa rya melanin; Kugabanya melanin, gusohora utudomo no kwera.

(2) Ingaruka zikomeye ku irwanya ry’umubiri, ikavanaho neza imisemburo y’ubudahangarwa.

(3) Ituza neza, irwanya urumuri, irwanya ubushyuhe, irwanya aside na alkali, irwanya ogisijeni y'umwuka. Iboneka cyane mu mubiri, amavuta akunda amazi, uruhu rworoshye kwinjiza.

(4) Irinde ubushyuhe bw'uruhu buterwa n'izuba.

(5) Guteza imbere ikorwa rya kolajeni no kongera ubushobozi bw'uruhu.

aside ascorbic ya 3-O-Ethyl-LIfite imikorere yo gusana kolajeni (harimo no gusana imiterere ya kolajeni n'ikorwa ryayo), ishobora guteza imbere ikorwa ry'uturemangingo tw'uruhu no gukora kolajeni hakurikijwe igipimo cy'uturemangingo tw'uruhu n'ikoreshwa rya kolajeni, kugira ngo uruhu rubengerane kandi rube rworoshye. Vitamine C ethyl ether ikoreshwa cyane mu gutunganya uruhu rwera kandi rurwanya gusaza, nka lotion, cream, toner, mask, essence n'ibindi.

Ikoreshwa ry'ibicuruzwa:

Iki gicuruzwa gikoreshwa mu bintu bisukura uruhu, imiti irwanya gusaza, amazi, gel, essence, amavuta yo kwisiga, amavuta yo kwisiga uruhu n'ibindi.

[Igipimo gisabwa] 0.1-2.0%, gikwiriye gukoreshwa mu gusiga umweru no gukuraho uduce duto, gukuraho iminkanyari no kurwanya gusaza.

[Ibikorwa bisabwe] Ni byiza kuyikoresha mu gihe cya PH3.0-6.0, kandi ingaruka zo kwera no gucika kw'amabara ni zo nziza cyane.

3-O-ethyl-L-ascorbicaside ishobora kuba ingirakamaro mu gushimangira imisemburo ya p-hydroxyacetophenone.

Ingaruka za Vitamine C ethyl ether ku ruhu:

Kubuza imikorere ya tyrosinase binyuze mu gukora kuri Cu2+ no kubuza ikorwa rya melanin;

Gukuraho amabara y'uruhu neza cyane no kuyakuraho neza (2% iyo yongewemo);

Kurwanya ubushyuhe buterwa n'urumuri, bifite ingaruka zikomeye zo kurwanya udukoko two mu bwoko bwa bagiteri n'ubushyuhe;

Kunoza uruhu kugira ngo rube rudasobanutse neza, biruhe uruhu rworoshye;

Gusana imikorere y'uturemangingo tw'uruhu no guteza imbere ikorwa rya kolajeni.
