3-O-Ethyl-L-ascorbic acidnwere ihe abụọ dị na mmanụ hydrophilic ma ọ kwụsiri ike nke ukwuu n'ụzọ kemịkalụ. 3-O-Ethyl-L-ascorbic acid, nọmba cas 86404-04-8, nwere ihe onwunwe oleophilic na hydrophilic dị ka ihe sitere na vitamin C, nke na-agbatịkwu ojiji ya, ọkachasị na kemịkalụ kwa ụbọchị.

Ọ na-esiri ike ịmịkọrọ vitamin C nkịtị site na akpụkpọ ahụ, ọ na-enwekwa obere bioavailability. Njirimara hydrophilic na lipophilic nke 3-O-Ethyl L-ascorbic acid na-eme ka ọ dịrị mfe ịbanye na stratum corneum ma banye na dermis. Mgbe ọ banyere n'ime akpụkpọ ahụ, enzyme bayọlọji na-agbaze ngwa ngwa site na enzymes bayọlọji iji rụọ ọrụ nke vitamin C, si otú a na-eme ka bioavailability ya ka mma.

Tinyere nke ahụ, 3-O-Ethyl-L-ascorbic acid bụ vitamin C a na-ahụkarị, nke na-egosikwa nkwụsi ike dị elu iji hụ na VC dị, ma nweta mmetụta nke ịcha ọcha na ntụpọ.

Àgwà: 3-O-Ethyl-L-ascorbic acid bụ ntụ ọcha ma ọ bụ ọcha kristal n'ọdịdị ya. Ọ bụ otu n'ime ihe ndị kacha mma sitere na vitamin C ruo taa. Ọ bụghị naanị na ọ kwụsiri ike na kemịkalụ, kamakwa ọ bụ ihe sitere na ascorbic acid nke na-adịghị agbanwe agba ngwa ngwa mgbe ọ banyere n'akpụkpọ ahụ. A na-agbanwe ya n'otu ụzọ ahụ vitamin C si arụ ọrụ n'ahụ, si otú a na-eme ka ascorbic acid dịkwuo mma.

Usoro ọrụ: 3-O-Ethyl-L-ascorbic acid na-egbochi ọrụ tyrosinase na mmepụta melanin site na iru akwa basal site na stratum corneum nke akpụkpọ ahụ, na-ebelata melanin ka ọ bụrụ nke na-enweghị agba, na-arụ ọrụ nke ọma n'ịcha ọcha na iwepụ ntụpọ. 3-O-Ethyl-L-ascorbic acid nwekwara ike isonye ozugbo na mmepụta nke collagen mgbe ọ banyere na dermis, nke na-eme ka collagen dịkwuo elu, si otú a na-eme ka akpụkpọ ahụ jupụta ma na-agbanwe agbanwe.

Isi ọrụ:

(1) Ịgbochi ọrụ tyrosinase na igbochi mmepụta melanin; Belata melanin, mee ka ntụpọ dị nro ma mee ka ọ acha ọcha.

(2) Mmetụta antioxidant siri ike, iwepụ ihe ndị na-emebi ihe n'efu.

(3) Ịkwụsi ike nke ọma, iguzogide ìhè, iguzogide okpomọkụ, iguzogide acid na alkali, iguzogide oxidation ikuku. Enwere ike inweta bioavailability dị elu, mmanụ hydrophilic, na-amịkọrọ akpụkpọ ahụ ngwa ngwa.

(4) Gbochie mbufụt akpụkpọ ahụ nke anwụ na-acha.

(5) Na-akwalite mmepụta collagen ma na-eme ka akpụkpọ ahụ na-agbanwe agbanwe.

3-O-Ethyl-L-ascorbic acidnwere ọrụ nke ịrụzi collagen (gụnyere ịrụzi nhazi na njikọta collagen), nke nwere ike ịkwalite mmepụta nke mkpụrụ ndụ akpụkpọ ahụ na njikọta collagen dịka oke nke mkpụrụ ndụ akpụkpọ ahụ na oriri collagen si dị, ka akpụkpọ ahụ wee na-egbuke egbuke ma na-agbanwe agbanwe. A na-eji Vitamin C ethyl ether eme ihe nke ukwuu na ngwaahịa nlekọta akpụkpọ ahụ na-eme ka freckle dị ọcha na nke na-egbochi ịka nká, dịka ude mmiri, ude, toner, ihe mkpuchi ihu, ihe na-eme ka akpụkpọ ahụ dị ọcha na ihe ndị ọzọ.

Ojiji ngwaahịa:

A na-eji ngwaahịa a eme ihe n'ihe gbasara ịcha ọcha, ihe ndị na-egbochi ịka nká, mmiri, gel, ihe dị mkpa, ude mmiri, ude nlekọta akpụkpọ ahụ na ihe ndị ọzọ.

[Ọnụọgụ akwadoro] 0.1-2.0%, ọ dị mma maka ngwaahịa na-eme ka ọcha na iwepụ freckle, iwepụ wrinkles na ngwaahịa na-egbochi ịka nká.

[Ọrụ akwadoro] Ọ kacha mma iji ya n'okpuru ọnọdụ PH3.0-6.0, mmetụta ọcha na freckle kacha mma.

3-O-ethyl-L-ascorbicacid nwere ike ịbụ ihe na-eme ka ihe kwụsie ike bara uru maka ngwọta p-hydroxyacetophenone.

Mmetụta nke vitamin C ethyl ether na akpụkpọ ahụ:

Ịkwụsị ọrụ tyrosinase site n'iji Cu2+ mee ihe ma gbochie mmepụta melanin;

Mwepụ ọcha na freckle dị irè nke ukwuu (2% mgbe etinyere ya);

Mgbochi mbufụt nke ìhè kpatara, nwere mmetụta siri ike nke nje bacteria na mgbochi mkpali;

Mee ka akpụkpọ ahụ dị mma, mee ka akpụkpọ ahụ na-agbanwe agbanwe;

Mezie ọrụ mkpụrụ ndụ akpụkpọ ahụ ma kwalite mmepụta collagen.
