Iyini i-Vitamin A Palmitate?
I-Vitamin A Palmitate / Retinyl Palmitate iwuhlobo lukavithamini A (VitaminA).Yaziwa nangokuthi i-retinol, iyingxenye ebalulekile yamangqamuzana abonakalayo. Iyisakhi esibalulekile sezinto eziphilayo eziyinkimbinkimbi. Ingahlakazwa ku-matrix ye-gelatin noma uwoyela. Izwela ukukhanya nomoya. I-butylated hydroxytoluene (BHT) kanye ne-butylated hydroxyanisole (BHA) kuvame ukufakwa njengeziqinisi. Incibilika ku-ethanol, i-chloroform, i-acetone ne-ester kawoyela, indawo encibilikayo engu-28~29°C. I-Retinyl palmitate iyingxenye yezakhi ezibizwa ngokuthi ama-retinoids, afana ngamakhemikhali ne-vitamin A. Ibonisa umphumela onenzuzo embonweni, esikhumbeni nasemzimbeni wokuzivikela komzimba. , ivimbela ukwanda kwamangqamuzana futhi ivimbele umdlavuza. Iwukudla okubalulekile kanye nenhlanganisela yokwelapha.
Umsebenzi we-Vitamin A Palmitate
I-Vitamin A Palmitate ingamuncwa esikhunjeni, imelane ne-keratinization, ikhuthaze ukukhula kwe-collagen ne-elastin, futhi yandise ukushuba kwe-epidermis nedermis. Thuthukisa ukunwebeka kwesikhumba, uqede ngempumelelo imibimbi, ukhuthaze ukuvuselelwa kwesikhumba futhi ugcine ubungqabavu besikhumba. , Ukhilimu othambisayo, ukhilimu wokukhanda, ishampoo, i-conditioner, isiza ukuthuthukisa ukungatheleleki, ithuthukise ukukhula, iqinise amathambo, njll.
Ukusetshenziswa kwe-Vitamin A Palmitate
I-Vitamin A Palmitate yaziwa ngokuthi "i-normalizer" yesikhumba. Isebenza njenge-antikeratinizing ejenti, isiza isikhumba ukuthi sihlale sithambile futhi sigcwele, futhi sithuthukise izakhiwo zaso zokuvimbela amanzi. Ngenxa yethonya layo esikhunjeni sokuvimbela amanzi, iwusizo ekomeni, ekushiseni nasekungcoleni. Futhi iyi-anti-oxidant futhi iyaphakanyiswa ukuthi isetshenziswe kuma-sunscreens. Ucwaningo lwezokwelapha nge-vitamin A Palmitate lukhombisa ushintsho olukhulu ekwakhekeni kwesikhumba, nokwanda kwe-collagen, i-DNA, ukujiya kwesikhumba, nokunwebeka. Ukuzinza kwe-Vitamin A Palmitate kuphakeme kune-retinol.
I-Retinyl palmitate iyi-conditioner yesikhumba. Le retinoid ithathwa njengenguqulo ethambile ye-retinoic acid, uma kubhekwa izakhiwo zayo zokuguqula. kanye esikhumbeni, iguqulela ku-retinol, yona iguqule ku-retinoic acid. Ngokwe-Physiologically, kuthiwa ngokwanda kwe-R epidermal ukujiya, okukhuthaza ukukhiqizwa kwamaprotheni e-epidermal engeziwe, nokwandisa ukunwebeka kwesikhumba. Ngokwezimonyo, i-retinyl palmitate isetshenziselwa ukunciphisa inani nokujula kwemigqa emincane nemibimbi, futhi ivimbele ukuhwalala kwesikhumba okubangelwa ukuchayeka kwe-UV. Ukusabela okwesibili okufana ne-erythema, ukoma, noma ukucasuka akuhlotshaniswa ne-retinyl palmitate. Isebenza kahle kakhulu uma isetshenziswa ihlanganiswe ne-glycolic acid ngoba ifinyelela ukungena okukhulu. E-United States, izinga layo eliphezulu lokusetshenziswa ekwenziweni kwezimonyo lingamaphesenti angu-2. I-Retinyl palmitate iyi-ester ye-retinol ne-palmitic acid.
