Vitamine A Palmitate ni iki?
Vitamine A Palmitate / Retinyl Palmitate ni ubwoko bwa vitamine A (VitamineA) .Bizwi kandi nka retinol, ni ikintu cy'ingenzi kigize ingirabuzimafatizo. Nintungamubiri yingenzi yibinyabuzima bigoye. Irashobora gukwirakwizwa muri materix ya gelatine cyangwa amavuta. Yumva urumuri n'umwuka. Hydroxytoluene ya Butylated (BHT) na hydroxyanisole ya butylated (BHA) ikunze gushyirwaho nka stabilisateur. Gushonga muri Ethanol, chloroform, acetone na ester yamavuta, gushonga 28 ~ 29 ° C.Retinyl palmitate ni mubyiciro byimvange bita retinoide, bisa na vitamine A. Byerekana ingaruka nziza mubyerekezo, kuruhu no mumikorere yumubiri. , ibuza ikwirakwizwa ry'uturemangingo kandi ikarinda kanseri. Nibyokurya byingenzi kimwe nubuvuzi.
Imikorere ya Vitamine A.
Vitamine A Palmitate irashobora kwinjizwa mu ruhu, ikarwanya keratinisation, igatera imikurire ya kolagen na elastine, kandi ikongera umubyimba wa epidermis na dermis. Kongera uruhu rworoshye, kurandura neza inkari, guteza imbere uruhu no gukomeza ubuzima bwuruhu. Amavuta yo kwisiga, gusana amavuta, shampoo, kondereti, bifasha kuzamura ubudahangarwa, guteza imbere iterambere, gushimangira amagufwa, nibindi
Gukoresha Vitamine A.
Vitamine A Palmitite izwi nk'uruhu “usanzwe.” Ikora nk'imiti igabanya ubukana, ifasha uruhu kuguma rworoshye kandi rusukuye, no kunoza imiterere-y’amazi. Kubera ingaruka bigira ku miterere-y’amazi y’uruhu, ni ingirakamaro mu kurwanya umwuma, ubushyuhe, n’umwanda. Ni anti-okiside kandi irasabwa gukoreshwa mu zuba. Ubushakashatsi bwa Clinical hamwe na vitamine A Palmitate yerekana impinduka zikomeye mubigize uruhu, hamwe no kwiyongera kwa kolagen, ADN, umubyimba wuruhu, hamwe na elastique. Vitamine A Palmitate ihagaze neza iruta retinol.
Retinyl palmitate ni kondereti y'uruhu. Iyi retinoide ifatwa nka verisiyo yoroheje ya aside retinoque, ukurikije imiterere yayo. rimwe ku ruhu, ihinduka retinol, nayo igahinduka aside aside. Mu buryo bwa Physiologique, ishimirwa kongera ubwiyongere bwa epidermal R, itera umusaruro wa poroteyine nyinshi, kandi byongera uruhu rworoshye. Kwisiga, retinyl palmitate ikoreshwa mukugabanya umubare nuburebure bwimirongo myiza niminkanyari, kandi bikarinda ububobere bwuruhu buturuka kuri uV guhura. Icyiciro cya kabiri nka erythma, gukama, cyangwa kurakara ntabwo bifitanye isano na retinyl palmitate. Ndetse nibyiza cyane iyo bikoreshejwe hamwe na acide glycolike kuko igera cyane. Muri Reta zunzubumwe, urwego ntarengwa rwo gukoresha mu kwisiga ni 2 ku ijana. Retinyl palmitate ni ester ya retinol na aside palmitike.
