Qhov sib txawv tseem ceeb ntawm salicylic acid thiab hyaluronic acid yog salicylic acid yog ib yam khoom monomeric, hos hyaluronic acid yog ib yam khoom polymeric. Ntxiv mus, daim ntawv thov-ntseeg, salicylic acid yog siv los ua tshuaj kho pob txuv, dandruff, pob txuv thiab lwm yam kab mob ntawm daim tawv nqaij. Meanwhile, hyaluronic acid yog siv nyob rau hauv lub cosmetic kev lag luam raws li ib tug tshwm sim nyob rau hauv cov khoom siv tu tawv nqaij.
Peb tuaj yeem hu ua salicylic acid ua ib lub molecule, tab sis hyaluronic acid muaj ntau tshaj ib chav tsev sib txuas los ntawm kev sib txuas. Yog li ntawd, peb tuaj yeem hu nws ua cov tshuaj polymeric.
YSalicylic Acid yog dab tsi?
Salicylic acid yog ib qho organic compound uas tseem ceeb heev raws li cov tshuaj uas pab tshem tawm txheej txheej ntawm daim tawv nqaij. Cov khoom no zoo li tsis muaj xim rau dawb crystalline khoom uas tsis muaj ntxhiab tsw. Cov tshuaj formula ntawm no compound yog C7H6O3, thiab molar loj yog 138.12 g / mol. Lub melting point ntawm salicylic acid crystals yog 158.6 ° C, thiab decomposes ntawm 200 ° C. Cov muaju no tuaj yeem ua rau sublimation ntawm 76 ° C (sublimation yog hloov dua siab tshiab ntawm cov khoom ncaj qha mus rau nws cov theem vapor yam tsis tau mus txog theem ua kua). Lub npe IUPAC ntawm salicylic acid yog 2-Hydroxybenzoic acid.
Daim duab 01: Qhov tshwm sim ntawm Salicylic Acid
Salicylic acid yog ib qho tseem ceeb ua tshuaj kho pob txuv, dandruff, pob txuv, thiab lwm yam kab mob ntawm daim tawv nqaij vim nws muaj peev xwm tshem tawm txheej txheej ntawm daim tawv nqaij. Yog li, salicylic acid yog cov khoom tseem ceeb hauv kev tsim cov khoom siv tawv nqaij; Piv txwv li, nws muaj txiaj ntsig zoo hauv qee cov tshuaj zawv plaub hau los kho dandruff. Nws yog ib qho tseem ceeb hauv kev tsim Pepto-Bismol, tshuaj siv los kho cov kab mob plab hnyuv. Tsis tas li ntawd, salicylic acid kuj tseem siv tau ua zaub mov noj.
YHyaluronic Acid yog dab tsi?
Hyaluronic acid yog ib qho polymeric organic molecule uas muaj cov tshuaj formula (C14H21NO11)n. Peb tuaj yeem categorize no compound nyob rau hauv qeb ntawm glycosaminoglycan compounds. Txawm li cas los xij, hyaluronic acid yog qhov tshwj xeeb vim nws tsuas yog tsis muaj sulfated glycosaminoglycan. Cov tshuaj no ib txwm tshwm sim hauv tib neeg lub cev. Nws tuaj yeem raug xa mus thoob plaws hauv cov khoom sib txuas, epithelial, thiab cov ntaub so ntswg neural.
Daim duab 02: Chemical Structural Unit of Hyaluronic Acid
Tsis tas li ntawd, tsis zoo li lwm cov glycosaminoglycan tebchaw, cov tshuaj no yog tsim nyob rau hauv plasma membrane (lwm cov glycosaminoglycan compounds hauv Golgi apparatus). Muaj ntau qhov tseeb tseem ceeb ntawm qhov sib xyaw no. Xav txog nws daim ntawv thov hauv kev lag luam tshuaj pleev ib ce, nws yog ib qho khoom siv hauv cov khoom siv tawv nqaij. Ntxiv mus, nws yog ib qho tseem ceeb raws li ib tug dermal muab tub lim nyob rau hauv cosmetic phais. Cov neeg tsim khoom tsim hyaluronic acid feem ntau ntawm cov txheej txheem microbial fermentation. Qhov no yog vim tus nqi qis dua thiab tsawg dua ib puag ncig muaj kuab lom. Cov kab mob loj uas lawv siv rau qhov no yog Streptococcus sp. Txawm li cas los xij, muaj kev txhawj xeeb heev txog cov txheej txheem no vim tias cov kab mob microbial no yog cov kab mob.
Qhov txawv ntawm Salicylic Acid thiab Hyaluronic Acid yog dab tsi?
Peb tuaj yeem pom salicylic acid ua ib qho molecule, tab sis hyaluronic acid muaj ntau dua ib chav tsev sib txuas los ntawm kev sib txuas. Yog li ntawd, peb tuaj yeem muab nws lub npe hu ua polymeric. Yog li, qhov sib txawv tseem ceeb ntawm salicylic acid thiab hyaluronic acid yog salicylic acid yog cov khoom siv monomeric, hos hyaluronic acid yog cov khoom siv polymeric. Salicylic acid zoo nkaus li tsis muaj xim rau dawb crystalline khoom uas tsis muaj ntxhiab thaum hyaluronic acid tshwm sim hauv tib neeg lub cev. Tsis tas li ntawd, salicylic acid yog siv los ua cov tshuaj kho pob txuv, dandruff, pob txuv thiab lwm yam kab mob ntawm daim tawv nqaij vim nws muaj peev xwm tshem tawm cov txheej txheem ntawm daim tawv nqaij thaum hyaluronic acid yog siv nyob rau hauv kev lag luam tshuaj pleev ib ce thiab yog ib yam khoom muaj nyob rau hauv cov khoom tu tawv nqaij. Yog li, qhov no yog qhov sib txawv ntawm salicylic acid thiab hyaluronic acid raws li kev siv.
Cov hauv qab no qhia txog qhov sib txawv ntawm salicylic acid thiab hyaluronic acid hauv daim ntawv tabular.
Summary – Salicylic Acid vs Hyaluronic Acid
Qhov sib txawv tseem ceeb ntawm salicylic acid thiab hyaluronic acid yog salicylic acid yog ib yam khoom monomeric, whereas hyaluronic acid yog ib yam khoom polymeric.
