Qhov sib txawv tseem ceeb ntawm zinc PCA thiab zinc pyrithione yog zinc PCA yog carboxylic acid compound, whereas zinc pyrithione yog kev sib koom ua ke.
Zinc PCA thiab zinc pyrithione yog cov khoom xyaw tseem ceeb uas muaj ntau yam siv hauv cov khoom lag luam sib txawv, xws li cov khoom siv tawv nqaij.
Zinc PCA (Zinc Pyrrolidone Carboxylic Acid) yog dab tsi?
Zinc PCA lossis zinc pyrrolidone carboxylic acid yog cov kab sib txawv ntawm zinc thiab muaj txiaj ntsig zoo hauv kev kho pob txuv, tawg, thiab lwm yam. Nws tseem hu ua "zinc ntsev." Nws yog pom tau tias zoo heev tiv thaiv pob txuv thiab breakouts. Zinc PCA tuaj yeem txo qhov redness thiab sebum secretion thiab txhawb cov txheej txheem kho ntawm daim tawv nqaij.
Zinc PCA yog qhov sib txawv ntawm cov zinc, thiab nws muaj txiaj ntsig zoo hauv kev tu tawv nqaij hauv daim ntawv ntawm zinc ntsev. Cov tebchaw no muaj zinc hauv txoj kev yooj yim dua soluble. Qhov no txhais tau tias cov no tau tso tawm yooj yim thaum siv rau ntawm daim tawv nqaij.
Ntxiv mus, PCA yog ib qho amino acid derivative uas tuaj yeem tshwm sim hauv daim tawv nqaij thiab yog ib feem ntawm lub ntuj moisturizing. Qhov xwm txheej no paub txog cov khoom tshwj xeeb uas tuaj yeem khi dej. Ntawm no, cov ntsev ntawm PCA zoo li khi dej hauv daim tawv nqaij kom txo tau cov dej transepidermal. Qhov no yog vim li cas ua rau nws muaj txiaj ntsig zoo hauv moisturizing thiab hauv cov tshuaj pleev ib ce ua rau cov tawv nqaij qhuav. Cov khoom ntawm zinc PCA tuaj yeem piav qhia tias yog tshuaj tua kab mob antioxidant thiab tshuaj tiv thaiv kab mob.
Zinc Pyrithione yog dab tsi?
Zinc pyrithione lossis pyrithione zinc yog kev sib koom ua ke ntawm zinc. Cov tshuaj no muaj cov khoom siv fungistatic thiab bacteriostatic, ua rau nws muaj txiaj ntsig zoo hauv kev kho seborrheic dermatitis thiab dandruff. Hauv lwm lo lus, nws tuaj yeem cuam tshuam kev faib cov kab mob fungal thiab kab mob.
Daim duab 01: Cov Qauv Tshuaj ntawm Zinc Pyrithione
Cov tshuaj formula ntawm zinc PCA yog C10H8N2O 2S2Zn. Cov molar mass ntawm no compound yog 317.70 g / mol. Nws zoo nkaus li cov khoom tsis muaj xim, thiab nws cov ntsiab lus melting ntawm cov khoom no yog 240 degrees Celsius thaum nws decomposes ntawm qhov kub siab dua. Solubility ntawm zinc pyrithione hauv dej yog 8 ppm ntawm pH=7.
Cov ligand uas tsim los ntawm pyrithione feem ntau tshwm sim ua monoanion. Cov ligands no yog chelated rau Zn2+ ntawm cov pa oxygen thiab sulfur chaw. Ntxiv mus, nyob rau hauv nws lub xeev crystalline, cov compound no tshwm sim raws li ib tug centrosymmetric dimer. Nyob rau hauv lub dimer no, cov zinc yog khi rau ob tug sulfur thiab peb oxygen chaw. Txawm li cas los xij, thaum nws tshwm sim hauv kev daws teeb meem, cov dimers no nyiam sib cais los ntawm kev sib tsoo ntawm ib daim ntawv cog lus Zn-O. Tsis tas li ntawd, pyrithione tuaj yeem piav qhia raws li lub hauv paus conjugated uas tau muab los ntawm 2-mercaptopyridine-N-oxide, uas yog ib qho derivative ntawm Pyridine-N-oxide.
Daim duab 02: Dimer of Zinc Pyrithione
Zinc pyrithione yog siv rau hauv cov tshuaj, kev tsim cov tshuaj pleev ib ce, daim txhuam cev, khaub ncaws, thiab lwm yam. Nyob rau hauv cov tshuaj, zinc pyrithione muaj txiaj ntsig zoo hauv kev kho dandruff thiab seborrheic dermatitis. Cov tshuaj no qhia txog cov tshuaj tua kab mob thiab muaj txiaj ntsig zoo tiv thaiv ntau yam kab mob uas tau los ntawm Streptococcus thiab Staphylococcus genera. Muaj qee qhov kev siv kho mob, suav nrog kev kho mob psoriasis, eczema, ringworm fungus, kis las ko taw, tawv nqaij qhuav, atopic dermatitis, thiab lwm yam. Tsis tas li ntawd, muaj kev siv zinc pyrithione hauv kev tsim cov xim, qhov twg nws tuaj yeem tiv thaiv qhov chaw ntawm mildew thiab algae. Qee cov sponges hauv tsev kuj tau tsim siv zinc pyrithione vim nws cov kab mob tua kab mob. Ib yam li ntawd, zinc pyrithione yog siv hauv kev lag luam textile hauv kev tsim khaub ncaws vim nws cov khoom siv tshuaj tua kab mob.
Qhov txawv ntawm Zinc PCA thiab Zinc Pyrithione yog dab tsi?
Zinc PCA thiab zinc pyrithione yog cov organic tebchaw uas muaj ntau pawg. Qhov sib txawv tseem ceeb ntawm zinc PCA thiab zinc pyrithione yog zinc PCA yog carboxylic acid compound, whereas zinc pyrithione yog kev sib koom ua ke.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm zinc PCA thiab zinc pyrithione hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Zinc PCA vs Zinc Pyrithione
Zinc PCA lossis zinc pyrrolidone carboxylic acid yog cov kab sib txawv ntawm zinc thiab muaj txiaj ntsig zoo hauv kev kho pob txuv, tawg, thiab lwm yam. Zinc pyrithione lossis pyrithione zinc yog kev sib koom ua ke ntawm zinc. Qhov sib txawv tseem ceeb ntawm zinc PCA thiab zinc pyrithione yog zinc PCA yog carboxylic acid compound, whereas zinc pyrithione yog kev sib koom ua ke.
