L-pyrrolidone -5- carboxylate yog ib hom amino acid derboxylic acid thiab cov kua txiv carboxylation ntawm glutamic acid. Feem ntau ntawm lawv muaj cov nyhuv ya tau zoo. Nyob rau tib lub sijhawm, vim qhov sib txawv ntawm cov ntsev ion, muaj qee qhov sib txawv ntawm lawv. Cov khoom lag luam yog sodium pyrrolidone carboxylate (PCA-K), PCA-CA), Zinc Pyrrolidone Catcoylate (PCA-ZN), thiab lwm yam.
Sodium pyrrolidone carboxylate (PCA sodium) yog cov tshuaj pleev li ntawm daim tawv nqaij. Nws yog ib qho kev ua kom zoo ntawm cov amino acids. Nws yog soluble hauv dej thiab ethanol, tab sis tsis nyob hauv cov roj. Nws muaj kev hygroscopicity muaj zog thiab tuaj yeem nqus dej ntawm huab cua. Nws muaj peev xwm ua kom muaj zog dua glycerol, propylene glycol thiab sorbitol, uas yog cov moisturizers. Mas siv nyob rau hauv cov tshuaj pleev ib ce moisturizer, cov tshuaj ua haujlwm haus luam yeeb thiab lwm yam kev siv hauv qab no.
Poov tshuaj pyrrolidone carboxylate (PCA-k) tau siv dav hauv kev haus luam yeeb vim nws lub luag haujlwm hauv kev txo cov coke thiab ua rau muaj kev phom sij thaum lub sijhawm haus luam yeeb.
Calcium pyrrolidone carboxylate (PCA-CA) yog qhov yooj yim tiv thaiv tib neeg lub cev piv nrog sodium thiab potassium ions. Nyob rau tib lub sijhawm, kev tshawb fawb tau pom tias pyrrolidone carboxylate ua lub luag haujlwm ntawm kev txhim kho cov menyuam yaus kev txawj ntse thiab cov kab mob cerebrovases hauv cov neeg laus thiab cov laus. Yog li no, calcium pyrrolidone carboxylate (PCA-CA) tshwm feem ntau hauv Tebchaws Meskas. Cov khoom kho mob (tsis muaj cov khoom lag luam hauv Suav teb).
Tsis zoo li cov khoom saum toj no, zinc pyrrolidone carboxylate (PCA-ZN) yog cov ntaub thaiv dawb lossis tsis tiv thaiv pob txuv, tiv thaiv kab mob, fungi.
Hangzhou Lianzhoul Tshuaj Co., Ltd, tam sim no tuaj yeem muab cov PCA-NA thiab PCA-ZN.
