Lactate yog siv los khaws zaub mov, moisturizing thiab tsw li
Kev piav qhia
Sodium L-lactate yog siv rau kev khaws cia zaub mov, moisturizing thiab tsw li, nrog rau casein toughening tus neeg saib xyuas thiab dej absorbing tus neeg sawv cev. Hais txog cov zaub mov bacteriostasis, L-sodium lactate tuaj yeem tsis tsuas yog inhibit qhov kev loj hlob ntawm cov kab mob lwj feem ntau, tab sis kuj muaj ntau yam kev txwv tsis pub muaj ntau yam kab mob, xws li Listeria monocytogenes, Salmonella, thiab lwm yam. Sodium L-lactate tau ua tiav hauv cov khoom siv nqaij tag nrho xws li nqaij npuas kib, nqaij nyug ci, nqaij qaib, thiab cov nqaij minced xws li cov hnyuv ntxwm kub, hnyuv ntxwm tshiab, hnyuv ntxwm thiab salami.

Daim ntawv thov
Nws yog tsuas yog siv nyob rau hauv kev ua thiab siv ntawm polylactic acid cov ntaub ntawv thiab cov synthesis ntawm chiral tshuaj thiab tshuaj tua kab intermediates.
Chiral compounds
Lactic acid esters siv D-lactic acid raws li raw cov ntaub ntawv yog dav siv nyob rau hauv zus tau tej cov naj hoom, hluavtaws resin coatings, nplaum thiab luam ntawv inks, thiab kuj nyob rau hauv kev tu cov roj av pipelines thiab hluav taws xob industries. Ntawm lawv, D-methyl lactate tuaj yeem sib tov sib xyaw nrog dej thiab ntau yam polar solvents, cellulose acetate, cellulose acetobutyrate, thiab lwm yam thiab ntau yam polar synthetic polymers, thiab muaj cov ntsiab lus melting. Nws yog ib qho hnyav heev nrog kub kub taw tes vim nws qhov zoo ntawm qhov kub thiab txias thiab qeeb evaporation tus nqi. Nws tuaj yeem siv los ua ib feem ntawm cov kuab tshuaj sib xyaw los txhim kho kev ua haujlwm thiab solubilization. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov khoom siv raw rau cov tshuaj, tshuaj tua kab thiab cov khoom ua ntej rau kev sib txuas ntawm lwm cov chiral compounds. , Nruab nrab.
Cov khoom degradable
Lactic acid yog raw khoom rau bioplastic polylactic acid (PLA). Lub cev lub cev ntawm cov ntaub ntawv PLA nyob ntawm seb muaj pes tsawg leeg thiab cov ntsiab lus ntawm D thiab L isomers. Cov racemate D, L-polylactic acid (PDLLA) synthesized los ntawm racemic D, L-lactic acid muaj cov qauv amorphous, thiab nws cov khoom siv tsis zoo, lub sij hawm degradation yog luv, thiab shrinkage tshwm sim hauv lub cev, nrog tus nqi shrinkage ntawm 50%. % lossis ntau dua, daim ntawv thov raug txwv. Cov saw ntu ntawm L-polylactic acid (PLLA) thiab D-polylactic acid (PDLA) tau teem caij tsis tu ncua, thiab lawv cov crystallinity, mechanical zog thiab melting point yog siab dua cov PDLLA.
