Lactic Acid Regulators

Lactic acid feem ntau yog siv rau hauv cov zaub mov ua acidulant, preservative thiab tsw enhancer. Raws li ib tug acidulant, nws muab ib tug maj thiab ntev -siv qaub saj thiab yog dav siv nyob rau hauv dej haus, jams, candies thiab brewing; raws li ib tug natural preservative, nws inhibits kev loj hlob ntawm teeb meem kab mob los ntawm txo tus nqi pH, ncua lub txee lub neej ntawm cov khoom xws li pickles, nqaij cov khoom thiab zaub xam lav hnav khaub ncaws; Nyob rau tib lub sijhawm, nws tuaj yeem txhim kho kev ntxhib los mos thiab tsw ntawm cov khoom siv mis nyuj (yogurt, cheese) thiab ua kom zoo dua qhov ua tau zoo ntawm cov khob noom cookie hauv ci.

Lactic acid, raws li alpha-hydroxy acid (AHA), feem ntau ua haujlwm hauv cov tshuaj pleev ib ce los ntawm kev muab moisturization, exfoliation, thiab pH tswj. Nws yog ntxiv rau lub ntsej muag cleansers, toners, cream, thiab lub cev pleev xim, maj mam tshem tawm cov laus ntawm daim tawv nqaij ntawm qhov chaw, txhawb kev rov ua dua tshiab ntawm tes, thiab txhim kho roughness, nplua kab, thiab cov tawv nqaij tsis sib xws.

Qhov tseem ceeb tshaj plaws kev lag luam daim ntawv thov ntawm lactic acid yog raws li ib tug monomer rau synthesizing polylactic acid (PLA) - ib tug biodegradable thiab ib puag ncig tus phooj ywg yas, uas yog dav siv nyob rau hauv zus tau tej cov tableware pov tseg, ntim zaj duab xis, 3D luam ntawv filaments, thiab ua liaj ua teb mulch films, hloov cov tsoos petroleum{2} Tsis tas li ntawd, cov derivatives xws li ethyl lactate tuaj yeem siv tau raws li qis- lom thiab biodegradable ntsuab kuab tshuaj ntxuav cov xim thiab ntxuav hauv kev lag luam hluav taws xob; calcium lactate thiab sodium lactate, thiab lwm yam, yog siv los ua buffers, moisturizers lossis coagulants.
