Ukusetyenziswa
I-DL - Tartaric Acid sisixa esisetyenziswa ngeendlela ezahlukeneyo. Sisetyenziswa kakhulu kwishishini lokutya nelesiselo njenge-acidulant, i-flavour enhancer, kunye ne-pH regulator. Ingabonelela ngencasa emuncu kwaye iphucule incasa yeemveliso ezifana neziselo ezibandayo, iijusi zeziqhamo, kunye neelekese. Kwishishini lezemithi, isetyenziswa ekwenzeni amayeza nanjenge-chiral resolving agent. Ukongeza, i-DL - Tartaric Acid isetyenziswa kwishishini leekhemikhali ekwenzeni ii-esters kunye nezinye ii-organic compounds. Ikwasetyenziswa kwezinye iimveliso ze-cosmetic kunye nezokhathalelo lomntu ukulungisa i-pH kunye nokuphucula uzinzo lweefomyula.
