Differences Between Synthetic Lactic Acid and Fermented Lactic Acid

  Synthetic lactic acid Fermented lactic acid
Production of raw materials ´╝«aphtha (a petroleum-derived raw material) is hydrolyzed to produce lactic acid. Lactic acid is produced by using microorganisms from plant-derived material.
Refining process Refined using chemical reactions Refined using chemical reactions
Optical activity DL-bodies with no optical activity In addition to material with optical activity, also produces material with no optical activity material with mainly L-bodies and material with mainly D-bodies, depending on type of microorganisms used during fermentation.
