Conditions to avoid Avoid temperatures above >392°F(200°C), Materials to avoid Strong oxidizing agents. Hazardous decomposition Thermal decomposition can lead to release of irritating gases products and vapors, Acute toxicity LD50/oral/rat = 3730 mg /kg (Lactic Acid). Local effects Irritating to eyes. Specific effects Based on tests with L(+)-Lactic acid and its salts, there is no evidence to suggest carcinogenic nor mutagenic properties from lactic acid itself nor from the lactate portion of its metal salts. -Further information... .. - -As-an-important.metabolite-in man,-animals and plants, it Js. naturally formed and metabolized.
