Description

White solid; [Merck Index] White to yellow odorless solid; [ICSC] Powder; [Sigma-Aldrich MSDS]

Sources/Uses

An antioxidant essential in the human diet; Used as an antioxidant for foods and therapeutic vitamin; [Merck Index] Used as an antioxidant and pH adjustor in cosmetics (over 75% in hair dyes and colors), for abscission of citrus fruit in harvesting, as a reducing agent in analytical chemistry, skin protectant, and UV sunscreen; [HSDB] Used in chemical synthesis; [IUCLID] Used as flavoring agent, antimicrobial agent, antioxidant, dough strengthener, nutritional supplement, pH control agent, sequestrant, and stabilizer or thickener for foods; [FDA] Permitted for use as an inert ingredient in non-food pesticide products; [EPA]

Comments

A strong reducing agent; A skin, eye, and respiratory tract irritant; [ICSC] Excessive doses (chronic ingestion or intravenous) can cause acute renal failure or nephropathy secondary to a metabolite, oxalic acid. Increased oxalic acid can acidify the urine and promote the formation of calcium oxalate crystals, which can cause renal injury. [Olson, p. 397] No evidence of carcinogenicity in mice or rats; [NTP] May cause irritation; [Sigma-Aldrich MSDS]
