Citric acid occurs as colourless crystals or as white, crystalline powder with a strongly acidic taste. It is very soluble in water, freely soluble in ethanol (96 %) and sparingly soluble in ether. Citric acid is non-toxic and has a low reactivity. It is chemically stable if stored at ambient temperatures. Citric acid is fully biodegradable and can be disposed of with regular waste or sewage.
