| Safety |
Citric acid is found in the human body, mostly in the bones. Usually consumed as part of a normal diet. Citric acid can be absorbed orally and is non-toxic when used as excipients. However, excessive or frequent use of citric acid can cause tooth erosion. Citrate and citrate also enhance intestinal aluminum absorption in kidney patients, resulting in an increase in harmful serum aluminum concentrations. Therefore, citrate or citrate containing products are not recommended when aluminum compounds are used to control phosphate absorption in patients with renal insufficiency. LD50 (mouse, IP): 0.9g /kg; LD50 (mouse, IV): 0.04 g/kg; LD50 (mouse, oral): 5.04g /kg; LD50 (mouse, SC): 2.7g /kg; LD50 (Rabbit, IV): 0.33g /kg; LD50 (rat, IP): 0.88 g/kg; LD50 (rat, oral): 3.0g /kg; LD50 (rat, SC): 5.5 g/kg

| Incompatibilities |
Citric acid is incompatibilities with potassium tartrate, basic gold rot, alkaline earth metal carbonate, bicarbonate, acetate and sulfide, as well as with oxidants, chemicals, reductants and nitrates. It may explode upon exposure to metal salts of nitric acid. During storage, sucrose can be extracted from syrups containing citric acid.

| Source and Preparation |
Citric acid occurs naturally in large quantities in plants and is extracted from lemon juice, which contains 5 to 8% citric acid, or from pear residue. Citric acid can be purified by double junction and monohydrate can be prepared from cooled concentrated aqueous solution.
