Citric acid monohydrate is used in the preparation of citrate buffer in platelets for intravital microscopy. It acts as a pH-control agent in foods, beverages and pharmaceuticals applications. It acts as an iron chelator. In animals, it improves the utilization of nutritional calcium. It is a useful buffer component for antigen and epitope unmasking. It is also used as an acidifier, a flavoring agent and a chelating agent.For cosmetics and personal care products.For pharmaceutical preparations, especially effervescent tablets.
Solubility : Citric Acid Monohydrate is very soluble in water, freely soluble in ethanol and sparingly soluble in ether.
Stability and storage : Citric Acid Monohydrate may be stored for 48 months from the date of manufacture in the unopened original container. A relative humidity of 50% and a temperature range of 10%u201330 °C are the most suitable conditions for storage. Temperatures above 40 °C and a relative humidity above 70% should be avoided in order to prevent caking, especially the Fine Granular form. The stacking of the Fine Granular form for long periods is not recommended. Stability tests have shown that Citric Acid Monohydrate is chemically stable for at least five years in tightly closed containers under proper storage conditions.
Hazard Statements : Causes skin irritation. Causes serious eye irritation. May cause respiratory irritation.
Precautionary Statements : Avoid breathing dust/fume/gas/mist/vapours/spray. Wear protective gloves and eye/face protection. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. IF INHALED: Remove to fresh air and keep at rest in a position comfortable for breathing. Store locked up.
