PRODUCT DATA
CITRIC ACID (Anhydrous)
DESCRIPTION
Anhydrous citric acid (C6H807) is a multi-purpose weak organic acid. It is widely used in the
food, beverage and detergent industry, and also finds some oilfield applications. Citric acid is
relatively non-toxic, non-corrosive and is biodegradable.

APPLICATION
Anhydrous citric acid is widely used in oilfield completion and stimulation operations as an
iron sequestrant. It can also aid in reducing water requirements and in retarding of oil well
cements. Because of its ease and relative safety of handling, citric acid can be used in the pH
adjustment of drilling fluids, completion fluids and industrial/oil-well waste fluids.
MIXING AND HANDLING
Although citric acid is of low hazard and toxicity, excess exposure to dust should be avoided to
prevent irritation to the eyes, skin and respiratory tract. Use good industrial hygiene practices,
wear goggles and a dust mask when handling the material. Ensure that the work area is
sufficiently ventilated to avoid dust build-up and wear protective clothing to prevent excess
skin contact. Citric acid is non-flammable. As with all organic material, caution is advised
when storing or handling near strong oxidizing agents, alkali metals or strong bases.
