Dibasic sodium phosphate or Sodium dibasic phosphate is a chemical compound, one of the hydrated salts of sodium acid generated from phosphoric acid.
It appears as a white powder, soluble in water and the aqueous solution is weakly alkaline.
What it is used for and where
Medical
Together with Monobasic Sodium Phosphate, it is used in both adults and children in evacuative solutions such as disposable enemas for the treatment of constipation, as a pH regulator and saline laxative, for the treatment of acute and chronic constipation and also for colon cleansing as a preparation for surgical procedures (1). These chemical compounds increase water content and stool volume, creating a rectal distension effect. The required effect is usually produced within about 5 minutes.
Dibasic sodium phosphate is also used as therapy in lead poisoning.
Dentistry
The incorporation of dibasic sodium phosphate as a buffering agent in the composition of the mineral trioxide aggregate is recognised as one of the solutions to improve its properties, reduce time and achieve a diametral tensile strength of 4.9 MPa at the initial 6-hour period.(2). Nucleating agent.
Human nutrition
The addition of dibasic sodium phosphate to meat increases the pH value and ionic strength of the meat, improving water retention and the overall yield of the final product.
Baking agent to prevent oxidation, emulsifier
Animal feed
Dibasic sodium phosphate is used for oral phosphorus supplementation in animal feed. In Qianbei-Pockmarked goats suffering from a disorder referred to as 'Ruanguzheng's disorder', disodium hydrogen phosphate supplementation prevented and cured the disorder (3).
