PRODUCT OVERVIEW

Product Description

SCD 99% Sodium Citrate Dihydrate is a white crystalline sodium citrate salt containing two molecules of crystallization water. It is readily soluble in water and is used in detergent formulations primarily as a water-softening, chelating, and pH-buffering auxiliary. Its ability to interact with calcium, magnesium, and other metal ions helps improve formulation performance in hard-water conditions. Sodium Citrate Dihydrate is also used in food, cosmetic, and general chemical applications where buffering, sequestration, and formulation stability are required.
