Product Q&A

Q:What is the difference between sodium citrate anhydrous and dihydrate?

The only difference is that sodium citrate dihydrate contains 2 crystal water molecules. There is almost no difference in chemical features and applications.

Q:What are the main applications of Sodium Citrate Dihydrate?

It is used in the food industry as an acidity modifier and color fixative, in detergents as a water softener, in cosmetics, and in the chemical industry.

Q:How does it function as a water softener in detergents?

It replaces STPP by chelating Ca2+ and Mg2+ ions. Its chelated salts have higher solubility in cold water than hot water, offering better performance than zeolite.

Q:Is this product safe for food contact?

Yes, it has low toxicity and is widely used in food processing as a modifier, antioxidant, and flavor remover in various mass-produced foods.

Q:What is the shelf life of the product?

The standard shelf life listed in the COA is 2 years. However, if stored properly (sealed bags, away from sunlight and moisture), the actual shelf life can be slightly longer.
