Product Description

Physical and Chemical Properties

1. Appearance: White powder or fine granular crystals.

2. Solubility: Easily soluble in water, and the aqueous solution is weakly alkaline.

3. Core Function: It can undergo strong chelation with metal ions such as calcium and magnesium, softening hard water.

Safety and Precautions

1. Compliance Use: As a food additive, there are strict standards and regulations for its maximum usage amount in food by various countries.

2. Environmental Impact: Excessive phosphorus-containing detergent wastewater discharged into natural water bodies may cause water body eutrophication problems, so environmentally friendly detergents are gradually restricting or reducing the use of phosphates.
