Product Characteristics

1. Phosphorus-free, chlorine-free, safe and environmentally friendly, easily degradable, reducing the risk of adverse skin reactions;

2. Good stability, resistant to high temperatures and strong alkalis;

3. Selectively chelates iron (even in the presence of calcium and magnesium); its chelating ability for heavy metals such as copper, iron, manganese, and nickel is comparable to EDTA, and its chelating power for calcium, magnesium, zinc, and other transition metal ions is also very strong. It works even better when used in combination with other chelating dispersants and can be used as a cleaning agent for alkaline earth metals and heavy metals.

Applications:

1. Personal care products such as shower gels, shampoos, facial cleansers, and hair dyes, as well as various detergents and cleaning agents.

2. Cosmetics

3. Electronic chemicals

4. Hydrogen peroxide bleaching

5. When used in combination with sodium silicate, it can reduce the formation of silica scale.
