Usage
Personal Care: Chelates hard water and metal ions in raw materials, improving product cleaning power, foaming ability, and stability, extending shelf life, and ensuring even color in hair dyes.
Food Industry: Used as a food-grade chelating agent, antioxidant synergist, and stabilizer, preventing rancidity, browning, and precipitation caused by metal ion catalysis in food, extending shelf life.
Water Treatment: Used for industrial circulating water, boiler water softening and scale prevention, and removal of trace metal ions in pure/ultrapure water preparation.
Textile Printing and Dyeing: Protects bleaching agents during pretreatment, ensures even dyeing and color fixation during the dyeing process, and stabilizes finishing effects during post-treatment, solving printing and dyeing defects caused by metal ions.
Detergents and Cleaning Agents: Chelates hard water ions, improving the cleaning power of laundry detergents, dishwashing liquids, and industrial cleaning agents, and preventing limescale residue.
