EDTA 4NA Applications
Industrial cleaning, papermaking, textile, water treatment agent
High-efficiency water softener and chelating agent: An extremely important water softener and a powerful chelating agent for polyvalent metal ions. It effectively prevents calcium and magnesium ions in water from forming scale or from catalytic oxidation by metal ions.
Detergents and daily chemical additives: Widely used in liquid detergents, soaps, shampoos, and cosmetics as an anti-hard water agent and clarifying agent, significantly improving the detergency and formulation stability of detergents, and preventing product discoloration and rancidity.
Textiles, printing and dyeing, and papermaking: Used in textile printing and dyeing to remove trace metal impurities from fabrics and improve the brightness and uniformity of dyes; used as a bleaching stabilizer in papermaking.
Chemical analysis and industrial cleaning: Used for chemical cleaning of boilers and heat exchangers, metal surface treatment, as an additive in electroplating solutions, and as a complexing titrant in analytical chemistry.
EDTA 4NA Storage
Stored in the dry and ventilated inside storeroom, prevent direct sunlight, slightly pile and put down.
