Description

Potassium Trihydrogen Ethylenediaminetetraacetate is a water-soluble potassium salt of EDTA, functioning as a powerful chelating agent. This compound is critical for binding and sequestering di- and trivalent metal ions, thereby preventing unwanted precipitation and catalytic degradation in sensitive formulations. It is an essential raw material for manufacturers in the pharmaceutical, personal care, and industrial cleaning sectors who require precise metal ion control.

Application

• Pharmaceutical Manufacturing: Used as a stabilizing agent in injectable solutions, ophthalmics, and topical formulations to chelate trace metals that can catalyze oxidation.
• Cosmetics & Personal Care: Acts as a preservative booster and sequestrant in shampoos, creams, and lotions to enhance shelf-life and product clarity.
• Industrial Cleaning & Descaling: A key component in liquid cleaners and detergents for boilers and heat exchangers to remove limescale and rust deposits.
• Laboratory & Analytical Reagents: Serves as a buffer component and metal masking agent in complexometric titrations and biochemical assays.
• Agrochemical Formulations: Employed in micronutrient fertilizers and pesticide solutions to improve stability and bioavailability.
• Textile & Pulp Processing: Utilized in dyeing processes and pulp bleaching to control water hardness and improve process efficiency.
