Dipotassium EDTA
What is Dipotassium EDTA?
Dipotassium EDTA is the dipotassium salt of ethylenediaminetetraacetic acid (EDTA), a synthetic polycarboxylic acid designed for strong metal-binding capabilities. In cosmetics, it serves as a chelating agent across categories like moisturizers, cleansers, and hair care products. It works by forming stable complexes with trace metal ions from water, ingredients, or packaging, such as calcium, magnesium, iron, or copper. This action inhibits metal-catalyzed reactions that promote oxidation, emulsion breakdown, or microbial growth support, thereby preserving the formula's integrity, color, texture, and performance. Its water-soluble, non-volatile properties suit diverse pH environments in rinse-off and leave-on items, ensuring consistent quality without altering sensory attributes.
