Formula IngredientChelating AgentEthylenediamine Disuccinate
INCI: Trisodium Ethylenediamine Disuccinate
PARSING ARTIFACT: This entry and the 'trisodium' entry are two halves of the same ingredient — trisodium ethylenediamine disuccinate (EDDS). EDDS is a biodegradable chelating agent derived from the amino acid L-aspartic acid. It neutralises metal ions (especially copper and iron) in cosmetic formulations, preventing formula degradation, discolouration, and rancidity. It is marketed as a greener, readily biodegradable alternative to EDTA.
