Formula IngredientChelating AgentINCI: 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.

Trisodium ethylenediamine disuccinate is well tolerated at typical cosmetic concentrations. It is a chelating agent used at low levels and is not expected to cause skin irritation. No EU CosIng Annex II or III restrictions apply.
EDDS does not increase photosensitivity. No sun protection precautions are required.
Trisodium ethylenediamine disuccinate is a biodegradable chelating salt used at very low concentrations in cosmetics. No reproductive or developmental toxicity concerns are noted in available safety databases. Considered safe during pregnancy.
