Disodium EDTA
INCI · Disodium EDTA · also EDTA, Disodium Ethylenediaminetetraacetate
Overview
A chelator rather than a preservative in its own right: it binds trace metal ions left over from water and raw materials, which would otherwise speed up rancidity and blunt the preservative system. It also helps cleansers foam in hard water.
Who it's for
A background formulation aid found in almost every water-based product.
Cautions
Used at very low levels and not a skin-treatment ingredient; environmental persistence is the more discussed concern rather than skin tolerance.
