Trisodium Ethylenediamine Disuccinate

Description

Trisodium Ethylenediamine Disuccinate (TEDS) is a synthetic chelating agent widely used in skincare and cosmetic formulations. This water-soluble compound is derived from ethylenediamine and succinic acid, forming a biodegradable alternative to traditional chelators like EDTA. TEDS effectively binds metal ions, particularly iron, copper, and calcium, preventing their negative effects on product stability and performance.

In skincare, TEDS serves multiple functions. It acts as a preservative booster, enhancing the efficacy of antimicrobial agents and extending product shelf life. Its metal-binding properties help protect formulations from color changes and rancidity caused by metal-induced oxidation. TEDS also improves the feel and clarity of products by preventing the formation of precipitates or cloudiness.

Environmental considerations have increased the popularity of TEDS, as it readily biodegrades in wastewater treatment processes. It demonstrates low toxicity and minimal bioaccumulation potential, making it a more eco-friendly option compared to persistent chelators.

Typically used at concentrations between 0.1% and 1%, TEDS is compatible with a wide range of skincare ingredients and formulation types. Its stability across various pH levels and temperatures further contributes to its versatility in product development.
