TETRASODIUM IMINODISUCCINATE

Description

Tetrasodium Iminodisuccinate is a biodegradable chelating agent increasingly used in skincare and cosmetic formulations. This synthetic compound is derived from aspartic acid, a naturally occurring amino acid. Its primary function is to bind metal ions, particularly calcium and magnesium, which can interfere with product stability and efficacy.

In skincare, Tetrasodium Iminodisuccinate enhances the preservation of formulas by preventing metal-induced oxidation and degradation of active ingredients. It also improves the foaming and cleansing properties of products by softening hard water. This ingredient is particularly valuable in anti-aging formulations, as it helps protect antioxidants from metal-catalyzed breakdown.

Unlike EDTA, a common chelating agent, Tetrasodium Iminodisuccinate is readily biodegradable, making it an environmentally friendly alternative. It demonstrates high stability across a wide pH range and is compatible with most cosmetic ingredients. The compound is generally well-tolerated by skin and has a low potential for irritation or sensitization.

Regulatory bodies, including the EU and FDA, have approved Tetrasodium Iminodisuccinate for use in personal care products, recognizing its safety profile and functional benefits in cosmetic formulations.
