Description - Disodium EDTA is a high-purity, synthetic chelating agent that plays a crucial role in modern cosmetic formulation. Derived from ethylenediaminetetraacetic acid, this off-white, odorless powder is a staple in premium skin, hair, and body care products. Its main function is to bind and neutralize metal ions that are often present in water or raw materials, preventing them from destabilizing formulations. EDTA is widely used to preserve product clarity, enhance foam quality, prevent discoloration, and improve the overall effectiveness of preservatives. Especially suited for neutral to mildly acidic systems, this ingredient is essential for formulating stable, high-performance handmade cosmetics.
Benefits:
Chelates metal ions to prevent oxidative damage and spoilage
Boosts preservative efficacy as a synergistic co-preservative
Prevents fragrance and vitamin degradation (e.g., Vitamin C & E)
Reduces discoloration and haze formation in water-based formulas
Improves foam performance and rinseability in cleansers and shampoos
Stabilizes emulsions and surfactants for long-lasting, smooth textures
Helps maintain pH balance and formula clarity
