Disodium EDTA
What is Disodium EDTA?
Disodium EDTA, the disodium salt of ethylenediaminetetraacetic acid, is a synthetic chelating compound commonly incorporated into cosmetics like cleansers, moisturizers, shampoos, and lotions. It functions by forming tight bonds with metal ions such as iron, copper, calcium, and magnesium present in water or raw materials. This prevents these ions from triggering oxidative reactions that could degrade active ingredients, cause emulsion breakdown, or lead to discoloration and odor changes. Beyond chelation, it aids in adjusting product viscosity, ensuring smooth flow and even distribution during use. By enhancing overall formulation integrity, Disodium EDTA supports consistent performance across various product types, from thin serums to thick creams, while maintaining clarity and efficacy over time.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Benefits
Stabilizes formulations by neutralizing metal ions that promote degradation.
