TRIDECETH-3

Safety grade: A

Trideceth-3 is a man-made cleaning agent created by combining a natural plant-based oil with other chemical ingredients. It helps mix oil and water together in cosmetic products so they blend smoothly instead of separating.

This ingredient works as an emulsifier and surfactant to help combine ingredients that don't naturally mix, while also gently cleansing the skin.
