OLETH-3

Safety grade: A

Oleth-3 is a synthetic ingredient created by chemically modifying oleic acid (a natural oil component) combined with ethylene oxide. It acts like a bridge that helps oil and water mix together smoothly in cosmetic products.

This ingredient works as an emulsifier to blend oil and water-based components together, preventing them from separating and creating a smooth, stable texture in creams, lotions, and other cosmetic formulations.
