OLETH-5

Safety grade: A

Oleth-5 is a gentle surfactant derived from oleic acid (a natural oil component) that helps oil and water mix together smoothly. It's commonly used to create stable, smooth-textured products like creams and lotions.

This ingredient works as an emulsifier to blend oil and water-based ingredients together, preventing them from separating and creating a uniform, stable texture in cosmetic formulations.
