Oleth-110 is a synthetic ingredient created by combining oleic acid (a natural oil component) with ethylene oxide. It's a waxy, emulsifying substance that helps blend oil and water-based ingredients together.

This ingredient acts as an emulsifier and surfactant in cosmetic formulations, helping to combine and stabilize ingredients that normally don't mix well together, creating smooth and uniform products.
