Overview

Isostearic acid is a highly branched, saturated fatty acid used for emulsifying and cleansing.

This clear liquid has minimal odors and can help produce oil-in-water emulsions, which tend to be lightweight lotions and refreshing creams.

The same features that make isostearic acid a great emulsifier also make it an effective cleansing agent, also known as a surfactant. This nonionic surfactant can surround dirt and oil particles on the skin and allow them to be easily washed away by water. This is thanks to the molecule having both an oil-loving side and a water-loving side, which is a trait of cleansing agents.
