LAURETH-4 CARBOXYLIC ACID

Safety grade: A

This is a gentle cleaning ingredient made from coconut oil that helps remove dirt, oil, and makeup from skin and hair. It's milder than many other cleansers and works well in products designed for sensitive skin.

As a surfactant, it reduces the surface tension of water to help lift away oils and impurities, making it an effective yet gentle cleanser in facial cleansers, shampoos, and body washes.
