Ingredient review
Dimethyl Lauramine Oleate
INCI: Dimethyl Lauramine Oleate
A synthetic emulsifier that helps mix oil and water, but may be slightly drying for sensitive skin.
In plain English
Dimethyl Lauramine Oleate is a man-made ingredient that helps oil and water stay blended in products like cleansers and lotions. It works as a surfactant, meaning it can also help lift dirt and oil from the skin or hair. While effective, it can be a bit drying or irritating for very sensitive skin, so it's best used in rinse-off products.
