Dimethyl Lauramine Oleate

What is Dimethyl Lauramine Oleate?

Dimethyl Lauramine Oleate is a synthetic cationic surfactant derived from lauryl dimethylamine and oleic acid, a fatty acid sourced from plant oils. Primarily featured in hair care products such as conditioners and shampoos, it also appears in select skin care items. This ingredient functions by forming a thin, positively charged layer on negatively charged hair or skin surfaces, which minimizes friction between strands or with skin. This action imparts smoothness, eases detangling, and combats static buildup for improved handling. Additionally, it influences formulation rheology by thickening or stabilizing emulsions, ensuring even application and product consistency. Its lipid-like structure mimics natural oils, delivering lightweight conditioning without heavy residue, making it suitable for frequent use in rinse-off applications.
