Quaternium-75

What is Quaternium-75?

Quaternium-75 is a quaternary ammonium compound, a class of synthetic cationic surfactants derived from fatty acids and amines. It appears in hair care items like conditioners and detanglers. In formulations, it works by depositing a positively charged layer onto negatively charged hair shafts, neutralizing static electricity buildup. This action minimizes friction between strands, promoting detangling, softness, and a smoother texture. Its surface-modifying properties also aid in even distribution of other product components, enhancing overall performance in rinse-off and leave-on hair treatments without residue concerns in typical use levels.
