About Quaternium-91

Quaternium-91 is a quaternary ammonium salt.[1] Because Quaternium-91 has a structure with both water-attracting and oil-attracting portions, its cleansing power, foam, and sensory feel may vary depending on the use concentration and the surfactants used with it. In cosmetics, it is used to reduce tangling and rough feel in hair and leave it smooth.[2]
