Disodium 1-[1-methyl-2-[(1-oxooctadec-9-enyl)amino]ethyl] 2-sulphonatosuccinate is an anionic surfactant derived from oleic acid and sulfosuccinate chemistry. Known for its excellent foaming and mild cleansing properties, it is widely used in shampoos, shower gels, and facial cleansers. This ingredient provides good emulsification, dispersing, and wetting characteristics, making it valuable in both personal care and industrial applications. Its mildness makes it suitable for sensitive-skin formulations.
