Sodium lauryl sulfoacetate(SLSA) is an anionic surfactant with good detergency, foaming, solubilizing and emulsifying properties; it has good calcium soap dispersion and hard water resistance.
It is milder compared to fatty alcohol polyoxyethylene ether sulfate. It can be used as a substitute for sodium stearate, and can also be used in baby washing products.
It is used as a surfactant and foaming agent in cosmetics, referred to as SLSA. Although it is very similar to SLS, SLSA is safer, gentler, and has good hydrophilicity, making it easier for oil to be rinsed out by water, and is suitable for various skin and hair types.
