Description

Disodium Laureth Sulfosuccinate is a high-performance, mild anionic surfactant derived from lauryl alcohol ethoxylate. This compound is valued for its excellent foaming, cleansing, and emulsifying properties, even in hard water and across a wide pH range. It is a critical ingredient for formulators seeking gentle yet effective surface-active agents in personal care and industrial cleaning applications. Its superior compatibility and skin mildness make it a preferred choice for sulfate-free and sensitive skin formulations.

Application

• Personal Care Cleansers: A primary surfactant in mild shampoos, body washes, facial cleansers, and baby care products, often marketed as "sulfate-free."
• Cosmetic Formulations: Used in creamy makeup removers, conditioning cleansers, and foaming bath products for its rich lather and low irritation potential.
• Household & Industrial Cleaners: An effective foaming and wetting agent in light-duty dish liquids, all-purpose cleaners, and car wash solutions.
• Industrial Emulsification: Serves as an emulsifier and dispersant in agricultural formulations, textile processing aids, and emulsion polymerization.
