Description

Sodium Laureth Sulfate (SLES) is a high-performance anionic surfactant derived from renewable resources. It is a key ingredient valued for its excellent foaming, cleansing, and emulsifying properties, even in hard water and at low concentrations. This versatile chemical is essential for manufacturers in the personal care, home care, and industrial cleaning sectors seeking effective and cost-efficient formulation components.

Application

• Personal Care & Cosmetics: Primary surfactant in shampoos, body washes, facial cleansers, and bubble baths for rich, stable lather.
• Household & Institutional Cleaning: Core component in liquid dish soaps, laundry detergents, all-purpose cleaners, and car wash formulations.
• Industrial Cleaners: Used in formulations for hard surface cleaners, degreasers, and textile processing aids.
• Emulsion Polymerization: Acts as an emulsifier and stabilizer in the production of synthetic latexes, such as acrylics and styrene-butadiene rubber (SBR).
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to enhance wetting, spreading, and penetration.
