Sodium Lauryl Ether Sulfate (SLES) 70% is a widely used anionic surfactant recognized for its excellent foaming, cleansing, and emulsifying properties. As a primary raw material in numerous formulations, SLES 70% is essential for manufacturing a diverse range of consumer and industrial products.

Chemically identified by CAS Numbers 9004-82-4, 68585-34-2, and 68891-38-3, SLES 70% typically presents as a pale yellow to colorless viscous liquid or paste. It possesses a characteristic mild odor and is highly soluble in water, forming clear or slightly opalescent solutions. Its high viscosity can be adjusted by adding salt or water, making it versatile for different product formulations. The density of SLES 70% usually ranges from 1.05 to 1.10 g/cm³.

The primary applications of SLES 70% span several industries. In Personal Care and Cosmetics, it is a foundational ingredient in shampoos, body washes, shower gels, facial cleansers, hand soaps, and bubble baths, providing robust lather and effective cleansing. It is generally considered less irritating than Sodium Lauryl Sulfate (SLS), although soothing additives are sometimes included for sensitive skin applications.

Within the Household and Industrial Cleaning sector, SLES 70% serves as a key component in liquid laundry detergents, dishwashing liquids, and all-purpose cleaners due to its potent degreasing and dirt suspension capabilities. It is also used in car wash solutions and various industrial cleaning formulations, often combined with co-surfactants like cocamidopropyl betaine to enhance mildness and performance.

Beyond these major uses, SLES 70% finds application in Industrial and Specialty fields. This includes its role as an emulsifier in textile processing, a degreasing agent in leather treatment, a dispersant in paper manufacturing, a foam control agent in oilfield chemicals, and a stabilizer in emulsion polymerization processes.

Key benefits associated with SLES 70% include its high foaming capacity, even in hard water environments, its excellent solubility and compatibility with most water-based systems, and its ability to contribute to the desired viscosity of finished products. It is also considered a cost-effective surfactant, widely available for large-scale production.

While SLES 70% offers numerous advantages, it is important to note its potential for moderate irritation, especially with prolonged contact on sensitive or dry skin. Environmental considerations necessitate biodegradability testing; however, it is generally considered readily biodegradable under OECD standards.

Looking ahead, trends in the industry include the development of biobased SLES from renewable feedstocks and the formulation of low-irritant blends by combining SLES with amphoteric or non-ionic surfactants.
