Sodium Lauryl Ether Sulfate (SLES)

Sodium Lauryl Ether Sulfate (SLES) Liquid Surfactant

Sodium Laureth Sulfate 26% to 29% Active solution

Popular Laureth (Lauryl Ether) Sulfate / Sodium Laureth Sulfate Liquid is an excellent all around surfactant that is used in a wide variety of ways to develop top performing cleaning and washing formulas. SLES also known as sodium laureth sulfate or sodium lauryl ether sulfate  provides improved mildness over sodium lauryl sulfate without the sacrifice  of critical performance attributes, such as cleaning, foaming and viscosity response.

The lower irritation, milder properties of SLES liquid allow it to be used for all kinds of cleansing products, as well as, baby products, or wherever you want good cleansing without the harshness level of SLS.

SLES  can easily be formulated into bath and body products like shampoos or hand soaps. 

Products based on SLES can be thickened with salts, betaines, or amides, with the latter two also serving to enhance foaming properties.

Common Uses

• Mild Shampoos
• Bubble baths
• Detergents
• General Cleaners
• Wool washes
• Hand Soaps

Characteristics

• Very effective, even in hard water.
• Used primarily for flash foaming ability in shampoos, detergents and applications.
• Excellent skin compatibility, along with good foam and viscosity characteristics, all important considerations in shampoo, hand soap, and bath product formulations.
• Can be thickened with salts, betaines, and amides, with the latter two also offering foam enrichment. Combine with alkanolamides like Cocamide DEA (high foam booster) and coco betaine for high viscosity products that work in a wide range of conditions.
