In the world of chemical ingredients, surfactants play a pivotal role, enabling everything from effective cleaning to luxurious lather. For manufacturers of personal care products and household cleaners, selecting the right surfactant is crucial for product performance and consumer satisfaction. Two commonly used anionic surfactants are Sodium Lauryl Ether Sulfate (SLES) and Sodium Lauryl Sulfate (SLS). While both offer excellent detergency and foaming capabilities, SLES 70% often emerges as the preferred choice due to its improved properties.

Understanding the Difference: SLES vs. SLS

Sodium Lauryl Sulfate (SLS) is a potent surfactant that effectively removes dirt and oils. However, its harshness can lead to skin and eye irritation for some individuals, especially those with sensitive skin. This is often due to its smaller molecular structure, which allows it to penetrate the skin more readily.

Sodium Lauryl Ether Sulfate (SLES) 70% is an ethoxylated derivative of SLS. The addition of ethoxy groups (typically an average of 2 EO units, hence the common designation as SLES 2EO) results in a larger molecule. This structural difference makes SLES significantly milder on the skin and eyes compared to SLS. This enhanced mildness, coupled with excellent cleansing, emulsifying, and foaming properties, makes SLES 70% a workhorse ingredient for many applications.

Why SLES 70% is the Manufacturer's Choice

For product formulators, the benefits of SLES 70% are clear:

  • Milder Formulation: SLES 70% is less likely to cause irritation, making it ideal for shampoos, body washes, facial cleansers, and baby products. This reduces the risk of adverse reactions and enhances consumer comfort.
  • Excellent Foaming and Cleansing: Despite its mildness, SLES 70% produces a rich, stable lather and effectively removes grease and grime, comparable to SLS.
  • Compatibility and Stability: It is compatible with a wide range of other surfactants (except cationics) and performs well in various water hardness conditions, including hard water.
  • Biodegradability: SLES 70% offers good biodegradability, aligning with growing consumer demand for environmentally friendly products.
