Navigating the world of surfactants can be complex, especially when considering ingredients for sensitive applications like personal care or consumer detergents. Two commonly encountered anionic surfactants are Sodium Lauryl Sulfate (SLS) and Sodium Lauryl Ether Sulfate (SLES). While they share similarities, understanding their distinct properties is crucial for product developers and procurement specialists. As a leading SLES supplier in China, we want to guide you on why SLES 70% is often the preferred choice.

Understanding the Core Differences: SLES 70% vs. SLS

Both SLS and SLES are effective cleaning agents known for their foaming and detergency properties. However, the subtle yet significant difference in their chemical structure leads to notable distinctions in their performance and safety profiles:

  • Chemical Structure: SLES is produced by ethoxylating lauryl alcohol before sulfation. This addition of ethoxy groups (the 'ether' part) makes SLES generally milder and less irritating to the skin and eyes compared to SLS, which is derived directly from lauryl alcohol. This makes SLES 70% a more suitable ingredient for products that come into regular contact with human skin.
  • Mildness and Irritation: A primary advantage of SLES 70% is its significantly lower potential for skin and eye irritation. While SLS can be harsh, especially at higher concentrations, SLES provides a gentler cleansing experience. This is a critical factor for manufacturers of shampoos, body washes, and facial cleansers, where consumer comfort and product safety are paramount. When you buy SLES 70% surfactant, you are opting for a milder, more consumer-friendly ingredient.
  • Foaming and Solvency: Both surfactants produce good foam, but SLES often generates a richer, more stable lather. SLES also exhibits better solubility in water and greater resistance to hard water compared to SLS, ensuring consistent performance across various water conditions. For formulators, this means greater predictability and reliability.
  • Biodegradability: SLES is recognized for its good biodegradability, aligning with increasing environmental consciousness in product development. This makes it an attractive option for companies aiming for greener formulations.
