At NINGBO INNO PHARMCHEM CO.,LTD., we believe in demystifying the chemical components that shape our daily lives. Today, we focus on the science behind Sodium Lauryl Ether Sulfate (SLES) 70%, a powerful anionic surfactant. Understanding its molecular behavior helps us appreciate its broad applicability.

SLES 70% belongs to the class of anionic surfactants. Its structure features a hydrophilic head (sulfate group) and a lipophilic tail (fatty alcohol chain), enabling it to reduce surface tension between water and oil. This amphiphilic nature is the core of its functionality::

  • Detergency: SLES molecules surround grease and dirt particles, lifting them from surfaces and allowing them to be washed away with water. This makes it a primary choice for shampoos and dish soaps.
  • Emulsification: It allows immiscible liquids, like oil and water, to mix, creating stable emulsions essential for lotions and creamy cleansers.
  • Foaming: SLES is a highly effective foaming agent, producing a rich, stable lather that enhances the user experience in products like bubble baths and facial cleansers.
  • Wetting: It improves the ability of liquids to spread over surfaces, which is beneficial in applications ranging from textile processing to herbicide formulations.

The ethoxylation process in SLES production, compared to its predecessor SLS, leads to a more water-soluble and less irritating compound. This improved profile is critical for its widespread use in personal care products. For manufacturers, leveraging these properties requires understanding the concentration levels and compatibility with other ingredients. The consistent performance of SLES 70% in hard water conditions further solidifies its position as a versatile raw material in detergent manufacturing.

By exploring the surfactant performance of SLES 70%, we gain a deeper appreciation for the chemistry that makes everyday products effective and reliable. The purchase of such essential chemicals hinges on understanding their performance characteristics.
