When formulating products requiring surfactants, understanding the nuances between Sodium Lauryl Ether Sulphate (SLES) and Sodium Lauryl Sulfate (SLS) is critical. NINGBO INNO PHARMCHEM CO.,LTD. provides insight into these differences, explaining why SLES 70% is often the preferred choice for many modern applications. While both are anionic surfactants, their chemical structures lead to distinct performance characteristics.

The primary distinction lies in the ethoxylation process applied to SLES. This addition of ethylene oxide groups makes SLES significantly milder and less irritating to the skin and eyes compared to SLS. For products like shampoos, body washes, and facial cleansers, this mildness is a key advantage, ensuring a more pleasant user experience, especially for those with sensitive skin. While SLS is known for producing a more voluminous foam, SLES generates a creamier, more stable lather that is equally effective in cleansing and emulsifying oils and dirt.

Furthermore, SLES exhibits better solubility in water and greater resistance to hard water conditions than SLS, which can be a significant factor in formulating products for a global market. Manufacturers looking to buy SLES 70% often do so because of these enhanced properties and its ability to offer comparable cleaning power to SLS with a gentler profile. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes that by understanding these differences, formulators can select the most appropriate surfactant to achieve desired product performance, safety, and consumer appeal, making SLES 70% a superior option for a wide range of applications.
