In the world of surfactants, Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) are often discussed together, but understanding their distinctions is key for effective product formulation. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing high-quality SLES 70%, a derivative that offers significant advantages over its precursor, SLS.

The primary difference lies in their chemical structure and resulting properties. SLS is a more straightforward molecule, known for its potent cleansing and foaming capabilities. However, it can also be quite harsh, potentially causing skin and eye irritation for some individuals. This is why many consumers and formulators seek alternatives.

SLES, on the other hand, is produced by ethoxylating SLS. This ethoxylation process adds ethylene oxide chains, which significantly alters the molecule's characteristics. The result is a surfactant that retains excellent cleansing and foaming properties but is notably milder and less irritating to the skin and mucous membranes. This improved mildness makes SLES a preferred choice for a vast range of personal care products, including shampoos, body washes, and facial cleansers, where gentle efficacy is paramount.

Furthermore, SLES generally exhibits better solubility in water compared to SLS, which can simplify formulation processes. Both are anionic surfactants, effective at reducing surface tension and emulsifying oils and dirt, but SLES offers a more balanced profile for sensitive applications. Its biodegradability and resistance to hard water also contribute to its widespread adoption.

When sourcing surfactants, choosing SLES 70% from a reliable supplier like NINGBO INNO PHARMCHEM CO.,LTD. ensures you are getting a high-purity product that offers superior mildness and performance. Whether you are reformulating existing products or developing new ones, understanding the benefits of SLES over SLS can lead to better consumer satisfaction and product safety.
