SLES vs. SLS: Why Sodium Lauryl Ether Sulfate is the Preferred Choice
At NINGBO INNO PHARMCHEM CO.,LTD, we often field questions about the differences between Sodium Lauryl Sulfate (SLS) and its derivative, Sodium Lauryl Ether Sulfate (SLES). While both are anionic surfactants and share some common applications, SLES 70% has emerged as the preferred choice for many product formulations, primarily due to its enhanced properties, particularly concerning skin compatibility.
The key distinction lies in their chemical structure and manufacturing process. SLS is produced by sulfating lauryl alcohol. SLES, on the other hand, is created by ethoxylating lauryl alcohol before sulfation. This additional ethoxylation step introduces polyethylene oxide chains, which significantly alters the molecule's behavior. The result is a surfactant that is less irritating to the skin and eyes than SLS. This lower irritation potential is a critical factor in the widespread use of SLES 70% in personal care products where prolonged skin contact is common, such as shampoos, body washes, and facial cleansers.
While SLS is known for its powerful lathering and cleaning capabilities, it can also strip the skin of its natural oils, leading to dryness and irritation for some individuals. SLES maintains excellent detergency and foaming properties but does so with a gentler touch. This makes it an ideal candidate for brands focusing on sensitive skin formulations or those aiming to provide a luxurious, less harsh cleansing experience. The ability to purchase SLES 70% with consistent quality and at a competitive price point makes it an attractive option for manufacturers looking to balance performance with consumer comfort.
Furthermore, SLES often exhibits better solubility and compatibility with other formulation ingredients compared to SLS, simplifying the product development process. For businesses seeking a reliable supplier of SLES 70%, NINGBO INNO PHARMCHEM CO.,LTD ensures high standards and availability. Choosing SLES 70% means opting for a proven, effective, and gentler surfactant that meets the evolving demands of consumers and formulators alike.
