In the world of surfactants, the distinction between Sodium Lauryl Sulfate (SLS) and Sodium Lauryl Ether Sulfate (SLES) is crucial for formulators. While both are anionic surfactants and perform well as cleansing agents, SLES, particularly the 70% grade offered by NINGBO INNO PHARMCHEM CO.,LTD., presents significant advantages that make it the preferred choice for a wide range of applications.

The primary difference lies in the production process. SLES is derived from SLS through ethoxylation, a process that adds ethylene oxide units to the molecule. This chemical modification results in a molecule that is generally milder and less irritating to the skin and eyes compared to SLS. For consumers, this translates to a more comfortable experience, especially for those with sensitive skin or when formulating products for babies and children. The gentler nature of SLES makes it a superior option for shampoos, body washes, facial cleansers, and other rinse-off personal care products.

Solubility is another key area where SLES shines. Its ethoxylated structure enhances its solubility in water, which is beneficial for creating stable and aesthetically pleasing liquid formulations. This improved solubility also contributes to its excellent foaming capabilities, producing a rich, dense lather that is highly valued in consumer products. While SLS is also soluble, SLES generally offers better performance in this regard across various conditions.

When it comes to detergency and emulsification, both SLS and SLES are effective. However, SLES often provides a more consistent performance, particularly in formulations with varying pH levels or in the presence of hard water. This reliability makes it a more predictable ingredient for formulators aiming for consistent product quality. The ability to buy SLES in a concentrated 70% grade also offers efficiency in transportation and storage for manufacturers.

The perception of SLES as a safer and milder alternative has led to its widespread adoption in the personal care industry, often replacing SLS in many formulations. Brands are increasingly seeking ingredients that align with consumer demand for gentler, yet effective, products. NINGBO INNO PHARMCHEM CO.,LTD. ensures that our SLES 70% meets these evolving market needs, providing a high-quality, reliable anionic surfactant.

In summary, while SLS has been a foundational surfactant, SLES 70% offers a more refined and consumer-friendly option. Its improved mildness, enhanced solubility, consistent performance, and good biodegradability make it an indispensable ingredient for formulators looking to create superior personal care and cleaning products. Choosing SLES 70% from a trusted supplier like NINGBO INNO PHARMCHEM CO.,LTD. is a strategic decision for product innovation and consumer satisfaction.
