Sodium Lauryl Polyoxyethylene Ether Sulfate (SLES) is a workhorse ingredient, widely appreciated for its surfactant properties in everything from luxurious shampoos to industrial cleaning agents. For procurement managers and formulators, understanding how to buy SLES effectively is key to achieving optimal product performance and cost efficiency. As a prominent manufacturer and supplier of SLES in China, we aim to guide you through the essential considerations when making your purchase.

Understanding SLES Specifications: Purity and CAS Numbers

When you search to buy SLES, you'll commonly encounter CAS number 9004-82-4, which denotes Sodium Lauryl Polyoxyethylene Ether Sulfate. This number is crucial for ensuring you're sourcing the correct chemical compound. However, it's important to note that SLES is often a mixture of molecules with varying degrees of ethoxylation (the number of ethylene oxide units attached). This variation, represented by 'n' in the formula CH3(CH2)11(OCH2CH2)nOSO3Na, can influence properties like foaming and irritation. Commercial SLES typically has an average ethoxylation degree, with laureth-2 and laureth-3 sulfates being common.

Purity is another critical factor. While the active matter content typically ranges from 68-72%, variations can impact performance. Always check the technical data sheet from your supplier. For cosmetic applications, minimizing impurities like 1,4-dioxane and ethylene oxide is paramount, and reputable manufacturers will adhere to strict quality control measures.

Key Considerations for Purchasing SLES:

  • Application-Specific Requirements: Are you formulating a gentle facial cleanser, a high-foaming laundry detergent, or an industrial degreaser? The intended application will dictate the necessary grade and purity of SLES. For personal care, focus on low-irritation grades. For industrial tasks, robust cleansing and foaming might be prioritized.
  • Supplier Reputation and Reliability: Choosing a reputable manufacturer and supplier is crucial for consistent quality and timely delivery. Look for suppliers with established track records, transparent quality control processes, and clear communication channels. Sourcing from China offers potential cost advantages, but due diligence in supplier selection is essential.
  • Price vs. Value: While competitive pricing is always a consideration, don't compromise on quality. The overall value derived from a high-purity, consistently performing SLES will often outweigh a slightly lower upfront cost, especially in sensitive applications like cosmetics. Requesting quotes from multiple trusted suppliers is a good practice.
  • Technical Support and Documentation: A good supplier will provide comprehensive documentation, including Certificates of Analysis (CoA), Material Safety Data Sheets (MSDS), and technical support to help you integrate the SLES into your formulations effectively.
