In the realm of surfactants, two names frequently appear: Sodium Lauryl Sulfate (SLS) and Sodium Lauryl Ether Sulfate (SLES). While both are anionic surfactants with cleansing properties, understanding their differences is crucial for formulators, especially when considering ingredients for personal care products or detergents. As a chemical supplier, we often guide our clients through these distinctions to ensure they select the optimal ingredient for their specific application. Our focus today is on the widely used 70% SLES.

The primary distinction lies in their chemical structure. SLES, unlike SLS, undergoes an ethoxylation process, which involves adding ethylene oxide. This addition modifies the molecule, generally resulting in a surfactant that is milder to the skin and eyes. This enhanced mildness makes SLES a preferred choice for products that have prolonged contact with the skin, such as shampoos, body washes, and facial cleansers, where irritation is a significant concern. While SLS is highly effective, its potential for irritation is higher, leading many manufacturers to opt for SLES when seeking a gentler alternative.

Beyond mildness, SLES typically exhibits better foaming and stability in hard water compared to SLS. This translates to a richer lather and consistent performance, even in areas with challenging water conditions. These properties contribute to a superior user experience, a key factor in consumer product success. For businesses aiming to buy personal care ingredients or high-performance detergent raw materials, the choice between SLES and SLS often hinges on the desired balance of cleansing power, mildness, and foaming characteristics.

When you buy SLES 70% manufacturer direct, you are investing in a versatile and well-tolerated surfactant. For formulators, understanding these differences allows for targeted product development. Whether you need the potent cleansing of SLS or the milder, more luxuriant lather of SLES, choosing the right ingredient from a reliable SLES supplier in China is key. We offer premium SLES at competitive SLES price points, ensuring you can achieve your formulation goals with confidence.
