NINGBO INNO PHARMCHEM CO.,LTD. understands the critical role of selecting the right ingredients for product formulation. When it comes to surfactants, Sodium Lauryl Ether Sulfate (SLES) 70% stands out. But how does it compare to other common surfactants like Sodium Lauryl Sulfate (SLS)?

Historically, SLS was a dominant surfactant due to its powerful cleaning and foaming abilities. However, SLS has a significant drawback: it can be a strong skin and eye irritant. Many studies and consumer reports highlight its potential to strip natural oils from the skin and scalp, leading to dryness and irritation. Furthermore, SLS has relatively low aqueous solubility, which can limit its effectiveness in certain formulations.

SLES 70%, on the other hand, is an ethoxylated derivative of SLS. This modification significantly improves its properties:.

  • Reduced Irritation: SLES is generally considered milder on the skin and eyes than SLS, making it a safer choice for products that have prolonged contact with the body, such as shampoos and body washes.
  • Enhanced Solubility: SLES exhibits better solubility in water, ensuring easier formulation and consistent performance, even in hard water conditions.
  • Superior Foaming: While both create foam, SLES often produces a more stable and luxurious lather, which is a key consumer expectation in personal care products.
  • Cost-Effectiveness: SLES provides excellent performance at a competitive price point, making it an attractive option for manufacturers looking to optimize production costs without compromising quality.

While other surfactants exist, SLES 70% offers a compelling balance of efficacy, mildness, and affordability. For businesses looking to purchase bulk surfactants, understanding these comparative advantages is crucial for developing successful products that meet consumer needs and market trends. This makes SLES 70% a preferred anionic surfactant for a wide range of applications.
