In the world of chemical formulations, surfactants play a pivotal role, dictating the efficacy and sensory experience of countless products. Among these, Sodium Lauryl Ether Sulfate (SLES) 70% stands out as a remarkably versatile and widely adopted ingredient. At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing high-quality chemical solutions, and understanding the nuances of SLES 70% is crucial for leveraging its full potential.

What is SLES 70%?

Sodium Lauryl Ether Sulfate (SLES), with its CAS number 68585-34-2, is an anionic surfactant widely recognized for its excellent cleaning, emulsifying, and foaming properties. It is often preferred over its counterpart, Sodium Lauryl Sulfate (SLS), due to its milder nature and reduced potential for skin irritation. This makes SLES 70% a preferred choice for manufacturers focused on personal care products, where gentle yet effective cleansing is paramount. The '70%' designation refers to its active matter content, indicating a highly concentrated and effective form of the surfactant.

The Manufacturing Process and Sourcing

SLES is typically synthesized through the ethoxylation of lauryl alcohol, which can be derived from natural sources like coconut or palm kernel oil, or from petrochemical feedstocks. This ethoxylation process adds ethylene oxide chains to the lauryl alcohol, which are then sulfated and neutralized to form the sodium salt. At NINGBO INNO PHARMCHEM CO.,LTD., we prioritize sourcing materials that align with quality and sustainability standards, ensuring that our SLES 70% meets rigorous performance criteria. This process results in a cost-effective detergent raw material that offers remarkable performance without a prohibitive price tag.

Key Properties and Benefits of SLES 70%

  • Excellent Detergency: SLES 70% effectively breaks down oils and grime, making it ideal for cleaning applications.
  • Superior Foaming: It produces a rich, stable lather, which is a key sensory attribute consumers associate with effective cleaning in products like shampoos and body washes.
  • Emulsification: SLES 70% aids in mixing oil and water components, crucial for stable product formulations.
  • Mildness: Compared to SLS, SLES 70% is less likely to cause skin irritation, making it suitable for sensitive skin products.
  • Water Solubility: It dissolves readily in both hard and soft water, ensuring consistent performance across different water conditions.
  • Biodegradability: SLES is considered biodegradable, aligning with the growing demand for eco-friendly cleaning ingredients.

Applications Across Industries

The versatility of SLES 70% is evident in its widespread application. In the personal care sector, it's a staple in shampoos, body washes, liquid soaps, and toothpaste, providing the desired cleansing and foaming experience. For household cleaning, it's a primary component in dishwashing liquids, laundry detergents, and surface cleaners, appreciated for its grease-cutting power and affordability. Beyond these, SLES also finds use in industrial settings as a lubricant, dyeing agent, and degreaser in the textile, leather, and petroleum industries.

Addressing Common Concerns

While SLES 70% is generally considered safe and effective, it's important to address common consumer concerns. The myth that SLES causes cancer is unfounded; extensive research by regulatory bodies has affirmed its safety for use in cosmetic and personal care products. Similarly, concerns about environmental impact are mitigated by its biodegradability. The key is proper formulation and usage. At NINGBO INNO PHARMCHEM CO.,LTD., we ensure our SLES 70% is produced responsibly, and we advocate for its correct application to maximize benefits while minimizing any potential risks.

By understanding the science and applications of SLES 70%, manufacturers can effectively leverage this powerful surfactant to create high-performing, consumer-preferred products. Its unique combination of efficacy, mildness, and cost-effectiveness solidifies its position as an indispensable ingredient in modern chemical formulations.
