At NINGBO INNO PHARMCHEM CO., LTD., we believe in empowering our clients with comprehensive knowledge about the chemicals they use. Sodium Laureth Sulfate (SLES 70%) is a widely utilized anionic surfactant, and understanding its chemical structure is key to appreciating its versatile performance benefits across numerous applications.

The chemical formula for SLES is R-O-(CH₂CH₂O)n-SO₃Na, where 'R' represents a fatty alcohol chain, typically C12-C14 alkyls (lauryl and myristyl groups), and 'n' denotes the average number of ethoxy units. In SLES 70%, the 'n' value is typically around 2, hence the common designation '2EO'. This specific structure is crucial: the ethoxy chains provide water solubility and contribute to milder properties compared to its non-ethoxylated counterpart, Sodium Lauryl Sulfate (SLS). The sulfate group provides the anionic charge, which is fundamental to its surfactant activity.

This molecular design directly translates into SLES 70%'s exceptional performance. The hydrophilic ethoxy groups and the hydrophobic fatty alcohol chain allow it to effectively reduce surface tension, enabling superior cleaning, emulsifying, and wetting capabilities. These properties are essential for removing oils and dirt from surfaces and skin. When you buy Sodium Laureth Sulfate online, you are acquiring a chemical engineered for optimal interaction at interfaces.

The presence of the ethoxy chains also contributes to SLES 70%'s lower irritation potential. This makes it a preferred choice for sensitive skin applications, such as shampoos and body washes, where mildness is paramount. The SLES 70% price reflects the controlled manufacturing process required to achieve this specific ethoxylation level and ensure purity, offering a balance of efficacy and gentleness.

As a leading Sodium Laureth Sulfate supplier China, NINGBO INNO PHARMCHEM CO., LTD. meticulously controls the manufacturing process to ensure consistent 'n' values and minimal by-products like 1,4-dioxane, which is important for safety and regulatory compliance. Understanding the chemical nuances helps formulators fine-tune their products, whether for personal care, household detergents, or industrial applications. We provide the quality raw materials that form the backbone of effective chemical formulations.
