Sodium Lauryl Sulfate (SLS), also known as Sodium Dodecyl Sulfate (SDS), is a vital chemical compound with extensive applications, particularly in the detergent and industrial sectors. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing clarity on the technical specifications that define the quality and performance of our SLS products, catering to both detergent and cosmetic grades.

Understanding the precise characteristics of SLS is crucial for formulators and manufacturers to ensure optimal product outcomes. Our SLS is available in both powder and needle forms, with key parameters meticulously controlled to meet industry demands. The appearance is typically described as white or light yellow powder, or white or yellowish needles, ensuring it does not clump. This visual consistency is the first indicator of product quality.

A critical measure of SLS quality is its active content, which for our products, is specified as ≥94.4% for the powder form and ≥88.0% for the needle form. This high active percentage signifies efficient cleansing and foaming capabilities. Furthermore, stringent limits are placed on undesirable components. Unsulfated Matter is kept at ≤1.0% for powder and ≤1.5% for needle form, indicating a pure surfactant. Similarly, the combined sodium chloride and sodium sulfate content is controlled to ≤2.5% (powder) and ≤5.0% (needle form), minimizing impurities that could affect performance or stability.

Moisture content is another vital specification, maintained at ≤3.0% for powder and ≤0.5% for needle form, ensuring product stability and shelf-life. The pH value of a 1% aqueous solution is typically maintained between 7.5 to 10.5 for powder and 7.5 to 12.5 for needle form, indicating appropriate alkalinity for formulation compatibility. Whiteness is also monitored, with powder at ≥80, and specific limits on heavy metals like Lead (Pb) ≤10-15 mg/kg and Arsenic (As) ≤3-10 mg/kg, underscoring our commitment to safety and purity.

For industries relying on SLS, sourcing from a reputable sodium lauryl sulfate powder supplier like NINGBO INNO PHARMCHEM CO.,LTD. ensures access to materials that meet these precise technical requirements. Whether for use as a powerful anionic surfactant foaming agent in detergents or as a key ingredient in personal care items, our products are engineered for excellence. Clients seeking reliable detergent grade SLS K12 will find our specifications meet their needs for high performance and purity.

In essence, the technical specifications of Sodium Lauryl Sulfate are not merely data points; they are indicators of product quality, efficacy, and suitability for diverse applications. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing SLS that adheres to these high standards, supporting innovation and success across the industries we serve.
