Product Overview
Sodium lauryl sulfate LR is a high-purity anionic surfactant widely used in laboratory settings for its excellent emulsifying, wetting, and detergent properties. This laboratory reagent grade compound is synthesized through sulfation of lauryl alcohol, ensuring consistent quality and performance in critical applications. The powder form allows for easy handling and precise dosing, making it ideal for formulations requiring controlled foaming and solubility. Its molecular structure provides strong surface activity, enabling effective dispersion of oils and organic compounds in aqueous solutions. The LR grade designation guarantees minimal impurities, ensuring reliable results in analytical and preparative procedures. Sodium lauryl sulfate functions as a micelle-forming agent, which is particularly valuable in biochemical assays and protein studies where controlled denaturation is required. The compound maintains stability across a wide pH range, though optimal performance is typically observed in neutral to slightly alkaline conditions. As a standard laboratory reagent, this product undergoes rigorous quality control to meet established purity benchmarks, with typical assays exceeding 90% active content. The 500g packaging provides an economical bulk option for frequent users while maintaining the integrity of the product through proper storage conditions.
FAQs
