Description

Lubrol Wx is a high-purity, non-ionic surfactant belonging to the polyoxyethylene ether class, widely recognized for its excellent solubilizing and emulsifying properties. Its primary value lies in its ability to effectively stabilize and disperse biological membranes and proteins, making it a critical reagent in biochemical and pharmaceutical research. This product is essential for laboratories and manufacturers in the life sciences, detergent formulation, and specialty chemical synthesis industries. Lubrol Wx CAS NO 11138-41-3 is a trusted component for ensuring consistent and reproducible results in complex analytical and production processes.

Application

• Biochemical Research & Membrane Protein Solubilization: A key reagent for the isolation, purification, and stabilization of integral membrane proteins, including receptors and enzymes, without denaturation.
• Cell Lysis & Organelle Isolation: Used in buffer formulations for gentle cell disruption and the isolation of functional subcellular components like mitochondria and microsomes.
• Pharmaceutical Formulation: Serves as a solubilizing and stabilizing agent in the development of injectable and topical drug formulations, particularly for hydrophobic active pharmaceutical ingredients (APIs).
• Diagnostic Assay Development: Employed in immunoassays (e.g., ELISA, Western Blot) and diagnostic kits to maintain antigen integrity and reduce non-specific binding.
• Industrial & Institutional Cleaning: Acts as a potent surfactant and emulsifier in specialized detergent systems for laboratory glassware, medical devices, and precision equipment.
• Cosmetic & Personal Care: Functions as a mild emulsifier and stabilizer in high-performance skincare and haircare products.

Quality Control

Our Lubrol Wx is manufactured under strict quality management systems to ensure batch-to-batch consistency and high performance. Each lot is subjected to rigorous analytical testing, including assessment of critical parameters such as ethylene oxide content, hydroxyl value, and critical micelle concentration (CMC). A comprehensive Certificate of Analysis (COA) detailing purity, identity, and physical specifications is provided with every shipment. We adhere to relevant ISO guidelines and can support compliance documentation for research and cGMP applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent absorption of atmospheric moisture. Keep away from strong oxidizing agents.
