Description

C16E7 CAS NO 4486-31-1 is a high-purity, non-ionic surfactant belonging to the polyoxyethylene alkyl ether family, specifically a heptaethylene glycol monohexadecyl ether. This compound is valued for its excellent emulsifying, wetting, and solubilizing properties, making it a critical component in formulations requiring precise control over surface activity. It is primarily sought after by researchers and industrial chemists in the life sciences, material synthesis, and specialty chemical manufacturing sectors.

Application

• Biochemical Research & Membrane Studies: A key non-ionic detergent for solubilizing membrane proteins while preserving their native structure and function.
• Pharmaceutical & Cosmetic Formulations: Used as an emulsifier and stabilizer in creams, lotions, and topical drug delivery systems.
• Nanomaterial Synthesis: Acts as a structure-directing agent or stabilizer in the controlled synthesis of nanoparticles and mesoporous materials.
• Analytical Chemistry: Employed in micellar electrokinetic chromatography (MEKC) and as a mobile phase additive in HPLC to improve separation.
• Industrial Cleansers & Detergents: Functions as a surfactant in specialized industrial and institutional cleaning formulations.
• Agrochemical Adjuvants: Enhances the spreading and penetration of pesticides and herbicides on plant surfaces.

Quality Control

Our C16E7 is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by HPLC, verification of critical micelle concentration (CMC), and checks for residual solvents and peroxides, to ensure it meets the high standards required for research and industrial applications. A detailed Certificate of Analysis (COA) is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 water vapor.
