Quality Control

Our Lauromacrogols are manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. The product is tested against stringent in-house specifications, which may include parameters for identification, assay, ethylene oxide content, and residue on ignition. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance.
