Quality Control

Our Potassium 2-(2,5-Dihydroxy-4-Octadecylphenyl)-2-Methylpropanesulphonate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing key parameters such as assay, moisture content, and heavy metals is provided and available upon request 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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance and stability.
