Quality Control

Our Ppg-23-Steareth-34 is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as hydroxyl value, ethylene oxide/propylene oxide content, and residual moisture are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent caking or degradation. For long-term storage, consider using an inert atmosphere to minimize oxidation.
