Quality Control

Our Poly(Oxy-1,2-Ethanediyl), .Alpha.-2-(1-Oxooctadecyl)Aminoethyl-.Omega.-Hydroxy- is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, ethylene oxide content, acid value, and 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, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may affect product quality.
