Quality Control

Our (Z)-Poly(Oxy-1,2-Ethanediyl), .Alpha.-(Carboxymethyl)-.Omega.-(9-Octadecenyloxy)-, Sodium Salt is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for critical parameters such as acid value, saponification value, ethylene oxide content, and active matter. Certificates of Analysis (COA) documenting purity and performance characteristics are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial opening to prevent absorption of atmospheric moisture, which can affect product performance.
