Quality Control

Our Dehydrated Castor Oil, Glycerin, Phthalic Anhydride, Soybean Fatty Acids Polymer is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance characteristics such as acid value, viscosity, color, and solids content. Certificates of Analysis (COA) documenting these specifications 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 area at room temperature (15-25°C/59-77°F). This material is light-sensitive and should be stored away from direct light. As it is easily oxidized, containers should be kept tightly sealed when not in use to minimize exposure to air. Keep away from heat sources and open flames.
