Quality Control

Our production of Butanedioic Acid, Polyisobutenyl Derivs., Dipotassium Salts adheres to stringent quality management protocols. Each batch is characterized for critical parameters including active content, saponification value, viscosity, and metal content to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications 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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
