Quality Control

Our Calcium Isobutyrate is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and composition. We can supply material compliant with relevant standards such as FCC (Food Chemicals Codex) for food-grade applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
