Quality Control

Our Calcium Dihydroxide is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. Product quality is verified against relevant industry specifications, including Food Chemicals Codex (FCC) for food-grade material and other industrial standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your specific requirements.

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) and must be kept in its original, sealed packaging to prevent caking and degradation due to absorption of atmospheric carbon dioxide (CO₂).
