Quality Control

Our Linoleic Acid is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as purity, fatty acid profile, and peroxide value. Our quality commitment aligns with cGMP principles where applicable, and we can support compliance requirements for various industrial and specialty grades.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (e.g., nitrogen) at a controlled temperature of 2-8°C (36-46°F) to minimize oxidation. Keep away from heat, sparks, and open flames. The container must be kept tightly closed in a dry and well-ventilated place.
