Quality Control

Our Cyclosiloxane is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification. Certificates of Analysis (COA) are provided and can be tailored to meet specific customer or regulatory requirements, including those relevant to personal care and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is between 15°C and 25°C.
