Quality Control

Our Disodium Lauriminobishydroxypropylsulfonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and heavy metals are available upon request to support your quality assurance protocols.

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 may affect quality.
