Quality Control

Our N(Alpha)-Lauroyl-L-Arginine is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets stringent specifications for cosmetic and pharmaceutical-grade ingredients. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability, consistency, and compliance with relevant standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product quality.
