Quality Control

Our N(Alpha)-Lauroyl-L-Arginine Ethyl Ester Acetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure it meets stringent specifications for cosmetic and pharmaceutical applications. Certificates of Analysis (COA) documenting identity, purity, and related substances are provided with every shipment to guarantee traceability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place 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 can affect stability and performance.
