I am an R&D and Quality Control Director at a dermatological skincare manufacturing facility. We are currently evaluating new botanical preservatives and anti-microbial agents for our new formulations. It is critical for our strict regulatory compliance that the raw materials we purchase are rigorously verified. I need to understand the exact procedures for confirming Totarol HPLC tested purity and how those results should perfectly align with standard COA benchmarks provided by the manufacturer.
