As a lead formulation chemist, I am currently developing a clear, water-based anti-acne serum and a soothing lotion using natural plant-based preservatives. Before officially requesting R&D samples for our lab trials, I need to review the detailed technical specifications of the raw material. What is the precise industry-standard COA benchmark for high-quality cosmetic Totarol extract in terms of physical appearance, active assay purity, chemical solubility profiles, and strict microbiological safety limits?
