Additional Information

My name is Ethan Alden-Danforth and I am a senior executive in the cosmetic and OTC personal care industry with over 15 years of experience in R&D and manufacturing. I hold a PhD in Organic Chemistry from Johns Hopkins University and currently serve as Vice President of R&D for a cosmetic contract manufacturer, where I oversee formulation development, raw material sourcing, product safety and testing, regulatory compliance, and process engineering across cosmetic and OTC drug product lines. I provide expert witness services for plaintiff and defense counsel in state and federal litigation involving cosmetic and OTC personal care products. My litigation work encompasses product liability and class action matters, false advertising and labeling disputes, FDA and MoCRA compliance failures, PFAS and heavy metals contamination, microbial and chemical adulteration, GMP violations, contract manufacturing disputes, recalls, and adverse event investigations. I have experience reviewing technical and regulatory documentation, preparing expert witness opinion reports, and providing deposition testimony. My qualifications are grounded in hands-on operational experience rather than purely academic research. I have direct experience managing cGMP manufacturing operations, implementing FDA and Health Canada regulatory programs, overseeing OTC drug registrations, directing stability and safety testing programs, and managing raw material qualification and supplier auditing. Prior to my current role, I spent six years at L'Oréal USA in R&D leadership positions, where I directed the technical development for one of L'Oreal's largest brand eye makeup portfolios and led product launches that generated over $1.6 billion in combined domestic and international sales. I hold two issued US patents in cosmetic formulation and delivery systems. I have testified before the Vermont Health and Welfare Committee as a scientific subject matter expert on legislation regulating chemicals used in cosmetics including heavy metals and PFAS. My experience spans the full product lifecycle — from concept and formulation development through commercial scale-up, GMP manufacturing, regulatory filing, and post-market surveillance — giving me the breadth of knowledge necessary to analyze liability and causation across the full range of cosmetic and OTC personal care disputes. I serve clients nationwide and am available for case consultation, record review, expert report preparation, and deposition and trial testimony.
