John offers something few regulatory consultants can: seven years working inside Australia's industrial chemicals regulator (NICNAS, now AICIS), so he understands not only the rules but how the regulator evaluates a submission. A chartered chemist and toxicologist, he advises across cosmetics, listed medicines, medical devices and industrial chemicals including GHS classification, SDS drafting and risk assessment, and is a leading sunscreen specialist. He has delivered GMP refresher training in sunscreen manufacture, runs clients' twice-yearly internal audits, accompanies TGA auditors, and sits on the CS-042 committee behind the AS/NZS 2604 sunscreen standard.
