UVA/SPF: Upgrade your Test Strategy for Regulatory Compliance

Julian Hewitt is a leading expert on the formulation, development and testing of sunscreen products, with over 20 years of experience in this field.
Julian graduated from Oxford University in 1988 with a BA Honours Degree in Chemistry. After graduating, he joined Tioxide, working on new product development from 1988 to 1991. In 1991, he joined Tioxide's Solaveil Business, as Applications Research and Technical Service Manager for physical sunscreen products. He remained with the Solaveil business as it moved from Tioxide to ICI Performance Chemicals, then to Uniqema when the latter was formed in 1999, and finally to Croda, who purchased Uniqema in 2006.
During this time, Julian became recognised as one of the leading global experts in sun care. He represented Uniqema / Croda as the main customer technical focus for sun care products, developed and delivered training programmes for both internal and external audiences, and guided the development and launch of innovative new sun care ingredients.



Julian left Croda in October 2010 and has recently formed JPH SunCare Technologies, providing technical consultancy services, regulatory advice, and training to manufacturers of UV protection products and suppliers of ingredients used in such products.
Julian has presented papers and posters at over 30 conferences in venues across the World, and has written or co-authored more than 20 articles and 4 book chapters on formulating sunscreens and in-vitro SPF testing.
