Bio of the developing chemist

Julian Hewitt is a leading expert on the formulation, development and testing of sunscreen products, with over 25 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. Julian was promoted to ICI’s Science Ladder as the company’s sun care Technical Expert, and from 2002 served as an adviser to Uniqema’s Sales & Marketing, Product Development, and Technical Service teams. He continued in this role after Uniqema was purchased by Croda in 2006.

During this time, Julian 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 2011 and 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 over 40 papers and posters at conferences in venues across the World, and in particular has been a frequent speaker at the Florida SCC Sunscreen Symposium and the London Sun Protection Conference. In 2008, he won the Lester Conrad Award for the Best Paper at the Australian Society of Cosmetic Chemists annual conference in Surfers Paradise, Queensland. He has also written or co-authored more than 30 articles and 6 book chapters on formulating sunscreens, in-vitro SPF testing, and nanotechnology.
