At TRI we are passionate about science. Sharing this passion with our members, industry professionals and the community at large is one of our key aims.
Education
Cutting-edge scientific research and the development of new measurement techniques has been a part of TRI's historical legacy since our inception in 1930. It is still core to our mission today.
Research
In Vitro Sunscreen Testing
The TRI Principles of Skin Measurement Science and Claims course will feature a topic in which TRI is a world-leader: the testing of sunscreen formulations and products using vibrational spectroscopy. The TRI course is an annual event, specifically designed for those involved in the development of new skin care products.
Anti-Aging Claims Testing for Skin
Anyone involved in the development of cosmetic items in recent years will have likely noticed the current trend towards anti-aging, or even reversal of aging, products, with these claims increasingly being used as a marketing tool by beauty companies. However, a question we’re often asked at TRI is “how do you measure anti-aging effects?”.
See You in Australia: TRI Exhibiting at IFSCC Congress in Perth, Sept. 28th – Oct. 1st
To some of our member companies and clients in Asia and Oceania, Princeton can seem a very long way away. The good news is that Dr Larry Senak (Principal Scientist, Bio-Substrates) and Dr Paul Cornwell (Director, Business Development) will be present at the IFSCC Congress in Perth at Booth 40.
Jessica Presented Work at the ISBS in Lyon, 10–12 June, 2026
At the ISBS, Jessica gave a talk titled “Spectroscopic Clinical Evaluation of Next-Generation Sunscreen Performance: Assessing UV Filter Beyond SPF in Realistic Global Warming Conditions”, which was based upon work completed at TRI. In this talk, Jessica considered how skin surface temperature during solar exposure can impact upon sunscreen efficacy, which is becoming more important due to climate change.
