The Cardno ChemRisk View
SOT 2015 - Q&A with Cardno ChemRisk Scientists Part I: Grace Anderson
A group of researchers from Cardno ChemRisk will attend the 2015 Society of Toxicology's Annual Meeting in San Diego, California from March 22-26. At SOT, we will present recent research during posters and presentations.
Between today and the start of the conference, the Cardno ChemRisk View will feature a series of presentations, as described by staff. First up is Grace Anderson from our San Francisco office:
What is the title of your presentation?
Exposure Assessment of Lotion, Stick, and Spray Sunscreen Application
What was the scope of your research?
In this study we evaluated the amount of sunscreen applied to the skin across three prominent application methods: lotion, spray, stick. We also investigated the relationship between sunscreen application and other behavioral or demographic factors.
What did you find?
The 52 volunteers in this study applied different amounts of sunscreen depending on the application method. Participants applied the greatest thickness of sunscreen when using a spray product and the smallest when using a stick product.
For lotion, there was a significant difference in application thickness between age groups of the volunteers. For spray, there was a significant difference in application thickness between skin reaction groups.
What are the next steps/what other research is needed?
It would be informative to repeat this type of survey on a larger scale and with different product formulations.
