ZOOM #29: Sweat resistance is a key factor in sunscreen protection by Helioscreen (now Weneos)

To ensure a good protection performance, sunscreens should not only protect against UV rays but also offer some resistance to environmental elements. Sweat is produced to ensure the thermoregulation of the body, during physical activity or in the case of high temperatures. In those conditions, customers are usually also exposed to sunlight, so the protection must be intact. In the last few years, HelioScreen developed a new sweating simulator to assess the in vitro sweat resistance of a sunscreen product. Using molded PMMA plates, products can be exposed to an artificial sweat solution under specific conditions. Then the percentage of sweat resistance is obtained by calculating the ratio of the Sun Protection Factor (SPF) before and after the exposition.
