Light and sun exposure testing of cosmetic products is best performed using xenon arc lamp devices which can provide solar simulation of both direct and window glass filtered daylight, or artificial store light. The
SUNTEST CPS+ and
XLS+ benchtop exposure instruments are the most widely used for this application, although any of Atlas’ xenon arc instruments can be used.
The
SUNTEST series can be optionally equipped with a SunCool air chiller system to decrease test specimen temperature, important for thermally labile materials such as those containing waxes.
For SPF (Sun Protection Factor) in vitro testing to ISO 24443 Determination of sunscreen UVA photoprotection in vitro and the COLIPA 2011 in vitro UVA method, the optional SunTray and SunCool for the
SUNTEST CPS+ is recommended.
