In order to guarantee a certain level of repeatability and reproducibility, standards require stable, standardized environmental conditions for the evaluation of sun protection. The UV protection of certain products may be affected by variations in temperature or humidity.

Today’s consumers are increasingly attracted by suncare products that can be applied at any time (in the mountains, on excursions, etc.) and in all conditions of use (tropical, polar, temperate, etc.).

In order to determine and justify the effectiveness of the product to be protected under extreme conditions, WENEOS has developed an exclusive in vitro method based on the comparison of the sun protection factor (SPF) in extreme conditions of temperature and humidity. The aim is to guarantee consumers UV protection whatever the season or location.

We can assess the sun protection of your products in full compliance with official methods, or claim the properties of your products through exclusive tests developed by WENEOS.
