In December 2010, the European Standardisation Organisation (CEN) published the Standard UNI EN ISO 24444:2011 Cosmetics ‐ Sun protection test methods ‐ In vivo determination of the sun protection factor (SPF). This test method replaces the earlier reference method (International Sun Protection Factor Test Method (2006) as updated in 2006 by the European, Japanese, American and South African industry) as specified in the EU recommendation from 2006. The UNI EN ISO test method is considered as the reference method within the EU. Cosmetics Europe therefore recommends cosmetic manufacturers to use this standard to determine the Sun Protection Factor (SPF). The standard UNI EN ISO 24444:2011 (January 2011 edition) is the official version of the European standard EN ISO 24444 (November 2010 edition). Our company performs the in vivo determination of the sun protection factor (SPF) according to this method. Please do not hesitate to contact us for any clarification or further information.
