In June 2012, the European Standardisation Organisation (CEN) published the Standard EN ISO 24443:2012 Cosmetics – Sun protection test methods – In vitro determination of sunscreen UVA photoprotection. This standard test method replaces the earlier reference method (Colipa Guidelines - Method for in vitro Determination of UVA protection, 2011). The EN ISO test method is now considered as the reference method within the EU. Cosmetics Europe therefore recommends cosmetic manufacturers to use this standard to determine the UVA Protection Factor and the Critical Wavelength. Our company performs the in vitro determination of sunscreen UVA photoprotection according to this Standard Please do not hesitate to contact us for any clarification or further information.
