In December 2024, two Sun Protection Factor (SPF) test methods were published by the International Standard Organisation (ISO) Central Secretariat. They are now officially recognised as ISO Standard methods.
“These methods are the Double Plate Method (DPM) (ISO 2375) developed by Cosmetics Europe member experts and the Hybrid Diffuse Reflectance Spectroscopy (HDRS) Method (ISO 23698),” explained technical regulatory and international affairs director at Cosmetics Europe, Gerald Renner.
“Both are SPF test methods alternative to the currently used in vivo International Standard (ISO 24444:2019) method.”
