"Sun Protection - New SPF Methods"
The Chair of ISO TC 217 (Cosmetics) explains the newest alternative SPF methods.

About the Webinar

For many decades researchers have looked to replace the gold standard ISO 24444, which has a skew towards UVB and a complete lack of visible light. This blind spot can be filled in by transmission measurement in vitro or by in silico calculation. The hybrid diffuse reflectance method (HDRS) combines in vitro and in vivo data, while not generating an erythema. To give all alternative methods a fair evaluation, an industry-wide group is forming Consortium ALT-SPF. As co-initiator of ALT-SPF and chair of ISO TC 217, Mr. Osterwalder will bring us up to speed on their findings.
