In our announcement of 18.8.21, we reported on our participation in an international round robin test whose primary objective was to test Hybrid Diffuse Reflectance Spectroscopy (HDRS) as an alternative to the previous gold standard for sun protection factor measurement, ISO 24444.
We completed the round robin test in February this year. We have now sent our results to the statisticians of the ALT-SPF consortium for evaluation.
Final results of the interlaboratory comparison and their publication are of course still pending, but in order to give interested customers the opportunity to get to know the procedure and to use it as a screening method for formulation selection, we are already offering the HDRS method.
The method offers real added value for study participants and manufacturers. It is non-invasive and can accelerate product development. Our Customer Relations & Sales team will be happy to inform you about the method and advise you on how to conduct screening studies, which can be carried out with up to 8 products on a small group of subjects.
