Cosmetics Europe – The Personal Care Association published the recommendation N26 for alternative in vivo SPF test including the in vitro SPF method double plate.
Cosmetics Europe “strongly recommend that CE members (and the test laboratories with whom they work) familiarise themselves with them (SPF in vitro double plate) as soon as possible so that, prior to the publication of the final ISO standards, they may be considered as alternative SPF in vivo tests to ISO24444:2019.”
What good news! 😄🔬
For the more curious, here is the article of Cosmetic europe: https://urlz.fr/hRb4
Waiting for the publication of the ISO 23675 norm (in progress), at HelioScreen, we already propose this SPF in vitro double plate since many years.
