Tinosorb M
Hello everyone
What is your take on Tinosorb M for sunscreen? And are titanium and zinc a thing of the past? I spoke to some formulators who said that Tinosorb doesnt leave a white cast; and is not an endocrine disruptor.I did my research as usual but no longer know who i should believe as the industry is no unregulated and dont know what sources of information is the best.So i like to speak to all of you as you are experts and scientists.
Thanks

The industry is for sure regulated. There might be some areas for improvement, but there are regulations. The best sources are as usual, independent studies published in peer-reviewed journals, info from regulatory agencies and technical books (Cosmetic Science and Technology comes to my mind, as well as books from CRC).
Tegarding Tinosorb M, to my knowledge, it hasn’t been approved as a sun filter in the USA…but if you’re in Europe, that should be fine. It’s mostly used as a booster for other filters, although it can act as a primary filter. TiO2 and ZnO are good part of a robust sun filtering system, but are not enough to give full and high protection. Mixing them with organic filters is a better approach.

If you are formulating products for distribution outside the USA, Canada, and Australia/NZ, then Tinosorb M is a good UVA/UVB absorber. It also stabilizes avobenzone well. As my esteemed colleague mentions however, it has never been approved by the US FDA for use here. Bummer!
