Finally I can present my new Sunscreen! SPF50+ UVA 45 (very high UVAI protection!).
It contains: OMC+AVO in Microbeads; TinosorbM+S, TiO2 (Micronized), ZnO (non-micro), Enzulizole, Ethylhexyl Tirazone. + VitaminC (5% stable form), VitE (1%).
It is a highly photostable sunscreen that stays on the surface of the skin with very high containt of inorganic filters. Maximum UVB/UVA protection till 383nm. UVAI (360-400nm) esp. between 380-400nm, protection that is very difficult to achieve. It is good in this SS.
(Would add that neither the EU nor the AU standard requires any protection over 370nm! AU:360nm)
This sunscreen has better protection in the UVAII + I than inorganic SS agents. UVB protection of this SS cannot be achieved by any combo of inorganic SS agents!
Cosmetically very much acceptable. Used Microbeads: OMC+AVO in silicone oil which gives a beautiful semi-matt finish to the skin. And it does not sink into the skin! Stayes on the surface of the skin all day giving the skin a beautiful sheen even without make-up!

I am very proud of this sunscreen which I have been working on for almost 20 years (finally there are sunscreen agents and silicone oils to make it possible to come true!)
The only question remaining is how to market it outside of Oslo, Norway in the near future.

The only thing surprises me though is why don't big cosmetic companies use microbeads more in their SS!
PS: For comparision attaching a profile of the SS I am currently working on: SkinScience SPF50+ UVA 25(inorganic filters) good UVB/ high UVAII+I prot.
Very whitening though :(
Used: TiO2 (micronized), ZnO (1/3 micronized + 2/3 non-micro). (Used a matte-silicone base for less shine.) Photostable, not requred to reapply it every 2 h. Highly tolerated.
