  Tinosorb S (not approved in the US yet). But is better not using octinoxate with AVO even with stabilizers.

  Hi Eli,

  You can try the photostabilizers from Hallstar. For example you can use Solastay S1 (INCI: Ethylhexyl Methoxycrylene), Solastay P1 (INCI: Polyester 25), Polycrylene (INCI: Polyester , and Hallbrite PSF (INCI: Undecylcrylene dimethicone).

  Hope this helps!!!!!!!!!!!!!!!!!

  Yes it helps a lot, thanks @cosmochem and @pma ! What do you think about micro encapsulated avobenzone? Would it really be more stable ?

  Hello again! I was starting with sun care some months ago and after reading a lot of opinions about Avobenzone + EHMC (octinoxate) i can’t seem to understand why if there is such a unstable mix people keep using it everywhere. I know they are not used alone but with octocrylene stabilizing avobenzone, and sometimes even small amounts of EHMC are used.. like 0.5% does it actually makes sense? Maybe i have still a lot to learn, but every time i read more about the subject i get more confused. !!.. and anyways the products i check in supermarkets and everywhere they use that wonderful threesome of UV filters: BMBM, EHMC and OCR.. Thanks !
