Is there a paraben-free zinc oxide (not TiO2) sunblock that doesn't separate?

I like Eco Logical quite a bit, but just like Badger brand, after a few weeks the oil separates. If I forget to work the tube before squeezing I get a spurt of clear oil all over everything. Yuk. Even if I do work the tube, it doesn't mix back in readily, so I get very thin oil with a little bit of sunblock in it.

I'm afraid if I stored it in the fridge it would be rock hard and impossible to apply. But maybe I should do that, since most of the time I apply it from my little half-contact-lens-case anyway
