Latex- friendly sunscreen or sunblock?

Advice
#1

It is widely known that the oils in sunscreen, sunblock, and tanning lotions will cause quick and unrepairable damage to latex gaskets on drysuits and dry tops.

Are there any particular brands that are made with chemicals that won’t damage latex?

#2

Oil free
There are many oil free sunscreens available.

So…
do we know for a fact that this does not contain any chemicals that harm latex, or is it just “oil free”, whatever that means?
