isthis so hopefully you can see list of nasties below. Basically avoid anything that starts with cyclo!
In terms of foundations: many of the Kiko range (they have a few shops but see online - and currently have a great sale) do not contain cyclo-silicones - make sure you check the ingredients list - but the ones I know are ok are:
The cream foundation, the 2 in 1 foundation and the mat one.
In terms of a primer: Maybelline baby skin does not contain either.
Beware as it is in a lot if body lotions, serums and hair conditioners too.
I would not worry about having some drinks... a lot of women get pregnant drunk after all
