The Environmental Working Group (ewg.org) has a database (www.cosmeticsdatabase.com) that rates the safety of chemicals and ingredients in a variety of products, including sunscreen and insect repellant. It might give you some ideas of what the safest products are. EWG also did a report last year on which sunscreens are most effective (http://www.cosmeticsdatabase.com/special/sunscreens/summa....
I agree with other posts that the California Baby SPF 30 sunscreen works great, but it is a bit thick and you really have to rub in it well.
