Ingredient in Sunblock that causes rash if your allergic to it?

Question

If anyone has had a allergic reaction to sunblock and knows the ingredient or chemical in there that caused it, can you please tell me? That way I can buy sunblock without that ingredient and see if a rash does not appear. I am trying to rule out what is causing the skin rash. Thanks.

There's actually hypoallergenic sunblock that you can use.
