There is a brand of Sunscreen wipes called Shady Day. They are wonderful! They carry individually packaged wipes as well a pillow packs (which are like small versions of baby wipes packs).
They smell nice, the towelette is soft and there is enough sunscreen for 2 kids on each towelette. There are no funky ingredients. I've used these the past few years. They travel well and are great to have so you're not spraying everyone around you.

I think they're great. Compared to other brands with very thin towels, these are really nice and thick.
