Caused a rash

I bought this thinking it would be the safest option for my daughter, instead it gave her a pretty horrible rash. I washed it off her and the rash remained for 4 days before it went away. I wasn’t entirely sure it was from the sunscreen so I did a patch test on her leg and it did the same thing to her. She normally doesn’t have reactions to skin care products so I’m not sure what was in this to cause that but I wouldn’t recommend it.
