EDITED WITH ANSWER: Oil degrades rubber! Thanks everyone!

I applied a quick spray of Sunbum spray sunscreen to the parts in both of my daughter’s hair. Within minutes, their rubber hair ties snapped and unraveled from around their hair. They didn’t dissolve, just a clean break. They both had 2 hairties in, and they all snapped multiple times throughout the night as I kept replacing them (I only applied the sunscreen once). I haven’t used new shampoo, the hairties are also not new or too tight and it wasn’t too hot. The sunscreen was the only new thing.

Anyone have any thoughts?
I’m terrified of what I just spray on my babies heads….
