Hello I Was Cleaning My Trash Can And I Had

Hello I was cleaning my trash can and I had a cup of water with Clorox that I had drained inside the trash can to clean it. My daughter then reached for the cup and drank from it, but it was foam. I rinsed her mouth and made her drink a half bottle of water. Should I be worried? She seems fine, like I said she only drank a little bit of foam.
