We have bottles of this stationed in various rooms around the house because you're just always going to need one for a toddler (especially when potty training). Our boy was also immunocompromised for about a year and it was a relief to have this option that passed all the lab tests, instead of usuaing a fragranced or alcohol-laden alternative. It was a staple for the hospital bag and used instead of the strong alcohol-based sanitisers that you usually find in the hospitals (so abrasive on the skin). An excellent sanitiser.
