Jenna,

There are a couple of factors on the disinfectant front, the biggest one being the new VOC regulations that are coming down at the end of this year that will significantly limit how much alcohol you can have in your product.  There are ways around the regs but it's not particularly straight forward.

The second reason is the stigma around contact time vs. time to dry.  Even with 15% IPA most wipes have a 3-5 min contact time which means in order to be compliant you need to rewet the surface because with so much alcohol, the surface is usually dry in about 30 seconds.

For hand sanitizers it's about skin care. Alcohol is really drying and if the expectation is to use a sanitizer every time you walk into or out of a patient's room, that's really hard on the skin.
