           | Asbestos, for example, is much less dangerous in drinking
           | water than in the air because the lubrication provided by

           |

           | diluting agent that reduces the probability of the benzene
           | sticking around in the body. Since there is a lot less volume
           | of blood flow in the tiny capillaries near the skin and hand
           | sanitizer is designed to evaporate, there's a far higher risk
           | of carcinogenic concentrations of benzene building up,
           | especially around cuts or lesions.
           | 
           | It's very plausible that a few mL of sanitizer with ppb
           | concentrations of benzene can accumulate in small microliter
           | pockets of tissue with concentrations in the 10s or 100s of
           | ppm if continually applied throughout the day for months on
           | end. Throw in the rapid pace of reproduction of skin cells
           | and that's a legitimate cause for concern.
           | 
           | [1] last I looked, it wasn't well studied in humans, but
