But Purell is not SPNG's "delivery system." And each product that claims to be anti-microbial must be independently tested or use methods/products/solutions that have been approved for such use. Furthermore, i've never read any claim, PR or such that SPNG is using either Purell or any other product approved for use in their particular circumstance. maybe i've missed it. but, certainly someone on this board must know where supporting documentation can be found.
