Water, soap, and other personal cleansing solutions aren't likely to cause a problem, but formaldehyde and other potent holding tank chemicals may.
I used a fresh tank as a gray tank for several years with no known ill effects.
(Sink water only, no chemicals except bleach, used to disinfect and keep odors at bay.)
