With regard to handling film, using e.g. photo-flo for the final wash/rinse at the end.
To get to grips with what we’re talking about here:
Wetting agent : This breaks the surface tension of water, making drops run instead of stay. This is the basic of any detergent, e.g. dish-soap or normal soap.
Anti static: This is important only if you plan on handling your negatives extensively – truly rub them agains each other and any plastic container. Electrostatic buildup comes from rubbing and separation between materials.
I believe that the dust attracted is minimal and hardly ever a problem in a well kept storage for film-negatives
If you’re very concerned with this, then find a conductive mat to put on your table where you handle sensitive stuff. Make it be electrically grounded via a current limiting resistor to the safety ground in your wall outlet. Keep the srurface clean! This table will be an optimal place not only to handle electrically charged Negatives but also computer parts and other electronics. (More info: look for “ESD-safety“)
Anti-bacterial: Well, again something that shouldn’t be necessary. You’re not touching your negative’s flat sides by fingers normally – do you?
I believe that the use of anti-bacterial compounds is part of the the problems with Penicillin nowadays – see http://en.wikipedia.org/wiki/MRSA
So… in the end; you can actually have the important part by using a dish-soap instad – one DROP is enough.
