Triclosan is a somewhat ubiquitous gram + antimicrobial, but it seems to be getting a bad wrap lately. I'm not particularly concerned about if these opinions are backed by solid science or not (although I do believe that overuse of a single antimicrobial is not a good thing), whats important is that selective people may not want this ingredient in their products. That said, are there good alternatives to Triclosan out there (?) that have most of the following properties;
- Anti-microbial activity against gram + bacteria on the skin (anti-odor)
- Relatively low cost/concentration used ratio
- Low odor (microbial itself does not stink)
- Doesn't sound extremely scary on label
- Stable around non-ionic surfactants
- Effective
OK, I know that's probably a tall order, but I am open to suggestions. I look forward to your comments.

Chlorhexidene does have drawbacks. The one that I hear about on a regular basis is in laundry for care homes. If you are in a region where sodium hypochlorite bleach is used in laundry on a regular basis (Mainly the US and Canada) this can interact with Chlorhexidene residues and give a rather nasty stain that won't come out in the wash.
We also discovered that it's activity as a deodorant was much stronger (and lasted longer) than Triclosan had in such products like foot care.
However, it could give some complexes with some other actives in solutions. For instance, adding Chlorhexidine to the thymol solution resulted in white cloudy complexes.
FDA NEWS RELEASE
Most of the data I've seen seems to indicate that they're no better at reducing bacteria than products without (esp with respect to triclosan), that's even before you start looking at whether they have any clinical benefit. Sure you can kill 99.9% of bacteria, but what's the point if that 99.9% of bacteria is generally harmless.
Now that we've sufficiently derailed gfeldman's original post... is Silverion 2400 (formerly known as Tinosan) an alternative to triclosan? I know it's used in a lot of deodorant formulations. Lotioncrafters has the tech sheet for it: http://www.lotioncrafter.com/tinosan-sdc.html
Yes, the Siverion is light sensitive, like I mentioned in my post above, and yes it is expensive. These are some of the reasons I have not used it. However, it is a viable option for the original poster's purposes in certain circumstances--especially if he is aiming to please a particular clientele willing to pay a little more for ingredients they "approve."
