I am looking to create an antiperspirant roll-on product. I have experimented with high concentrations of `Aluminum Chlorohydrate` (ACH) in two formats: an emulsion and a clear solution. * **Emulsion:** The product is unstable under accelerated conditions. * **Clear Solution:** I am unsure which texture modifier to use that can withstand very high concentrations of ACH. I would like advice in 3 areas: 1. For the `Emulsion` format, which `Emulsifier` should be used to stabilize high concentrations of ACH? 2. For the `Solution` format, which texture modifier is compatible with this active ingredient? 3. Between using `ACH` alone, `Aluminum Zirconium` alone, or a combination of both, which option provides the best sweat suppression?
