For the most part, I pay little heed to the silicone I use in formulation. Typically I am using just a kiss of dimethicone to make sure soaping does not raise it's ugly head, and 1-2% of D5 to make for a nice feel, and usually 1% Polymethylsilsesquioxane, just to make sure things feel good.
In the deodorant cream I am currently working on...my silicone levels have exceeded any of my past adventures. I think getting into the neighborhood of 6% or so. The formula has an emulsification system of a little gum, a little Zen, and a split of 165 and Montanov L, with a kiss of Sodium Stearoyl Glutamate for good measure.
With the 6-7% silicone level, do I need to use any specialty emulsifier, with an affinity for the silicones?
Glycerol oleate keeps jumping in and out of the formula...depending on my mood...
