I really can't make a recommendation on how much BTMS and cetyl alcohol to use. My test mixture is no different than the plain babassu + mag hydroxide mix as far as being more glidy, and that was my point when adding these ingredients.
My current idea is that it's mainly the powder that is making the mixture so non-glidy. I'm getting good odor control at 30% Mag hydroxide -- as good as when I used 50% -- so that's a step in the right direction.
So the melt point has gone up, the odor control is just as good, but glidy-ness ... not so much. This is a work in progress, definitely.
Edit: This is the recipe I trialed --
Mg(OH)2 powder 30 gram
Babassu 55 gram (melt temp 76 F)
Cetyl alcohol 14 gram (melt temp 120 F)
BTMS 14 gram (melt temp 140 F)
Fragrance 0.5 gram
The melt point of this mix is below 125 F -- I'm guessing maybe 110 to 120 F.
This amount will fill up one regular oval deodorant tube (the kind most commercial antiperspirants are sold in) plus one mini oval deo tube (about 0.4 ounce (12 gram) capacity)
