clear deodorant stick with water and glycerin!
Here's a recipe I found from Hallstar for this kind of deodorant!
CRYSTAL CLEAR HYDROPOLYOLIC DEODORANT STICK BASE
6% sodium stearate
0.7% fragrance oil
Heat the glycerin and water to 85˚C, then add the sodium stearate. Mix until melted and clear. Add the emollient and remove from the heat. When cooled to lower than 50˚C, add the triclosan and pour into deodorant containers.
I used PPG-3 benzyl ether myristate (aka Crodamol STS) as my 2% emollient and I added 1% fragrance oil (again, I used Yuzu from Brambleberry as a light and airy scent, but you could use anything you wanted) and removed 1% from the water amount. It felt really lovely on my skin, very glidy and light.
One small problem, though. About two days later, the container was filled with all the water the glycerin had attracted from the air (I didn't put the cap on as I was taking pictures of it and simply forgot!) and it was slimy. It really didn't help using water in this recipe as well! This is one of the huge down sides of using glycerin as your polyol in a deodorant, especially if you're including water - it's a very hygroscopic (water attracting) ingredient. Propylene glycol does this as well, but not as much as glycerin.
Most of the recipes you'll see for a deodorant contain propylene glycol for this very reason. If you don't like propylene glycol, you can try yesterday's recipe with glycerin in its place, but be warned you might end up with a watery slimy mess!
