I wasn't sure if you would want to make your own, but this is the one I make. Hubby and I both use it, and I've been super happy with it. I have always had trouble with deodorant's and anti-perspirants, so I decided to try this one after the rave reviews. There was a short adjustment period, where I didn't think it was working (a few days), and then it was over and it's been wonderful ever since. Here it is incase you would be interested.
One thing: it seemed a little too oily as I was making it so I added more cornstarch and a little more baking soda, and it seemed perfect. Well, after packing it into a jar and waiting a day to use it, I realized it really hardens a lot when left to sit. So now it's a little too hard and gets kind of crumbly when I scoop it out....I guess packing it in an old deo stick holder would work the best in this case, so I'll do that next time.
I didn't even think to post that it hardens more after it sits- sorry about that. :) I keep it in a glass jar with a lid and just scoop a bit out everyday and use it like lotion on my armpit. The stuff is amazing, it really is. Glad you liked it. I have family members that want me to make them some, so I think I'll put it in pretty jars and add it to their Christmas gift this year, along with the recipe.
