I came up with a deodorant recipe I absolutely love, but I keep having the issue of the baking soda making small little clumps in it after a few days. I use arrowroot powder and only 2% of the recipe is baking soda since it irritates my skin otherwise. I know it is the baking soda because my other recipe is the exact same just without the baking soda, and it doesn’t get the clumps. I make sure to mix it really well and add slowly. Maybe I am just not mixing well enough? I love that it works but I can’t sell it with the clumps. Thanks for any advice you can give!
