3/4 cup arrowroot powder or cornstarch
1/4 cup kaolin clay
2 tsp zinc oxide powder
Sift together (the kaolin has a tendency to clump) and put half the mixture in a clean glass jar. Get a cotton pad and put your choice of fragrance or essential oils on it. I have a ton of 1 mL sample vials of indie perfumes, so I usually just dump one of those on. Put the cotton pad in the jar, add the rest of the powder, close the lid tight, and shake it up. Let it sit for a couple days, shaking it every so often. Pour the powder into a container of your choice, removing the cotton pad when it shows up. I got a metal shaker canister from a kitchen supply store. Make sure it has a reasonably airtight lid if you’re going to keep it in the bathroom.
I got my zinc oxide powder from Amazon, a small packet will last a long time. It acts both as a deodorizer and a skin soother. A lot of people use baking soda, but that can irritate sensitive skin.
I got my kaolin from a bath & body supply company online (
here is a list of suppliers in various countries). I also make bath bombs and lotion bars so I was already paying to ship other stuff. Pretty sure you can get that on Amazon too, but beware of counterfeits. Apparently people counterfeit freaking clay of all things.
