Talcum powder is made from a mineral called "talc" that is ground to a fine consistency. Talcum powder is commonly used to care for rashes and chafing on children and adults, as well. The powder is sold in many grocery and drugstores and is fairly inexpensive. However, some individuals may wish to create their own talcum powder at home to reduce costs and control the substances used.
Combine ½ cup baking soda and ½ cup cornstarch. Sift the cornstarch first if necessary, to break up any clumps.
Add 1 cup of arrowroot powder.
Add a few drops of fragrant essential oil, if desired.
Mix the ingredients well and store them in a sealable container.
