Never use Talcum powder on a baby. It causes inflammation of the lungs if it is inhaled and can stop or impair breathing. I really would suggest using a Cornstarch based powder on a child. In fact, you can use straight Corn Starch if you are looking to save money. For an adult, if you are using this on yourself or a teen in your home is using it, just a regular bath powder would be fine as long as you are careful not to inhale it. I personally prefer the Johnson and Johnson baby powders for both myself and my children. My favorite for myself is the lavender scented one. They are talcum free. Every regular bath powder that I have looked at contains talcum powder. I don't think there is as much harm to it for an adult, but for a baby you are using it so close to their face and the chance of them inhaling it is greater. Most baby powders are talcum free, but occasionally (usually in dollar stores) I find talcum in the ingredient list.
