Is baby powder like alum powder?

No, baby powder and alum powder are not the same. Baby powder, typically made from talc or corn starch, is used for preventing diaper rash and absorbing moisture on the skin. Alum powder, on the other hand, is a type of chemical compound often used in cooking, water purification, and as an astringent. While both may have uses in personal care, their compositions and applications are quite different.
