Baby powder is primarily used to absorb moisture and reduce friction on skin, traditionally applied during diaper changes to help prevent diaper rash in babies. Beyond this, it is used by adults for various purposes such as keeping feet dry, preventing chafing, and even as a makeshift dry shampoo to absorb excess oil from hair roots[2].
Common uses include:
- Absorbing moisture to prevent skin irritation or chafing in humid areas, both for babies and adults[3].
- Reducing friction on the skin, particularly in areas prone to sweating or rubbing, like thighs and underarms[3].
- Making it easier to remove sand from skin and hair after a beach visit[1].
- Serving as a dry shampoo to absorb oil from the scalp between washes[1][2].
- Preventing sweat stains on clothing and keeping feet or shoes dry[1].
- Used during waxing or shaving to create a barrier that reduces irritation[1].
- Helping maintain the condition of household items, like keeping pool inflatables from sticking together or preventing irons from snagging delicate fabrics[1].
Modern safety guidelines recommend talc-free powders for babies, as inhalation of talc can be harmful, and advise using such powders sparingly and carefully. Alternatives like cornstarch-based powders are considered safer, but most pediatric experts suggest limiting the use of powders in infant care altogether in favor of frequent diaper changes and barrier creams[2].
