Talcum powder is a cosmetic product made from finely ground talc, an extremely soft mineral. One of its most common uses is in baby care, with some parents using it to reduce rashes and irritation from diapers. It can also be used on adults to prevent chafing and rashes, and some people have come up for creative uses for this product, like sweeping it into the cracks of wooden floors to prevent them from squeaking. This product's primary role is as a moisture absorber. By sucking up moisture from the surrounding area, talcum powder keeps the skin dry. This can reduce the risk of rashes and chafing from sweat, urine, and other bodily secretions, and it also increases comfort in hot weather. Many babies find it very comforting, since they do not have any control over when their diapers are changed.
