Powder for baby is a product used to keep babies dry and comfortable. The most common type of powder for baby is TALC, which is a soft mineral composed of hydrated magnesium silicate. TALC is often used in baby powder, body and facial powders, and other cosmetic products. It is also used as a lubricant and to absorb moisture. TALC is generally considered safe for use on babies, but it should be used with caution and kept away from the baby's face.
