Talcum Powder (Talc)
Talcum Powder is a naturally occurring mineral composed primarily of hydrated magnesium silicate. It is known for its softness, absorbency, and lubricating properties. Talc is widely used in cosmetic, pharmaceutical, industrial, and consumer products due to its ability to absorb moisture, improve texture, and provide a smooth, silky feel. The powder form allows easy dispersion and application across diverse sectors.
