Type of powder is a term used to describe a variety of substances that are finely ground into a powder. TALC (4 letters) and talcum (6 letters) are two examples of type of powder. TALC is a mineral composed of hydrated magnesium silicate, while talcum is a powder made from TALC. TALC is used in a variety of products, including cosmetics, paint, paper, and plastics. Talcum is commonly used as a personal hygiene product, as it absorbs moisture and helps reduce friction.
