Talc is available in various grades based on purity, particle size, and intended use. Cosmetic grade is highly purified and safe for skin contact. Pharmaceutical grade meets strict purity for medicinal applications. Industrial grade suits plastics, ceramics, paper, and rubber but may have a wider particle size range. Food grade talc is used as an anti-caking agent. Some grades undergo surface treatment to improve dispersion or compatibility with other materials. Selecting the correct grade ensures talc performs properly and meets safety requirements.
