Pyrithione Zinc is widely used as an antimicrobial and antifungal active ingredient in cosmetics and personal care products (notably anti-dandruff shampoos); it serves as a biocide in paints and coatings to inhibit mold and microbial growth on surfaces; it is employed as an antimicrobial additive in polymers and plastics to improve microbiological stability; it appears in household cleaning products for microbial control; in textiles, it is applied as an antimicrobial finish to reduce odor and maintain fabric hygiene.
