Sodium pyrithione (SPT) is the sodium salt of 2-mercaptopyridine-1-oxide, a broad-spectrum biocide with strong activity against bacteria and fungi at low use concentrations. It is widely used as an antidandruff agent in shampoos, a preservative in paints, and an antimicrobial additive in plastics and textiles. SUNCHEM supports international buyers with Sodium Pyrithione (SPT) sourcing from qualified Chinese producers, with quality documentation, export coordination, and logistics support.
