China and India are the leading exporters of Thiourea dioxide, accounting for the majority of global shipments, while the United States, Germany, and South Korea represent the largest importers. Thiourea dioxide prices have remained relatively stable amid steady cross-border flows, with no major price volatility observed in recent trade records. Export volumes from China have grown modestly over the past two years, while Indian exports have plateaued, and U.S. imports have increased slightly—reflecting continued industrial demand in textile and pharmaceutical applications.
Thiourea dioxide is a white to off-white crystalline solid with no significant odor and low volatility; it decomposes before melting, typically above 130 °C. It is classified as an organic sulfur compound and a reducing agent, structurally derived from thiourea. Industrially, it serves primarily as a mild, selective reducing agent in textile dyeing—especially for vat and sulfur dyes—and as a stabilizer or catalyst in polymerization processes. Its applications are concentrated in the textile, dye, and specialty chemical sectors, where it functions in controlled reduction reactions without damaging sensitive substrates or functional groups.
Convenient reagent for the reduction of ketones to secondary alcohols.Thiourea dioxide is an effective bleach when used alone or when used after hydrogen peroxide in a full bleaching process (Duffield, 1986; Cegarra et al, 1988). Bleaching with thiourea dioxide is not common practice but it is effective when used alone, and the process compares favorably with hydrogen peroxide bleaching. A formulation can include a commercial thiourea dioxide product, wetting agent and EDTA sequestering agent. Reductive bleaching is carried out at pH 7.0 at 70°C for 60 min (Duffield, 1986).
