Tetrakis(Hydroxymethyl) Phosphonium Sulfate Solution(THPS, 75%)

Tetrakis(Hydroxymethyl) Phosphonium Sulfate Solution (THPS, 75%) is a high-performance, environmentally friendly quaternary phosphonium salt biocide. This 75% aqueous solution appears as a clear, colorless to slightly yellowish liquid with a faint acidic odor. As a broad-spectrum microbiocide, THPS effectively controls bacteria, algae, fungi, and sulfate-reducing bacteria (SRB) across a wide pH range. Its unique chemistry enables rapid biodegradation into harmless byproducts after use, making it an ideal choice for environmentally sensitive applications. Our THPS 75% solution offers excellent water solubility, a low freezing point (below -20°C), and long-term storage stability. It is widely recognized as a superior alternative to traditional glutaraldehyde and isothiazolone-based biocides in oilfield water treatment, cooling water systems, pulp and paper manufacturing, leather tanning, and textile flame retardant applications.
