Tetrakis Hydroxymethyl-Phosphonium Sulfate, THPS Biocide, THPS Chemical

Properties:

Tetrakis hydroxymethyl-phosphonium sulfate (THPS) is a kind of environmental anti-microbial reagent. It’s characterized by its low solidity point and fine stability. THPS biocide can be reserved for a long time and easily dissolve in water.

Tetrakis hydroxymethyl-phosphonium sulfate is a new environmental pesticide with high efficacy, low toxicity, and low rudimental. THPS chemicals can kill germ and aquatic plants. In 1995, the US EPA (Environmental Protection Agency) ratified it with zero toxicity and awarded it the US Green Chemical prize.
