INTEROX TO BUILD SODIUM PERBORATE PLANT IN US

The Interox Group said it will build a new sodium perborate monohydrate plant in the United States and expand existing facilities in the United Kingdom, Belgium, West Germany and Italy because of increasing demand for the chemical in laundry detergent formulations.

Interox America will construct a new 45 million pounds a year plant at its Deer Park, Texas, complex, where it currently produces hydrogen peroxide and sodium percarbonate. The unit is scheduled to start up in early 1992.Unspecified expansions in Europe will begin to come on stream by the end of this year.

Sodium perborate is a solid peroxygen bleaching compound used in detergent powders. While most detergents in the past used tetrahydrate formulations, a global shift away from using phospate in detergents has necessitated the replacement of sodium perborate tetrahydrate with sodium perborate monohydrate, according to Leibert Danielson, a company vice president.

Demand for sodium perborate in Europe is approximately 1 billion pounds a year, while demand in North America may be as high as 100 million pounds a year, Mr. Danielson said.
