DETERGENT COMPOSITIONS HAVING A POLYPHOSPHATE SALT

摘要

The present invention relates to detergent compositions having polyphosphate salt. More particularly, it relates to detergent composition comprising a mixed polyphosphate salt containing an alkali metal and a magnesium counter ion, having the formula: MxMg((n-x+2)/2)PnO3n+1, whrein n is an integer from 3 to 25, x is an integer from 1 to n, and M is an alkali metal. A process for forming a mixed polyphosphate salt is also provided.
