Adducts of polyamino acids, alkali metal pyrophosphates and peroxides

A process for preparing an adduct comprising the steps of:

• (a) dispersing or dissolving about 0.1 wt. % to 99.0 wt. % of at least one alkali metal pyrophosphate and 0.1 wt. % to 99.0 wt. % of at least one compound selected from the group consisting of polyamino acids, proteins, and any combinations thereof in an aqueous peroxide solution at a temperature in the range of from about 4° C. to about 90° C. to obtain a solution or a slurry;
• (b) stirring the resultant solution or slurry of step (a) from 1.0 rpm to 10,000 rpm and at a temperature of about 4° C. to about 90° C.;
• (c) drying the resultant solution or slurry of step (b) at cold, room or higher temperature to form a dried adduct;
• and
• (d) milling the dried adduct obtained in step (c) to obtain adduct with the desired particles size distribution
