ENHANCED PEROXYGEN STABILITY IN MULTI-DISPENSE TAED-CONTAINING PEROXYGEN SOLID

摘要

Stabilized compositions employing a sequestrant system and a binding system for improving shelf stability and dispensing stability of a solid activated bleach composition are disclosed. The compositions contain a peroxygen source and a catalyst activator which require generation of a peroxycarboxylic acid or other active oxygen sanitizing agent at a point of use. Stabilized compositions employ a sequestrant system including a phosphonic acid and/or dipicolinic acid sequestrant and a binding system comprising an anionic surfactant for a solid formulation of a catalyst activator and peroxygen source to provide shelf stability and dispensing stability for a activated bleach composition. Methods of formulating and use are further disclosed.

主权项

1. A stabilized solid activated bleach composition comprising:
at least one alkaline solidification matrix; an active oxygen source; a bleach activating agent; and a sequestrant system comprising a phosphonate and/or acid thereof; a binding system comprising an anionic surfactant and a cellulose component; wherein the solid composition has less than 1 wt-% water and provides shelf stability at room temperature for at least about one year.
