Compositions, systems and method for in situ generation of alkalinity

摘要

The invention discloses compositions, methods and systems for generating alkalinity in situ. The compositions, methods and systems relate to the use of a silver decomposition agent to catalyze the decomposition of a dilute peroxygen source providing highly alkaline cleaning compositions in situ. Methods of cleaning are also disclosed.

主权项

1. An industrial, household, health care and/or vehicle hard surface cleaning composition comprising:
a peroxygen source having a concentration between about 0.01-10% and a pH between about 7-10; and a silver decomposition agent having a concentration from about 0.5 ppm to about 10%, wherein said decomposition agent catalyzes the decomposition of said peroxygen source to form hydroxide anions sufficient to increase the pH by greater than about 3; wherein said pH is suitable for industrial, household, health care and/or vehicle hard surface cleaning.
