pH-controlled release of detergent components

摘要

A process of washing textiles is presented involving the delayed release of ingredients from a detergent composition. The process involves first dissolving the detergent in water resulting in a pH below 8, slowly dissolving the coating on a coated alkalizing agent to raise the pH to above 8.5, and dissolving the polymeric acid coating on a detergent ingredient, due to the pH above 8.5, to release the ingredient into the wash water.
