pH-controlled release of detergent components |
摘要 |
A process for 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 pH 8, slowly dissolving the coating on a coated alkalizing agent to raise the pH to above pH to above pH 8.5, and above pH 8.5 the polymeric acid coating on a detergent ingredient dissolves, releasing the ingredient into the wash water. Also presented is a detergent composition for delayed bleaching of 1 to 40 percent by weight of a coated bleaching agent having a coating which dissolves slowly in water irrespective of the pH value, 0.5 to 15 percent by weight of a bleach activator coated with a polymeric acid, and 0.1 to 40 percent by weight of an acidifying agent. The process results in a delayed release of bleaching in the wash cycle.
