| 摘要 |
A particulate additive is reported which is an intimately blended mixture of a precursor, a stabilizing agent and a dispersing agent. The precursor is a quaternized ammonium or phosphonium substituted carbonic acid ester. A C4 or higher organic acid having at least one carboxylic group, such as lauric acid, or a solid inorganic acid, such as potassium bisulphite, is required as the stabilizing agent. Various alkoxylated fatty alcohols, fatty acids or alkylated phenols are utilized as the dispersing agent. These particulate additives are employed as adjuncts in bleaching-detergent compositions. |
