PURPOSE:To obtain a high-density particulate concentrated detergent composition having an improved particle color by mixing a specified detergent system containing a fluorescent dye with a specified potassium salt, sodium chloride and polyethylene glycol. CONSTITUTION:The title detergent composition comprising 30-50wt.% anionic surfactant 40-60wt.% inorganic builder and a fluorescent dye contains 5-25wt.% potassium salt of an anionic surfactant or 2-10wt.% potassium carbonate or potassium sulfate, 0.1-3wt.% sodium chloride, and 0.2-5wt.% polyethylene glycol of an MW of 6000-20000, each based on the composition. In order to ensure a sufficient ability to dye various clothes it is desirable to use a combination of two fluorescent dyes of formulas I and II as the dye. In the formulas, X is formula III or IV and Y is formula V or VI. |
