After rinsing with tap water and drying, the bleaching rate was calculated according to the following formula.
- the reflectance was measured with a ND R—10 DP manufactured by Nippon Denshoku Industries Co., Ltd. using a 46 nm filter. (Preparation of force-leaked cloth) After removing the solid content of retort curry (house curry Marche) made of house food with a mesh, the resulting liquid was heated until boiling. Cotton gold cloth # 2 0 0 3 was immersed in this solution and boiled for about 15 minutes. Removed from the fire, left for about 2 hours and allowed to stand at room temperature. Then, the cloth was taken out and the excess adhering liquid was removed with a spatula and allowed to dry naturally. Then, it was pressed and used for the experiment as a 10 cm 10 cm test piece.

- the organic peracid production rate is higher than that of granules, and the bleaching performance evaluation results shown in Table 7 show that the bleaching performance is also high. From this, the bleaching activator granulated product of the present invention has improved solubility by adding the component (b), and as a result, the organic peracid production rate contributing to clothing bleaching is increased. It is presumed that the bleaching performance is improved.
- the bleaching activator granulated product of the present invention is remarkably improved in solubility at a low temperature, and can improve the bleaching performance and reduce the unsettled residue of the bleach activator granulated product.
