Then, the present inventors examined what factors caused the temperature rise.

As a result, as is apparent from Reference Example 3 shown in Table 1, the temperature of the bleaching detergent composition mainly increases due to the heat of self-decomposition of the persulfate and / or hydrogen persulfate. As is clear from the above, the temperature of the bleaching detergent composition significantly increases in the presence of the persulfate and / or hydrogen persulfate and the fragrance, and the fragrance emits smoke due to the increased temperature in the presence of the fragrance. We found that it became easier, and focused on this. The examination was performed as follows.
Preparation of Bleach Detergent Composition (Comparative Example 1, Reference Examples 1 to 11) In Table 1, the bleach detergent composition (Comparative Example 1 and Reference Examples 1 to 11) totals 100 g in weight ratio shown in Table 1. In this manner, each component was mixed, and the mixture was tableted to give 25 g per tablet. Tableting was performed by putting 25 g into a cylindrical die and punching down the upper punch with a hydraulic pump (surface pressure: 900 kg / cm ² ). As a result, a composition in the form of a tablet (about 16 cm ³ / tablet) was obtained.

Next, one nonwoven fabric was laid on a stainless steel wire mesh in a thermostat set at 70 ° C., and one tablet of the composition was sealed thereon with an aluminum package (16 cm × 13.5 cm, internal space: about 30 cm ³ ). And left for 1 hour. After standing, the surface temperature of the aluminum package containing the composition was measured.

  The temperature was measured using a radiation thermometer (IT-314, thermocouple combined type, manufactured by AS ONE Corporation).

  The presence or absence of smoking was visually observed.

Test example 1
1. Preparation of Bleach Detergent Composition According to Tables 2 and 3, bleach detergent compositions (Examples 1 to 23) and comparative bleach detergent compositions (Comparative Examples 1 and 2) were produced.

  Specifically, the components of the bleaching detergent compositions of Examples 1 to 23 were mixed in the proportions shown in Tables 2 and 3 so that the total amount would be 100 g, and 1 tablet would be 25 g in the same manner as described above. Manufactured by tableting.

  Further, comparative bleaching detergent compositions of Comparative Examples 1 and 2 were produced in the same manner as in Example 1 except that the weight ratio of the components was changed.

These were all effervescent tablets.
2. Evaluation of temperature rise and fuming The temperature rise and the presence or absence of fuming were evaluated in the same manner as described above.
3. Results The results are shown in Tables 2 and 3.

表２及び３から明らかなように、実施例１〜２３においては温度上昇が抑制され、また、発煙も認められなかった。これに対して、比較例１及び２では著しい温度上昇が認められ、かつ発煙も認められた。

As is clear from Tables 2 and 3, in Examples 1 to 23, a rise in temperature was suppressed, and no smoke was observed. On the other hand, in Comparative Examples 1 and 2, a remarkable temperature rise was observed, and smoking was also observed.

  From this, it was found that even when a persulfate and / or hydrogen persulfate was used in combination with a fragrance, the temperature rise could be effectively suppressed by coexisting them in a specific range. Further, the bleaching detergent compositions of Examples 1 to 23 were all in the form of tablets, in which heat was easily accumulated, that is, heat was easily generated by self-decomposition of persulfate and hydrogen persulfate. In addition, the weight was as large as 25 g per tablet, but despite this, the rise in temperature could be suppressed. In addition, even in the case where the content of the fragrance, which contributes to the rise in temperature and smoke, is relatively large, the rise in temperature was effectively suppressed in this test.

  Although not specifically shown in the results, any of these bleaching detergent compositions provided the desired bleaching / cleaning effect.

Here, the degree of bleach washing was evaluated as follows. A 3 cm square black tea-stained cloth (EMPA167, manufactured by Nippon Shokubai Co., Ltd.) was prepared, and the color difference of the stained cloth was measured at three points using a colorimeter (CR-300, manufactured by Minolta) (washing). Previous color difference ΔE). Next, the end of the stained cloth was fixed with a clip, this was set in a 2 L beaker, and 2 L of tap water was introduced so that the stained cloth was immersed (the height from the bottom to the water surface was about 15 cm). One tablet of the bleaching detergent composition was put into this beaker so as to be located at the center of the bottom, and left for 30 minutes. The bleaching detergent composition used had foaming properties, and the arrangement of the contaminated cloth was determined when the contaminated cloth was approximately 1 cm above the container bottom and close to the container wall, that is, the effect of the foam generated by the bleaching detergent composition. Was located in a small place. Thereafter, the contaminated cloth was taken out, rinsed thoroughly with tap water, and dried at room temperature (25 ° C.). Then, the color difference was measured at three points in the same manner as described above (color difference ΔE after washing). The bleaching rate was calculated by the following formula.
Bleaching rate (%) = ((color difference ΔE before washing) − (color difference ΔE after washing)) × 100 / (color difference ΔE before washing)
From the results, according to the bleaching detergent composition, on a hard surface or cloth such as a toilet bowl, a drainpipe, a bathtub, a water tank, a sink, a basin, a washing tub, tableware, a water bottle, a pot, a vase, etc. It was understood that the bleaching washing effect was obtained.

Although not shown in the results, the desired bleaching power was observed in each of the bleaching detergent compositions of Examples 1 to 23. Here, the foamability was evaluated as follows. 2 L of water at 4 ° C. was poured into a beaker having a volume of 2 L, and one tablet (25 g) of the bleaching detergent composition was added thereto. Immediately after the tablets were completely dissolved, the height of foam from the water surface was measured. When the height was 1 cm or more, the evaluation was ◎, when 0.5 cm or more and less than 1 cm, ○; when 0.1 cm or more and less than 0.5 cm, Δ;
Formulation Example In the same manner as in Example 1, bleaching detergent compositions were produced at the ratios shown in Table 4 below. In each case, a rise in temperature is suppressed, no fuming is observed, and a desired bleaching / cleaning effect is obtained.
