<Evaluation of fading suppression of clothing under the influence of daylight>

Evaluation of the fading suppression of the garment by the influence of sunlight was performed using a xenon lamp which irradiates light with a spectral distribution similar to sunlight. Specifically, it was performed as follows.

[Pretreatment]

Using 1 tank washing machine (product name: CW-C30A1-H1 type, manufactured by Mitsubishi Electric Corporation), for 1 kg of Printstar T-shirt (short sleeved heavyweight T-shirt with round neck, color "025 green", manufactured by Toms Corporation) , Using a tap water at 50 ° C., and using a commercially available cleaner top (manufactured by Lion Co., Ltd.) at a standard use concentration (20 g of cleaner top, 667 ppm, and bath ratio 30 times based on 30 liters of tap water), After repeating the operation of washing and dehydration of "Dehydration for 5 minutes" by 2 degrees, "Dehydration for 15 minutes after 5 minutes of dehydration" repeats the operation of rinsing and dehydration 5 times, and then hangs at room temperature Dried.

After drying, using a color difference meter (product name: Spectrophotometer SE2000T, manufactured by Nippon Denki Industries Co., Ltd.), the illuminometer in the xenon long life fade meter, which will be described later, for the color (E value) of the initial state, is printed Star T. The four positions of the same position with respect to the shirt, that is, the position where the distance between the illuminometer and the print star T-shirt were 25 cm, were measured at a size (in-circuit) of 3 cm in diameter.

Separately, 1 kg of B. V. D undershirts (round-neck short sleeved T-shirts, part number G0134TS) were subjected to pretreatment such as pretreatment for the Print Star T-shirts.

[Washing, xenon lamp irradiation processing]

Using a mini fully automatic washing machine (product name: JW-Z23A, manufactured by Haier) as the washing machine, 12 liters of tap water at 25 ° C of water temperature was collected in a tank of the mini fully automatic electric washing machine, and 10 g of the cleaning composition of each example was dissolved, respectively, in total 600 g Clothes (four pieces of Printstar T-shirts subjected to the pretreatment described above, 3.5 pieces of BV D socius) were put in and washed in a standard course.

Xenon long life fade meter (model: FAL-25AX-HC, B, EC, Suga Tester Co., Ltd. product) which extracts clothing after irrigation and irradiates light which has a spectral distribution similar to sunlight, (hereafter "xenon" Lamp ”, and the cumulative amount of irradiance per turn is 2500 kJ while maintaining the distance from the xenon lamp at 25 cm at a temperature of 40 to 50 ° C. and a relative humidity of 50% and rotating around the xenon lamp. The said 4 places were irradiated so that it might become / m <2>.

After this washing and xenon lamp irradiation treatment was repeated five times, the color difference meter was used to measure the state of the four colors on a printed Star T-shirt, and the average value thereof was determined. The average value and the initial state of E The difference with the value (ΔE value: degree of fading) was calculated.

In addition, the washing and xenon lamp irradiation processing of 5 times of accumulation radiated illuminance of 2500kJ / m <2> correspond to about 1 day of sun drying in summer generally.

How small is the ΔE value in comparison with this (In Examples 1 to 15 and Comparative Examples 1 to 5, which are granular cleaning compositions, what percentage of the effect of suppressing fading was obtained with respect to the degree of fading of Comparative Example 1)? In Examples 16 to 24, which are liquid detergent compositions, and the examples of Comparative Examples 6 to 8, how many percent of the effect of inhibiting fading was obtained on the degree of fading of Comparative Example 6 was evaluated based on the following evaluation criteria. It was done. The evaluation results are shown in Table 1 and Table 2.
