<Evaluation of the effect of preventing urine odor transfer>

(1) Preparation of clothes with urine odor

Underpants of post-incontinence cotton pajamas were recycled by 10 families with persons in need of care. The objects of recovery are clothes that have been used for more than one year, have a urinary incontinence frequency of more than 3 times per week, and the urine odor has not been removed even after ordinary washing. After recovery, let the team members select the odor intensity as 0 or 1 according to the sensory evaluation of the following (3), and then select the characteristic "very unique and very depressing odor" from the clothes with a large amount of p-cresol. 4 households' worth of clothes. This was cut into a square of 4 cm on one side and used as a test cloth.

(2) Cleaning by composition

This test cloth was subjected to a washing test as follows. As the cleaning tester, a vertical decontamination machine (Terg-O-tometer) (manufactured by UNITED STATES TESTING, Inc.) was used. The cleaning solution was prepared by adding the liquid cleaning composition for fiber products in Table 2 and Table 3 to 900 mL of water so as to have 833 ppm, and stirring for 30 seconds. 900 mL of the cleaning solution, 5 pieces of the test cloth, 5 pieces of wet artificially soiled cloth (manufactured by the Laundry Science Association), wet artificially soiled cloth (trade name "EMPA116") were put into the cleaning tester. , manufactured by EMPA) 5 pieces, 5 pieces of cotton shirts (LL size, manufactured by B.V.D. Co., Ltd.) cut into a square with a side of 4 cm as the urine odor transfer evaluation cloth, and washed knitted cloth at a bath ratio of 20 times. Wash at 120 rpm and 15°C for 20 minutes. Second, move to a two-slot laundry After dehydrating for 1 minute in a machine (manufactured by Mitsubishi Electric Corporation: product name CW-C30A1-H1), rinse in 30 L of tap water (15° C., 4° DH) for 3 minutes, and dehydrate again for 1 minute.

(3) Sensory evaluation of urine odor transfer

Let each group member take 5 pieces of urine odor transfer evaluation cloth of 1 household amount as a group, and smell the odor of 4 groups, evaluate the odor intensity in 6 stages based on the following evaluation criteria, and use each group member's It is carried out by calculating the average score of 4 groups of odor intensity. A higher score for odor intensity indicates a weaker odor. Moreover, the deodorizing effect was evaluated by the following reference|standard based on the average score (average score of 6 persons) of sensory evaluation.

(Evaluation of Odor Strength)

5 points|pieces: There is no strange smell at all.

4 points: Odor is sensed to a barely perceivable level.

3 points|pieces: Odor is weakly sensed.

2 points|pieces: Odor is sensed slightly strongly.

1 point|piece: A strange smell is strongly sensed.

0 points|pieces: Odor is felt strongly.

(evaluation criteria)

◯: The average score of the sensory evaluation is 4.0 or more.

Δ: The average score of the sensory evaluation is 3.0 to 3.9.

x: The average score of sensory evaluation is 2.9 or less.

<Example 19>

Furthermore, add 1% by mass of antibacterial agent (chloroalkyl (carbon number 12) trimethyl Ammonium, manufactured by Lion Akzo (Lion Akzo, trade name "Arquad (Arquad) 12-37W")), except that, in the same manner as in Example 1, a liquid detergent composition for fiber products was obtained. a/b=2.5, b/c=3333, a/c=8333, pH=3.2.

The urine odor removal effect and the oxygen absorption suppression effect were evaluated in the same manner as in Example 1, and both were ⊚. Furthermore, the antibacterial property was evaluated as follows, and it was ⊚.

<Example 20>

Then add 0.1% by mass of antibacterial agent (diclosan (diclosan) (4,4'-dichloro-2-hydroxyl diphenyl ether), trade name "TINOSAN (TINOSAN) HP100", BASF (BASF) company Manufacture), except that, in the same manner as in Example 1, a liquid detergent composition for fiber products was obtained. a/b=2.5, b/c=3333, a/c=8333, pH=3.2.
