As in Example 1, the urine odor removing effect and the oxygen gas absorption suppressing effect were evaluated, and both were いずれ. Furthermore, as described below, the urine odor transfer prevention effect was evaluated, and it was o.

<Evaluation of urine odor transfer prevention effect>
(1) Preparation of a clothing having a urine odor Underwear of cotton pajamas was collected after urine leakage from 10 families with a care recipient. The target of collection was clothing that has been used for over a year, has a urine leakage frequency of 3 times or more per week, and has no urine odor even after regular washing. After recovery, according to the sensory evaluation of (3) below, the panelists select 0 point or 1 point of odor intensity, and furthermore, "heavy, heavy, heavy and unpleasant odor" characteristic of clothes with a large amount of p-cresol We selected clothes for 4 families. This was cut into a square of 4 cm on each side to make a test cloth.
(2) Cleaning with Composition The test cloth was subjected to a cleaning test as follows. A Terg-O-tometer (manufactured by UNITED STATES TESTING) was used as a cleaning tester. As a washing | cleaning liquid, the liquid detergent composition for textiles of Tables 2 and 3 was added to 900 mL of water, and the washing | cleaning liquid prepared by stirring for 30 seconds was used. In the washing tester, 900 mL of the washing liquid, 5 sheets of the test cloth, 5 sheets of wet artificial soiling cloth (made by Foundation for Laundry Science), 5 sheets of wet artificial soiled cloth (trade name "EMPA116", made by EMPA) And, 5 sheets of a cotton-skin shirt (LL size, manufactured by BV D. Co., Ltd.) made into a square of 4 cm on one side as a urine odor transfer evaluation cloth and a wash-dressing cloth are introduced, and the bath ratio is 20 Double and wash at 120 rpm and 15 ° C. for 20 minutes. Next, it is transferred to a two-tank washing machine (Mitsubishi Electric: product name CW-C30A1-H1), dehydrated for 1 minute, rinsed in 30 liters of tap water (15 ° C., 4 ° DH) for 3 minutes, and again for 1 minute Dehydrated.
(3) Sensory evaluation of urinary odor transfer Each panelist smells four sets of odors with one set of five urinary odor transfer evaluation cloths for one household and sets the odor intensity at six levels based on the following evaluation criteria It evaluated and it carried out by the method of calculating the average point of 4 sets of odor intensity for every panelist. The higher the odor intensity score, the weaker the odor. Moreover, based on the average score (average score of six persons) of sensory evaluation, the deodorizing effect was evaluated by the following reference | standard.
(Evaluation of odor intensity)
5 points: no offensive odor at all.
4 points: It is felt to the extent that an offensive odor can finally be perceived.
3 points: The offensive odor is felt weak.
2 points: The offensive odor is felt a little strong.
1 point: Offensive odor is felt strongly.
0 point: An offensive odor is felt intensely.
(Evaluation criteria)
Good: The average score of sensory evaluation is 4.0 or more.
Δ: The average score of sensory evaluation is 3.0 to 3.9.
X: The average score of sensory evaluation is 2.9 or less.

Example 19
Furthermore, in the same manner as in Example 1, except that 1% by mass of an antibacterial agent (alkyl chloride (having 12 carbon atoms) trimethyl ammonium, manufactured by Lion Akzo, trade name "Arcard 12-37 W") was added, A liquid detergent composition was obtained. It was a / b = 2.5, b / c = 3333, a / c = 8333 and pH = 3.2.
As in Example 1, the urine odor removing effect and the oxygen gas absorption suppressing effect were evaluated, and both were いずれ. Furthermore, as described below, the antibacterial property was evaluated and was ◎.

Example 20
Furthermore, the procedure was carried out in the same manner as in Example 1 except that 0.1% by mass of an antibacterial agent (dichrosan (4,4'-dichloro-2-hydroxydiphenyl ether), trade name "TINOSAN HP 100", manufactured by BASF Corp.) was added. Thus, a liquid detergent composition for textiles was obtained. It was a / b = 2.5, b / c = 3333, a / c = 8333 and pH = 3.2.
As in Example 1, the urine odor removing effect and the oxygen gas absorption suppressing effect were evaluated, and both were いずれ. Furthermore, as described below, the antibacterial property was evaluated and was ◎.

<Evaluation of antibacterial activity>
(1) Sample used The test cloth after urine odor removal evaluation was used.
(2) Room drying conditions The test cloth after washing was arranged on a net for 8 hours in a room at 24 ° C. and a relative humidity of 95% RH to make room drying conditions.
(3) Sensory evaluation of urine odor It carried out similarly to urine odor removal performance evaluation. Each panelist smells 4 sets of smells with 4 sets of test cloths for 1 household as one set, and the odor intensity is evaluated in 6 levels based on the following evaluation criteria, and 4 pairs of odor intensity average for each paneler It was done by the method of calculating the point. The higher the odor intensity score, the weaker the odor.
Moreover, based on the average score (average score of six persons) of sensory evaluation, the following reference | standard evaluated the antimicrobial property.
(Evaluation of odor intensity)
5 points: no offensive odor at all.
4 points: It is felt to the extent that an offensive odor can finally be perceived.
3 points: The offensive odor is felt weak.
2 points: The offensive odor is felt a little strong.
1 point: Offensive odor is felt strongly.
0 point: An offensive odor is felt intensely.
(Evaluation criteria)
◎: The average score of sensory evaluation is 3.0 or more.
A: The average score of sensory evaluation is 2.5 to 2.9.
Δ: The average score of sensory evaluation is 2.0 to 2.4.
X: The average score of sensory evaluation is 1.9 or less.
