Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a sponge, a cutting board,
The present invention relates to a detergent composition suitable for sterilizing and cleaning kitchen utensils such as cloths, dishes such as dishes, and foods such as vegetables and fruits.

[0002]

2. Description of the Related Art Generally, kitchen utensils such as sponges, cutting boards and cloths, and dishes such as dishes are contaminated by harmful microorganisms derived from raw ingredients. For this reason, household disinfection, hot water disinfection, dry disinfection, sunlight disinfection, and the like are performed. In addition, foods such as vegetables and fruits are easily contaminated by harmful microorganisms, and runoff is generally removed at home by washing with a neutral detergent for kitchen use.

[0003] However, it is complicated to sterilize tableware by the above-mentioned means, and the quality of foods, such as flavor, is reduced. Can not. Furthermore, the removal of bacteria by a neutral detergent is a physical method, so that the removal of bacteria may be incomplete.

[0004] Therefore, a cleaning agent having both a cleaning effect and an excellent sterilizing effect is desired. As such a detergent, a germicidal detergent composition in which polylysine is combined with a chelating agent is disclosed in JP-A-9-176689. However, this detergent has the disadvantage that the stability of polylysine during high-temperature storage is low, and the bactericidal activity is reduced by long-term storage, leaving room for improvement.

[0005]

The present invention relates to (a) 1-80% by weight of a surfactant, (b) 0.0001-1% by weight of polylysine and (c) 2-bromo-2-nitropropane-1,3. -Diol, 1,
An object of the present invention is to provide a detergent composition containing 0.00001 to 0.2% by weight of one or more compounds selected from 2-benzisothiazolin-3-one and 5-chloro-2-methyl-4-isothiazolin-3-one. .

Evaluation criteria are as follows: foam height of 80 mm or more: ○, 70 mm to less than 80 mm, △: less than 70 mm ×
And

(2) Detergency test A 10% aqueous solution (detergent A) of sodium dodecylbenzenesulfonate (soft type) was added to 10 subjects, as shown in Tables 1 and 2.
Using a 15% aqueous solution of the composition (detergent B), apply 1 g of each detergent to a sponge (containing 20 g of water in advance) to actually perform the cleaning operation, and compare the detergent with the detergent A. The soil cleaning power of B was evaluated. The object to be cleaned is a model liquid of tallow / salad hot water (weight ratio: 9/1) completely dissolved at 60 ° C to make a uniform liquid, 2 g of which is evenly applied to the center of a white magnetic dish (20 cm in diameter) Five pieces were air-dried all day and night. The subjects were rated according to the following ratings. The average score of the 10 subjects was 4.5 or more, ◎; 3.5 or more, but less than 4.5; ○, 2.5 or more, but less than 3.5; Detergent B is good 5 points Detergent B is slightly good 4 points Both are the same 3 points Detergent A is slightly good 2 points Detergent A is good 1 point.

(3) Bactericidal power test The bactericidal power test is based on the floating test method (quantitative test method) described on p. I went according to. Specifically, 50 μl of 10 ⁸ to 10 ¹⁰ bacterial suspensions were added to 2 ml of a 10% aqueous solution of the composition shown in the table, mixed well, and allowed to stand for 3 hours. Subsequently, 0.1 m of the detergent solution was collected, added to 1.5 ml of SCDLP medium, mixed well, and cultured at 30 ° C. for 48 hours. The turbidity of the medium was visually observed to determine the growth of the bacteria. Two kinds of bacteria, Escherichia coli and Staphylococcus aureus, were used. If no growth was observed, it was evaluated as ○, if it was slightly growing, △, and if it was clearly growing, ×. In this test, the initial sterilizing power and the high-temperature sterilizing power were measured by the following methods.

1. Initial bactericidal activity After the composition was prepared, it was stored at 5 ° C. in a 100 ml brown glass bottle with a lid, and the bactericidal activity was measured within one week by the above method. 2. After preparing the composition, it is placed in a 100 ml brown glass bottle with a lid.
The solution was stored at 50 ° C., and the bactericidal activity after one month was measured by the above method. This condition corresponds to a case where the storage is performed for about one year in a normal warehouse.
