Description

The present invention relates to a concentrated liquid cleaning composition.

2. Description of the Related Art Conventionally, tableware detergents used for washing tableware, kitchen utensils, vegetables, fruits and the like are mainly in liquid form. Furthermore, there is a demand for a concentrated liquid detergent composition that uses a high-concentration detergent diluted with water from the viewpoint of environmental load, mainly for commercial dishwashing detergents.

As described above, for example, Patent Document 1 includes two specific nonionic surfactants and stearic acid as a detergent composition that has a higher component concentration than conventional detergents and is diluted upon use. A cleaning composition is disclosed.

JP 2004-035576 A

However, in the concentrated liquid detergent composition described in Patent Document 1, when diluted with water, the viscosity rapidly decreases and easily flows out of a sponge or the like. For this reason, users tend to use a detergent composition in excess of the specified amount in order to ensure adequate detergency, which increases the cost of washing, causes drainage troubles, water pollution, etc. There was.

Therefore, it is desirable that such a concentrated liquid detergent composition has a viscosity suitable for use after dilution. In consideration of workability during production, it is desirable that the viscosity of the concentrated liquid cleaning composition itself is not too high.
Furthermore, the liquid detergent composition is desired to have a transparent appearance that does not cause separation or cloudiness.

The present invention has been made to solve the above problems, and is a liquid detergent composition having good workability at the time of production, and having a moderate viscosity and a transparent appearance before and after dilution. An object is to provide a cleaning composition.

In order to achieve the above object, the liquid detergent composition of the present invention is a concentrated liquid detergent composition comprising (A) 0.5 to 5% by weight of a compound represented by the general formula (1) And (B) an anionic surfactant 10 to 40% by weight, and (C) at least one selected from the group consisting of an amphoteric surfactant and a nonionic surfactant in a total amount of 0.5 to 10% by weight. (D) 0.1-15 weight% of solubilizer is contained as an essential component, It is characterized by the above-mentioned.

In the formula, R is an alkyl group or alkenyl group having 6 to 18 carbon atoms, and A ¹ O and A ² O are the same or different and each represents an oxyalkylene group having a linear or branched chain having 2 to 4 carbon atoms. Yes, m and n are the average number of moles of alkylene oxide added, and are independently a number from 0 to 5, and m + n is a number from 1 to 5.

The liquid detergent composition of the present invention contains 0.5 to 5% by weight of component (A). When the content of the component (A) is less than 0.5% by weight, the viscosity becomes too low at the time of dilution or the foaming property is lowered. On the other hand, if it exceeds 5% by weight, the liquid detergent composition becomes turbid and impairs the appearance.
In addition, unless otherwise indicated, the density | concentration (weight%) of each component in this specification is defined as the density | concentration in the pure part of each component in a liquid cleaning composition.

When the content of the component (B) is less than 10% by weight, the detergency and foamability are deteriorated. On the other hand, if it exceeds 40% by weight, the liquid detergent composition becomes cloudy and the appearance is impaired.

The liquid cleaning composition of the present invention contains 0.5 to 10% by weight of the component (C). When the content of the component (C) is less than 0.5% by weight, the viscosity at the time of dilution becomes too low. On the other hand, if it exceeds 10% by weight, the liquid detergent composition becomes turbid and the appearance is impaired.

The liquid detergent composition of the present invention contains 0.1 to 15% by weight of component (D). When the content of the component (D) is less than 0.1% by weight, the other components are not sufficiently dissolved, so that the liquid detergent composition becomes turbid and the appearance is impaired. Furthermore, since other components are not sufficiently dissolved, the viscosity at the time of dilution is reduced, and the foaming property is reduced. Moreover, even if it exceeds 15% by weight, the ability to dissolve other components does not improve, so excessive addition is not preferable from the viewpoint of production cost.

By satisfying the above conditions, the liquid detergent composition of the present invention is a concentrated liquid detergent composition having good workability during production and having an appropriate viscosity and transparent appearance before and after dilution. . Therefore, the components are separated during storage and the performance is not deteriorated, and the appearance is not impaired due to white turbidity, etc., and it is difficult for the cleaning agent to flow off from the sponge, etc., and the concentration of the cleaning agent contained in the sponge is increased. Can keep.

This operation was repeated, and the detergency was evaluated by counting the number of dishes until the dirt adhering to the test dish could not be wiped off with a sponge. The results are shown in Tables 1 and 2.
In addition, the case where the number of the dishes on which the dirt was wiped off was 3 or more was evaluated as ○, and the case where it was 2 or less was evaluated as ×.

From the results of Table 1 and Table 2, it was found that the cleaning compositions according to Examples 1 to 7 had good appearance and cleaning power and exhibited a good viscosity before and after dilution.
On the other hand, the detergent composition according to Comparative Example 1 in which the component (A) is excessive, the stock solution and the 3-fold diluted solution become cloudy, and the detergent composition according to Comparative Example 2 lacking the component (A). The product was insufficient in the viscosity of the 3-fold diluted solution.
Moreover, the cleaning composition which concerns on the comparative example 3 whose sum total of the average addition mole number of the oxyalkylene group of (A) component exceeds 5 was insufficient in the viscosity of 3 times dilution liquid.
On the other hand, the detergent composition according to Comparative Example 4 in which the component (B) is excessive has a cloudy stock solution, and the detergent composition according to Comparative Example 5 in which the component (B) is insufficient has a detergency and a starting force. Foam was low.
Furthermore, the detergent composition according to Comparative Example 6 in which the component (C) is excessive is that the stock solution becomes turbid, further has low foaming properties, and the detergent composition according to Comparative Example 7 that lacks the component (C). Had low detergency and foaming properties.
From the above, it was found that the cleaning composition according to the present invention has sufficient cleaning power and foaming power, and has an appropriate viscosity before and after dilution.
