Description

Liquid cleaning agent

The present invention relates to a liquid cleaning agent.
The present application is filed on October 19, 2015, Japanese Patent Application No. 2015-205465 filed in Japan, October 19, 2015, Japanese Patent Application No. 2015-205466 filed in Japan, October 19, 2015 The priority is claimed based on Japanese Patent Application No. 2015-205467 filed in Japan and Japanese Patent Application No. 2015-256627 filed in Japan on December 28, 2015, the contents of which are incorporated herein by reference.

As a method of cleaning tableware, etc., which are kitchen utensils, a liquid cleaning agent is taken in a cleaning tool such as a sponge and the cleaning object is rubbed (non-immersion method) or a liquid cleaning agent is used. There is a case where a method (immersion method) is performed in which a cleaning liquid is dispersed in water and washed with a cleaning tool such as a sponge while the object to be cleaned is immersed in the cleaning liquid.
Therefore, the liquid cleaning agent is required to have sufficient cleaning power in both the non-immersion method and the immersion method.

For example, even if it is a liquid detergent which can obtain a good detergency in the non-immersion method, the dispersibility when diluted in water is not sufficient (that is, the dilution dispersibility is inferior). It may not be obtained. That is, in the dipping method, a liquid cleaning agent is put in a container containing water to prepare a cleaning liquid in which the cleaning agent is diluted, and the cleaning liquid is soaked in a cleaning tool such as a sponge to wash dishes and the like. At this time, if the dispersibility of the liquid cleaning agent in water is not sufficient, the cleaning agent remains undissolved at the bottom of the container and the like, and the dishes are cleaned with a cleaning liquid having a low concentration of the cleaning agent. Thereby, in the immersion method, sufficient cleaning power for tableware and the like cannot be obtained. Therefore, there is a demand for a detergent having high viscosity and high water dispersibility.
Furthermore, from the viewpoint of hygiene, there is a demand for a detergent having a high sterilizing activity for cleaning tools such as sponges.
Patent Document 1 discloses a liquid detergent composition containing a surfactant in a range of 30 to 50% by weight, wherein at least 50% by weight or more of the surfactant is a nonionic surfactant, and A liquid detergent composition having excellent detergency for tableware and the like, wherein at least 35% by weight or more of the nonionic surfactant is a specific alkanolamide, is disclosed.
However, Patent Document 1 does not consider dispersibility when the liquid detergent composition is diluted in water.

In addition, as a liquid detergent for tableware or the like, a liquid detergent having a high viscosity (for example, 1000 mPa · s or more) may be preferred.
This is because the high viscosity makes the image of the high cleaning power of the liquid detergent.
Liquid detergents with increased viscosity include at least one hydrotropic surfactant, at least one alkylbetaine or sultain, a certain amount of electrolyte, water, and other surfactants or additives. A viscous liquid cleaning composition having a specific viscosity has been proposed (for example, Patent Document 2).
However, Patent Document 2 does not consider water dispersibility and disinfecting activity.

Japanese Patent Laid-Open No. 11-80785 Special table 2013-508511 gazette

By the way, the liquid detergent is often colored with a pigment.
The liquid cleaning agent is colored so that it has a high detergency and sterilization ability, and the commercial value is improved.
In addition, when the cleaning object is cleaned by the dipping method, if the liquid cleaning agent is colored, the user can easily adjust the amount of the liquid cleaning agent in the cleaning agent based on the color tone of the cleaning liquid.
However, the high-viscosity and colored liquid cleaning agent is stored in a container (for example, tarai, sink, etc.), an object to be cleaned, a cleaning tool, etc. (hereinafter sometimes collectively referred to as an object to be cleaned). It becomes easy to stay.
For this reason, the cleaning object or the like is easily colored by the pigment in the liquid cleaning agent.
This invention is made | formed in view of the said situation, and the 1st aspect of this invention aims at the liquid cleaning agent which is excellent in detergency and excellent in dilution dispersibility.
The second aspect of the present invention is directed to a liquid detergent having excellent detergency and dilution dispersibility and having an increased viscosity.
The third aspect of the present invention is directed to a liquid cleaning agent in which an object to be cleaned or the like is hardly colored even when the viscosity is increased.
The fourth aspect of the present invention is directed to a liquid detergent that is highly viscous but excellent in water dispersibility, and also excellent in detergency and disinfecting activity.
