Description

  The present invention relates to a liquid cleaning composition for hard surfaces.

  There is a strong demand for hand-washing dishwashing detergents that have a detergency against oil stains. In particular, in a tableware having a hydrophobic surface such as a plastic tapper or a lunch box, oily dirt containing a large amount of solid fat such as beef tallow and lard is difficult to remove, and high detergency is required. For this reason, a cleaning method that uses hot water of about 40 ° C. to 45 ° C. or is devised such as washing twice is usually used.

  Patent Document 1 discloses an anionic surfactant having (a) a di- or monoalkyl sulfosuccinate or a salt thereof, and (b) a hydrocarbon group having 8 to 21 carbon atoms and a sulfate ester group or a sulfonate group [ However, (a) is excluded), and (c) a dishwashing composition for hand-washing containing an alkyl glyceryl ether (the alkyl group has 6 to 18 carbon atoms) has a rich lather and instantly eliminates nulliness when rinsing. It is stated that rinsing with a small amount of water is complete.

<Liquid cleaning composition for hard surfaces>
The liquid detergent composition for hard surfaces of the present invention specifies the content of the (b) anionic surfactant having a hydrocarbon group having 8 to 21 carbon atoms and a sulfate ester group or a sulfonic acid group. Thereby, the interaction between the component (a) having a dialkyl group having high hydrophobicity and the sulfate group having high hydrophilicity and the component (c) which is an alkyl glyceryl ether can be strengthened. This makes it easier for the surfactant contained in the hard surface liquid cleaning composition of the present invention to penetrate into oil stains containing solid fat, and facilitates the separation of the solid fat from the oil stain, thereby resulting in cleaning. It is estimated that the effect of improving the power was obtained.

<How to clean hard surface>
The method for cleaning a hard surface of the present invention is a method for cleaning a hard surface, wherein the hard surface liquid cleaning composition of the present invention is brought into contact with the hard surface.
That is, in the method for cleaning a hard surface of the present invention, the liquid cleaning composition for a hard surface of the present invention is used. Preferred embodiments of the composition are the same as the above-described liquid cleaning composition for hard surfaces of the present invention.
The method for cleaning a hard surface of the present invention comprises the step of bringing the liquid cleaning composition for a hard surface of the present invention into contact with a hard surface to which an oil stain is attached, and a hard surface to which an oil stain containing solid fat is further attached. It can be suitably implemented as a washing method for
The oil stain containing solid fat is a stain containing oil and fat, and this fat and oil presents a solid at normal temperature (20 ° C.). The oil stain containing solid fat is typically an oil stain containing solid fat, and further an oil stain containing solid fat and liquid oil. The form of the oil stain containing solid fat when the hard surface liquid detergent composition is brought into contact may be a state in which solid fat and liquid oil are mixed.

In the method for cleaning a hard surface of the present invention, the liquid cleaning composition for a hard surface is brought into contact with the hard surface.
Specifically, the hard surface liquid cleaning composition is in contact with a hard surface in a stock solution, or the hard surface liquid cleaning composition is in a stock solution, and is contacted with a hard surface without dilution. That is, there is a cleaning method in which the hard surface liquid detergent composition is brought into contact with the hard surface without being diluted. Furthermore, there is a cleaning method in which the hard surface liquid cleaning composition is brought into contact with a hard surface to which oily dirt containing solid fat has adhered without being diluted.
To bring the liquid cleaning composition for hard surfaces into contact with the hard surface without diluting means that the cleaning composition is intentionally diluted with water or the like and then not brought into contact with the hard surface. For example, in the case where water droplets or the like are brought into contact with a hard surface to which water droplets or the like have adhered, or when water droplets adhere to the hard surface after the hard surface liquid cleaning composition is brought into contact with the hard surface, the liquid cleaning for the hard surface is performed. It can be understood that the agent composition is brought into contact with the hard surface without dilution.
In the present invention, it is preferable that the undiluted solution of the liquid cleaning composition for hard surfaces is adhered to the hard surface as it is, that is, without changing the composition.
