Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a liquid cleanser composition that has low frictional resistance and can be cleaned with light force when polishing hard surfaces. [Prior Art] Many liquid cleanser compositions have been proposed in the past. For example, regarding storage stability, JP-A-57-
Publication No. 16098, Japanese Patent Publication No. 57-100198, Japanese Patent Publication No. 1983-100198
Publication No. 55-5947, Japanese Patent Application Laid-Open No. 51-1973 for cleaning power
No. 50909, JP-A-52-133306, and JP-A-59 regarding the damage resistance of the polished surface and the particle size of the abrasive.
Many techniques are known, such as the publication No.-84999.
However, no study has been conducted on the relationship between the force applied to the cleaning surface and the composition. [Problem to be solved by the invention] When cleaning metal surfaces such as stainless steel with a cleanser, it is desirable to be able to easily remove dirt with less force, but with conventional cleansers, it is not possible to clean sufficiently without applying much force. You can't expect power. Also, if too much force is applied, the metal surface is likely to be damaged. [Means for solving the problem] During cleaning operations, frictional resistance acts even on areas that are not contaminated, resulting in wasted force and causing damage. Therefore, by lowering the frictional resistance in areas that are not contaminated so that force is transmitted more efficiently to areas that have dirt, dirt can be removed more efficiently with a lighter force. As a result of intensive research, the present inventors have discovered that the object of the present invention can be achieved in a specific compounding system, and have completed the present invention. That is, the present invention provides (a) a higher fatty acid alkanolamide or its alkylene oxide adduct (b) an alkali metal salt of alkylbenzenesulfonic acid in a ratio of 2.0≧(a)/(b)≧1.2, (a)+(b) ) = 4 to 8% by weight, further (c) water-insoluble abrasive 10 to 70% by weight (d) higher fatty acid or its alkali metal salt 0.03 to

[Example] The present invention will be described below with reference to Examples, but the present invention is not limited to these Examples. The compositions shown in Table 1 were prepared, and the frictional resistance, detergency, and scratch resistance of each composition were evaluated as follows. <Frictional Resistance> 1 g of the sample was evenly applied to a sponge (3 x 7 cm) moistened with water and lightly wrung out. The lateral tensile force (g) required to move the above sponge was measured on a stainless steel plate under a load of 1 kg. The tensile force when the composition was set to 1 was defined as the frictional resistance. <Cleaning power> A thin layer of rapeseed oil/carbon black = 9/1 was applied onto an iron plate and treated at 180°C for 40 minutes. 1 g of the sample was applied to a lightly wrung sponge (3 x 7 cm) moistened with water, and the iron plate was washed 50 times under a load of 1 kg. Cleaning rate (%) 91-100...5 66-90...4 36-65...3 11-35...2 0-10...1 <Scratchability> Collect 1 g of sample and clean it with a urethane sponge. After washing the stainless steel surfaces of bathtubs and sinks 50 times, we visually observed and evaluated the presence of scratches. ○……Does not hurt○△……Normally there is no problem, but if you rub it too hard it will hurt a little △……It will hurt a little ×……It will hurt
