MODE FOR CARRYING OUT THE INVENTION <Liquid detergent composition for hard surface>
The liquid detergent composition for hard surface of the present invention defines the content of an anionic surfactant having a hydrocarbon group having 8 to 21 carbon atoms and a sulfate ester group or a sulfonic acid group as the component (b). Thus, the interaction between the component (a) having two highly hydrophobic hydrocarbon groups and the highly hydrophilic sulfate group and the component (c) which is an amphoteric surfactant can be strengthened. Thereby, the surfactant contained in the liquid detergent composition for hard surface of the present invention can easily penetrate into the oil stain containing solid fat, and the solid fat can be easily peeled off from the hard surface. It is presumed that the effect of improving the cleaning power was obtained.
And when using the liquid detergent composition for hard surfaces of the present invention in a method of directly contacting the hard surface, the concentration of the surfactant applied to the hard surface is determined by using a sponge containing water. It becomes higher than the case where it contacts. For this reason, the effect of the surfactant of the present invention is more prominent.
From these, by using the liquid detergent composition for hard surface of the present invention, oil stains containing solid fat adhering to a hard surface such as plastic are not rubbed with a flexible material such as sponge. In other words, excellent cleaning power can be obtained even by a cleaning method in which no mechanical force is applied.
