Description

  The present invention relates to a liquid detergent composition, and more particularly to a liquid detergent composition suitable for hard surfaces having excellent detergency against oil stains.

In general, cleaning agents having a composition suitable for each of them are used in order to remove different stains to be treated, such as bathrooms, kitchens, and floors. For example, kitchen cleaners used around kitchens such as ovens, ovens, walls and floors around the range, and exhaust fans are used to remove oil stains that have been altered by the action of heat, sunlight, oxygen in the air, etc. A cleaning agent containing an activator, a solvent, an alkali agent and the like is used. Also, as bathroom cleaners used in bathrooms such as bathtubs, bathroom walls and floors, metal soaps, especially detergents containing detergents, metal ion sequestering agents, etc., are used to remove dirt from fatty acid calcium salts. The agent is used. Such detergents are often adjusted to be alkaline with a pH of 10 or higher in order to exhibit high cleaning performance.
Conventionally, a technique for containing a water-soluble polymer compound in a cleaning agent is known. For example, Patent Document 1 discloses a specific water-soluble property in a cleaning agent containing a surfactant, a solvent, an alkali agent, and a pigment. It is described that, by blending an organic polymer, the pigment dispersibility in the composition can be enhanced and the storage stability can be improved.

  Although higher detergency than before is still required, it is not desirable from the viewpoint of environment and safety to increase the concentration of the alkali agent or surfactant in order to achieve high detergency. Therefore, if the hard surface to be cleaned is surface-modified with a cleaning agent so that the dirt itself is difficult to adhere or the attached dirt can be easily removed, the concentration of alkali agent or surfactant is more than necessary. Therefore, easy cleaning can be realized without substantially increasing the cleaning power, and the cleaning power is substantially increased.

  Then, this invention makes it a subject to provide the alkaline liquid detergent composition which can exhibit high detergency with respect to various stain | pollution | contamination, especially modified | denatured oil stain | pollution | contamination.
