Description

  The present invention relates to a liquid detergent composition.

  As a cleaning composition, a granular cleaning composition and a liquid cleaning composition are mainly mentioned. The liquid detergent composition is superior to the granular detergent composition in that it can be applied directly to the soiled part and there is no dusting. However, the liquid detergent composition achieves both cleaning power and liquid stability. Is an important technical issue. First, a calcium scavenger such as zeolite, which is generally blended for the purpose of improving detergency in a granular detergent composition, is difficult to blend in a sufficient amount in terms of liquid stability. Alkyl ether sulfates and nonionic surfactants that are excellent in hard water resistance are mainly used.

  In recent years, awareness of the environment has increased, and there has been a strong demand for the appearance of a detergent composition that has less impact on the environment. The so-called concentrated type cleaning composition, which has a higher concentration of cleaning components than the conventional cleaning composition, reduces the size of the cleaning composition itself, reduces the amount of resin in the container, reduces transportation costs, and reduces waste after use. It is considered to be very effective in reducing the environmental load such as reduction.

  However, in a normal liquid cleaning composition, when the concentration of the surfactant as a cleaning component is increased, there is a problem that viscosity increase or gelation occurs and the usability is remarkably impaired. This is because an increase in the concentration of the surfactant forms a remarkably high phase such as liquid crystal or crystal in the composition. In addition, in such a high-concentration surfactant system, a method for obtaining a low-viscosity composition by adding a large amount of a solvent, a solubilizing agent, or the like is generally known, but the composition is water when diluted with water, particularly cold water. When diluted, the diluted composition forms a liquid crystal, causing poor solubility, and when the surfactant concentration is increased, the composition is likely to solidify during low-temperature storage. There was a problem with sex.

  Patent Documents 1 to 3 describe concentrated liquid detergent compositions containing specific nonionic surfactants, but have problems in stability at low temperatures and solubility in cold water.

  It is known that bleaching power is improved by adding hydrogen peroxide to a liquid detergent composition. For example, Patent Document 4 discloses a composition containing hydrogen peroxide having an increased surfactant content. However, the surfactant content is 28% by mass or less, and the nonionic surfactant is 18% by mass. % Or less. In addition, Patent Documents 5 to 7 describe a concentrated type liquid detergent composition that is excellent in hydrogen peroxide stability and highly blended with a surfactant. There was a problem.
