JP4932461B2 - Liquid detergent composition - Google Patents

Description

  The present invention relates to a liquid cleaning composition, a liquid cleaning composition suitable for cleaning hard surfaces such as tableware and cooking utensils, and hard surfaces around kitchens, and a cleaning method using the same.

  Liquid detergent compositions, particularly dishwashing detergents, are required to have high detergency and improved usability (inhibition of stickiness). Many dishwashing detergents use an anionic surfactant as a surfactant as a surfactant from the viewpoint of detergency, and in order to further improve the detergency against oil stains, an amine oxide surfactant Is often used as a foaming agent. This is because amine oxide has a cationic property in the middle and acidic regions, so it forms an ionic complex with the anion of the anionic surfactant, thereby improving the emulsifying power to oil, resulting in washing It seems that power improves.

  Further, from the viewpoint of reducing the environmental load, a concentrated liquid cleaning agent in which the concentration of the surfactant is increased and the amount of resin in the container is reduced is preferred and used. Such contact between the high concentration surfactant and the hard surface facilitates removal of oil stains adhering to the hard surface, while excessive surfactant causes the problem of sliminess.

  The sliminess becomes more prominent when an amine oxide type surfactant is used. The cause is that the amidoxide-type surfactant itself exhibits a property that it is easy to become slippery as compared with other surfactants, but it is presumed that the formation of the complex also has an influence. Reducing the amount of amine oxide surfactant improves the wetness during washing and rinsing, but the foaming properties are impaired, so both the foaming properties and the improvement in wetness during washing and rinsing are satisfied. There is a need for liquid detergents.

  The polyoxyalkylene type nonionic surfactant is a surfactant that is widely used in liquid detergents as in the case of the above-described anionic surfactants and amine oxide type surfactants. Are known.

  Patent Document 1 discloses a liquid detergent composition suitable for kitchen use, which contains an alkoxylate type compound having a 2-ethylhexyl group, an anionic surfactant, and an amine oxide type surfactant. It shows the effect of preventing the stickiness when washing and rinsing.

  Patent Document 2 discloses a thickening and foaming agent containing an ethoxylate type nonionic surfactant having a linear alkyl group having a specific chain length.

Patent Document 3 discloses that an effective detergent for washing hard surfaces such as dishwashing detergents can be obtained by combining two specific types of higher fatty acid alcohol alkylene oxide addition surfactants. Yes.
