Description

Dishwashing composition for hand washing

The present invention relates to a dishwashing composition for hand washing.
Background art

¡Dishwashing agents for hand washing are required to have abundant foaming during washing and persistence of foam during washing. This foamability / foam persistence is a very important physical property that has a correlation with the persistence of washing, and until now, the development of a detergent having excellent foamability / foam persistence has been mainly performed.

JP-A-62-215699 discloses a technique of a detergent suitable for dishwashing containing sulfosuccinate, having high foamability and excellent detergency. JP 2008-507611 discloses a technique of a dishwashing composition containing a dialkyl sulfosuccinate and an amine oxide, and it is described in detail that a fatty acid can be contained as a builder. JP-A-3-207799 describes that a fatty acid can be used as a foam inhibitor in a liquid detergent composition that can use a sulfosuccinic acid diester salt and an ethylene oxide condensate of a fatty alcohol as an anionic surfactant. JP-A-3-33197 discloses a liquid or gel detergent composition that can use a dialkyl ester sulfosuccinate as an anionic surfactant, and further describes that it can contain betaine and / or an amine oxide. ing. JP 2008-506727 describes a hypoallergenic cleansing composition that contains a sulfosuccinic acid monoester salt and provides an excellent moisturizing and conditioning effect on the hair and skin.

Japanese Patent Application Laid-Open No. 2011-231310 distributed on November 17, 2011 discloses a dishwashing detergent composition for hand washing containing a sulfosuccinic acid di- or monoalkyl ester or a salt thereof, an anionic surfactant and a fatty acid or a salt thereof. Yes.

SUMMARY OF THE INVENTION The present invention provides (a) a sulfosuccinic acid alkyl ester represented by the following general formula (1) or a salt thereof (hereinafter referred to as (a) component), (b) a hydrocarbon group having 8 to 21 carbon atoms, An anionic surfactant having a sulfate ester base or a sulfonate group (excluding (a)) [hereinafter referred to as component (b)] 5 to 35% by mass, and (c) a sulfobetaine type surfactant [ Hereinafter, it is related to the dishwashing composition for hand-washing containing (c) component].

[Wherein, R ¹ and R ² are each an alkyl group having 5 to 18 carbon atoms or a hydrogen atom, and at least one of R ¹ and R ² is an alkyl group having 5 to 18 carbon atoms. That is, the case where R ¹ and R ² are hydrogen atoms at the same time is excluded. A ¹ and A ² are each independently an alkylene group having 2 to 4 carbon atoms, and x and y are average added mole numbers, and are each independently 0 to 6. M ¹ is a cation. ]

The present invention also relates to a tableware cleaning method in which tableware is washed by hand with a cleaning liquid using the dishwashing composition for handwashing of the present invention, and then rinsed with water.

DETAILED DESCRIPTION OF THE INVENTION In recent years, it has been preferable to reduce the amount of water used for hand washing and washing, and it is desirable to reduce the rinse water after washing with a dishwashing agent as much as possible for the purpose of reducing environmental impact and effectively using water resources. . However, detergents that are generally excellent in foamability / foam persistence require a large amount of water to complete rinsing. Accordingly, there is a strong demand for a dishwashing detergent for hand washing that exhibits abundant foaming and foam persistence during washing, but disappears instantly during rinsing and is rinsed with a small amount of water.

In this respect, Japanese Patent Application Laid-Open No. Sho 62-215699, Japanese Translation of PCT International Publication No. 2008-507611, Japanese Patent Application Laid-Open No. Hei 3-207799, and Japanese Patent Application Laid-Open No. 2008-506727 do not consider any bubble disappearance at the time of rinsing. Further, the fatty acid as an antifoaming agent, which is listed as “Foaming Inhibitor” in JP-A-3-207799, is intended to make it low in foaming properties during cleaning. There is no suggestion of a relationship between the continuous formation of water and the technology of instant defoaming during rinsing. Furthermore, in JP-A-3-33197, there is no specific example using a sulfosuccinic acid alkyl ester, and there is an example using a carbobetaine type surfactant as a betaine, but a sulfobetaine type surfactant is used. No specific examples were given or suggested.

Accordingly, the present invention provides a dishwashing agent for hand washing that exhibits abundant foaming at the time of washing and the persistence of the foam at the time of washing, but the foam disappears instantaneously at the time of rinsing and the rinsing with a small amount of water is completed.

These are the schematic diagrams which show the foam extinction evaluation method performed in the Example. These are the schematic diagrams which show the piercing | piercing state of the introduction means (joro) of the hard water used by the foam extinction evaluation of the Example.

<Foaming power (initial foam amount) and foam disappearance>
The dishwashing composition of Table 1 was diluted to 3.5% by mass with 3.5 ° DH hard water and filled into a pump former container described in FIG. 1 of JP-A-2008-260852. Here, a single mesh having a mesh size of 200 / inch was attached to the foam discharge mechanism. Next, 3 g of foam was produced in a 500 ml graduated cylinder by continuously pushing out the pump head at the top of the container for 3 pushes. Note that the speed of pushing out was 1 second per push. At this time, the volume was recorded from the scale of the graduated cylinder and used as the initial amount of foam. Foaming property was evaluated by this initial foam amount.

Next, 100 ml of 3.5 ° DH hard water was added to the foam through a means for introducing hard water (manufactured by hand) installed at the top of the graduated cylinder and left for 10 seconds. This operation was repeated until the total amount of hard water added reached 300 ml. The final amount of water was added and the amount of foam after standing for 10 seconds was measured. In addition, about 300-ml hard water addition, it calculated | required from the foam amount change rate shown by following Formula, and if it became 70% or more by 300 ml addition, it was judged that rapid foam disappearance by dilution (rinsing) could be achieved. .

Next, as shown in FIG. 2, a polyethylene perforated plate having 13 holes with a diameter of 2 mm at 9 mm intervals was prepared for a thin circular polyethylene plate with a diameter of 4 cm. Finally, the polyethylene perforated plate was fixed as the opening 4 to the lid opening (diameter 4 cm) at the top of the excised wide-mouth bottle to produce hard water introducing means 3 (handmade watering device). The hard water introducing means 3 (manufactured by hand) thus produced was fitted into the opening of the graduated cylinder 1 while being kept in an inverted state as shown in FIG. Hard water was introduced from the excised side of the wide-mouth bottle.
