Hand dishwashing detergent composition

The present invention relates to a hand dishwashing detergent composition.

For hand dishwashing detergents, it is desirable to have sufficient foaming during cleaning and the persistence of foaming during cleaning. This foaming/bubble persistence is a very important physical property associated with the sustainability of cleaning, and the detergent has been mainly developed in the industry to have excellent foaming/bubble persistence.

Japanese Laid-Open Patent Publication No. SHO-62-215699 discloses a technique for cleaning a cleaning agent suitable for dishwashing, which contains a sulfosuccinate and has high foaming property and excellent cleaning power. Further, Japanese Laid-Open Patent Publication No. 2008-507611 discloses a technique of a dishwashing detergent composition containing a dialkyl sulfosuccinate and an amine oxide, and a detailed description thereof may contain a fatty acid as a builder. A foaming inhibitor which can use a fatty acid as a liquid lotion composition which can use an ethylene oxide condensate of a sulfosuccinic acid diester salt and a fatty alcohol as an anionic surfactant is described in Japanese Patent Laid-Open No. Hei 3-207799. A liquid or gel-like lotion composition which can use a dialkyl sulfosuccinate as an anionic surfactant is disclosed in JP-A-3-33197, and it is described that it may further contain betaine and/or oxidation. amine. A low-irritant cleaning composition containing a sulfosuccinic acid monoester salt and imparting an excellent moisturizing effect and conditioning effect to hair and skin is described in Japanese Patent Laid-Open Publication No. 2008-506727.

A hand dishwashing detergent composition containing a sulfosuccinic acid di- or monoalkyl ester or a salt thereof, an anionic surfactant, and a fatty acid or a salt thereof is disclosed in Japanese Laid-Open Patent Publication No. 2011-231310, the disclosure of which is incorporated herein .

The present invention relates to a hand dishwashing detergent composition comprising (a) an alkyl sulfosuccinate represented by the following formula (1) or a salt thereof (hereinafter referred to as (a) component], (b) An anionic surfactant having a hydrocarbon group of 8 to 21 carbon atoms and a sulfate group or a sulfonate group [excluding (a)] [hereinafter referred to as component (b)] 5 to 35 mass%, and (c a sulfobetaine type surfactant [hereinafter referred to as component (c)].

[Wherein, R ^1, R ² are a hydrogen atom or alkyl having of from 5 to 18, R ^1, R ² in at least one of an alkyl group having a carbon number of 5 to 18; i.e., R ¹ and R ² Except for the case of hydrogen atom at the same time; A ¹ and A ² are each independently an alkyl group having a carbon number of 2 to 4, and x and y are the average addition molar numbers, which are independently 0 to 6; M ¹ is a cation].

Further, the present invention relates to a method of cleaning a dishware which is hand-washed and cleaned by using a cleaning liquid of the hand dishwashing detergent composition of the present invention described above, and then rinsed with water.

In recent years, in order to reduce environmental load and effectively utilize water resources, it is preferable to reduce the amount of water used in hand washing and cleaning, and it is desirable to reduce the amount of washing water after cleaning with a dishwashing detergent as much as possible. However, a cleaning agent which is generally excellent in foaming/bubble persistence requires a large amount of water to complete the rinsing. Therefore, there is a strong demand for sufficient foaming and foam persistence when cleaning, but When washing, the bubble disappears instantly, and the hand-washing dishwashing detergent is rinsed with a small amount of water.

In this regard, in the case of the defoaming at the time of rinsing, no consideration is given in Japanese Patent Laid-Open No. Hei. No. 62-215699, Japanese Patent Laid-Open No. Hei. No. Hei. No. Hei. Further, in Japanese Patent Laid-Open No. Hei 3-207799, the fatty acid as an antifoaming agent exemplified as the "foaming inhibitor" is intended to be low-foaming at the time of cleaning, and it is not necessary to continuously form a sufficient amount of cleaning. The association between the bubble and the technique of instantaneous defoaming during rinsing. Further, in Japanese Patent Laid-Open No. Hei 3-33197, not only a specific example using an alkyl sulfosuccinate but also a carboxybetaine type surfactant as an example of a betaine, but a sulfobee is used. Specific examples of the alkali type surfactant are neither described nor suggested.

Accordingly, the present invention provides a hand dishwashing detergent which exhibits sufficient foaming and cleaning at the time of cleaning, but which disappears instantaneously upon rinsing, and which is rinsed with a small amount of water.

<foaming force (initial foaming amount) and defoaming property>

The dishwashing detergent composition of Table 1 was diluted to 3.2% by mass with 3.5°DH hard water, and was filled in the foam pump container described in Fig. 1 of Japanese Patent Laid-Open No. 2008-260852. Here, a screen having a screen size of 200/inch was installed in the bubble ejection mechanism. Then, 3 g of bubbles were prepared in a 500 ml measuring cylinder by continuously pressing the pump head of the upper portion of the container three times. Furthermore, the speed of full press is performed at a rate of 1 second per press. At this time, the capacity is recorded based on the scale of the cylinder, and the initial bubble amount is set. The foaming property was evaluated by the initial amount of foam.

Next, 100 ml of 3.5° DH hard water was added to the bubble through a hard water introduction mechanism (a homemade watering can) provided on the upper portion of the measuring cylinder, and left for 10 seconds. This operation was repeated until the total amount of hard water added became 300 ml. The last water was added and the amount of foam after 10 seconds of standing was measured. Furthermore, about The foaming property is determined by the rate of change of the amount of foam shown in the following formula during the addition of 300 ml of hard water.
