[0005] When a composition is foamed and used, a step of removing the foam by rinsing is performed after use. In recent years, there has been a strong demand for water conservation from the viewpoint of reducing environmental impact. However, for example, foam generated from a composition containing a surfactant has been difficult to remove from an object without using a large amount of water. For this reason, there is a strong demand for a foam control technology that does not interfere with abundant foaming during use and that eliminates foam with only a small amount of water during rinsing. In view of the above circumstances, the present invention provides a novel foam control agent composition for a foaming composition, which maintains the foaming of the foaming composition when used in a foaming composition and has excellent defoaming properties when rinsing the composition. [Means for solving the problem]

[0006] The present invention relates to a foam control agent composition for a foamable composition, which comprises (a) an alkyl sulfosuccinate ester having a branched alkyl group having from 8 to 11 carbon atoms (hereinafter referred to as component (a)), and (b) a quaternary ammonium salt surfactant (hereinafter referred to as component (b)).

[0007] The present invention also relates to a foamable composition containing (a) a sulfosuccinate alkyl ester having a branched alkyl group having from 8 to 11 carbon atoms (hereinafter referred to as component (a)), (b) a quaternary ammonium salt surfactant (hereinafter referred to as component (b)), (c) a surfactant (excluding components (a) and (b), hereinafter referred to as component (c)), and water.

[0008] The present invention also relates to a liquid cleaning composition for hard surfaces, which contains (a) a sulfosuccinate alkyl ester having a branched alkyl group having from 8 to 11 carbon atoms (hereinafter referred to as component (a)), (b) a quaternary ammonium salt surfactant (hereinafter referred to as component (b)), (c) a surfactant (excluding components (a) and (b), hereinafter referred to as component (c)), and water. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a foam control agent composition for a foamable composition, which maintains the foaming properties of the foaming composition during use and has excellent defoaming properties when rinsing the composition. That is, according to the present invention, by maintaining the foamability of a foamable composition during use, it is possible to provide a foam control agent composition for a foamable composition that has excellent defoaming properties when rinsing the composition while maintaining the effects of the composition (e.g., detergency). In the following description, unless otherwise specified, defoaming properties means defoaming properties (foam disappearance properties) when rinsing. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] The mechanism by which the foam control agent composition for a foaming composition of the present invention improves defoaming properties during rinsing is not clear, but is presumed to be as follows. When the composition is diluted with rinse water, a complex of components (a) and (b) precipitates. It is speculated that the bulky and hydrophobic structure of component (a) destabilizes the foam when oriented in the foam film, improving defoaming properties. It is also possible that component (a) is unable to orient quickly upon dilution due to its slow orientation into the foam film, destabilizing the foam. However, the foam control agent composition for foamable compositions of the present invention is not limited to this mechanism of action.

[0066] <Evaluation method for antifoaming properties> For the evaluation of defoaming properties, a container of a commercially available spray-type bathroom cleaner (Kao Corporation, Bath Magiclean) was cleaned and used. The container was filled with the liquid hard surface cleaner composition shown in the table. 5 g of foam was generated in a 500 ml measuring cylinder by pulling the trigger of the container five times. The pulling speed was 1 second per pull. The volume was recorded from the graduations on the measuring cylinder. This was taken as the initial foam volume. Next, 50 ml of ion-exchanged water was added to the foam through the ion-exchanged water introduction means (handmade watering can) installed at the upper part of the graduated cylinder, and the operation of adding 50 ml of ion-exchanged water every 1 minute was carried out 4 times in total (the addition of 50 ml of ion-exchanged water was carried out 4 times in total, and the total addition amount was 200 ml). For each operation of adding 50 ml of ion-exchanged water, the foam volume 30 seconds after the total addition of ion-exchanged water was measured. This was taken as the foam volume after the addition of ion-exchanged water. The state when adding ion-exchanged water to the graduated cylinder is shown in Fig. 1. In Fig. 1, 1 is the graduated cylinder, 2 is the foam, 3 is the ion-exchanged water introduction means (handmade watering can), 4 is the opening of the introduction means, and Fig. 2 is a schematic diagram showing the perforated state of the opening 4 of the ion-exchanged water introduction means 3. The manufacturing method of the handmade watering can, which is the ion-exchanged water introduction means, is as follows. First, the main body part from the bottom to about one-third of the height of a 250-ml polypropylene wide-mouth bottle (manufactured by AS ONE: I-Boy wide-mouth bottle) was cut off. Next, a polyethylene perforated plate with 13 holes with a diameter of 2 mm at an interval of 9 mm was prepared for a thin circular polyethylene plate with a diameter of 4 cm as shown in Fig. 2. Finally, the above-mentioned polyethylene perforated plate was fixed as the opening 4 to the cap opening (diameter 4 cm) at the upper part of the cut-off wide-mouth bottle to manufacture the ion-exchanged water introduction means 3 (handmade watering can). The ion-exchanged water introduction means 3 (handmade watering can) manufactured in this way was fitted into the opening of the graduated cylinder 1 while keeping it in an inverted state as shown in Fig. 1. The ion-exchanged water was poured in from the cut-off side of the wide-mouth bottle. From the initial foam volume and the foam volume after the addition of ion-exchanged water, the defoaming property (%) shown by the following formula was obtained, and the defoaming property of each liquid detergent composition for hard surfaces was evaluated. The higher the defoaming property, the better the foam disappearance property and the rinsing property of the composition. Defoaming property (%) = [(initial foam volume) - (foam volume after adding 200 ml of ion-exchanged water)] × 100 / (initial foam volume)

[0067] <pH measurement method> The pH at 25°C of the liquid detergent compositions for hard surfaces in each example and comparative example was measured by the glass electrode method. The results are shown in Tables 1 and 2.
