Description

Technical Field

[0001] The present invention relates to a cleaning agent composition for a former.

Background Art

[0002] In recent years, products that fill a cleaning agent composition into a non-gas type foam discharge container such as a pump former and discharge it in a foamy state during use have increased because they can save the trouble of foaming and easily obtain creamy foam. This type of cleaning agent composition forms foam by mixing the cleaning composition and air by passing through a porous membrane inside the container. However, there is a problem that the cleaning agent composition clogs the porous membrane of the pump former, and particularly when a higher fatty acid salt having 14 or more carbon atoms is used, clogging occurs remarkably due to precipitation during low-temperature storage.

[0003] As means for solving such problems, a cleaning agent composition combining a specific polyoxyethylene alkyl ether type nonionic surfactant and a higher fatty acid salt (for example, Patent Document 1), a cleaning agent composition combining a higher fatty acid salt and a specific amphoteric surfactant (for example, Patent Document 2), and a foam discharge cleaning agent composition combining a higher fatty acid salt, an amphoteric surfactant, and alkyl polyglucoside (for example, Patent Document 3) have been provided.

[0004] However, in these cleaning agent compositions, in order to suppress clogging of the porous membrane, the content of palmitate or stearate that realizes creamy foam quality among higher fatty acid salts is suppressed, and since the generation of metal soap is reduced, a refreshing feeling during rinsing peculiar to fatty acid soap cannot be obtained. In addition, since the foam quality is ensured by blending a large amount of an amphoteric surfactant or alkyl polyglucoside, there is a problem that stickiness peculiar to the surfactant also occurs.

[0006] Against such a background, there is a demand for a cleaning agent composition for a former that has good dischargeability at low temperatures and no stickiness during flushing.

[0007] The present invention has been made in view of the above problems, and an object thereof is to provide a cleaning agent composition for a former that has good dischargeability at low temperatures and no stickiness during flushing in a cleaning agent discharged from a foam discharge container such as a pump former. [Means for Solving the Problems]

Embodiments for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described in detail, but the present invention is not limited to the following embodiments. The present invention is not limited to each configuration described below, and various modifications are possible within the scope shown in the claims. Embodiments and examples obtained by appropriately combining the technical means disclosed in different embodiments and examples are also included in the technical scope of the present invention. Also, in this specification, unless otherwise specified, "A to B" representing a numerical range is intended to mean "A or more and B or less".

[0012] In this specification, the "dischargeability at low temperatures" means that it is difficult for the pump to become clogged even at low temperatures, for example, 0°C, and the former can be easily discharged from the former container.

[0013] The cleaning agent composition for a former according to this embodiment is a cleaning agent composition for a former that is filled in a foam discharge container and used, and contains (A) a fatty acid salt and (B) a polyalkyl glucoside. The (A) component contains (A-1) myristate at 40% by mass or more based on the total fatty acid salts, (A-2) palmitate, and (A-3) stearate at 4% by mass or more based on the total fatty acid salts.

[0014] <(A) component> The component (A) used in the detergent composition according to this embodiment is a fatty acid salt. The component (A) is not particularly limited as long as it is a fatty acid salt. From the viewpoint of skin irritation, it is preferably a higher fatty acid salt. The fatty acid constituting the higher fatty acid salt is preferably a saturated fatty acid having 8 to 22 carbon atoms.

[0016] In the cleaning agent composition for a former according to this embodiment, the blending amount of the fatty acid salt as the component (A) is preferably 4 to 15% by mass, more preferably 6 to 10% by mass, based on the entire cleaning agent composition. If the blending amount of the component (A) is 4% by mass or more based on the entire cleaning agent composition, a creamy foam quality with a sufficiently fine texture can be obtained. On the other hand, if the blending amount of the component (A) is 15% by mass or less based on the entire cleaning agent composition, clogging of the mesh inside the foam discharge container such as a pump former can be suppressed.

[0017] The component (A) of the cleaning agent composition for a former according to this embodiment includes (A-1) myristate, (A-2) palmitate, and (A-3) stearate.

[0018] In the cleaning agent composition for a former according to this embodiment, the blending amount of the myristate as the component (A-1) is 40% by mass or more based on all fatty acid salts. From the viewpoint of suppressing clogging of the mesh inside the foam discharge container, the blending amount of the component (A-1) is preferably 40 to 60% by mass based on all fatty acid salts. If the content of the component (A-1) is 40% by mass or more based on all fatty acid salts, a creamy foam quality with a fine texture can be obtained without stickiness during rinsing.

[0019] In the cleaning agent composition for a former according to this embodiment, the palmitate as the component (A-2) makes the foam quality creamy, and its blending amount is not limited. From the viewpoint of the creaminess of the foam quality, the blending amount of the component (A-2) is preferably 4 to 10% by mass based on all fatty acid salts.

[0020] In the detergent composition for a former according to this embodiment, the blending amount of the stearate which is the component (A-3) is 4 mass% or more with respect to the total fatty acid salts. From the viewpoint of suppressing clogging at the mesh inside the foam discharge container, the blending amount of the component (A-3) is preferably 4 to 10 mass% with respect to the total fatty acid salts. If the content of the component (A-3) is 4 mass% or more with respect to the total fatty acid salts, stickiness during rinsing does not occur.

[0021] <Component (B)> The component (B) used in the detergent composition for a former according to this embodiment is alkyl polyglucoside. By including alkyl polyglucoside in the detergent composition for a former according to this embodiment, the creaminess of the foam discharged from the foam discharge container is improved. Specific examples of alkyl polyglucoside include decyl glucoside, lauryl glucoside, myristyl glucoside, cocooyl glucoside and the like. These alkyl polyglucosides can be commercially available products. Specific examples of commercially available products include Midol 10, Midol 12 (both manufactured by Kao Corporation), Plantacare 2000UP, Plantacare 1200UP, Plantacare 818UP, Plantacare 800UP and other Plantacare series (all manufactured by BASF Corporation) and the like. In the detergent composition for a former according to this embodiment, these alkyl polyglucosides can be used alone or in combination of two or more.

[0022] In the detergent composition for a former according to this embodiment, the blending amount of the alkyl polyglucoside which is the component (B) is preferably 0.5 to 2 mass% with respect to the whole detergent composition. If the blending amount of the component (B) is 0.5 mass% or more with respect to the whole detergent composition, the creaminess of the foam quality can be improved. Also, if the blending amount of the component (B) is 2 mass% or less with respect to the whole detergent composition, stickiness during rinsing can be made less likely to occur.
