Description

[Technical Field]

[0001] The present invention relates to a foamy oil cleanser that is excellent in foam quality, foam volume and their persistence, and has excellent cleansing power even when used with wet hands or face. [Background technology]

[0002] Cleansing agents are often used to remove makeup and primarily contain liquid oil as a cleansing ingredient. Commercially available cleansing agents come in a variety of formulations, including oil, cream, emulsion, and gel. Among these, oil-based cleansing agents are commonly referred to as oil cleansers. They typically contain a large amount of liquid oil, making them the most effective at removing makeup and dirt from the skin, making them widely used.

[0003] However, since oil cleansers have a low viscosity, they may drip from the hands or face when applied to the face, and improvements to prevent dripping are needed. One of the methods for improving this is to seal the oil cleanser in an aerosol container equipped with an aerosol valve or nozzle, and spray it from this container to create a foam oil cleanser.

[0004] Patent Document 1 discloses an oily foam aerosol cosmetic that combines a liquid oil component consisting of fats and / or ester oils with a diglycerin fatty acid ester having a hydroxyl group, resulting in excellent composition uniformity, low-temperature stability, foaming properties (foam volume), and foam persistence. However, the foam quality of this aerosol cosmetic is insufficient.

[0005] Patent Document 2 discloses an oily foam aerosol composition that is excellent in cleansing power and usability, leaves a good washing feeling, and also has good foam quality and long-lasting foam, by combining a polyglycerol monoalkyl ether having a degree of polymerization of 2 to 4 and an alkyl chain containing 12 to 18 carbon atoms with fats and oils, and the foam quality has been improved.

[0006] Meanwhile, in recent years, people have started to remove makeup while bathing, and have increasingly used oil cleansers with wet hands and faces. However, previous foam oil cleansers did not have sufficient cleansing power when hands and faces were wet. [Prior art documents] [Patent documents]

If the content of component (d) is too low, not only may the foam quality be reduced, but also the foam persistence may be reduced.

[0030] The foamy oil cleanser of the present invention contains at least the above components (a) to (d), and the total content of components (a) to (d) is preferably 70% by mass or more, more preferably 80% by mass or more, and even more preferably 90% by mass or more, when the total amount of the foamy oil cleanser is taken as 100% by mass, with the upper limit being 100% by mass.

[0031] [Other ingredients] The foamy oil cleanser of the present invention may contain, in addition to the above-mentioned components, additives used in cosmetics, quasi-drugs, pharmaceuticals, etc., as needed, to the extent that the effects of the present invention are not impaired. For example, natural fragrances and synthetic fragrances may be added to enhance palatability.

[0032] The foam oil cleanser of the present invention may also contain water. Purified water is usually used as the water, and is used for the purpose of adjusting the content of each component. When the total amount of the foam oil cleanser is taken as 100% by mass, the water content is preferably 30% by mass or less, more preferably 20% by mass or less, and even more preferably 10% by mass or less, with the lower limit being 0% by mass.

[0033] [Aerosol container] The foam oil cleanser of the present invention (hereinafter also referred to as "cleansing agent") is enclosed in an aerosol container and sprayed from the aerosol container to form a foam. The aerosol container comprises at least a pressure-resistant container, an aerosol valve, and a nozzle.

[0034] The pressure-resistant container may be made of, for example, a metal such as aluminum or tinplate, a synthetic resin such as polyethylene terephthalate, or glass, and may be shaped like a cylinder with a bottom and an opening at the top.

[0035] The aerosol valve can be an aerosol valve commonly used in aerosol containers, such as one comprising a valve mechanism, a housing for accommodating the valve mechanism, and a mounting member for holding the housing in a predetermined position in the pressure-resistant container and fastening it to the opening of the pressure-resistant container. The valve mechanism, for example, comprises a stem, a stem gasket for closing the stem hole, and a spring for biasing the stem upward; when the stem moves downward against the spring, the stem hole opens, connecting the inside and outside of the pressure-resistant container. The housing has a housing hole for taking in the cleansing agent from the pressure-resistant container, and a dip tube extending to the bottom of the pressure-resistant container is connected to the housing hole. This allows the cleansing agent from the pressure-resistant container to pass through the dip tube and be supplied to the gap between the housing and the stem.

[0036] The nozzle is a component attached to the pressure-resistant container via the aerosol valve. The nozzle has a passage through which the cleansing agent passes after being taken in from the pressure-resistant container via the stem hole of the aerosol valve, and an ejection port through which the cleansing agent is ejected to the outside.

[0037] When the user pushes the nozzle downward against the spring, the stem also moves downward, opening the stem hole and connecting the inside of the pressure container to the outside. This opening causes the pressure of the gaseous propellant inside the pressure container to force the cleanser through the dip tube, housing hole, and stem hole, and then spray out through the nozzle's nozzle. The cleanser sprayed out forms a foam due to the rapid expansion of the propellant caused by the reduced pressure.

[0038] The foam oil cleanser of the present invention can be produced by a conventional method. For example, the ingredients other than component (d) are appropriately heated, stirred and mixed, cooled to room temperature, and then water is added as needed, and the mixture is filled into a pressure-resistant container. After component (d) is further filled into the pressure-resistant container, the mounting member of the aerosol valve is fixed to the opening of the pressure-resistant container, thereby producing a foam oil cleanser sealed in an aerosol container. [Example]

[0039] [Examples 1 to 10. Refer to Examples 1 and 2 and Comparative Examples 1 to 5] <Preparation of foam oil cleanser> Foam oil cleansing agents were prepared by the following method using the blending ratios shown in Tables 1 and 2.

[0041] <Evaluation of foam oil cleansing products> The foamy oil cleansing agents thus prepared were evaluated for the following four items. The evaluation results are shown in Tables 1 and 2.

[0042] [Evaluation items and criteria] The panelists judged the following items and gave a four-level rating from "◎" to "×" based on the total score of each item according to the following criteria. There were 20 panelists who judged items (1), (2), and (3). <4-level evaluation criteria based on the total score> ◎: Total score is 35 points or more ○: Total score is between 20 and 35 points △: Total score is between 5 and 20 points ×: Total points are less than 5 points

[0043] (1) Foam quality The foam oil cleanser was ejected from the aerosol container for 5 seconds, and the fineness of the foam was visually confirmed and rated as follows: 2 points: If the bubbles are fine. 1 point: The foam is slightly coarse. 0 points: If the foam is coarse.

[0044] (2) Foam volume The foam oil cleanser was discharged from the aerosol container for 5 seconds, and the amount of foam was visually confirmed and rated as follows. 2 points: If there is a lot of foam. 1 point: When the amount of foam is slightly too much. 0 points: When there is little foam.

[0045] (3) Durability of foam The foam oil cleanser was ejected from the aerosol container for 5 seconds, and the foam quality and amount were visually checked after 30 seconds and rated as follows: 2 points: The foam is fine and there is a lot of foam. 1 point: The foam is coarse or there is little foam. 0 points: When the foam is almost completely liquefied.

[0046] (4) Cleansing power when hands and face are wet Twenty female panelists (aged 25-45) wearing makeup (eyeliner) were asked to wet their palms with 0.5g of water and their makeup-covered skin with 0.5g of water. 3g of foam oil cleanser was placed in the wetted hands and massaged into the skin. Similarly, 3g of foam oil cleanser was also used on dry hands and skin without wetting them. The cleansing power of the product when the hands and face were wet was compared to that when the hands and face were dry, and the results were evaluated as follows: 2 points: If you feel that the cleansing power is the same as when your hands and face are dry. 1 point: If you feel that the cleansing power is slightly weaker than when your hands or face are dry. 0 points: If you feel that the cleansing power is weaker than when your hands or face are dry.

[0047] [Table 1]

[0048] [Table 2]

[0049] [Table 3]

[0050] Example 1 10 From these results, it can be seen that all of the foamy oil cleansing agents of the present invention had good foam quality, foam volume, foam persistence, and cleansing power when the hands or face were wet. On the other hand, Comparative Examples 1 to 5 do not provide sufficient performance. Comparative Example 1, which did not contain component (a), Comparative Example 2, which did not contain component (b), and Comparative Example 3, in which component (b) was changed to PEG-8 oleate, were insufficient in terms of foam quality, foam volume, foam persistence, and cleansing power when hands or face were wet. Furthermore, in Comparative Example 4, which did not contain component (c), the amount of foam and foam persistence were insufficient, and in Comparative Example 5, in which component (c) was changed to diglyceryl oleate, the foam quality, foam persistence, and cleansing power when hands or face were wet were insufficient. [Industrial Applicability]

[0051] The foamy oil cleanser of the present invention is excellent in foam quality, foam volume, and foam durability, and can therefore be suitably used as a cleanser for removing makeup such as eyeliner. In particular, the foamy oil cleanser of the present invention has excellent cleansing power even when used with wet hands or face, and can therefore be used to remove makeup while bathing.
