Description

Technical Field

[0001] The present invention relates to a foam-like skin cleansing agent.

Background Art

[0002] Cleansing cosmetics aimed at removing makeup cosmetics can be roughly classified into oil-based cleansing cosmetics and water-based cleansing cosmetics.

[0003] Since oil-based cleansing cosmetics contain a large amount of oil components, they have good compatibility with makeup dirt and exhibit excellent cleansing power. On the other hand, there are drawbacks such as the once-emerged makeup dirt reattaching to the skin or a sticky feeling peculiar to oil components remaining on the skin after cleansing, resulting in a poor user experience.

[0004] On the other hand, water-based cleansing cosmetics contain a small amount of oil components, so they provide a refreshing user experience. However, they have the drawback of not having good compatibility with makeup dirt and being inferior in cleansing power.

[0005] Water-based cleansing cosmetics contain various surfactants and oils. As surfactants with excellent makeup removal effects (cleansing power), polyoxyethylene glycerin fatty acid esters and the like are known (for example, Patent Document 1).

[0006] In addition, foam-like skin cleansing agents with excellent cleansing power such as polyoxyethylene glycerin fatty acid esters have been proposed (for example, Patent Documents 2 and 3).

[0008] However, foam-type skin cleansers containing polyoxyethylene glycerin fatty acid esters had room for improvement in terms of foam texture.

[0009] Therefore, the object of the present invention is to provide a foamy skin cleanser that achieves both excellent cleansing power and a good foamy texture (stringiness and spreadability). [Means for solving the problem]

[0010] The inventors of the present invention conducted diligent research to solve the above problems and, as a result, discovered that by incorporating specific components in specific amounts into a foamy skin cleanser, it is possible to achieve both excellent cleansing power and a good foamy texture (stringiness and spreadability), thus completing the present invention.

[0011] Accordingly, one aspect of the present invention is a foamy skin cleanser in which an aerosol composition comprising a stock solution and a propellant is filled into an aerosol container, wherein the stock solution contains the following components A to D, with component A having a content of 3.0 to 12.0% by mass, component B having a content of 0.5 to 5.0% by mass, component C having a content of 0.008 to 0.120% by mass, and the propellant contains liquefied petroleum gas, and is a foamy skin cleanser (hereinafter referred to as "this skin cleanser"): Component A: polyoxyethylene glycerin fatty acid ester, Component B: amphoteric surfactant, Component C: polyethylene glycol with a number average molecular weight of 1.5 million to 7.5 million, Component D: water. [Effects of the Invention]

[0012] According to the present invention, it is possible to provide a foamy skin cleanser that combines excellent cleansing power with a good foamy texture (stringiness and spreadability). [Modes for carrying out the invention]

[0013] One embodiment of the present invention will be described in detail below. Unless otherwise specified in this specification, "A to B" representing a numerical range means "greater than or equal to A and less than or equal to B". Furthermore, all references cited in this specification are incorporated herein by reference.

[0014] [1. Outline of the present invention] As mentioned above, foam-type skin cleansers containing polyoxyethylene glycerin fatty acid esters had poor foam texture and presented challenges in terms of usability. Specifically, foam-type skin cleansers containing polyoxyethylene glycerin fatty acid esters would break down upon contact with makeup and other dirt on the skin. As a result, the unique benefit of foam-type cleansers—that they allow the foam to spread on the skin, reducing resistance to the skin and allowing for comfortable blending with makeup—was not fully realized, making it difficult to blend with a sufficient area of ​​makeup on the skin. In short, it was difficult to achieve both the excellent cleansing power of polyoxyethylene glycerin fatty acid esters and a good foam texture.

[0015] Therefore, the present inventors conducted diligent research with the aim of providing a foam-type skin cleanser that combines excellent cleansing power with a good foam texture using polyoxyethylene glycerin fatty acid ester. As a result, they discovered for the first time that it is possible to achieve both excellent cleansing power and a good foam texture in a foam-type skin cleanser by incorporating specific components in specific amounts.

[0016] A foamy skin cleanser containing polyoxyethylene glycerin fatty acid ester that combines excellent cleansing power with a pleasant foamy texture is unprecedented and extremely useful in the field of cosmetics.

[0017] [2. Foam-type skin cleanser] This skin cleanser is a foam-type skin cleanser in which an aerosol composition consisting of a concentrate and a propellant is filled into an aerosol container.

[0018] (Undiluted solution) The undiluted solution in the aerosol composition of this skin cleanser contains the following components A to D: Component A: Polyoxyethylene glycerin fatty acid ester Component B: Amphoteric surfactant Component C: Polyethylene glycol with a number average molecular weight of 1.5 million to 7.5 million Component D: Water.

[0019] This skin cleanser can achieve both excellent cleansing power and good foam texture by containing the undiluted solution in specific amounts of the above components A to D.

[0022] The polyoxyethylene glycerin fatty acid ester may be used alone as one of the above, or two or more of them may be used in appropriate combination. From the perspective of cleansing power, preferably, two or more are used.

[0023] The content of polyoxyethylene glycerin fatty acid ester in the stock solution is 3.0 to 12.0% by mass, preferably 4.0 to 9.0% by mass, and more preferably 6.0 to 8.0% by mass. When the content is 3.0% by mass or more, the cleansing power is excellent. When the content is 12.0% by mass or less, the foam stability (persistence) is excellent.

[0024] In one embodiment of the present invention, the number of moles of ethylene oxide added to the polyoxyethylene glycerin fatty acid ester is preferably 4 to 30, more preferably 4 to 20, and even more preferably 5 to 10. When the number of moles added is 4 or more, the formulation stability is excellent. Furthermore, when the number of moles added is 30 or less, the cleansing power is excellent.

[0025] <Component B> The undiluted solution of this skin cleanser contains an amphoteric surfactant. The inclusion of an amphoteric surfactant in the undiluted solution of this skin cleanser results in excellent foam texture (stringiness and spreadability).
