Description

Skin cleanser composition {SKIN CLEANSER COMPOSITION}

The present invention relates to a skin cleanser composition.

Since sebum on the skin, sunblock cosmetics, and makeup cosmetics are lipophilic substances, oily skin cleanser compositions for removing them are known as prior art. For example, Patent Document 1 describes an oily skin cleanser composition containing a diester of dimer acid, a predetermined surfactant, ethanol, a volatile silicone, and a predetermined ester oil.

Japanese Patent Publication No. 2018-35104

However, since conventional oily skin cleansers have low affinity with water, the oily feeling during use is strong, and there is room for improvement from the viewpoint of washability after use. In addition, there was room for further improvement from the viewpoint of contamination removal power.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a skin cleanser composition having excellent feeling of use and washability after use, and also excellent in removing dirt.

In order to solve the above problems, the present inventors intensively studied, and found that a skin cleanser composition using a specific amount of polyethylene glycol, ester oil, and surfactant was excellent in feeling in use, washability after use, and dirt removal power.

That is, the present invention includes the following configurations.

A skin cleanser composition containing the following components A to C, the content of component A is 20.0 to 50.0 mass%, the content of component B is 2.0 to 30.0 mass%, and the content of component C is 1.0 to 10.0 mass%.

Component A: polyethylene glycol

Component B: Ester oil with an IOB value of 0.1 to 0.6

Component C: Nonionic surfactant having an HLB value of 19.3 or less.

Advantageous Effects of Invention According to the present invention, it is possible to provide a skin cleanser composition that is excellent in feeling in use and washability after use, and also excellent in soil removal power.

The present invention will be described below, but the present invention is not limited thereto. The present invention is not limited to each configuration described below, and various modifications are possible within the scope shown in the claims. Further, embodiments or examples obtained by appropriately combining the technical means disclosed in each of the other embodiments or examples are also included in the technical scope of the present invention. Further, by combining the technical means disclosed in each of the embodiments, a new technical characteristic can be formed. In addition, all of the academic literature and patent literature described in this specification are used as a reference in this specification.

In the present specification, "X to Y" indicating a numerical range is intended as "X or more and Y or less" unless otherwise specified. In addition, in the present specification, the mass% indicating the content of the component is a value obtained by making the total mass of the skin cleanser composition 100.0 mass%.

〔One. Skin cleanser composition]

The skin cleanser composition according to the present invention contains the following component A, component B, and component C, the content of component A is 20.0-50.0 mass%, the content of component B is 2.0-30.0 mass%, and the content of component C is 1.0. -10.0 mass%;

Component A: polyethylene glycol

Component B: ester oil with an IOB value of 0.1 or more and less than 0.6

Component C: Nonionic surfactant having an HLB value of 19.3 or less.

When the skin cleanser composition contains the component A in a predetermined content, it is excellent in affinity with water, a feeling of use, and washability after use. In the present specification, "excellent in affinity with water" means that the skin cleanser composition is easily mixed with water. In the present specification, "excellent feeling in use" means that the skin cleanser composition exhibits good application properties when the skin cleanser composition is applied to the skin. In the present specification, "excellent washing after use" means that the skin cleanser composition adhered to the skin is easily washed off with water or the like. In addition, component A can also be used for the purpose of adjusting the viscosity of a skin cleanser composition.

Since the skin cleanser composition contains the component A and the component B, since the skin cleanser composition can be fused with the dirt on the skin, the dirt removal power is excellent.

When the skin cleanser composition contains the component C, stickiness and oiliness caused by the oily component after use can be reduced. That is, after using the skin cleanser composition according to the present invention, a good finish without stickiness can be obtained.

<Component A>

The skin cleanser composition contains polyethylene glycol as component A. The content of component A is 20.0 to 50.0 mass%, preferably 25.0 to 45.0 mass%.

When the content of the component A is 20.0% by mass or more, the affinity of the skin cleanser composition with water is improved, so that the feeling of use, washability, and dirt removal power are improved. Moreover, if the content of the component A is within 50.0 mass%, the stability of the skin cleanser composition is improved.

Component A preferably contains polyethylene glycol having a number average molecular weight of 200 to 3000 as component A1. The content of component A1 in component A is preferably 50.0% by mass or more, and more preferably 75.0% by mass or more. When the content of the component A1 is 50.0% by mass or more, the feeling of use, washability, and dirt removal power of the skin cleanser composition are further improved, and the skin cleanser composition is easily made to a desired viscosity. Moreover, there is no upper limit in particular to the content of component A1 in component A, and 100.0 mass% may be sufficient. Moreover, component A may contain polyethylene glycol with a number average molecular weight exceeding 3000 as component A2 for the purpose of viscosity adjustment.

The number average molecular weight of component A1 is preferably 3000 or less, more preferably 2500 or less, and even more preferably 2000 or less. When the number average molecular weight of component A is 3000 or less, the feeling of use, washability, and dirt removal power are improved. Moreover, 200 or more are preferable and, as for the number average molecular weight of component A, 500 or more are more preferable.

As component A, only polyethylene glycols having the same molecular weight may be used, or polyethylene glycols having a plurality of molecular weights may be mixed.

<Component B>

The skin cleanser composition contains ester oil as component B. The content of component B is 2.0 to 30.0 mass%, preferably 5.0 to 25.0 mass%, and more preferably 8.0 to 20.0 mass%.

When the content of the component B is 2.0 mass% or more, the contamination removal power is improved. Moreover, when the content of the component B is 30.0% by mass or less, the feeling of use of the skin cleanser composition and washability after using the skin cleanser composition are improved.

The IOB value of component B is 0.1 or more and less than 0.6, preferably 0.1 to 0.5. If the IOB value of component B is 0.1 or more, the feeling of use of the skin cleanser composition is improved, and if it is less than 0.6, the dirt removal power when the skin cleanser composition is used is improved.

Here, the IOB (Inorganic-Organic Balance) value is a value expressed by the following equation:

IOB=Σ inorganic value/Σ organic value.

The IOB value is based on the ``inorganic value'' and ``organic value'' set for various atoms and functional groups, by integrating the ``inorganic value'' and ``organic value'' of the atoms and functional groups constituting organic compounds such as surfactants. It is a numerical value that can be calculated (refer to Yoshio Koda, 「Organic Conceptual Map-Basics and Applications-」, pages 11 to 17, published in Sankyo, published in 1984).

In addition, the viscosity of component B is preferably 3 to 10000 mPa·s, and more preferably 5 to 8000 mPa·s at 20°C. When the viscosity of component B is 3 mPa·s or more, a feeling of use of the skin cleanser composition, particularly good fusion during use is obtained. Moreover, when the viscosity is 10000 mPa·s or less, the feeling of use and softness of the skin cleanser composition are improved.
