Description

Skin cleanser composition {SKIN CLEANER COMPOSITION}

The present invention relates to skin cleanser compositions.

Since sebum, sunblock cosmetics, and makeup cosmetics on the skin are lipophilic substances, oil-based skin cleanser compositions for removing them are known in the 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 Laid-Open No. 2018-35104

However, since conventional oily skin cleansers have low affinity for water, they have a strong oily feeling during use, and there is room for improvement in terms of washability after use. Moreover, there was room for further improvement also from a viewpoint of contamination removal power.

The present invention has been made in view of the above problems, and its object is to provide a skin cleanser composition that is excellent in feeling of use and washability after use, and also excellent in stain removal power.

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

That is, the present invention includes the following configurations.

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

Component A: Polyethylene glycol

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

Component C: A nonionic surfactant with an HLB value of 19.3 or less.

ADVANTAGE OF THE INVENTION According to this invention, it is possible to provide a skin cleanser composition that is excellent in feeling of use and washability after use, and also excellent in stain removal power.

Although the present invention is described below, the present invention is not limited thereto. The present invention is not limited to each configuration described below, and various changes are possible within the range indicated in the claims. Further, embodiments or examples obtained by appropriately combining technical means disclosed in other embodiments or examples are also included in the technical scope of the present invention. In addition, new technical features can be formed by combining the technical means disclosed in each embodiment. In addition, all of the academic literature and patent literature described in this specification are incorporated as references in this specification.

Unless otherwise specified in this specification, "X to Y" representing a numerical range intends "X or more and Y or less". In addition, unless otherwise indicated in this specification, the mass % which displays content of a component is the value which made 100.0 mass % of the mass of the whole skin cleaning composition.

〔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 to 50.0% by mass, the content of component B is 2.0 to 30.0% by mass, and the content of component C is 1.0 -10.0 mass %;

Component A: Polyethylene glycol

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

Component C: A nonionic surfactant with an HLB value of 19.3 or less.

When the skin cleanser composition contains component A in a predetermined amount, it has excellent compatibility with water, a feeling of use, and washability after use. In this specification, "excellent affinity with water" means that the skin cleanser composition is easily mixed with water. In this specification, “excellent usability” means that the skin cleanser composition exhibits good spreadability when the skin cleanser composition is applied to the skin. In this specification, “excellent wash-off after use” means that the skin cleanser composition adhering 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 the skin cleanser composition.

Because the skin cleanser composition contains component A and component B, the skin cleanser composition can be fused with dirt on the skin, and thus the dirt removal ability is excellent.

When the skin cleanser composition contains component C, the stickiness and oily feeling 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% by mass, preferably 25.0 to 45.0% by mass.

When the content of 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 stain removal power are improved. Moreover, stability of a skin cleanser composition improves as content of component A is less than 50.0 mass %.

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, more preferably 75.0% by mass or more. When the content of component A1 is 50.0% by mass or more, the feeling of use, washability and stain removal power of the skin cleanser composition are further improved, and the skin cleanser composition is easy to achieve a desired viscosity. Moreover, there is no upper limit in particular to content of component A1 in component A, and it may be 100.0 mass %. Moreover, component A may contain polyethylene glycol whose number average molecular weight exceeds 3000 as component A2 for the purpose of viscosity adjustment.

3000 or less are preferable, as for the number average molecular weight of component A1, 2500 or less are more preferable, and 2000 or less are still more preferable. When the number average molecular weight of component A is 3000 or less, the feeling of use, washability and stain 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 glycol of the same molecular weight may be used, or a plurality of polyethylene glycols of molecular weight 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% by mass, preferably 5.0 to 25.0% by mass, and more preferably 8.0 to 20.0% by mass.

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

When the IOB value of component B is 0.1 or more, the feeling of use of the skin cleanser composition is improved, and when it is less than 0.6, the stain removal power when using the skin cleanser composition is improved.

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

IOB = Σ inorganic value / Σ organic value.

The IOB value is obtained by integrating the "inorganic value" and "organic value" of atoms and functional groups constituting organic compounds such as surfactants based on the "inorganic value" and "organic value" set for each atom and functional group. It is a numerical value that can be calculated (refer to Yoshio Koda, "Conceptual Map of Organic Organics-Fundamentals and Applications-", pages 11-17, Sankyo Publishing, 1984).

In addition, the viscosity of component B is preferably 3 to 10000 mPa·s at 20°C, more preferably 5 to 8000 mPa·s. If the viscosity of component B is 3 mPa·s or more, the feeling of use of the skin cleanser composition, especially good fusion at the time of use is obtained. Moreover, when the viscosity is 10000 mPa·s or less, the usability and ductility of the skin cleanser composition are improved.
