Description

  The present invention relates to an aqueous cleansing cosmetic for removing makeup stains, and more specifically, a sucrose fatty acid ester and one selected from disodium monohydrogen phosphate, sodium dihydrogen phosphate, and sodium phosphate. Or an aqueous cleansing cosmetic containing two or more kinds and a saponin-containing plant extract, which is excellent in makeup removing ability, hardly causes stickiness of the back skin, and further has excellent storage stability. It is about.

  Cleansing cosmetics for removing makeup stains are mainly oily products represented by cleansing oils, emulsified products represented by cleansing creams, and water-based products represented by cleansing lotions. It can be roughly divided into types. Of these, oily and emulsified type liquid oily components contained in large amounts dissolve the makeup stains and float the stains. Since the oil film remains, there is a difficulty that it is difficult to meet the needs of consumers seeking a fresh feeling of use. On the other hand, an aqueous cleansing material having a small amount of oil component and having a surfactant and an aqueous medium as main components is excellent in fresh feeling, and therefore easily matches the above-mentioned consumer needs. Moreover, since the viscosity is low if it is a cleansing lotion, makeup stains can be easily removed by simply wiping it with cotton, and in recent years the preference for this ease has increased.

In the case of aqueous cleansing cosmetics, the surfactant, mainly the nonionic surfactant, floats the makeup stains and removes it by wiping or washing away, so the selection of this nonionic surfactant is very important. Nonionic surfactants having one or more polyoxyalkylene groups such as polyoxyethylene groups and polyoxypropylene groups as nonionic surfactants that have been widely used in this aqueous cleansing cosmetic. Agents. Nonionic surfactants having a polyoxyalkylene group have been widely used in aqueous cleansing cosmetics because of their high solubility in aqueous media and excellent makeup removal ability to lift makeup off. (For example, patent document 1).
On the other hand, the above-mentioned nonionic surfactants having polyoxyalkylene groups are mainly originated from naphtha, and these have recently been reduced from the viewpoint of the future depletion of petroleum resources and supply concerns accompanying the international situation. Technological development of cleansing materials that are not used has been widely performed (for example, Patent Document 2 and Patent Document 3).

Japanese Patent Laid-Open No. 2001-270809 JP 2006-56856 A Japanese Patent Laid-Open No. 2002-363062

However, when a nonionic surfactant having a polyoxyalkylene group is used in the aqueous cleansing material (Patent Document 1), there is a problem that stickiness derived from the polyoxyalkylene group occurs on the back skin after cleansing. there were. In addition, nonionic surfactants with polyoxyalkylene groups are largely affected by dependence on petroleum resources, supply instability due to the international situation, and price fluctuations as described above. It was an issue.
On the other hand, the technique of Patent Document 2 does not use a nonionic surfactant having a polyoxyalkylene group, but instead uses a polyglycerin-based nonionic surfactant as an essential component. Similar to the case of using a nonionic surfactant having an oxyalkylene group, there is a problem that the back skin becomes sticky.
In the technique of Patent Document 3, sucrose fatty acid ester is used in place of the nonionic surfactant having a polyoxyalkylene group, which is excellent in that it is less likely to cause stickiness of the back skin. Compared with a cleansing material using a nonionic surfactant having an oxyalkylene group, the makeup removing ability was inferior and was not satisfactory.

  For this reason, there has been a demand for the development of an aqueous cleansing cosmetic that is excellent in makeup removing ability, hardly causes stickiness of the back skin, and has excellent storage stability. Moreover, the necessity of the water-based cleansing cosmetic which does not use the nonionic surfactant which has a polyoxyalkylene group from the various situations surrounding raw material supply has also increased.

  In such a situation, the present inventor has intensively studied to solve the above problems, and as a result, among inorganic salts widely used as a pH adjuster, monosodium monohydrogen phosphate, sodium dihydrogen phosphate, and phosphoric acid. It has been found that sodium is excellent in makeup removing ability. Then, in combination with these inorganic salts, the nonionic surfactant which improves makeup removal ability and dissolution stability dramatically was examined, and it discovered that sucrose fatty acid ester was preferable. By further studying and combining these with a saponin-containing plant extract, it is possible to improve the makeup removal ability, to prevent stickiness of the back skin, and to obtain an aqueous cleansing cosmetic with excellent storage stability. The headline and the present invention were completed.

That is, the present invention includes the following components (A) to (C);
(A) Sucrose fatty acid ester 0.1-2.0 mass%
(B) 1 type, or 2 or more types selected from disodium monohydrogen phosphate, sodium dihydrogen phosphate, and sodium phosphate 0.001 to 2.0 mass%
(C) It is related with the aqueous cleansing cosmetic characterized by containing a saponin containing plant extract.

  Furthermore, the present invention relates to an aqueous cleansing cosmetic characterized in that the sucrose fatty acid ester of component (A) is sucrose laurate.

  Further, the present invention relates to an aqueous cleansing cosmetic characterized in that the saponin-containing plant extract of component (C) is one or two or more selected from savonso, mukuroji, horsetail, maronier, hamamelis, eucalyptus, and ages.

  Furthermore, the present invention relates to an aqueous cleansing cosmetic characterized by not containing a nonionic surfactant having a polyoxyalkylene group.

  Furthermore, the present invention relates to an aqueous cleansing cosmetic characterized in that the content of the oil component is less than 1.0% by mass.
