Description

  The present invention relates to an emulsifier-type cosmetic, and more particularly to an emulsifier-type cosmetic having a cleansing function and suitable as an aqueous cleansing foam cosmetic.

  The cleansing action in cosmetics usually takes two steps, oil-based face washing and aqueous face-washing. As cosmetics responsible for oil-based face washing, cleansing cosmetics in the form of an oil-in-water emulsifier containing a large amount of liquid oily ingredients. As a cosmetic material that is responsible for an aqueous facial cleansing, there is an aqueous cleaning material that uses soap or an amphoteric surfactant as a cleaning agent. Usually, an aqueous cleaning material is whipped with water, and the resulting foam is used to wash the face. However, in order to save the trouble of whipping, an aqueous carrier is added in advance, and this is spouted with air from a fine hole. Accordingly, pump former cosmetics that are discharged as foam have also appeared.

  As a recent trend in the cosmetics field, simplification of the makeup step is aimed at, and the development of cosmetics with combined functions is promoted for the purpose of satisfying it. For example, massage pack cosmetics (see, for example, Patent Document 1), cleansing pack cosmetics (see, for example, Patent Document 2 and Patent Document 3), and oil-based cleaning materials having a massage function (for example, Patent Document) 4)), etc., but examples of water cleansing agents having a cleansing function and cleansing materials capable of removing aqueous stains are extremely rare. This is because the properties of the raw materials constituting the cosmetics are extensive, and it is extremely difficult to develop a cleaning material that can remove all of these. Even more so, especially in the case of pump foam detergents, which are special forms of water-based facial cleansers. That is, from the viewpoint of simplifying the cosmetic step, it can be said that the development of a pump former aqueous cleaning material capable of removing oily dirt has been desired, but has not been realized.

  On the other hand, it is an aerosol cosmetic that discharges foam using a pump former, and is a cosmetic composition that takes an oil-in-water emulsified form containing 1) liquid oil and fat at 1 atm and 25 ° C., and 2) fatty acid soap. 3) Filled in a pump former container, 4) Cosmetics containing at least two polyglycerin mono-fatty acid esters are not known at all, but cosmetics containing polyglycerin fatty acid esters are not known at all. As a material, application to foaming cosmetics (for example, see Patent Document 5 and Patent Document 6) and cleansing cosmetics (for example, see Patent Document 7) is known. In addition, so-called “pump former containers” that discharge a cosmetic composition in the form of foam by a pump operation are widely used in the cosmetics field, and even commercial products of such containers exist. (For example, see Patent Document 8, Patent Document 9, Patent Document 10, Patent Document 11, and Patent Document 12)

  The cosmetic composition of the present invention obtained by filling the cosmetic composition thus obtained in a pump foamer container is an oil-in-water emulsion, but is ejected in the form of fine bubbles, and is well adapted to aqueous stains. At the same time, the oil and fat contained in the inner phase forms a liquid crystal deformed during foam formation, and the action of removing oily stains is excellent due to the lipophilic substance uptake effect of the liquid crystal.

  Hereinafter, the present invention will be described in more detail with reference to examples, but it is needless to say that the present invention is not limited to such examples.

  According to the formulation shown below, an emulsifier type cosmetic composition 1 which is a cosmetic composition of the present invention was produced. That is, components (a) and (b) were heated to 80 ° C., and (b) was gradually added to emulsify and emulsified with stirring. This was filled in a pump former container to obtain the cosmetic 1 of the present invention.

<Test Example 1>
The cleansing effect of cosmetic 1 was examined. That is, using the eyeliner shown below, the eyeliner was uniformly applied to a 1 cm × 2 cm portion provided on the inner side of the forearm, and 0.1 g of the cosmetic composition 1 that was discharged was thoroughly abraded. Then, after wiping with cut cotton, washing with running water and drying, the color difference (ΔE) from the untreated site was measured. Comparative Example 1 obtained by replacing the diglycerin monolaurate and decaglycerin monooleate of cosmetic 1 with POE (20) oleate, creating a cosmetic composition, and filling it into a pump former, Comparative Example 2 obtained by substituting fatty acid and alkali with POE (45) stearate to prepare a cosmetic composition and filling it into a pump former was also prepared and tested in the same manner. The test results are shown in Table 2. From this, it can be seen that the cosmetic of the present invention is excellent in cleansing action. It can also be seen that this excellent cleansing effect is synergistically produced by the combination of polyglycerin mono-fatty acid ester and fatty acid soap. In Comparative Examples 1 and 2, the discharge state was cream, and no foam was formed.

  Similarly to Example 1, cosmetic composition 2 was prepared according to Table 4 below, and filled into a pump former to obtain cosmetic 2. As for this thing, the color difference was 0.33 by evaluation of Test Example 1, and the color difference was 0.42 by evaluation of Test Example 2. The discharge property was also fine foam. It seems to have the same effect as cosmetic 1.

  Similarly to Example 1, cosmetic composition 3 was prepared according to Table 5 below, and filled into a pump former to obtain cosmetic 3. As for this thing, the color difference was 0.54 by evaluation of Test Example 1, and the color difference was 0.59 by evaluation of Test Example 2. The discharge property was a slightly coarse foam. Although it seems that it has the same effect as the cosmetic 1, the cosmetic 1 is judged to be superior as an effect. From this, it can also be seen that it is preferable to combine two kinds of polyglycerin monofatty acid esters.

  In the same manner as in Example 1, a cosmetic composition 4 was prepared according to Table 6 below and filled in a pump former to obtain a cosmetic 4. As for this thing, the color difference was 0.51 by evaluation of Test Example 1, and the color difference was 0.54 by evaluation of Test Example 2. The discharge property was a slightly coarse foam. Although it seems that it has the same effect as the cosmetic 1, the cosmetic 1 is judged to be superior as an effect. This shows that it is preferable to contain a hydroxy fatty acid.

  In the same manner as in Example 1, a cosmetic composition 5 was prepared according to Table 7 below, and filled into a pump former to obtain a cosmetic 5. As for this thing, the color difference was 0.56 by evaluation of Test Example 1, and the color difference was 0.49 by evaluation of Test Example 2. The discharge property was a slightly coarse foam. Although it seems that it has the same effect as the cosmetic 1, the cosmetic 1 is judged to be superior as an effect. This shows that it is preferable to contain isostearic acid which is a branched fatty acid.

  The present invention can be applied to a foam cosmetic suitable for simplifying the makeup step.
