Description

  The present invention relates to a cosmetic, and more particularly to an emulsifier-type cosmetic suitable for massage.

  Cosmetics for massage are interposed at the time of rubbing treatment for massage treatment to reduce the friction coefficient in order to prevent the rubbing site from feeling irritation due to friction between the finger and the rubbing site during the rubbing treatment. As a dosage form of cosmetics, oil dosage forms, high internal phase oil-in-water emulsifier forms, aqueous gel dosage forms, non-aqueous gel dosage forms, and the like are known. The oil dosage form has the advantage that the friction reducing function is stable for a long time, but there are drawbacks such as dripping and oily feel after massage. In the emulsifier form, an aqueous additive component, oily Although it can be made into a dosage form with added ingredients and has the advantage of being able to perform skin care while massaging, the emulsification system is reversed during the rubbing treatment, and the coefficient of friction changes greatly during the reversal, resulting in a comfortable rubbing treatment. There are disadvantages that can have undesirable effects. The aqueous gel dosage form does not feel oily at the time of rubbing, there is no change in the coefficient of friction due to inversion, and it has the advantage that cosmetics can be easily removed after massaging. There are drawbacks such as rising, less emollient effect, feeling cold at the start of massage, and not increasing the level of comfort. Although the non-aqueous gel dosage form has an advantage that a warm feeling can be imparted, there are merits and demerits in each dosage form, for example, the effect of reducing the coefficient of friction is low and there is a problem in the level of improvement in comfort. In massage treatments in esthetics, the first purpose is to give comfort, and the second purpose is to remove oily and protein soils that have accumulated in pores, etc. As the massage material, a massage preparation that has little change in the coefficient of friction at the time of rubbing and can remove both oily soil and aqueous soil such as protein is suitable. From such a viewpoint, it can be said that gently improving the reversal in the emulsifier type massage material leads to an improvement in the duration of comfort and can be suitably used for esthetic treatment.

  On the other hand, (adipic acid, 2-ethylhexanoic acid, stearic acid) glyceryl oligoester is known as a nonionic surfactant for cosmetics (see, for example, Patent Document 1). Not known at all. Polyethylene glycol (100-200) difatty acid ester such as polyethylene glycol (150) distearate is also known as a raw material for cosmetics (see, for example, Patent Document 2), but its application to massage materials is quite known. Not. Therefore, it is possible to make a massage material suitable for maintaining comfort by making such a composition that these two are combined and contained in a cosmetic for massage, by taking such a configuration. There was nothing known to be able to do it.

JP 2003-286126 A JP 2002-47123 A

  The present invention has been made under such circumstances, and an object of the present invention is to provide a technique for improving the duration of comfort during rubbing in an emulsifier-type cosmetic.

In view of such a situation, as a result of repeated earnest research efforts in the emulsifier type cosmetics, the present inventors have sought for a technique for improving the duration of comfort during rubbing. 100-200) Emulsifier-type cosmetics containing difatty acid ester and 2) (adipic acid, 2-ethylhexanoic acid, stearic acid) glyceryl oligoester have been found to have such properties, The invention has been completed. That is, the present invention is as follows.
(1) An emulsifier type cosmetic comprising 1) polyethylene glycol (100 to 200) difatty acid ester and 2) (adipic acid, 2-ethylhexanoic acid, stearic acid) glyceryl oligoester.
(2) The cosmetic according to (1), wherein the content of the polyethylene glycol (100 to 200) difatty acid ester is 0.01 to 0.5% by mass.
(3) The content of (adipic acid, 2-ethylhexanoic acid, stearic acid) glyceryl oligoester is 0.1 to 10% by mass, according to (1) or (2) Cosmetics.
(4) The cosmetic according to any one of (1) to (3), further comprising diglycerin tetraoleate.
(5) The cosmetic according to any one of (1) to (4), which is a cosmetic for massage.
(6) The cosmetic according to (5), wherein the massage is a massage in esthetic treatment.
(7) The cosmetic according to any one of (1) to (6), wherein the cosmetic can be removed by wiping off a steamed towel.

  ADVANTAGE OF THE INVENTION According to this invention, the technique which improves the duration of the comfort at the time of rubbing can be provided in the emulsifier type cosmetics.

(1) Polyethylene glycol (100 to 200) difatty acid ester which is an essential component of the cosmetic of the present invention The cosmetic of the present invention contains polyethylene glycol (100 to 200) difatty acid ester as an essential component. To do. The polyethylene glycol moiety constituting this component is preferably 100 to 200, more preferably 120 to 180, in terms of the degree of polymerization of polyoxyethylene. The fatty acid residue is not particularly limited, but is preferably a saturated or unsaturated fatty acid having 10 to 30 carbon atoms and may have a branch. Specifically, lauric acid residue, myristic acid residue, palmitic acid residue, stearic acid residue, behenic acid residue, oleic acid residue, linoleic acid residue, linolenic acid residue, isostearic acid residue, Preferred examples include octyldodecanoic acid residues. Particularly preferred is a stearic acid residue. As a particularly preferred compound, polyethylene glycol (150) distearate can be exemplified. Some of these components are already on the market, and such commercial products can be purchased and used.

  In the cosmetic composition of the present invention, such components work together with glyceryl oligoesters described later (adipic acid, 2-ethylhexanoic acid, stearic acid) to gently reverse the inversion at the time of rubbing, and the friction coefficient increases rapidly with the inversion. It has the effect of making the skin feel moderately comfortable irritation. In order to exhibit such an effect, the polyethylene glycol (100 to 200) difatty acid ester can be contained alone or in combination of two or more. Moreover, as content for exhibiting such an effect, the total amount is preferably 0.01 to 0.5% by mass, more preferably 0.05 to 0.3% by mass with respect to the total amount of the cosmetic. It is. This is because if the amount is too large, the change in the friction coefficient may be large, and if the amount is too small, the smoothing effect of reversal may not be obtained.

(2) (Adipic acid, 2-ethylhexanoic acid, stearic acid) glyceryl oligoester which is an essential component of the cosmetic of the present invention It contains an ester as an essential component. This component is an oligoester in which adipic acid, 2-ethylhexanoic acid, and stearic acid are randomly ester-bonded to glycerin, and there is also a portion that forms a crosslinked structure via adipic acid, which is a dibasic acid. Is a large ester. Such components have already been used as raw materials for cosmetics, and there are commercially available products. Examples of preferable commercial products include “NOMCOAT LAH” sold by Nisshin Oilio Co., Ltd. This component works together with the diglyceride ester of polyethylene glycol, has the effect of adjusting the timing of reversal at the time of rubbing in massage, and at the same time has the effect of creating a pleasant stimulus on the skin by rubbing with a slight adhesion . In order to express such an action, it is preferable to contain 0.1 to 10% by mass of such a component with respect to the total amount of the cosmetic, and more preferably 1 to 5% by mass.

(3) Cosmetics of this invention The cosmetics of this invention contain the said essential component, It is an emulsifier form, It is characterized by the above-mentioned. The emulsifier form is preferably an oil-in-water emulsifier form. The cosmetic of the present invention can be applied without particular limitation as long as it is an item that is usually applied in cosmetics. For example, basic cosmetics such as emulsions, nutritional creams, cleansing creams, massage creams, and under makeups. Suitable examples include makeup cosmetics such as foundations. A particularly preferred item is a basic cosmetic, among which a massage is more preferable, and in the massage, a cosmetic for esthetic massage treatment is particularly preferable. This is because the reversal is gentle, the change of the friction coefficient is small, and the comfort provided by the massage treatment is increased. Further, as a secondary effect, the inclusion of such a combination has a property that it can be easily removed with an aqueous carrier, and there is also a property that the cosmetic after massage can be removed by a makeup operation similar to wiping with a wet towel. The ability to remove cosmetics with this type of wiping allows the comfort of the entire esthetic course to be obtained because the cosmetic removal operation can maintain the comfort of the previously constructed treatment without interruption. There is a merit that the total amount increases. In order to further enhance such effects, it is preferable to contain 0.5 to 2% by mass of polyoxyethylene fatty acid glyceryl. As such polyoxyethylene fatty acid glyceryl, POE (7) coconut oil fatty acid glyceryl (for example, “Cethiol HE” manufactured by Cognis Japan Co., Ltd.), POE (7) (caprylic acid / capric acid) glyceryl (for example, Cognis Japan) "Cethiol 810HE", POE (20) isostearic acid monoglyceride (for example, "Emalex GWIS-120" manufactured by Nihon Emulsion Co., Ltd.), POE (20) isostearic acid triglyceride (for example, "Ema" manufactured by Nihon Emulsion Co., Ltd.) Rex GWIS-320 ") and the like can be suitably exemplified.

  Since massage involves a rubbing operation, there is also a secondary function of removing complex dirt such as fats and oils existing in the back of pores by this operation. In particular, in esthetic massage treatments, the effect of removing such composite stains is an important factor in restoring the vitality of the skin. For this reason, in order to further enhance such effects, it is preferable that the cosmetic of the present invention contains a component having a remarkable soil removing action. As such a component having a remarkable soil removal effect, for example, diglycerin tetraoleate can be preferably exemplified. The preferable content of such a component in the cosmetic of the present invention is 1 to 10% by mass, and more preferably 2 to 8% by mass. This is a content suitable for removing the composite soil.

  The cosmetic of the present invention can be produced by treating the essential components and optional components according to a conventional method.

  Hereinafter, the present invention will be described in more detail with reference to examples, but it goes without saying that the present invention is not limited to such examples.

  According to the prescription shown in the following Table 1, massage material 1 which is a cosmetic material of the present invention was prepared. That is, the ingredients of a and b were heated to 80 ° C., and b was gradually added to a while stirring, and the mixture was cooled with stirring to obtain massage material 1.

<Test Example 1>
Along with the massage material 1, a comparative example 1 in which the POE (150) distearate of the massage material 1 is replaced with water, and a comparative example 2 in which “NOMCOAT LAH” is replaced with water are prepared by the same procedure as the massage material 1, These were used in actual massage treatment, saliva was collected before and after the treatment, and the concentration of dehydroepiandrosterone (DHEA) in the saliva was measured. The increase rate of DHEA was calculated according to the formula (concentration of DHEA after treatment−concentration of DHEA before treatment) / (concentration of DHEA before treatment) × 100. The concentration of DHEA was determined by the sandwich antigen antibody method using an anti-DHEA mouse antibody and an anti-mouse rabbit labeled antibody. The massage fee was removed by wiping with a wet towel. The results are shown in Table 2. This shows that the cosmetic of the present invention is excellent in the comfort imparting effect. The number of cases used was 3 people per group.

<Test Example 2>
After the wiping operation with the wet towel of Test Example 1, after 10 minutes, weigh a 1 cm × 1 cm oil blotting paper on the nostril portion of each panel, apply it for 5 minutes, and then weigh the mass again. The mass increase rate by sticking was determined. The results are shown in Table 3. From this, it can be seen that the mass of the massage material 1 does not increase so much, but the comparative example 1 and the comparative example 2 significantly increase compared to the massage material 1. This seems to be due to the fact that the composite stains were not sufficiently removed in Comparative Examples 1 and 2 and the cosmetics and stains were not sufficiently removed by wiping with a wet towel.

  Similarly to the massage fee 1, according to the prescription in Table 4, a massage fee 2 which is a cosmetic of the present invention was prepared. When this was evaluated by the method of Test Example 1, the DHEA increase rate was 14.9 ± 4.6%, and the mass increase rate of Test Example 2 was 4.7 ± 3.9. It could be confirmed.

  Similarly to the massage fee 1, according to the prescription in Table 5, a massage fee 3 which is a cosmetic according to the present invention was prepared. When this was evaluated by the method of Test Example 1, the DHEA increase rate was 15.1 ± 2.4%, and the mass increase rate of Test Example 2 was 5.1 ± 3.4. It could be confirmed.

  Similarly to the massage fee 1, according to the prescription in Table 6, a massage fee 4 which is a cosmetic of the present invention was prepared. When this was evaluated by the method of Test Example 1, the DHEA increase rate was 12.4 ± 6.3%, and the mass increase rate of Test Example 2 was 7.2 ± 4.9. Although confirmed, it was less effective than the massage fee 1. This is probably because diglycerin tetraoleate is not contained, so that the composite soil is not sufficiently removed and the comfort is reduced.

  The present invention can be suitably applied to massage materials for esthetic treatment.
