Description

The present invention relates to a cleansing cosmetic composition, more particularly to cleansing cosmetic composition is emulsion of the oil / D phase form.

  Cleansing cosmetics are, for example, cosmetics that are difficult to remove by normal aqueous cleaning, such as lip colors, and cosmetics used for the purpose of removing greasy stains, and currently known dosage forms include surfactants Makeup remover cosmetics that are aqueous carrier solutions of the above, cleansing cosmetics of the high internal phase oil-in-water emulsion type, cleansing cosmetics of the non-water emulsifier type, and the like.

  In any of these dosage forms, a hydrophilic surfactant is used for the purpose of adapting the oil component to the aqueous component, and polyoxyethylene is added as the hydrophilic surfactant. Usually, nonionic surfactants are used. Furthermore, in the above-mentioned dosage form, water exists and an environment in which microorganisms are easy to propagate. Therefore, a preservative such as paraben is usually used for the purpose of preventing microbial contamination.

  In recent years, reflecting the stressful social environment, an increasing number of people are sensitive to chemical substances, and they are sensitive to polyoxyethylene-added nonionic surfactants and preservatives such as parabens. Many people present. Moreover, it can be said that in a cleansing cosmetic that requires a rubbing operation using a cosmetic for use, an environment in which such sensitive people exhibit a hypersensitive pore reaction is prepared. In other words, in cleansing cosmetics, it can be said that there is a demand for the development of cleansing cosmetics with extremely low irritation that can be used by such sensitive people.

Moreover, the cosmetic for conventional cleansing, for example, as oil gel preparations, such as lip color, have been designed with the aim of lowering the hard dirt off the cleaning agent aqueous, In recent years, It is difficult to remove with conventional cleansing materials, such as makeup cosmetics containing a core-shell type acrylic resin emulsion, which have significantly improved makeup retention, and for cleansing to remove such cosmetics. The development of cosmetics was desired.

As a means of suppressing the stimulation of the cosmetics for cleansing, the content of the surfactant is reduced, and the damaged dirt removal effect is supplemented by using a disintegrating powder composition as a rubbing medium. Although the method of using etc. is devised ( for example, refer to patent documents 1 ), since surfactant exists even if it is a small quantity, it is said that safety improved remarkably compared with the conventional cleansing cosmetics. Nonetheless, irritation from surfactants has not been completely overcome.

On the other hand, techniques for incorporating powders into cleansing cosmetics are already known ( see, for example, Patent Document 2, Patent Document 3, and Patent Document 4 ). It was used for the purpose of making it safe, and was not performed from the viewpoint of improving safety, and the level of safety was the conventional level.

In addition, in the D phase (surfactant phase) formed with polyhydric alcohol, surfactant and a small amount of water, the interface is very active, and an emulsification method or a drug dispersion method using it has been developed. ( For example, Patent Literature 5, Patent Literature 6, Patent Literature 7, Patent Literature 8, Patent Literature 9 ). However, an example in which an emulsion in the form of an oil / D phase, in which the D phase is a continuous phase and the oil phase is an emulsified droplet, is applied to cleansing cosmetics using the D phase is not yet known.

Furthermore, cleansing cosmetics comprising an emulsion containing 1) 5 to 10% by weight of water, 2) 5 to 12% by weight of a specific nonionic surfactant, and 2) 60 to 80% by weight of oil are not known. Also, it is not known that the emulsion form of such an emulsion is an oil / D phase form.

JP 2002-202333 A JP 2002-302421 A JP 2001-106858 A Japanese Patent Laid-Open No. 08-143420 Japanese Patent Laid-Open No. 06-279254 Special table 2003-511235 gazette JP-T-2001-510150 JP 58-106532 A Japanese translation of PCT publication No. 03-502661

  The present invention has been made under such circumstances. In the process of use, the present invention has a makeup with an extremely low stimulus expression and an improved makeup that is difficult to remove with conventional cleansing cosmetics. It is an object of the present invention to provide a cleansing cosmetic that is excellent in the action of dropping up cosmetics.

In view of such a situation, in the process of use, irritation is extremely low, and it is excellent in the action of removing make-up cosmetics with improved makeup lasting that was difficult to remove with conventional cleansing cosmetics. As a result of earnest research efforts in search of cosmetics for cleansing, 1) 5 to 10% by weight of water and 2) 5 to 12% by weight of specific nonionic surfactant and 2) 60 to 80% by weight of oil It was found that a cleansing cosmetic comprising an emulsion in the form of an oil / D phase has such characteristics, and has completed the invention .

That is, this invention relates to the technique shown below.

(1) 1) 5 to 10% by weight of water, 2) 5 to 12% by weight of a nonionic surfactant containing polyoxypropylene polyoxyethylene alkyl ether, polyoxyethylene fatty acid glyceryl and polyoxyethylene alkenyl ether, 3) A cleansing cosmetic comprising 60 to 80% by mass of an oil and being an oil / D phase emulsion.

( 2 ) The cleansing cosmetic according to (1) , further comprising mica.

( 3 ) Cleansing cosmetic according to ( 2 ), characterized in that it contains aluminum fluoromagnesium potassium silicate as mica.

  According to the present invention, in the process of use, cleansing is extremely effective in removing makeup makeup that has extremely low irritation and that has improved makeup retention that is difficult to remove with conventional cleansing cosmetics. Cosmetics can be provided.

The cleansing cosmetic composition of the present invention comprises 1) 5 to 10% by weight of water, more preferably 6 to 9% by weight, and 2) polyoxypropylene polyoxyethylene alkyl ether, polyoxyethylene fatty acid glyceryl and polyoxyethylene alkenyl ether . non-ionic surfactants 5-12% by weight containing, more preferably a 8-11 wt%, 3) oil 60-80 wt%, and more preferably a 65 to 75 mass%, the oil / D phase morphology The emulsion is in the form of a cloudy appearance. The reason for exhibiting such a cloudy form is that the emulsified form is an oil / D phase form.

That is, if it is a water-in-oil emulsified form or an oil-in-water emulsified form, it takes the form of a white cream or emulsion and no transparency is observed, but in the oil / D phase emulsified form, it is slightly transparent to the emulsion Shows a cloudy form.

In order to form such an emulsified form, water, a nonionic surfactant and a polyhydric alcohol are mixed and heated to 70 to 90 ° C. to form a D phase (surfactant phase). The oil phase containing the oil adjusted to the same temperature can be formed by gradually adding with stirring. By performing such an operation, an oil / D-phase emulsified emulsion can be obtained as long as the blending conditions are satisfied.

<Example 1>
The cleansing cosmetic composition of the present invention was prepared according to the formulation shown below. That is, the components of a and b were each heated to 80 ° C., and b was gradually added to the mixture under stirring and emulsified to obtain the cleansing cosmetic 1 of the present invention. Similarly subtracting the non-ionic surfactant amount of 4.5 wt%, usually in Comparative Example 1 was adjusted to oil-in-water emulsified form (white cream), clear aqueous emulsion obtained by substituting water in 1,3-butanediol A gel comparative example 2 and a conventional cleansing oil-in-water emulsified comparative example 3 were also prepared, and the cleansing action was compared.

  The comparison of the cleansing action was performed by measuring the 2 cm × 4 cm portion of the inner side of the lower arm using the evaluation foundation shown below, then applying makeup and applying the cleansing cosmetic. Thereafter, it was rinsed with running water and measured again, and the color difference (ΔE) before make-up and after cleansing was measured. The results are shown in Table 1. From this, it can be seen that the cleansing cosmetic of the present invention has an excellent cleansing action.
