Background
Conventionally, bottles and tubes have been generally used as containers for storing liquid cosmetics. However, since bottles and tubes are difficult to carry when going out and make up easily, in recent years, cosmetics have been developed in the form of containers such as a sponge in which a liquid cosmetic is impregnated into a powder container, and applied to the skin from the container with fingers and an applicator when in use.
However, in the water-in-oil emulsion cosmetic that is taken out from the impregnated body with a finger or an applicator and applied to the skin, it is necessary to consider the suitability for filling and the retention of the impregnated body, and therefore, it is not necessarily sufficient in terms of the feel of use and the effect of correcting pores/fine wrinkles when applied to the skin.
Therefore, it is desired to develop a water-in-oil emulsion cosmetic for impregnation which can exert excellent feel in use and correction effect of pores/fine wrinkles while maintaining suitability for filling and retention of the impregnated body.

Etc.), and the like.
The amount of the emulsifier to be blended is not particularly limited, and a plurality of kinds of the emulsifiers are used in combination, and in general, in an emulsified cosmetic product blended with 10% or more of the powder, the emulsifier is adsorbed to the powder, and therefore the amount of the emulsifier to be blended increases. If the amount of the emulsifier to be blended is increased, usability tends to be poor, but when the acrylic polymer containing a dendrimer-type siloxane is used in combination, the amount of the emulsifier to be blended can be reduced, and for example, if the amount of the emulsifier (active agent) other than the component (a) is suppressed to less than 5%, it is preferable in terms of usability.
The water-in-oil emulsion cosmetic for impregnation of the present invention can be produced by a conventional method by blending other components within a range that does not impair the effects of the present invention.
Examples of the other components include fine powder, pigment-grade powder, thickener, metal ion chain sealer, amino acid, organic amine, pH adjuster, skin nutrient, vitamin, antioxidant auxiliary, and perfume.
Examples of the thickener include gum arabic, carrageenan, karaya, tragacanth, carob gum, quince seed (quince), casein, dextrin, gelatin, sodium pectate, sodium arginine, methylcellulose, ethylcellulose, CMC, hydroxyethyl cellulose, hydroxypropyl cellulose, PVA, PVM, PVP, sodium polyacrylate, carboxyvinyl polymer, locust bean gum, guar gum, tamarind gum, dialkyldimethylammonium sulfate cellulose, xanthan gum, magnesium aluminum silicate, bentonite, hectorite, A1Mg silicate (Veegum), saponite, silicic anhydride, dextrin fatty acid ester, organically modified clay mineral, and the like. As the dextrin fatty acid ester, dextrin palmitate/2-ethylhexanoate are known. Disteardimethylammonium hectorite is preferred in terms of stability, conversely, it is known that the use becomes heavy. According to the present invention, a stable composition can be obtained without blending such a thickener.
As the usability-adjusting powder, silicone resin, silicone rubber, or the like forming a three-dimensional network structure may be blended.
The water-in-oil emulsion cosmetic for impregnation of the present invention can be applied to cosmetics, medicines and quasi-medicines widely used for skins. Examples of the application include foundations, make-up base creams, cosmetic solutions, lotions, creams, and dermatological ointments.
The water-in-oil emulsion cosmetic for impregnation of the present invention is impregnated into the impregnated body and then stored in a powder box container having air tightness, whereby a container form suitable for carrying can be formed.
Examples
The present invention will be described in further detail with reference to examples, but the present invention is not limited to these examples. The numerical values in the table indicating the amounts to be blended represent mass% in the total amount of the cosmetic. In the case of using a commercially available raw material product, the blending amount of an actual component (solid component) other than a solvent or the like is shown.
For the crosslinked polyether-modified silicone described in Table 1, KSG-210, made by (polydimethylsiloxane/(PEG-10/15)) crosslinking polymer 20-30 mass% and polydimethylsiloxane 70-80 mass%, was used, and for the acrylic polymer containing dendritic macromolecular siloxane, dow, made by polymer 30 mass% and decamethylpentasiloxane 70 mass%, was usedFA4001CM Silicone Acrylate or Dow +.formed from 40% by mass of polymer and 60% by mass of isododecane>FA4002CM Silicone Acrylate for trimethylsilyloxy silicate, SSD-R3 made of trimethylsilyloxy silicate 50% by mass and decamethyl cyclopentasiloxane 50% by mass was used and blended so as to be the actual component amounts in the table, respectively.
The "wettability", "presence or absence of tackiness", and "pore correction effect" as evaluation items were evaluated by the functional test based on 10 panelists, respectively, in the case of application with a finger and in the case of application with a puff. As the impregnated body, a fiber body molded from a polyester fiber (hardness 40 to 60 (measured by F durometer) and density 0.018g/cm were used 3 )。
TABLE 1
Evaluation of the samples: the method is marked as @: very excellent (pass), ≡o: excellent (pass), delta: difference (reject), ×: very bad (unacceptable).
As shown in table 1, in examples 1 to 8, good results were obtained for all evaluation items.
In general, fine-grained titanium oxide is blended in foundations and the like in order to impart SPF. For example, if 3 mass% or more of fine titanium oxide is blended, the friction feeling and the powder tend to be easily felt, and the misalignment after 3 hours and the evaluation of the powder tend to be poor, but in the water-in-oil type emulsion cosmetic for impregnation of the present invention, it was confirmed that good results can be obtained in all evaluation items in the case of blending fine titanium oxide.
The viscosities of examples 1 to 8 were about 4000 to 28000mpa·s as measured at a temperature of 30 ℃ using a B-type rotary viscometer, and it was confirmed that the impregnation and the filling of the impregnated body could be easily performed, and the impregnated body remained stable for a long period of time after the impregnation. If the viscosity is lower than 4000mpa·s, the sense of fit is insufficient, and the pore correction effect is not easily obtained, and if the viscosity exceeds 28000mpa·s, the positional shift with time is easily generated. When the ratio of the nonvolatile oil to the total oil content is preferably 15 to 60%, less than 15% or more than 60%, the effect of the present invention is not easily obtained.
The following shows a formulation example of the water-in-oil emulsion cosmetic for impregnation according to the present invention. The unit of the blending amount is defined as mass%. In the case of using a commercially available raw material product, the blending amount of an actual component (solid component) other than a solvent or the like is shown.
The crosslinked polyglycerin-modified silicone as component (A) was blended with the polydimethylsiloxane/(polydimethylsiloxane/polyglycerin-3) crosslinked polymer for formulation examples 1 and 2, and the crosslinked polyether-modified silicone as component (A) (polydimethylsiloxane/(PEG-10/15)) was blended with the (polydimethylsiloxane/(PEG-10/15)) crosslinked polymer for formulation examples 3 and 4.
Any of the cosmetics shown in the formulation examples is excellent in feel in use, pore-correcting effect and storage stability, and can be used for various cosmetic products.
