Description

Technical Field

[0001] The present invention relates to a water-in-oil emulsified solid cosmetic, and more specifically, it has a smooth spread and a high emollient feel, is excellent in a fresh feel, quickly forms a uniform cosmetic film without stickiness, and relates to a water-in-oil emulsified solid cosmetic excellent in makeup retention, production stability, and stability over time.

Background Art

[0002] Conventionally, in makeup cosmetics such as foundation and blush, there has been a preference for water-in-oil emulsified cosmetics that have a smooth spread and gloss like an oil-based cosmetic with a high oil content, a high emollient feel, a fresh feel like an aqueous cosmetic, and a powdery texture that does not feel sticky after application, and various studies have been conducted. In recent years, among them, solid cosmetics have been preferred due to their ease of use and portability. In particular, stick-shaped cosmetics that can be miniaturized are convenient for carrying. Therefore, cosmetics that solidify water-in-oil emulsified cosmetics have been studied. For example, the development of stick-shaped cosmetics that can be used for moisturizing the skin as in Patent Document 1, and the development of cosmetics with improved texture and moldability (for example, Patent Documents 2 and 3) have been studied.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the water-in-oil emulsion solid cosmetic, since the outer layer is an oily component, if the spreading is too good, the cosmetic film will thinly spread and it has been difficult to easily form a uniform cosmetic film just by lightly stretching on the skin. In particular, in the technology of replenishing skin moisture using a silicone elastomer as in Patent Document 1, since the spreading becomes high by containing the silicone elastomer, the adhesiveness is low and it is difficult to easily form a uniform cosmetic film unless it is firmly stretched with a finger. Depending on the content, there is a tendency to be easily broken during application. Further, for example, in the technology of Patent Document 2, although it has a fresh feeling because it does not contain volatile components other than water, there are many oil agents remaining after finishing, and it tends to form a sticky cosmetic film and has a tendency not to be excellent in makeup durability. Further, for example, in the technology of the solid water-in-oil cosmetic of Patent Document 3, although it has features such as non-uniformity of oil components, suppression of water evaporation, excellent filling moldability and stability over time, good cooling sensation, moist feeling, and makeup durability after application, since the size of the wax crystals during solidification cannot be made uniform, it is necessary to stretch well with a finger or a tool when forming a cosmetic film, and there may be a problem in the effect of quickly and easily forming a uniform cosmetic film. Further, when filling and molding, there may be a problem in manufacturing stability that there is a variation between what solidifies and what does not solidify, and it is necessary to increase the amount of surfactant and solid oil, and there may be a case where stickiness and smooth spreading are not sufficient. That is, in the water-in-oil emulsion solid cosmetic with a high content of oily components, it is an object to provide a water-in-oil emulsion solid cosmetic that has a smooth spreading, a high emollient feeling in use, a fresh feeling in use, does not feel sticky after finishing, can quickly form a uniform cosmetic film, and is excellent in manufacturing stability. Further, it is an object to provide a water-in-oil emulsion solid cosmetic that is also excellent in stability over time and can continue this effect until it is used up.

Modes for Carrying Out the Invention

[0008] Hereinafter, the present invention will be described in detail. In the present specification, “%” represents mass% unless otherwise specified, and when a numerical range is represented using “~”, the range includes the numerical values at both ends. The average particle diameter of the powder in the present invention is the median diameter (D50) of the major axis by the image analysis method using an electron microscope. The present invention is not limited to the following preferred embodiments and can be freely changed within the scope of the present invention.

[0009] The polypropylene polymer of component (A) used in the present invention is a solid oil having an amorphous branched structure obtained by polymerizing propylene. When formulated in cosmetics, it has little crystal growth over time, improves the storage stability so that it can be stably formulated in oils, and has excellent adhesion to the skin, thus having the effect of uniformly adhering powder to the skin. Therefore, by containing it together with hydrophobized powder, the uniformity of the cosmetic film can be improved. Further, it penetrates into the wax crystals of component (B) in the oil system, suppresses the extreme crystal growth of component (B), homogenizes the card house structure, and reduces the variation in filling moldability when melting and solidifying as a solid cosmetic, and is used for the purpose of imparting storage stability that reduces the strength change due to temperature change over time and maintains the same usability until the end. Also, the wax crystals homogenized with component (B) quickly form a smooth spreading and a uniform cosmetic film due to adhesion. It preferably has the physical properties shown below because of the above characteristics.

[0010] The weight average molecular weight (hereinafter simply referred to as Mw) of the polypropylene polymer of component (A) in the present invention is 25,000 to 100,000, more preferably 25,000 to 40,000. If Mw is less than 25,000, stickiness may occur, and if it exceeds 100,000, it may be inferior in soft usability.

[0011] Also, the polypropylene polymer of component (A) used in the present invention preferably has a molecular weight distribution (Mw / Mn) measured by the GPC method of 4 or less, more preferably 3.5 or less, and particularly preferably 3.0 or less. If the molecular weight distribution (Mw / Mn) exceeds 4, stickiness may occur.

[0012] The melting point of the polypropylene polymer of component (A) used in the present invention is preferably 60°C to 100°C, more preferably 70°C to 90°C. The melting point is measured using a differential scanning calorimeter (DSC). After holding the sample at -10°C for 5 minutes in a nitrogen atmosphere, the melting point (Tm) is defined as the peak top of the melting endothermic curve observed on the highest temperature side obtained by heating at a rate of 10°C / min.

[0013] The polymerization method of the polypropylene polymer of component (A) used in the present invention is not particularly limited, and any method such as slurry polymerization method, gas phase polymerization method, bulk polymerization method, solution polymerization method, suspension polymerization method, etc. may be used.

As the volatile silicone oil, those having a boiling point of less than 200°C are preferable in terms of drying rate. For example, methyltrimethicone and dimethicone are preferably used.

[0024] The content of component (D) in the present invention is not particularly limited, but as the lower limit, it is preferably 2.0% or more, more preferably 5.0% or more, and as the upper limit, it is preferably 40% or less, more preferably 25% or less, and still more preferably 15% or less. Within this range, the spreading is good, a fresh feeling can be obtained during application, there is no stickiness, and it is more preferable in terms of excellent makeup sustainability and production stability.

In addition, due to the molecular structure of component (D), components (B) and (C) that are easy to maintain their shape can be appropriately adjusted. The contents of components (B) and (C) are also appropriately adjusted according to the mass ratio to component (E).

[0026] Component (E) in the present invention is not limited to purified water, and may be water extracted from nature, such as water obtained by steam distillation of plants. The pH, salts, and other impurity contents at that time are not particularly limited. The content of component (E) is preferably 15% or more, more preferably 20% or more as the lower limit, and preferably 60% or less, more preferably 50% or less, still more preferably 40% or less as the upper limit. Within this range, it is more preferable in terms of obtaining freshness during application, having no stickiness, and excellent makeup persistence.

[0027] The hydrophobic treated colored powder of component (F) in the present invention has the effects of improving the makeup persistence such as water resistance, sweat resistance, and sebum resistance of the water-in-oil type emulsified solid cosmetic, and the compatibility with component (A). The colored powder of component (F) is not particularly limited in terms of material and size, but is not particularly limited as long as it is a powder that reflects in the visible light region. Preferably, the average particle diameter (D50) is in the range of 0.1 to 2.0 μm. Specifically, metal oxides, pigments, etc. are preferable, and examples include titanium oxide, zinc oxide, iron oxide, aluminum oxide, barium sulfate, anhydrous silicic acid, polymethylsilsesquioxane powder, mica, sericite, manganese violet, carmine, tar pigment, cellulose powder, and one or more of them may be used in combination.

[0028] The hydrophobic treatment agent for component (F) in the present invention is not particularly limited as long as it imparts lipophilicity, and the surface treatment method is also not particularly limited. Specifically, for example, methods of treating the powder surface with metal soaps, triethoxycaprylylsilane, silicone, fatty acids, acylated amino acids, isopropyl titanate triisostearate, phospholipids, dextrin fatty acid esters, polyethylene oxide, and fluorine compounds having a perfluoroalkyl group are mentioned, and one or more of them may be used in combination. In particular, those containing a hydrophobic group having 14 or more carbon atoms, such as metal soaps, fatty acids, acylated amino acids, phospholipids, dextrin fatty acid esters, and polyethylene oxide, are more preferable because they have excellent adhesion to the skin and improve the uniformity of the makeup film.

[0029] In addition, when the refractive index difference between the component (F) and the component for dispersing it in the cosmetic is high, it is preferable because it has a more coloring effect, and it may be dispersed in the outer layer oil agent or the inner layer aqueous component.

[0030] In the present invention, the content of the component (F) is, as a lower limit, preferably 1% or more, more preferably 3% or more, still more preferably 5% or more, and as an upper limit, preferably 25% or less, more preferably 20% or less, still more preferably 15% or less.

[0031] In the present invention, the component (F) may be further adhered to or complexed with the surface of the spherical powder of the component (G). The component (G) in the present invention means that the shape is spherical, but the ratio of the major axis to the minor axis may be in the range of 1 to 2, and the surface state is not particularly limited, and there may be irregularities of 1 / 7 or less of the average particle diameter. The material is not particularly limited, but in the case of inorganic powder, for example, anhydrous silicic acid is preferable, and in the case of organic powder, one or more selected from synthetic resin powders such as nylon powder, methylsiloxane network polymer, crosslinked dimethylpolysiloxane powder, acrylic resin powder and polyethylene powder, cellulose, starch, silk, dextrin and other natural powders are used. When the component (F) in the present invention is adhered to the surface of the component (G), the colored powder of the component (F) in the present invention does not directly adhere to the skin surface, so a coating film is formed without following the irregularities of the skin surface such as texture and pores, resulting in a uniform cosmetic film. In addition, since the average particle diameter of the component (F) is relatively small, it has the effect of improving the spreading and dispersibility of the component (F).

[0032] The method for adhering the component (F) in the present invention to the surface of the component (G) is not particularly limited, but for example, there are a mechanochemical method of applying forces such as mixing and grinding to contact and adhere them, and a method of depositing (F) on the surface of (G) in a solvent.

[0033] Component (H) in the present invention is one or more selected from hydroxystearic acid esters and phytosterol esters. By dissolving together with component (C), it stabilizes the crystals of the wax of component (C) in the oil system over time. Also, since it has water-holding capacity, it imparts the effect of excellent stability over time and production stability. Specifically, as the skeleton having a hydroxyl group, one or more ester oils selected from dipentaerythritol skeleton, phytosterol skeleton, and trimethylolpropane skeleton are preferable. In particular, dipentaerythritol ester and phytosterol ester are more preferable.

[0057] As is clear from the results of Tables 1 and 2, the stick-shaped foundations of Examples 1 to 18, which are the products of the present invention, are foundations excellent in all items of "freshness", "smooth spreadability", "emollient feeling", "non-greasiness", "uniformity of makeup film", "makeup durability", "stability over time", and "manufacturing stability". On the other hand, in Comparative Example 1 which does not contain component (A), there was no "smooth spreadability" and "uniformity of makeup film", and it was inferior in "stability over time". Further, in Comparative Example 2 which does not contain component (B), there was no "non-greasiness", "uniformity of makeup film", and "emollient feeling", and it was inferior in "stability over time" and {manufacturing stability}. Also, Comparative Example 3 which does not contain component (C) had low "smooth spreadability" and "emollient feeling", no "uniformity of makeup film", and was inferior in "makeup durability", and "stability over time" and "manufacturing stability" were also not favorable. Further, in Comparative Example 4 where there is a large amount of component (E) and no component (D), although "freshness" and "non-greasiness" are excellent, there is no "smooth spreadability" and "emollient feeling", it is inferior in "stability over time", tends to sweat after 1 day and collapse during use, and "manufacturing stability" is very poor. Although it is fresh at the initial stage of filling, it could not maintain the same quality over time. Comparative Examples 5 and 6 in which component (E) is not blended or is in a small amount tended to be inferior in "freshness", "uniformity of makeup film", "non-greasiness", and "makeup durability". Further, in Comparative Example 7 which does not contain a hydrophobically treated colored powder, although it is excellent in "freshness" and "emollient feeling", due to the non-hydrophobic surface, the dispersibility of the powder is poor, there is no "smooth spreadability" and "uniformity of makeup film", and wrinkles at the outer corners of the eyes and sagging of the sebaceous glands are seen after 1 hour from makeup application, and it is inferior in "makeup durability", and is inferior in "stability over time", especially in "manufacturing stability" when the heating state continues. Furthermore, Comparative Example 8 in which there is a large amount of component (D) had no "uniformity of makeup film" and was inferior in "freshness" and "manufacturing stability".
