Description

Technical Field

[0001] The present invention relates to solid powder cosmetics. Background Art

[0002] Solid powder cosmetics are cosmetics that are formed by adding and mixing a cosmetic base with an oily component into a powder component and filling it in a container such as a tray. They are easy to use and portable, so they are popular with consumers. In recent years, in particular, the texture when applied to the skin is required to be matte, with gloss suppressed and fine skin texture.

[0003] Usually, in order to achieve a matte effect, the amount of powder and the curing agent used to bond the powders is increased. However, if a large amount of powder is added, the friction feeling brought to the skin becomes stronger, and sometimes it is easy to feel dry. In response to this problem, by increasing the amount of oily components used to moisturize the skin, the glossiness will become stronger, and sometimes it is difficult to obtain the required matte feeling. In addition, if a large amount of curing agent is added, the ductility during application will be reduced, and the removability (adhesion) of the cosmetics (the adhesion of the cosmetics to the application tools, fingers, etc. is good and appropriate) will be reduced. Therefore, in order to take into account both the makeup effect with a matte feeling and the usability, various studies have been conducted so far. For example, a color cosmetic is proposed, which contains a silicone gel containing a cross-linked polyether modified silicone and a silicone oil, an oil component, and a powder. The color cosmetic has good color development, excellent makeup lasting, and good removability (for example, refer to Patent Document 1).

[0004] In addition, a cosmetic has been proposed, which achieves a makeup effect of a matte coating film with suppressed gloss and reduced dryness by combining specific amounts of two or more powders of different shapes, an elastomer, a specific amount of a non-volatile oil component, and a specific amount of wax (for example, see Patent Document 2); and a solid cosmetic has been proposed, which achieves a matte makeup effect and excellent spreadability when applied by combining specific amounts of (a) one or more powders selected from fumed silica and particulate titanium dioxide, (b) wax, (c) a cross-linked organopolysiloxane, (d) a powder other than component (a), and (e) a non-volatile low-viscosity oil component, respectively (for example, see Patent Document 3).

[0010] The technology of Patent Document 1 is excellent in terms of good removal, but the glossiness is strong and there is room for improvement in terms of matte feeling. In addition, the technologies of Patent Documents 2 and 3 are excellent in terms of good makeup effect with matte feeling with suppressed gloss and good spreading, but the cosmetics become hard due to the addition of wax as solid fat, and satisfactory good removal cannot be obtained. Furthermore, when applying solid powder cosmetics, astringency (dryness) may be felt, and there is room for improvement in this regard.

[0011] In view of the above-mentioned actual situation, the inventors conducted intensive research and found a solid powder cosmetic which combines a specific amount of a cross-linked organopolysiloxane polymer having an alkyl branch or a phenyl branch on the main chain, one or more plate-like powders selected from mica, synthetic fluorphlogopite, and boron nitride with an average particle size of 5 to 20 μm, an oily agent in a paste form at 25°C, and an ester oil with an IOB value of 0.15 to 0.50 and a viscosity of 10 to 10000 mPa·s at 20°C, suppresses the amount of wax incorporated, achieves a matte makeup effect, and has good usability (good cosmetic removal, good spreading during application, and no dry feeling), thereby completing the present invention.

In this way, the mass ratio of component (C) relative to the total amount of non-silicone oil and the mass ratio of component (D) relative to the total amount of non-silicone oil can be adjusted. The content of hydrocarbon oil and / or ester oil other than component (C) and component (D) in the cosmetic is, for example, 1 to 10% by mass, and can be 1 to 8% by mass.

[0065] (Component (D): ester oil having an IOB value of 0.15 to 0.50 and a viscosity of 10 to 10000 mPa·s at 20° C.)

[0066] The component (D) used in the present invention is an ester oil having an IOB value of 0.15 to 0.50 and a viscosity of 10 to 10,000 mPa·s at 20°C. Component (D) can also be considered to be a liquid ester oil having an IOB value of 0.15 to 0.50. If the IOB value of component (D) is less than 0.15, the dry feeling is significantly deteriorated. In addition, if the IOB value of component (D) exceeds 0.50, the ductility during application is significantly deteriorated. The detailed mechanism is not clear, but it is believed that by making the IOB value within the above range, the hydrophilicity becomes moderate, and the effect of the present invention is exerted through interaction with other components. If the viscosity of component (D) is less than 10 mPa·s, the ductility during application is significantly deteriorated. If the viscosity of component (D) exceeds 10,000 mPa·s, the ductility during application and the removability of cosmetics are significantly deteriorated.

[0067] The component (D) used in the present invention is not particularly limited as long as it has an IOB value of 0.15 to 0.50 and a viscosity of 10 to 10000 mPa·s at 20° C. Specifically, there can be mentioned isotridecyl isononanoate (IOB=0.16, viscosity=11 mPs·s), polyglyceryl-2 tetraisostearate (IOB=0.17, viscosity=369 mPs·s), neopentyl glycol dicaprate (IOB=0.25, viscosity=19 mPs·s), and polyisostearate (IOB=0.16, viscosity=11 mPs·s). s), diisostearyl malate (IOB = 0.28, viscosity = 5500mPs·s), neopentyl glycol di(ethylhexanoate) (IOB = 0.32, viscosity = 14mPs·s), pentaerythritol tetra(ethylhexanoate) (IOB = 0.35, viscosity = 124mPs·s), tri(ethylhexanoin) (IOB = 0.36, viscosity = 30mPs·s), etc., and one or more of them can be appropriately selected and used. Among them, from the perspective of the effects of the present invention, component (D) is preferably at least one selected from the group consisting of polyglyceryl-2 tetraisostearate, diisostearyl malate, pentaerythritol tetra(ethylhexanoate) and glyceryl tri(ethylhexanoate). When at least one selected from the group consisting of polyglyceryl-2 tetraisostearate, diisostearyl malate and pentaerythritol tetra(ethylhexanoate) is selected, it is more preferred because it is excellent in terms of good spreading during application, impact resistance, etc., and diisostearyl malate is further preferred.

[0068] The IOB value is an index that indicates the polarity of an organic compound in terms of the balance between inorganic and organic properties and is expressed as IOB value = inorganic value / organic value. A compound with a larger value is considered to be more hydrophilic.

[0069] It should be noted that, when an ester oil having an IOB value of 0.15 to 0.50 and a viscosity of 10 to 10,000 mPa·s at 20°C is used as an oil agent for swelling component (A), the oil agent is not considered as component (D). Similarly, when an ester oil having an IOB value of 0.15 to 0.50 and a viscosity of 10 to 10,000 mPa·s at 20°C is used as a surface treatment agent for a powder, the oil agent is not considered as component (D). That is, component (D) is an ester oil having an IOB value of 0.15 to 0.50 and a viscosity of 10 to 10,000 mPa·s at 20°C as a formulation component. The same applies to component (C).

[0070] The viscosity of component (D) used in the present invention is a value measured using a Brookfield viscometer. Examples of Brookfield viscometers include single-cylinder rotational viscometers Vismetron (registered trademark) (manufactured by Shibaura Systems, Inc.). The measurement method is as follows: fill the measurement sample into a glass bottle having an outer diameter of 45 mm, an inner diameter of 38 mm, and a height of 82 mm in a manner that does not produce an air gap, cover it with a lid, and place it in a 20°C constant temperature bath for a day and night. The next day, use a single-cylinder rotational viscometer Vismetron (registered trademark) (manufactured by Shibaura Systems, Inc.), use the attached rotors 1 to 4, read the measured value after 1 minute at a rotation speed of 6 to 30, and multiply by each multiplier to obtain the viscosity value.

[0071] Examples of commercially available products of the component (D) used in the present invention include COSMOL 44V (manufactured by Nisshin OilliO Group, Ltd.) which is polyglyceryl-2 tetraisostearate, COSMOL 222 (manufactured by Nisshin OilliO Group, Ltd.) which is diisostearyl malate, and SALACOS 5408 (manufactured by Nisshin OilliO Group, Ltd.) which is pentaerythritol tetra(ethylhexanoate).

[0074] The content of component (D) used in the present invention relative to the total amount of non-silicone oil is 5% to 45%. If the content of component (D) relative to the total amount of non-silicone oil exceeds 45%, the matte feeling is significantly reduced. In addition, if the content of component (D) relative to the total amount of non-silicone oil is less than 5%, the dry feeling is significantly reduced. From the viewpoints of impact resistance and ductility during application, the content of component (D) relative to the total amount of non-silicone oil can be 6% or more, 7% or more, 8% or more, 9% or more, or 10% or more as a lower limit, and preferably 40% or less, more preferably 35% or less, further preferably 30% or less, further preferably 25% or less, particularly preferably 20% or less, and most preferably 15% or less.

[0206] On the other hand, Comparative Example 1, which does not contain component (A), has a strong dry feeling and cannot obtain satisfactory results in matte feeling. Comparative Example 2, which does not contain component (B), cannot obtain satisfactory results in ductility and matte feeling when applied. Comparative Example 3, which does not contain component (C), has poor impact resistance, which makes it easy to produce cracks and cracks when the sample falls, and cannot obtain satisfactory results in matte feeling and non-dry feeling. Comparative Example 4, which does not contain component (D), easily produces dry feeling and poor ductility. In Comparative Example 5, in which the content of component (C) exceeds 50% relative to the total amount of non-silicone oil, the cosmetics have poor removability and cannot obtain satisfactory results in ductility when applied. In Comparative Example 6, in which the content of component (D) exceeds 45% relative to the total amount of non-silicone oil, the matte feeling is poor and cannot obtain satisfactory results in good ductility. In Comparative Example 7, in which the content of component (E) exceeds 3%, the cosmetics are difficult to remove and cannot obtain satisfactory results in ductility.
