Description

[Technical field]

[0001] The present invention relates to a cosmetic that can be used as a skin cosmetic or a make-up cosmetic. Background technology

[0002] In recent years, the demand for cosmetics has become ever more diverse, and in response to this, the product forms have also become more diverse, not only in terms of item composition such as foundation, makeup base, sunscreen, lipstick, nail polish, and face powder, but also by further subdividing these, the form elements have been added such as liquid, powder, solid, emulsion, etc.

[0003] In particular, recent cosmetic products are required to have various physical and chemical properties, such as better water resistance and sweat resistance (sebum resistance) than ever before, as well as good usability when applied and abrasion resistance.

[0004] To satisfy the above requirements, the following have been proposed as technologies using silicone resins with film-forming ability: skin cosmetics as disclosed in JP-A-61-158910, additives for make-up cosmetics as disclosed in JP-A-02-42008, cosmetics as disclosed in JP-A-04-312511, and cosmetics as disclosed in WO2009 / 136486.

[0005] Furthermore, Japanese Patent Application Laid-Open No. 9-12431 proposes an invention for a cosmetic material containing a fluorine-containing silicone resin which is excellent in water resistance and sweat resistance and provides a soft coating. Summary of the Invention

[0006] The present invention aims to provide a cosmetic preparation which spreads well, is not sticky, gives a soft film and is excellent in feel when used.

[0007] The present invention provides a cosmetic preparation containing the following components (A) and (B): (A) one or more selected from 1,1,1,3,5,5,5-heptamethyl-3-alkyl(C10-14)trisiloxane (B) Average unit formula RaSiO (4-a) / 2(wherein R represents a monovalent substituted or unsubstituted hydrocarbon group, and a is a number of 1.2 to 2), Cone Resin

[0008] The cosmetic composition of the present invention spreads well and has a soft feel when applied to the skin, and is useful for preventing makeup from coming off due to sweat, etc. Furthermore, the cosmetic composition of the present invention has good usability properties such that it is not easily washed off even by washing with water, and has good stability over time. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Component (A) is one or more selected from 1,1,1,3,5,5,5-heptamethyl-3-alkyl (C10-14) trisiloxanes, which may be in an oil form at room temperature.

[0010] Non-limiting examples of component (A) include (A-1) 1,1,1,3,5,5,5-heptamethyl-3-decyltrisiloxane, (A-2) 1,1,1,3,5,5,5-heptamethyl-3-dodecyltrisiloxane, and (A-3) 1,1,1,3,5,5,5-heptamethyl-3-tetradecyltrisiloxane. Each of the components (A-1), (A-2), and (A-3) can be used alone as component (A), but when component (A) is used as the sole component, it is preferable to use component (A-2).

[0011] As the component (A), a mixture of the components (A-1) and (A-2), a mixture of the components (A-1) and (A-3), a mixture of the components (A-2) and (A-3), or a mixture of the components (A-1), (A-2), and (A-3) can be used.

[0012] When component (A) is used as a mixture of components (A-1) and (A-2) or components (A-2) and (A-3), the content of component (A-2) in 100% by mass of the mixture is preferably 50% by mass or more, more preferably 60% by mass or more, and even more preferably 70% by mass or more.

[0013] When the (A) component is used as a mixture of the (A-1) component and the (A-3) component, the (A-1) component is preferably 20 to 80 mass%, more preferably 30 to 70 mass%, and even more preferably 40 to 60 mass%, based on 100 mass% of the total amount of the (A-1) and (A-3) components. In this case, the (A-3) component is preferably 80 to 20 mass%, more preferably 70 to 30 mass%, and even more preferably 60 to 40 mass%.

[0014] When the (A) component is used as a mixture of the (A-1), (A-2) and (A-3) components, the (A-1) component is preferably 5 to 80% by mass, more preferably 10 to 70% by mass, and even more preferably 20 to 60% by mass, out of a total of 100% by mass of the (A-1), (A-2) and (A-3) components. In this case, the (A-2) component is preferably 10 to 70% by mass, more preferably 20 to 60% by mass, and even more preferably 20 to 50% by mass. In this case, the (A-3) component is preferably 10 to 70% by mass, more preferably 20 to 60% by mass, and even more preferably 20 to 50% by mass.

[0015] The silicone resin of component (B) has the average unit formula RaSiO (4-a) / 2 (In the formula, R represents the same or different monovalent substituted or unsubstituted hydrocarbon group, and a is a number of 1.2 to 2.) and has a thermal softening point of 50°C or higher.

[0016] The monovalent substituted or unsubstituted hydrocarbon group of R in the above structural unit can be, for example, one having 1 to 12 carbon atoms, particularly 1 to 8 carbon atoms, excluding the substituent. Non-limiting examples of the substituted or unsubstituted monovalent hydrocarbon group of R include alkyl groups such as methyl, ethyl, propyl, and butyl; alkenyl groups such as vinyl and allyl; aryl groups such as phenyl and tolyl; cycloalkyl groups such as cyclohexyl and cyclooctyl; or groups in which the hydrogen atom bonded to the carbon atom of these groups is substituted with a halogen atom, a cyano group, an amino group, or the like, a cyanomethyl group, a γ-aminopropyl group, and an N-(β-aminoethyl)-γ-aminopropyl group. In view of ease of synthesis and water repellency, a methyl group, an ethyl group, and a phenyl group are preferred.

[0017] In the above average unit formula, if a is less than 1.2, the film formed on the skin after application becomes hard. When used as a cosmetic, this tends to affect the feel of the coating, such as tension or stickiness. On the other hand, when a exceeds 2 in the above average unit formula, the coating tends to become viscous, which may affect the feel of the coating, such as stickiness or greasiness. In either case, it is difficult to obtain sufficient coating durability.

[0018] Specifically, the silicone resin of component (B) is R 3 SiO 1 / 2 Units, R 2 SiO 2 / 2 Units, RSiO 3 / 2 Units and SiO 4 / 2 A silicone resin consisting of a combination of units is preferred. The combination of these four units results in an average unit formula RaSiO (4-a ) / 2 In the formula, a may be 1.2 to 2. From the viewpoint of obtaining sufficient coating durability, the component (B) R in silicone resin 2 SiO 2 / 2 The content of the unit in the structure is preferably 30 mol % or less.

[0019] The silicone resin of component (B) may be a mixture of multiple silicone resins that satisfy the above average unit formula. The use of such a mixture is preferred because it makes it easier to adjust the film strength, durability, and favorable feel of the resulting cosmetic.

[0020] When using a mixture of multiple silicone resins that satisfy the above average unit formula as the silicone resin of component (B), R 3 SiO 1 / 2 Units and RSiO 3 / 2 Silicone resin with R units as its main component 3 SiO 1 / 2 Units and SiO 4 / 2 Silicone resins containing the unit as the main component can be used in a ratio of 1 / 4-4 / 1.

[0021] If the silicone resin of component (B) has a thermal softening point below 50°C, the film formed after application of the cosmetic to the skin will feel sticky, resulting in poor usability. The thermal softening point can be measured based on the softening point measurement method (return ball method) of JIS K2207. The silicone resin of component (B) preferably has a thermal softening point of 60°C or higher, more preferably 70°C or higher.

[0022] The cosmetic preparation of the present invention preferably contains the components (A) and (B) in a total amount of 1 to 50 mass %, more preferably 3 to 30 mass %, and even more preferably 3 to 20 mass %.

[0023] With respect to the content of each component in the cosmetic of the present invention, where the total content of components (A) and (B) in the cosmetic is 100% by mass, the content of component (A) is preferably 50 to 95% by mass, and more preferably 60 to 90% by mass, and the content of component (B) is preferably 5 to 50% by mass, and more preferably 10 to 40% by mass.
