The present invention relates to a cosmetic containing organosiloxane.
Silicones typified by dimethylpolysiloxane have features such as a light touch, good spreadability, excellent water-repellency, and high safety, and therefore in recent years, silicones have been widely used as an oil agent in cosmetics.
For example, Patent Document 1 discloses that a cosmetic containing a volatile cyclic siloxane such as octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), dodecamethylcyclohexasiloxane (D6), etc. exhibits a light feeling when applied to the skin, good spreadability, and excellent water-repellency.
In recent years, in certain cases, linear dimethyl silicone oil having a kinematic viscosity of 2 mm2/s or less (at 25° C.) has been studied as an alternative to cyclic silicone. However, the usability and stability of the cosmetic deteriorate in some cases, because there are cases where the dimethyl silicone oil has poor compatibility with a polar oil agent and thus cannot be mixed therewith in a clear state.
On the other hand, it is also known that a phenyl-modified silicone, long-chain alkyl-modified silicone and the like are used to enhance the compatibility with a polar oil agent. However, such silicones are less volatile than cyclic siloxanes, and therefore, they lose their light feeling when applied to the skin, and in makeup cosmetics, they are slow to complete forming of coating-film and are prone to cause color migration in some cases.
Meanwhile, for the purpose of providing an alternative to formulate a composition containing volatile oils, Patent Document 2 proposes a composition which contains at least one non-cyclic volatile silicone oil and has a specific evaporation profile. However, it is impossible to find out a description on formulation embodiments other than decamethyltetrasiloxane and dodecamethylpentasiloxane in the document, and the document does not consider the usability nor the stability of cosmetics.
The present invention has been made in view of the above circumstances. An object of the present invention is to provide a cosmetic which can provide a light feeling, good spreadability and a uniform cosmetic film, and exhibit excellent stability over time and excellent cosmetic durability.
To solve the above problems, the present invention provides a cosmetic comprising:
wherein R each independently may be identical to or different from one another and represents a group selected from the group consisting of a hydrogen group, a hydroxy group, and a monovalent hydrocarbon group having 1 to 3 carbon atoms, and “a” is an integer from 1 to 5, provided that at least one of R is a monovalent hydrocarbon group having 2 or 3 carbon atoms; and
The inventive cosmetic includes the organosiloxane(s) shown by the general formula (1) as the component (A) in a base composition, and thus, can provide a light feeling, good spreadability, excellent water repellency, and a uniform cosmetic film. In addition, it is possible to provide the cosmetic which is excellent in stability over time and cosmetic durability even in a mixture system with various oil agents such as silicone oil, hydrocarbon oil, ester oil, etc., an oil-based component being solid at 25° C., or an organic ultraviolet absorber. Further, by virtue of mixing with volatile oil, which is different from the component (A) and has a kinematic viscosity at 25° C. of 2 mm2/s or less, as the component (B), the light feeling is not impaired even when containing the above oil-based component. Furthermore, the completion of coating film can be accelerated, and it is possible to obtain makeup cosmetics with the difficulty of color migration.
That is the inventive cosmetic can provide a light feeling, good spreadability, excellent water repellency, and a uniform cosmetic film, and further can achieve favorable usability without giving a strong oily feeling. Furthermore, even when containing a polar oil agent, the inventive cosmetic can exhibit excellent stability over time and excellent cosmetic durability.
In this event, in the formula (1) of the organosiloxane as the component (A), “a” is preferably 2.
The cosmetic containing such an organosiloxane can achieve more favorable usability without giving a strong oily feeling and can have excellent stability over time and excellent cosmetic durability even when containing a polar oil agent.
Further, it is more preferable that the organosiloxane as the component (A) is a compound selected from the group consisting of 3,5-diethyl-1,1,1,3,5,7,7,7-octamethyltetrasiloxane, 3,3-diethyl-1,1,1,5,5,7,7,7-octamethyltetrasiloxane, 1,3-diethyl-1,1,3,5,5,7,7,7-octamethyltetrasiloxane, 1,5-diethyl-1,1,3,3,5,7,7,7-octamethyltetrasiloxane, 1,7-diethyl-1,1,3,3,5,5,7,7-octamethyltetrasiloxane, 3,5-dipropyl-1,1,1,3,5,7,7,7-octamethyltetrasiloxane, 3,3-dipropyl-1,1,1,5,5,7,7,7-octamethyltetrasiloxane, 1,3-dipropyl-1,1,3,5,5,7,7,7-octamethyltetrasiloxane, 1,5-dipropyl-1,1,3,3,5,7,7,7-octamethyltetrasiloxane, 1,7-dipropyl-1,1,3,3,5,5,7,7-octamethyltetrasiloxane, and 3-ethyl-5-propyl-1,1,1,3,5,7,7,7-octamethyltetrasiloxane.
Such organosiloxane is excellent in compatibility with an organic ultraviolet absorber. Therefore, cosmetics containing such organosiloxane can more surely achieve favorable usability without giving strong oily feeling, and can exhibit excellent stability over time and excellent cosmetic durability even when containing a polar oil agent, especially with an organic ultraviolet absorber.
Further, in the inventive cosmetic, the volatile oil as the component (B) is preferably at least one compound selected from the group consisting of linear dimethyl silicone oils having a kinematic viscosity at 25° C. of less than 2 mm2/s and methyl trimethicone.
The linear dimethyl silicone oils having a kinematic viscosity at 25° C. of less than 2 mm2/s or the methyl trimethicone are excellent in a light feeling, good spreadability, and water repellency when applied to the skin, and thus the cosmetic can exhibit favorable usability, excellent stability over time and excellent cosmetic durability.
Additionally, it is preferable that the inventive cosmetic further contains one or more (C) silicone surfactants having a polyether group or a polyglycerin group.
Such cosmetic can exhibit more favorable usability, more excellent stability over time, and more excellent cosmetic durability.
As described above, the inventive cosmetic can provide a light feeling, good spreadability, and a uniform cosmetic film, and exhibit excellent stability over time and excellent cosmetic durability.
As noted above, it has been desired to develop cosmetics which can provide a light feeling, good spreadability, uniform cosmetic film, and exhibit excellent stability over time and excellent cosmetic durability.
As a result of their diligent study of the above problems, the inventor found that a cosmetic containing organosiloxane having specific structure as a component (A) and volatile oil which is different from the component (A) and has a kinematic viscosity at 25° C. of 2 mm2/s or less as a component (B) can provide a light feeling, good spreadability, excellent water repellency and a uniform cosmetic film, and exhibit excellent stability over time and excellent cosmetic durability, and then have completed the present invention.
That is, the present invention relates to cosmetic comprising (A) organosiloxane represented by the following formula (1), and having a boiling point in a range of 205 to 255° C. and a kinematic viscosity at 25° C. of less than 5 mm2/s,
wherein R each independently may be identical to or different from one another and represents a group selected from the group consisting of a hydrogen group, a hydroxy group, and a monovalent hydrocarbon group having 1 to 3 carbon atoms, and “a” is an integer from 1 to 5, provided that at least one of R is a monovalent hydrocarbon group having 2 or 3 carbon atoms; and
Hereinafter, the present invention is described in detail, however, the present invention is not limited thereto.
Herein, component names may be written according to Japanese Labeling Name of Cosmetic Ingredient (hereinafter, Labeling Name) or International Nomenclature of Cosmetic Ingredients (INCI). Regarding component having Japanese Labeling Name corresponding to that of INCI, the English description of the Labeling Name may be omitted.
The inventive cosmetic comprises:
By virtue of including organosiloxane having the above specific structure as the component (A) and volatile oil different from the component (A) and having a kinematic viscosity at 25° C. of 2 mm2/s or less as the component (B), the inventive cosmetic can provide have a light feeling, good spreadability, excellent water repellency, and a uniform cosmetic film, and can exhibit excellent stability over time and cosmetic durability without impairing a light feeling. Furthermore, the completion of coating film can be accelerated, and it is possible to obtain makeup cosmetics with the difficulty of color migration.
The inventive cosmetic can further contain optional components other than the components (A) and (B).
Essential components and optional components of the inventive cosmetic are described below. It should be noted that examples of optional components are listed in the latter section, but examples that meet the definition of the component (A) or (B), which are essential components, shall be included in the component (A) or (B) the definition of which the examples meet.
The component (A) which is an essential component for the inventive cosmetic is organosiloxane which is represented by the following formula (1) and has a boiling point in a range of 205 to 255° C. and a kinematic viscosity at 25° C. of less than 5 mm2/s,
wherein, R each independently may be identical to or different from one another and represents a group selected from the group consisting of a hydrogen group, a hydroxy group, and a monovalent hydrocarbon group having 1 to 3 carbon atoms, and “a” is an integer from 1 to 5, provided that at least one of R is a monovalent hydrocarbon group having 2 or 3 carbon atoms.
In the above formula (1), each R each independently may be identical to or different from one another, and represents a group selected from the group consisting of a hydrogen group, a hydroxy group, and a monovalent hydrocarbon group having 1 to 3 carbon atoms. Examples of the monovalent hydrocarbon group include a methyl group, an ethyl group, and a propyl group. Provided that at least one of R is a monovalent hydrocarbon group having 2 or 3 carbon atoms, specific examples thereof include an ethyl group and a propyl group.
In the above formula (1), “a” is preferably 2. Cosmetic including such organosiloxane can achieve a more favorable usability without giving a strong oily feeling and exhibit excellent stability over time and excellent cosmetic durability even when blended with a polar oil agent.
Because the (A) organosiloxane in the present invention has a boiling point in a range of 205 to 255° C. and is volatile, the inventive cosmetic does not give a strong oily feeling after applying it to the skin. When the boiling point is lower than 205° C., it becomes difficult to have good spreadability. When the boiling point is higher than 255° C., the cosmetic gives a strong oily feeling. In the present invention, the boiling point refers to the boiling point under an atmospheric pressure of 1013 hPa.
Furthermore, because the (A) organosiloxane in the present invention has a kinematic viscosity at 25° C. of less than 5 mm2/s, the inventive cosmetic can have good spread feeling similarly as a case using decamethylcyclopentasiloxane having a kinematic viscosity of 4 mm2/s (at 25° C.) or the like, and can give a favorable usability without giving a significant sticky feeling. When the kinematic viscosity at 25° C. is 5 mm2/s or higher, the cosmetic is poor in usability due to poor spreadability and a sticky feeling. It should be noted that in the present invention, the kinematic viscosity is a value measured at 25° C. by using a Cannon-Fenske viscometer described in JIS Z 8803:2011.
The organosiloxane as the component (A) of the present invention is preferably a compound selected from the group consisting of 3,5-diethyl-1,1,1,3,5,7,7,7-octamethyltetrasiloxane, 3,3-diethyl-1,1,1,5,5,7,7,7-octamethyltetrasiloxane, 1,3-diethyl-1,1,3,5,5,7,7,7-octamethyltetrasiloxane, 1,5-diethyl-1,1,3,3,5,7,7,7-octamethyltetrasiloxane, 1,7-diethyl-1,1,3,3,5,5,7,7-octamethyltetrasiloxane, 3,5-dipropyl-1,1,1,3,5,7,7,7-octamethyltetrasiloxane, 3,3-dipropyl-1,1,1,5,5,7,7,7-octamethyltetrasiloxane, 1,3-dipropyl-1,1,3,5,5,7,7,7-octamethyltetrasiloxane, 1,5-dipropyl-1,1,3,3,5,7,7,7-octamethyltetrasiloxane, 1,7-dipropyl-1,1,3,3,5,5,7,7-octamethyltetrasiloxane, and 3-ethyl-5-propyl-1,1,1,3,5,7,7,7-octamethyltetrasiloxane. Such organosiloxane is excellent in compatibility with an organic ultraviolet absorber. Therefore, cosmetic including such organosiloxane can more surely achieve a more favorable usability without giving a strong oily feeling, and exhibit excellent stability over time and excellent cosmetic durability even when containing a polar oil agent, especially an organic ultraviolet absorber.
As the (A) organosiloxane of the present invention, a commercially available product may be used. Specific examples include KF-4422 manufactured by Shin-Etsu Chemical Co., Ltd.
The (A) organosiloxane of the present invention can be used in combination with any component by virtue of being excellent in compatibility with general purpose ingredients which can be contained in a variety of cosmetics. Especially, the (A) organosiloxane is excellent in compatibility with an organic ultraviolet absorber such as ethylhexyl methoxycinnamate. Further, in case of containing silicone to have a light usability, the (A) organosiloxane can produce cosmetics excellent in stability over time and excellent cosmetic durability.
Furthermore, when used in combination with an oil-based component being solid at 25° C., stick-like formulation can be easily prepared without interfering with the solidification of the oil-based component. Examples of oily components being solid at 25° C. include polyethylene, ceresin, ozokerite, beeswax, microcrystalline wax, stearyl alcohol, behenyl alcohol, cetanol, etc.
As described above, by virtue of using the (A) organosiloxane of the present invention, the cosmetic can provide a light feeling, good spreadability, excellent water repellency, and a uniform cosmetic film, and further can achieve favorable usability without giving a strong oily feeling. Furthermore, even in a mixture system with various oil agents such as an organic ultraviolet absorber, silicone, hydrocarbon oil, ester oil, or with an oil-based component being solid at 25° C., the cosmetics can be excellent in stability over time and cosmetic durability. Additionally, stick-like formulation can also be easily prepared.
For the (A) organosiloxane of the present invention, usability and volatilization rate can also be adjusted by combination of two or more kinds which are different in kinematic viscosity. For the purpose of achieving moderate volatilization rate, strict adjustment is not required, and one kind can be also used solely for the cosmetic.
The content of the component (A) is not specifically limited, but is preferably 1 to 70 mass % relative to the mass of the entire cosmetic.
The component (B) of the present invention is volatile oil having a kinematic viscosity at 25° C. of 2 mm2/s or less, provided that the component (B) excludes organosiloxane as the component (A). In the present invention, volatile oil refers to oil having a boiling point of 250° C. or less under an atmospheric pressure of 1013 hPa.
A cosmetic which contains the component (A) but does not contain volatile oil having a kinematic viscosity at 25° C. of 2 mm2/s or less cannot exhibit both properties of a light feeling and excellent cosmetic durability.
The component (B) is not limited as long as it is volatile oil having a kinematic viscosity at 25° C. of 2 mm2/s or less, and one kind of oil can be used solely or the mixture of two kinds or more can be appropriately used. The specific examples thereof include oil-based volatile component such as dimethylpolysiloxane (KF-96A-1cs, KF-96L-1.5cs, KF-96L-2cs, and the like;

Among these, linear dimethylsilicone oil having a kinematic viscosity of less than 2 mm2/s is most preferable in terms of versatility and usability. The linear dimethylsilicone oil having a kinematic viscosity of less than 2 mm2/s is more volatile than the component (A), and thus the cosmetic having adjusted volatilization rate and difficulty of color migration can be obtained. The other preferable examples of the component (B) can include methyl trimethicone.
The inventive cosmetic may contain, as the component (B), one kind of volatile oil or two or more kinds of volatile oil having different kinematic viscosity.
The content of the component (B) is preferably not less than 1 mass % and not more than 70 mass %, more preferably not less than 1 mass % and not more than 50 mass %, further preferably not more than 30 mass %, relative to the mass of the entire cosmetic.
Further, in the present cosmetic, the mass of the volatile oil as the component (B) (when containing two or more kinds, the total sum thereof) is preferably not less than 0.1% and not more than 6%, more preferably not less than 0.2% and not more than 4%, relative to mass of organopolysiloxane as the component (A). When the mass of volatile oil as the component (B) relative to the mass of organosiloxane as the component (A) is within the preferable range, the cosmetic durability is especially excellent.
The inventive cosmetic preferably contain one or more silicone surfactants having a polyether group or a polyglycerin group as a component (C) as well as the components (A) and (B). The silicone surfactants are, for example, one or more compounds selected from the group consisting of crosslinked silicone surfactants and noncrosslinked silicone surfactants. The component (C) can exhibit good compatibility with components (A) and (B), and can make a cosmetic stable even when an organic ultraviolet absorber is contained. Especially when a noncrosslinked silicone surfactant or a crosslinked silicone surfactant each having an alkyl branch on a silicone main chain is used, the cosmetic is more stable.
The content of the component (C) is preferably in the range of 0.1 to 20 mass % relative to the mass of the entire cosmetic. When contained in 0.1 mass % or more, the silicone surfactant can perform functions of dispersion or emulsification sufficiently. When contained in 20 mass % or less, the cosmetic cannot exhibit a sticky touch on use, so it is preferable. The HLB value of the silicone surfactant is not limited, but it is preferable in the range of 2 to 14.5 to maintain water resistance of the cosmetic.
In noncrosslinked silicone surfactants, a part of methyl group of a linear or branched silicone main chain is substituted with a hydrophilic group such as polyethylene glycol, polyglycerin, etc. Specifically, the component (C) is preferably linear or branched polyoxyethylene-modified organopolysiloxane, linear or branched polyoxyethylene-polyoxypropylene-modified organopolysiloxane, linear or branched polyoxyethylene-alkyl-co-modified organopolysiloxane, linear or branched polyoxyethylene-polyoxypropylene-alkyl-co-modified organopolysiloxane, linear or branched polyglycerin-modified organopolysiloxane, linear or branched polyglycerin-alkyl-co-modified organopolysiloxane, or linear or branched pyrrolidone-modified organopolysiloxane.
