Description

Oil-based cosmetics

[0001] The present invention relates to an oil-based cosmetic, and more particularly to an oil-based cosmetic that has a long-lasting coating and an excellent feel when used.

[0002] Conventionally, in order to improve the wear time of makeup, a film-forming material has been blended to strengthen the applied film. Among the film-forming materials, silicone resins have been widely used due to their good compatibility with volatile oils. Silicone resins are resins composed of siloxane bonds. The units that make up the siloxane skeleton include M units (monofunctional), D units (bifunctional), T units (trifunctional), and Q units (tetrafunctional), depending on the number of functional groups. MQ resins, MT resins, MD resins, and the like, which are arbitrary combinations of these, exist. Generally, the more functional groups a unit contains, the harder a film tends to be formed, while the fewer functional groups a unit contains, the more flexible a film tends to be formed. Therefore, when using silicone resins as film-forming agents, it is known that using MQ resins containing Q units results in a strong film and improves the wear time of makeup. However, the incorporation of MQ resins can sometimes cause discomfort, such as stickiness and dryness, after application to the skin.

[0003] For example, Patent Document 1 describes that a cosmetic product with improved long-lasting properties and transfer resistance has been obtained by using polypropylsilsesquioxane, a silicone resin containing T units, in combination with a specific phenylated oil as a non-volatile oil and a glyceryl ester, silica, or wax as a gelling agent.

[0004] On the other hand, in cosmetics that use silicone resin as a film-forming agent, if the amount of volatile oil blended together with the silicone resin is large, a feeling of tightness or dryness may occur after application to the skin. Also, depending on the type of silicone resin used and the oil combined, film-forming properties may be deteriorated or the feel after application may be poor, making it difficult to achieve both film-forming properties and a feel after use.

[0005] Patent No. 6038952

[0006] The present invention aims to provide an oil-based cosmetic which has a long-lasting coating film, has little stickiness immediately after application, and little dryness after application, and is excellent in feel when used.

[0007] As a result of extensive research into solving the above-mentioned problems, the present inventors discovered that by blending a silicone resin with a specific non-volatile oil, it is possible to obtain an oil-based cosmetic that has a long-lasting coating film, is free from a sticky feeling immediately after application, and does not feel dry after application, and has an excellent feel when used, and thus completed the present invention.

[0008] That is, the present invention provides an oil-based cosmetic comprising a non-volatile oil and a volatile oil, wherein the non-volatile oil comprises: (A) a silicone resin; (B) 10% by mass or more of trimethylpentaphenyltrisiloxane relative to the total amount of the cosmetic; and (C) an ester oil having a viscosity of 100 mPa s or more.

[0009] In the oil-based cosmetic of the present invention, by blending (A) a silicone resin with a non-volatile oil containing (B) trimethylpentaphenyltrisiloxane and (C) an ester oil in combination, film-forming properties are improved and the long-lasting durability of the applied film is increased. As a result, the cosmetic lasts longer. Furthermore, the cosmetic can be made to have an excellent feel when used, without any sticky feeling immediately after application or dry feeling after application (tight feeling due to dryness).

[0010] The oily cosmetic of the present invention contains non-volatile oils and volatile oils. "Non-volatile oils" are, for example, oily components that remain on the skin at room temperature and atmospheric pressure (normal temperature and normal pressure). In this specification, "non-volatile oils" refers to oily components that have an evaporation rate of 0.01 mg / cm at normal temperature and normal pressure. ２ / min is defined as "non-volatile oil." The oil-based cosmetic of the present invention is characterized in that the non-volatile oil contains a combination of (A) a silicone resin, a predetermined amount of (B) trimethylpentaphenyltrisiloxane, and (C) an ester oil of a specific viscosity. This is described in detail below.

[0011] (A) Silicone Resin The silicone resin (A) (hereinafter sometimes referred to as "Component A") used in the oily cosmetic of the present invention is not particularly limited as long as it is one that is commonly used in cosmetics. That is, the silicone resin (A) (hereinafter sometimes referred to as "Component A") may be any silicone resin that is commonly used in cosmetics. ３ SiO １ / ２ )), dialkylsiloxy units (D units (R ２ SiO ２ / ２ )), monoalkylsiloxy units (T units (RSiO ３ / ２ )), tetrafunctional siloxy units (Q units (SiO ４ / ２ )) may be a silicone resin composed of any combination thereof. Specific examples include solid silicone network compounds known as MQ resins, MT resins, MDQ resins, MTQ resins, MDTQ resins, TD resins, TQ resins, TDQ resins, or TDQ resins. The substituents (R) bonded to silicon in these silicone resins each independently represent a hydrocarbon-based substituent such as an alkyl group, a phenyl group, an alkenyl group, or an aryl group. The hydrocarbon-based substituent preferably has 1 to 10 carbon atoms, and some or all of the hydrogen atoms may be substituted with fluorine atoms or other organic functional groups.

[0012] Examples of MQ resins (silicone resins consisting of M units and Q units) include trimethylsiloxysilicate, trifluoroalkyldimethyltrimethylsiloxysilicate, and phenylpropyldimethylsiloxysilicate. These are also commercially available, and examples include X-21-5250 (trimethylsiloxysilicate, 50% cyclopentasiloxane solution), KF-7312T (trimethylsiloxysilicate, 60% methyltrimethicone solution), KF-7312J (trimethylsiloxysilicate, 50% cyclopentasiloxane solution), KF-7312K (trimethylsiloxysilicate, 60% dimethicone solution), and KF-9021 (trimethylsiloxysilicate, 50% cyclopentasiloxane solution). Examples of suitable MQ resins include SR1000 (trimethylsiloxysilicate, manufactured by Momentive Performance Materials), XS66-B8636 (trifluoroalkyldimethyltrimethylsiloxysilicate, 50% dimethicone solution, manufactured by Momentive Performance Materials), and Silshine 151 (phenylpropyldimethylsiloxysilicate, manufactured by Momentive Performance Materials). The MQ resin used as component A in the oil-based cosmetic of the present invention is preferably trimethylsiloxysilicate.

[0013] Examples of silicone resins containing at least one T unit (also referred to herein as "MT resins") include polymethylsilsesquioxane, polypropylsilsesquioxane, polyphenylsilsesquioxane, and (trifluoropropyldimethylsiloxy / trimethylsiloxy)silsesquioxane. These are also available as commercially available products, and examples thereof include SILFORM FLEXIBLE RESIN (polymethylsilsesquioxane, manufactured by Momentive Performance Materials), DOWSIL 670 Fluid (polypropylsilsesquioxane, manufactured by Dow Corning Toray Co., Ltd.), BELSIL PMK POWDER (polymethylsilsesquioxane, manufactured by Wacker Asahi Kasei Silicones), KR-220L (polymethylsilsesquioxane, manufactured by Shin-Etsu Chemical Co., Ltd.), BELSIL SPR 45 VP (polyphenylsilsesquioxane, manufactured by Wacker Asahi Kasei Silicones), and FR-5 ((trifluoropropyldimethylsiloxy / trimethylsiloxy)silsesquioxane, manufactured by Momentive Performance Materials).

[0014] Component A in the oil-based cosmetic of the present invention preferably contains a silicone resin selected from MQ resin and MT resin. Either MQ resin or MT resin may be blended alone, but it is preferable to blend MQ resin. In the oil-based cosmetic of the present invention, it is preferable to use a combination of MQ resin (particularly trimethylsiloxysilicate) and MT resin (particularly polymethylsilsesquioxane).

[0015] The amount of silicone resin (Component A) in the oil-based cosmetic of the present invention is preferably 10 to 30% by mass, more preferably 15 to 25% by mass, based on the total amount of the cosmetic. The amount of silicone resin (Component A) is preferably 20 to 60% by mass, more preferably 30 to 50% by mass, based on the total amount of non-volatile components contained in the cosmetic. If the amount of Component A is less than 10% by mass of the total amount of the cosmetic or less than 20% by mass of the total amount of non-volatile components, poor film-forming properties may result. If the amount exceeds 30% by mass of the total amount of the cosmetic or more than 60% by mass of the total amount of non-volatile components, the comfortable feel during use tends to be lost.

[0016] (B) Trimethylpentaphenyltrisiloxane (B) trimethylpentaphenyltrisiloxane (hereinafter sometimes referred to as "Component B") in the oil-based cosmetic of the present invention is a type of phenyl-modified silicone commonly used in cosmetics. It is also available as a commercially available product, for example, Dow PH-1555 HRI Cosmetic Fluid (manufactured by Dow Corning Toray Co., Ltd.).

[0017] The blending amount of trimethylpentaphenyltrisiloxane (Component B) in the oil-based cosmetic of the present invention is 10% by mass or more, preferably 21% by mass or more, and more preferably 30% by mass or more, based on the total amount of the cosmetic. The upper limit of the blending amount based on the total amount of the cosmetic is not particularly limited, but is, for example, 60% by mass or less, preferably 50% by mass or less. The blending amount of trimethylpentaphenyltrisiloxane (Component B) may range between the above-mentioned lower and upper limits, and examples thereof include 10 to 60% by mass, 10 to 50% by mass, 21 to 60% by mass, 21 to 50% by mass, 30 to 60% by mass, and 30 to 50% by mass.

[0018] Furthermore, the blending amount of trimethylpentaphenyltrisiloxane (Component B) is preferably in the range of 20 to 60% by mass, more preferably 20 to 50% by mass, and even more preferably 36 to 50% by mass, relative to the total amount of non-volatile components. If the blending amount of Component B is less than 10% by mass relative to the total amount of the cosmetic, or less than 20% by mass relative to the total amount of non-volatile components, it may be difficult for the coating film to remain, while if it is blended in at more than 60% by mass of the total amount of the cosmetic or more than 60% by mass of the total amount of non-volatile components, stickiness may occur.

[0019] (C) Ester oil The ester oil (C) in the oil-based cosmetic of the present invention (hereinafter sometimes referred to as "component C") is a non-volatile oil recognized as falling under the category of "ester oil" in the technical field of cosmetics, and is an oil having a viscosity at 20°C of 100 mPa·s or more, preferably 420 mPa·s or more, and more preferably 1000 mPa·s or more (therefore, "component C" of the present invention is sometimes referred to as "ester oil of specific viscosity"). Note that "viscosity" in this specification is a value measured using a B-type viscometer.

[0020] Specific examples of the ester oil (component C) of a specific viscosity in the present invention include, but are not limited to, triisostearin (viscosity: 13,890 mPa·s), trimethylolpropane triisostearate (viscosity: 257 mPa·s), pentaerythrityl tetraethylhexanoate (viscosity: 124 mPa·s), pentaerythrityl tetraisostearate (viscosity: 420 mPa·s), polyglyceryl-6 octacaprylate (viscosity: 369 mPa·s), diisostearyl malate (viscosity: 5,500 mPa·s), polyglyceryl-2 triisostearate (viscosity: 448 mPa·s), and ditrimethylolpropane (isostearic acid / sebacic acid) oligoester (viscosity: 2,380 mPa·s). In the present invention, diisostearyl malate is particularly preferred.

[0021] The blending amount of the ester oil of a specific viscosity (component C) in the oil-based cosmetic of the present invention is 5 to 30% by mass, preferably 10 to 20% by mass, based on the total amount of the cosmetic. The range of 10 to 40% by mass, more preferably 10 to 20% by mass, based on the total amount of non-volatile components is preferred. If the blending amount is less than 5% by mass, granular lumps are likely to occur, while if it is blended in more than 30% by mass, the cosmetic's staying power may be reduced.

[0022] The "non-volatile oil" in the oil-based cosmetic of the present invention may contain other oily components in addition to the essential components A, B, and C described above. For example, the viscosity of the cosmetic can be adjusted by adding an oily (oil-soluble) thickener. Glyceryl esters are preferably used as the oily thickener to be added to the oil-based cosmetic of the present invention. On the other hand, when a hydrocarbon wax such as polyethylene wax is added to the cosmetic of the present invention, the objectives of the present invention, such as long-lasting cosmetic effect and a good feel during use, can be achieved, but granular clumps may form due to interactions with other ingredients. "Granular clumps" refers to clumps of cosmetic that have become granular due to poor adhesion or spreadability to the skin when applied, or small clumps of cosmetic that form when a dried coating film cracks and partially peels over time.

[0023] The glyceryl ester used as the oil-based thickener in the oil-based cosmetic of the present invention is not particularly limited as long as it is one that is commonly used in cosmetics, such as glyceryl tribehenate, glyceryl tristearate, glyceryl tripalmitate, glyceryl trilaurate, glyceryl behenate, glyceryl behenate / polyglyceryl-6 octastearate, and glyceryl (behenate / eicosanedioate). These are also commercially available, and examples thereof include Esteride G-BP (glyceryl tribehenate, manufactured by National Mimatsu Co., Ltd.), Esteride G-S (glyceryl tristearate, manufactured by National Mimatsu Co., Ltd.), Esteride G-P (glyceryl tripalmitate, manufactured by National Mimatsu Co., Ltd.), Esteride G-L (glyceryl trilaurate, manufactured by National Mimatsu Co., Ltd.), Compritol 888 CG ATO (glyceryl tribehenate, manufactured by Gatefosse), TAISET 50-C (glyceryl behenate / polyglyceryl-6 octastearate, manufactured by Taiyo Kagaku Co., Ltd.), and Nomucoat HK-G (glyceryl behenate / eicosanedioate, manufactured by Nisshin Oillio Co., Ltd.). In the oil-based cosmetic composition of the present invention, glyceryl behenate / eicosanedioate is preferred.

[0024] The amount of the oil-based thickener, preferably a glyceryl ester, used in the oil-based cosmetic of the present invention is not particularly limited, as long as it is an amount that is normally added to cosmetics for the purpose of thickening. For example, it is preferably in the range of 1 to 10% by mass, more preferably 2 to 6% by mass, based on the total amount of the cosmetic.

[0025] Furthermore, under the above conditions (evaporation rate at room temperature and normal pressure is 0.01 mg / cm ２ / min) can be blended as "non-volatile oils" to the extent that the effects of the present invention are not impaired. Examples include hydrocarbon oils, higher fatty acids, higher alcohols, fats and oils, ester oils (but other than component C), silicone oils (but other than component B), oil-based pigments, surfactants, etc. The oil-based cosmetic of the present invention may also further blend "powder." In the present invention, the above-mentioned "non-volatile oils" and powders are collectively referred to as "non-volatile components."

[0026] The powder used in the oil-based cosmetic of the present invention is not particularly limited as long as it is one that is commonly used in cosmetics. Examples of such powder include spherical powder, plate-like powder, coloring material, etc.

[0027] Examples of spherical powders include porous spherical powders such as silica; and spherical resin powders such as polymethyl methacrylate, organopolysiloxane elastomer, polystyrene, polyamide resin (nylon), polyethylene, copolymers of styrene and acrylic acid, benzoguanamine resin, polytetrafluoroethylene, and silicone resin.

[0028] Examples of the plate-like powder include inorganic powders such as mica, synthetic mica (synthetic phlogopite), talc, sericite, aluminum oxide, magnesium oxide, zirconium oxide, magnesium carbonate, calcium carbonate, calcium sulfate, chromium oxide, chromium hydroxide, aluminum silicate, magnesium silicate, aluminum magnesium silicate, kaolin, silicon carbide, barium sulfate, bentonite, smectite, and boron nitride; organic powders such as N-acyl lysine; and composite powders such as titanium oxide-coated mica titanium fine particle, zinc oxide-coated mica titanium fine particle, and barium sulfate-coated mica titanium.

[0029] Coloring materials are raw materials that are blended in for the purpose of imparting color to the cosmetic itself or to the skin or lips when applied, and specific examples that can be used include those that are typically blended in oil-based cosmetics, such as organic pigments, colored pigments, white pigments, pearl pigments, and glitter agents.

[0034] The blending amount of powder used in the oil-based cosmetic of the present invention can be appropriately set depending on the purpose of the oil-based cosmetic. From the viewpoint of film-forming ability (strength of the cosmetic film), it is preferable that the blending amount of powder excluding coloring materials be 8% by mass or less of the total amount of the cosmetic.

[0035] The oil-based cosmetic of the present invention contains a "non-volatile component" that is a non-volatile oil plus any powder, and further contains a volatile oil. The inclusion of a volatile oil improves the spreadability of the cosmetic upon application.

[0036] The volatile oil blended into the cosmetic of the present invention may be any oil commonly used in cosmetics, and can be defined, for example, as an oil having a boiling point in the range of 60 to 260°C at normal pressure. In the cosmetic of the present invention, it is preferable to select a volatile oil in which all of the above-mentioned essential components A, B, and C are soluble. Examples include volatile hydrocarbon oils having 8 to 16 carbon atoms, volatile silicone oils, and mixtures thereof. In particular, these volatile oils are selected from branched C8 to C16 alkanes, branched C8 to C16 esters, and mixtures thereof. Isododecane or isohexadecane, isohexyl neopentanoate, and mixtures thereof are particularly preferred, with isododecane being even more preferred. To maximize color durability and a pleasant feel during use, the amount of volatile oil blended is preferably 0.1 to 50% by mass, and even more preferably 1 to 30% by mass, of the total amount of the cosmetic.

[0037] In the oil-based cosmetic of the present invention, the thickening property and colorant dispersibility can be further improved depending on the blended amount of the volatile oil. Specifically, when the blended amount of the volatile oil is 50% by mass or more relative to the total amount of the cosmetic, it is preferable that, relative to the non-volatile components, Component A is 38% by mass or less, Component B is 25% by mass or less, and Component C is 25% by mass or more.

[0038] The oil-based cosmetic of the present invention can be produced in accordance with conventional methods. Its dosage form can be liquid, paste, solid, semi-solid, gel, etc. Among these, the oil-based cosmetic of the present invention is preferably in liquid or paste form.

[0040] The present invention will be described in further detail below with reference to examples, but the present invention is not limited to these examples in any way. Unless otherwise specified, the blending amount means mass % relative to the total amount of the cosmetic. Prior to the examples, the evaluation methods used in the present invention will be described.

[0041] Evaluation method 1. Retention of applied film (color durability) A practical usability test was conducted by a panel of 10 experts. Specifically, the sample was applied to the lips, and the makeup retention after 2 hours of application was scored based on the following scoring criteria. Furthermore, the total score was evaluated based on the following evaluation criteria. "Scoring criteria" 5 points: Very good 4 points: Good 3 points: Average 2 points: Poor 1 point: Very poor "Evaluation criteria" A: Total score is 40 points or more B: Total score is 35 to 39 points C: Total score is 25 to 34 points D: Total score is 24 points or less

[0042] 2. Usability A practical usability test was conducted by a panel of 10 experts. The evaluation items were "absence of tightness" and "absence of stickiness (stickiness)", and each evaluation item was scored based on the following rating criteria. Furthermore, the total score was evaluated based on the following rating criteria. "Rating criteria" 5: Excellent 4: Excellent 3: Average 2: Poor 1: Very poor "Evaluation criteria" A: Total score of 40 points or more B: Total score of 35 to 39 points C: Total score of 25 to 34 points D: Total score of 24 points or less

[0043] 3. Occurrence of Granular Masses A practical usability test was conducted by a panel of 10 experts, who visually observed the appearance and evaluated it based on the following evaluation criteria. "Evaluation criteria" No granular masses were observed = "None" Occurrence of granular masses was observed = "Yes"

[0044] Liquid lipsticks having the compositions shown in Tables 1 to 3 below were prepared according to standard methods. Using the evaluation methods described above, the remaining extent of the applied film (color durability), the feel during use (absence of tightness, absence of stickiness), and the presence or absence of granular lumps were evaluated. The results are also shown in each table.

[0045]

[0046]

[0047]

[0048] As shown in Tables 1 to 3, Examples 1 to 9, which contained a non-volatile oil containing (A) silicone resin, (B) trimethylpentaphenyltrisiloxane, and (C) an ester oil of a specific viscosity, all received excellent ratings for the degree to which the coating film remained (color durability) and the feel in use (lack of tightness and stickiness). On the other hand, Comparative Example 1, which contained only an ester oil with a viscosity of less than 100 mPa s, and Comparative Example 2, in which the amount of trimethylpentaphenylsiloxane blended did not satisfy the specified requirements, showed particularly poor coating film remaining (color durability) and inferior cosmetic wear.

[0049] Example 1, which contained a combination of MQ resin and MT resin, tended to be less sticky than Example 2, which contained only MQ resin as component A. Furthermore, Example 8, which contained glyceryl ester as an oil-based thickener, did not produce granular lumps, but Example 9, which contained polyethylene wax, produced granular lumps.
