Description

Oil-based thickener and cosmetics containing the same

[0001] The present invention relates to an oil-based thickener and a cosmetic composition containing the same.

[0002] It is known that, in order to obtain a cosmetic composition that is stable over a long period of time, the oil phase is usually thickened. For example, a cosmetic composition thickened with a crosslinked silicone is known. However, a cosmetic composition thickened with a crosslinked silicone becomes creamy, and it is difficult to stabilize the cosmetic composition at a low viscosity (Patent Document 1).

[0003] Silicone oils spread easily and have a refreshing feel, making them popular in a variety of cosmetics and quasi-drugs, including skin care cosmetics, makeup cosmetics, and hair care products. However, consumer needs and regulatory requirements dictate the inclusion of various oils, such as vegetable oils and UV absorbers.

[0004] To date, water-in-oil cosmetics using organically modified clay minerals and polyether-modified silicones have been provided (Patent Documents 2 and 3). However, there is still room for further research into optimal thickeners that can be used in various cosmetic systems, including silicone oils and hydrocarbon oils.

[0005] Furthermore, because organically modified clay minerals are hydrophobized with long-chain alkyl groups, they swell when surfactants are adsorbed onto their surface, thereby exhibiting their thickening properties. This thickening effect is thought to be achieved by improving the dispersibility of the organically modified clay minerals, and insufficient swelling and dispersion can sometimes impair the thickening effect and its durability.

[0007] The present invention has been made in view of the above circumstances, and aims to provide an oil-based thickener that can be easily incorporated into a variety of cosmetic systems and thickens compositions containing oily components, as well as a cosmetic preparation containing the same and having excellent emulsion stability.

[0008] As a result of extensive research into achieving the above-mentioned object, the present inventors have discovered that the above-mentioned object can be achieved by an oil-based thickener containing (A) an organically modified clay mineral, (B) a silicone surfactant having an alkyl branched chain, and (C) a silicone oil having an alkyl group having 6 to 18 carbon atoms, and have thus completed the present invention.

[0009] Accordingly, the present invention provides the following inventions. 1. An oil-based thickener for thickening a composition containing an oily component, comprising (A) an organically modified clay mineral, (B) a silicone surfactant having an alkyl branched chain, and (C) a silicone oil having an alkyl group having 6 to 18 carbon atoms (excluding the above-mentioned component (B)). 2. The oil-based thickener according to 1, wherein the mass ratio (B) / (A) of component (B) to component (A) is 0.7 to 5.0. 3. The oil-based thickener according to 1 or 2, wherein component (B) is a polyether-modified silicone having an alkyl chain having 6 or more carbon atoms as a branch on the silicone main chain. 4. The oil-based thickener according to any one of 1 to 3, wherein component (C) is caprylyl methicone. 5. The oil-based thickener according to any one of 1 to 4, wherein the amount of component (A) in the oil-based thickener is 5 to 40 mass%. 6. The oil-based thickener according to any one of 1 to 5, wherein component (A) is one or more selected from dimethyl distearyl ammonium hectorite, dimethyl distearyl ammonium bentonite, and dimethyl distearyl ammonium-modified montmorillonite. 7. The oil-based thickener according to any one of 1 to 6, wherein the total amount of components (A) to (C) is 90 mass% or more in the oil-based thickener. 8. The oil-based thickener according to any one of 1 to 7, which does not contain a volatile organosiloxane. 9. A cosmetic preparation comprising the oil-based thickener according to any one of 1 to 8. 10. The cosmetic preparation according to 9, which is a water-in-oil cosmetic preparation.

[0010] According to the present invention, it is possible to provide an oil-based thickener that can be easily incorporated into a variety of cosmetic systems and thickens compositions containing oily components, as well as a cosmetic preparation that incorporates the same and has excellent emulsion stability.

[0011] The present invention will be described in detail below. In the present invention, ingredient names may be written as cosmetic names or International Nomenclature of Cosmetic Ingredients (INCI). When the cosmetic name corresponds to the INCI, the cosmetic name or the English name may be omitted.

[0012] [Component (A)] Component (A) of the present invention is an organically modified clay mineral. It is obtained by reacting a water-swelling clay mineral with a cationic surfactant that generates organic cations such as organic ammonium ions, thereby ion-exchanging the exchangeable cations contained in the water-swelling clay mineral with the organic cations. There are no particular limitations on the type of component (A) as long as it is usable in cosmetics, and it can be used alone or in combination of two or more types.

[0013] Examples of water-swellable clay minerals, i.e., smectite clay minerals, include natural or synthetic clay minerals such as montmorillonite, beidellite, nontronite, saponite, and hectorite. Examples of cationic surfactants used to modify the clay minerals include quaternary ammonium salts such as dialkyldimethylammonium salts, alkyltrimethylammonium salts, alkyldimethylammonium salts, and alkyldimethylbenzylammonium salts, as well as phosphonium salts, sulfonium salts, imidazolium salts, and pyridinium salts. Specific examples of component (A) include dimethyldistearylammonium hectorite (quaternium-18 hectorite, disteardimonium hectorite), dimethyldistearylammonium bentonite (quaternium-18 bentonite, quaternium-90 bentonite), dimethyldistearylammonium-modified montmorillonite, dioctadecyldimethylammonium salt-modified montmorillonite, octadecyldimethylbenzylammonium salt-modified montmorillonite, and dihexadecyldimethylammonium salt-modified montmorillonite. Among these, one or more selected from dimethyldistearylammonium hectorite, dimethyldistearylammonium bentonite, and dimethyldistearylammonium-modified montmorillonite are preferred.

[0014] The amount of component (A) in the oil-based thickener is preferably 5 to 40% by mass, more preferably 5 to 30% by mass, and even more preferably 10 to 25% by mass. The more component (A) in the oil-based thickener, the more the amount of oil-based thickener added to the cosmetic can be reduced, which is preferable as it increases the degree of freedom in cosmetic formulation. However, from the viewpoint of ease of incorporation into cosmetics, it is preferable to prevent the viscosity and hardness of the oil-based thickener itself from becoming too high.

[0015] [Component (B)] Component (B) of the present invention is a silicone surfactant having an alkyl branched chain. It preferably has a polyether group as the hydrophilic group. Specifically, polyether-modified silicones having alkyl chains with 6 or more carbon atoms as branches on the silicone main chain are preferred. More specifically, examples include non-crosslinked silicones having a hydrophilic polyether group in the main chain organopolysiloxane (e.g., dimethicone) and a hydrophobic moiety structure in which some of the methyl groups directly bonded to the silicon atoms of the organopolysiloxane are substituted with alkyl groups with 6 or more carbon atoms. Examples include linear or branched polyoxyethylene / alkyl-co-modified organopolysiloxanes, linear or branched polyoxypropylene / alkyl-co-modified organopolysiloxanes, and linear or branched polyoxyethylene / polyoxypropylene / alkyl-co-modified organopolysiloxanes. The alkyl chain length is not particularly limited, but C10 to C20 is preferred, and C12 to C16 is even more preferred in terms of compatibility. Specific examples include lauryl PEG-9 polydimethylsiloxyethyl dimethicone and cetyl PEG / PPG-10 / 1 dimethicone, which are commercially available under the trade names KF-6038 and KF-6048 (manufactured by Shin-Etsu Chemical Co., Ltd.).

[0016] Since component (B) is incorporated for the purposes of improving the dispersibility of component (A) in the oil-based thickener and the cosmetic, and for the purposes of emulsifying water in the cosmetic, it is preferable that it is compatible with component (C) and the oil used in the cosmetic. Polyether-modified silicone surfactants with alkyl branched chains are compatible with low-viscosity silicone oils to non-polar oils. In particular, lauryl PEG-9 polydimethylsiloxyethyl dimethicone and cetyl PEG / PPG-10 / 1 dimethicone are easily used in formulations that incorporate polar oils such as ester oils, and can produce emulsions with relatively high viscosity.

[0017] The amount of component (B) in the oil-based thickener is preferably 5 to 90% by mass, more preferably 5 to 40% by mass, even more preferably 10 to 30% by mass, and particularly preferably 12 to 30% by mass. By using a content of 5% by mass or more, an oil-based thickener with more sufficient thickening properties can be obtained. While it is possible to increase the amount in the oil-based thickener, this increases the amount used as an emulsifier in the cosmetic, which may reduce the flexibility of cosmetic formulation.

[0018] [Component (C)] Component (C) of the present invention is a silicone oil (C) having an alkyl group containing 6 to 18 carbon atoms. Unlike the surfactant component (B), component (C) does not have a hydrophilic group. For example, a modified silicone having a structure in which an alkyl group containing 6 to 18 carbon atoms is bonded as a side chain to a linear polysiloxane skeleton can be used. The number of carbon atoms in the alkyl group is preferably 6 to 10, more preferably 7 to 9, and most preferably 8. Caprylyl methicone, in which an octyl group is modified to a trisilicone, is preferred. Specifically, this is commercially available under the trade name KF-4418 (manufactured by Shin-Etsu Chemical Co., Ltd.).

[0019] Component (C) is compatible with a wide range of surfactants, oils, film-forming agents, etc. added to cosmetics, and does not interfere with the dispersion of component (A) by component (B), allowing for stable incorporation. On the other hand, hydrocarbon oils that are not component (C) limit the incorporation of silicone oils into cosmetics. Furthermore, silicone oils other than component (C) also limit the incorporation of hydrocarbon oils into cosmetics. Oils with polar groups, such as ester groups, tend to hinder the thickening of component (A) in cosmetic formulations and reduce emulsion stability. Furthermore, volatile oils undergo compositional changes due to evaporation, making them unsuitable for the present invention. Component (C) avoids these problems and allows for stable incorporation. A high molecular weight reduces compatibility with other ingredients, while a low molecular weight leads to volatility, which can dry out the raw materials and cause skin irritation. Therefore, silicone oils with alkyl groups having 6 to 18 carbon atoms are selected.

[0020] The amount of component (C) in the oil-based thickener is preferably 10 to 95% by mass, more preferably 20 to 90% by mass, even more preferably 30 to 80% by mass, and most preferably 50 to 80% by mass. By using this range, the oil-based thickening effect of the present invention becomes more stable.

[0021] The mass ratio (B) / (A) relative to the (A) component is preferably 0.7 to 5.0, more preferably 1.0 to 4.0, and even more preferably 1.2 to 2.0. A higher content of the (A) component in the oil-based thickener allows for a reduced amount of the oil-based thickener to be added to a cosmetic, providing greater flexibility in cosmetic formulation. However, from the standpoint of ease of incorporation into cosmetics, it is preferable to prevent the viscosity and hardness of the oil-based thickener itself from increasing. Therefore, by making the mass ratio (B) / (A) relative to the (A) component 1.0 or more, the viscosity and hardness of the oil-based thickener can be further reduced. On the other hand, by making the (B) / (A) ratio 5.0 or less, a decrease in formulation flexibility can be more effectively prevented, and the effects of incorporation of an excess surfactant on thickening and viscosity stability can also be more effectively prevented.

[0022] In the oil-based thickener of the present invention, the total content of components (A) to (C) is preferably 90% by mass or more, more preferably 95 to 100% by mass, and even more preferably 99 to 100% by mass. By making the total content of components (A) to (C) 90% by mass or more, the influence of components other than components (A) to (C) is reduced, and an oil-based thickener with better stability can be produced.

[0023] The optional components in the oil-based thickener are not particularly limited as long as they do not impair the effects of the present invention, but it is preferable not to include a volatile organosiloxane in order to prevent changes in composition due to evaporation. Generally, volatile organosiloxanes have high dispersibility for component (A), and stable oil-based thickeners can often be obtained, but in the present invention, a stable oil-based thickener can be obtained even without including a volatile organosiloxane.

[0024] [Oil-based Thickener] In the present invention, the oil-based thickener thickens a composition containing an oily component. Examples of the oily component include the above-mentioned component (C) and (1) oily components such as silicone oil and hydrocarbon oil described below. The composition is preferably an emulsion composition.

[0025] If component (A) is blended into a cosmetic without using the oil-based thickener of the present invention, there is a risk that the powder will become airborne and stick to the container wall, or that lumps will form, making it difficult to prepare a uniform oil gel. Furthermore, if swelling and dispersion are insufficient, the thickening effect and its durability may be impaired, and therefore the effects of the present invention cannot be obtained even if components (A) to (C) are blended into a cosmetic without using the oil-based thickener of the present invention.

[0026] The hardness of the oil-based thickener of the present invention, as measured with a rheometer such as a Rheometer RT-2002D.D (manufactured by Rheotec Corporation, measuring probe: 10 mmφ, needle penetration depth: 10 mm, sample stage rising speed: 5 cm / min, temperature: 25°C, range: 200), is preferably 1 to 100, more preferably 5 to 70, and even more preferably 5 to 30. By setting the hardness within this range, the oil-based thickener can be more easily incorporated into cosmetics.

[0027] [Method for producing oil-based thickener] When preparing the oil-based thickener of the present invention, there are no particular limitations on the method or equipment used, and any known method can be used, as long as it can homogenize the entire highly viscous gel while applying strong shear. For example, a kneader equipped with a dispersing mixer can be used. In a method for producing the oil-based thickener of the present invention, components (A) to (C) are mixed and heated in the swollen gel state, and shear is applied to improve dispersibility and further improve the thickening effect.

[0028] [Cosmetics] The cosmetic of the present invention is a cosmetic (composition) containing an oil-based thickener, and can provide a cosmetic with excellent emulsion stability, preferably excellent usability. The cosmetic is not particularly limited, but examples include skin care cosmetics, makeup cosmetics, antiperspirant cosmetics, UV protection cosmetics, and other cosmetics applied to the skin, hair cosmetics, and other cosmetics applied to the hair, as well as nail cosmetics. Examples of skin care cosmetics include lotions, emulsions, creams, cleansers, face packs, oily liquids, massage products, beauty serums, beauty oils, detergents, deodorants, hand creams, lip balms, and wrinkle concealers. Examples of makeup cosmetics include makeup primers, foundations, concealers, face powders, blushers, eyeshadows, eyeshadows, mascaras, eyeliners, eyebrow pencils, and lipsticks. Examples of antiperspirant cosmetics include roll-on, cream, solution, and stick types. Examples of UV protective cosmetics include sunscreen oils, sunscreen emulsions, sunscreen creams, and preparations in which the above-mentioned makeup cosmetics are imparted with sunscreen effects, etc. Examples of hair cosmetics include shampoos, rinses, treatments, setting agents, hair dyes, hair fragrances, etc.

[0029] The cosmetic preparation of the present invention may be in any form, for example, a powder, an oily liquid, a water-in-oil emulsion, an oil-in-water emulsion, a non-aqueous emulsion, or a multiple emulsion such as a W / O / W type or an O / W / O type. Furthermore, the cosmetic preparation of the present invention may be in a variety of forms, including liquid, emulsion, cream, solid, paste, gel, powder, pressed, multi-layered, mousse, spray, stick, pencil, etc. Water-in-oil cosmetic preparations are particularly preferred, as they are more likely to produce a stable emulsion according to the present invention.

[0030] The amount of the oil-based thickener of the present invention in the cosmetic is preferably 0.5 to 60% by mass, more preferably 1 to 50% by mass, and even more preferably 3 to 30% by mass. By setting it to 0.5% by mass or more, it is possible to expect stabilization of the cosmetic, and by setting it to 60% by mass or less, it is possible to further improve the feeling in use.

[0031] The cosmetic of the present invention can be obtained, for example, by blending the above-mentioned oil-based thickener. It can also contain various components commonly used in cosmetics to the extent that the effects of the present invention are not impaired. For example, it may contain (1) an oil-based component, (2) an aqueous component, (3) a surfactant, (4) a powder other than component (A), (5) a composition comprising a crosslinked organopolysiloxane and an oil agent that is liquid at room temperature, (6) a film-forming agent, (7) an ultraviolet absorbing / scattering agent, and (8) other additives. These may be used alone or in appropriate combinations of two or more. Individual components contained in the oil-based thickener of the present invention may also be blended into the cosmetic separately from the oil-based thickener. However, simply blending components (A) to (C) of the present invention without blending the oil-based thickener of the present invention will not achieve the significant effects intended by the present invention.

[0084] The present invention will be specifically explained below with reference to examples and comparative examples, but the present invention is not limited to the following examples. In the following examples, unless otherwise specified, "%" in the composition indicates mass % and ratio indicates mass ratio, the blend amount is the blend amount of the blended product described, and the ratio of (B) / (A) is the pure amount (the same applies hereinafter).

[0085] [Examples and Comparative Examples] (Preparation of Oil-Based Thickener) All ingredients were mixed based on the composition shown in Table 1 below, then heated to 50-60°C and mixed uniformly using a disper to obtain an oil-based thickener. The hardness of the obtained oil-based thickener was measured to examine the ease of incorporation into cosmetic formulations. The results are also shown in the table. The hardness is the value measured using a rheometer RT-2002D-D (manufactured by Rheotec Co., Ltd., measurement probe: 10 mmφ, needle penetration depth: 10 mm, sample stage rising speed: 5 cm / min, temperature: 25°C, range: 200).

[0086] (Note 1) Dimethyl distearyl ammonium bentonite: Esben WV (manufactured by Hojun Co., Ltd.) (Note 2) Cetyl PEG / PPG-10 / 1 dimethicone (manufactured by Shin-Etsu Chemical Co., Ltd.) (Note 3) Caprylyl methicone (manufactured by Shin-Etsu Chemical Co., Ltd.)

[0087] As is clear from Table 1, all of the Examples were oil-based thickeners with low hardness that were easy to add to cosmetics. On the other hand, Comparative Example 1, which used ester oil instead of component (C), had high hardness and was difficult to disperse uniformly when added to cosmetics. Furthermore, Examples 1 to 4 were easier to add to cosmetics than Example 5, which had a low (B) / (A) ratio.

[0088] (Composition containing an oil-based thickener) Based on the composition shown in Table 2 below, components (1) and (2) were mixed uniformly, and then (2) was gradually added to (1) and emulsified to prepare an emulsion. The viscosity of the resulting emulsion was measured using a B-type viscometer (TVB-10 model, manufactured by Toki Sangyo Co., Ltd.) at 25°C with spindle No. 3 at 30 revolutions per minute for a measurement time of 30 seconds. The results are also shown in the table.

[0089] (Note 1) An oil-based thickener obtained in the same manner as in Example 3, except that component (A) in Example 3 was changed to the following (Note 2). (Note 2) Dimethyl distearyl ammonium hectorite: Bentone 38 VCG (manufactured by Elementis) (Note 3) Cetyl PEG / PPG-10 / 1 dimethicone: manufactured by Shin-Etsu Chemical Co., Ltd. (Note 4) Caprylyl methicone: manufactured by Shin-Etsu Chemical Co., Ltd.

[0090] Although Example 6 and Comparative Example 2 contained the same overall blended components, Example 6 clearly had a higher viscosity. This increase in viscosity was due to the effect of the oil-based thickener of the present invention, and it became clear that the thickening effect could not be achieved by simply blending the components that make up the oil-based thickener.

[0091] (Compositions containing oil-based thickeners) Emulsions were prepared based on the compositions shown in Table 3 below, and the viscosities were compared. The production method was as follows, and after preparing the oil-based thickener of the present invention, emulsification was performed. The viscosity was measured using a B-type viscometer (TVB-10 model, manufactured by Toki Sangyo Co., Ltd.) at 25°C with spindle No. 4, 6 revolutions per minute, and a measurement time of 30 seconds. The results are also shown in the table.

[0092] (Production method) A: After mixing component (1), the mixture was heated to 50-60°C and mixed uniformly using a disper to obtain an oil-based thickener. B: To a mixture of component (2), the oil-based thickener from A was added and mixed uniformly. C: Component (3) was mixed uniformly, and then gradually added to B and emulsified.

(Note 3) PEG-10 dimethicone (manufactured by Shin-Etsu Chemical Co., Ltd.) (Note 4) Caprylyl methicone (manufactured by Shin-Etsu Chemical Co., Ltd.)

[0094] A stable emulsion was obtained in Example 7, which contained the oil-based thickener of the present invention. On the other hand, sufficient thickening was not obtained in Comparative Example 3, which used a polyether-modified silicone that did not have an alkyl branch in component (1), unlike component (B).
