Description

  The present invention relates to an external composition containing relatively large oil-based particles.

  Oily solid particles, microcapsules, granules and the like that have a size that can be visually observed and that can be contained in a composition for external use such as cosmetics containing a solid oil have already been provided.

  For example, granulation examples in water (see Patent Documents 1 and 2), granulation examples in which a water-soluble organic solvent such as alcohol is added to the aqueous phase (see Patent Document 3), and low molecular surface activity in the aqueous phase. Example of granulation with added agent (see Patent Document 4), Example of granulation with added thickener or protective colloid agent in aqueous phase (see Patent Documents 5 to 7), Addition of lipophilic active agent to oil phase Examples of granulation (see Patent Documents 8 and 9) are known.

  However, the techniques of Patent Documents 1 and 2 recognize the non-uniformity of the particle diameter and the coalescence of the particles. In practical use, it is recognized that it is necessary to perform a process such as sieving.

  Moreover, in the technique of patent document 3, since it uses alcohol, the restrictions on prescription are recognized. Moreover, in the technique of patent document 4, the surface active ability of a low molecular surfactant is too high, and oily particles are easily miniaturized, and setting of manufacturing conditions is extremely difficult. Further, in the techniques of Patent Documents 5 to 7, since the particle size depends on the shear stress at the time of stirring, the examination of the production conditions according to the viscosity is complicated, and further, the particles are isolated from the polymer solution. Difficult to do. Moreover, the technique of patent document 8, 9 has the problem that it is difficult to form uniform particle | grains, and there are many restrictions on prescription.

Furthermore, in Patent Document 10, a semi-solid oily substance mixture composed of a liquid oily substance, a solid oily substance and / or a surface modified pigment is dispersed in a water-soluble thickener solution and stirred. Gel-like cosmetics containing colored oil particles are described. However, the technique of Patent Document 10 still has a problem in usability.

  The problem to be solved by the present invention is to provide an external composition containing oily particles having excellent stability, uniform particle size and excellent usability by a simple production process.

  As a result of intensive studies aimed at solving this problem, the present inventors have dispersed the oily particles containing dextrin fatty acid ester and liquid oil satisfying specific conditions in the composition for external use, thereby achieving the above-mentioned problem. The present invention has been completed.

That is, the present invention provides an external composition (hereinafter, also referred to as “external composition”) in which oily particles containing a dextrin fatty acid ester and a liquid oil satisfying the following conditions are dispersed in an aqueous phase. .
1) Content of dextrin fatty acid ester with respect to the total mass of oil-based particles is 5-40 mass%.
2) The average particle diameter of the oily particles is 0.05 to 10 mm.

  The composition for external use, the composition for external use, and preferably, the composition for external use comprises an oil phase component containing components constituting oily particles, which is heated and melted in an aqueous phase component mainly composed of water. It is produced by adding a mixture of water-soluble components as necessary, while stirring and cooling a mixture of the aqueous phase and the oil phase, and forming oily particles in the aqueous phase. can do.

  INDUSTRIAL APPLICABILITY According to the present invention, an oily particle-dispersed external composition having excellent stability and usability is provided.

A. Oil phase component The oil phase prepared when the composition for external use is produced contains a dextrin fatty acid ester and a liquid oil as described above.

  Examples of dextrin fatty acid esters include one or more of dextrin palmitate, dextrin oleate, dextrin stearate, dextrin myristate, etc., and it is preferable to select dextrin palmitate. .

  Further, the dextrin fatty acid ester is preferably 5 to 40% by mass, particularly preferably 10 to 25% by mass, based on the total mass of the oily particles, that is, the entire oil phase component. . If the content of the dextrin fatty acid ester is less than 5% by mass of the total oil phase component, the oily particles tend to be brittle, and if it exceeds 40% by mass, the oily particles become too hard. In addition, there is a strong tendency to cause problems in the usability of the external composition.

  The liquid oil is a liquid oil at room temperature, for example, linseed oil, camellia oil, macadamia nut oil, corn oil, olive oil, avocado oil, sasanqua oil, castor oil, safflower oil, kyonin oil, cinnamon oil, jojoba oil, Grape oil, almond oil, rapeseed oil, sesame oil, sunflower oil, wheat germ oil, rice germ oil, rice bran oil, cottonseed oil, soybean oil, peanut oil, tea seed oil, evening primrose oil, triglycerin, glycerin trioctanoate, triiso Glycerol palmitate or the like can be used.

  Oils such as coconut oil, palm oil, and palm kernel oil can be used.

  Further, as ester oil, octanoic acid ester such as cetyl octanoate, glycerin tri-2-ethylhexanoate, isooctanoic acid ester such as tetra-2-ethylhexanoic acid pentaerythritol, lauric acid ester such as hexyl laurate, Isopalmitic acid such as isopropyl myristate, octyl dodecyl myristate, palmitic acid ester such as octyl palmitate, stearic acid ester such as isocetyl stearate, isostearic acid ester such as isopropyl isostearate, isopalmitic acid octyl Esters, oleic acid esters such as isodecyl oleate, adipic acid diesters such as diisopropyl adipate, sebacic acid diesters such as diethyl sebacate, diisostearate malate Diisostearyl malate, etc. etc. may be used.

  As the hydrocarbon oil, liquid paraffin, ozokerite, squalane, squalene, pristane, paraffin, isoparaffin, petrolatum and the like can be used, and sterols can also be used.

  Furthermore, as silicone oil, chain silicone such as dimethylpolysiloxane, methylphenylpolysiloxane and methylhydrogenpolysiloxane, cyclic silicone such as decamethylcyclopentasiloxane and dodecamethylcyclohexasiloxane, amino-modified silicone oil, polyether-modified Silicone oil, carboxy-modified silicone oil, alkyl-modified silicone oil, ammonium salt-modified silicone oil, fluorine-modified silicone oil and the like can also be used.

  Further, by containing hydrogenated polyisobutene as the oil phase component, it is possible to easily control the particle diameter while improving the strength of the oil-based particles, and to further improve the usability of the product. A suitable content of the hydrogenated polyisobutene is 0.1 to 40% by mass relative to the total mass of the oily particles, that is, the oil phase component. The mass ratio of hydrogenated polyisobutene to dextrin fatty acid ester (hydrogenated polyisobutene: dextrin fatty acid ester) is preferably 1: 2 to 4: 1.

  In addition, by adding “solid oil having a freezing point of 55 ° C. or higher” to the oil particles (hereinafter also referred to as “specific solid oil”), a film of the specific solid oil is formed on the outside of the oil particles, and the oil particles It becomes possible to suppress adhesion between each other. Further, the freezing point of the specific solid oil is particularly preferably 60 ° C. or higher.

  Specific solid oils satisfying such conditions include, for example, hydrogenated jojoba oil (freezing point: 68 ° C.), glyceryl behenate (freezing point: 66 ° C.), behenyl alcohol (freezing point: 68 ° C.), stearyl alcohol (freezing point: 58 ° C.), solid paraffin (freezing point: 59 to 91 ° C.), microcrystalline wax (freezing point: 80 ° C.), ceresin (freezing point: 68 to 75 ° C.), bees wax (freezing point: 64 ° C.), polyethylene wax (freezing point: 80 C), silicon wax (freezing point: 60 ° C.), batyl alcohol (freezing point: 70 ° C.), carnauba wax (freezing point: 83 ° C.), beeswax (freezing point: 64 ° C.), candelilla wax (freezing point: 71 ° C.), jojo wax ( Freezing point: 55 ° C), Owl (Freezing point: 55 ° C), Hardened castor oil (Freezing point: 84) ), Hydrogenated palm oil (freezing point: 70 ° C.), hydrogenated palm oil (freezing point: 65 ° C.), hydrogenated palm oil (freezing point: 70 ° C.), 12-hydroxystearic acid (freezing point: 70 ° C.), and the like. In particular, behenyl alcohol is preferred.

  The content of the specific solid oil in the oily particles can be freely selected as necessary, but is preferably about 5 to 25% by mass, particularly preferably 8 to 16% by mass with respect to the total mass of the oily particles. %. As described above, when hydrogenated polyisobutene is contained, the mass ratio of hydrogenated polyisobutene, dextrin fatty acid ester and specific solid oil (hydrogenated polyisobutene: dextrin fatty acid ester: specific solid oil) is 1: 2: 1. ˜1: 2: 3 is preferred. When the specific solid oil content is less than the above range, the stickiness becomes worse, the oily particles are aggregated, and the usability tends to deteriorate. On the contrary, when there is more specific solid oil than the said range, the harsh feeling will be manifested and the tendency for skin contact to deteriorate will be recognized. When the amount of polybutene is less than the above range, it tends to be difficult for the oil to harden into a spherical shape, making it difficult to prepare the desired oily particles. On the contrary, when there is more polybutene than the said range, stickiness will become worse, an oil-based particle will aggregate and the tendency for usability to deteriorate will be recognized. When there is more dextrin fatty acid ester than the said range, the tendency for oil to become hard to harden spherically and to prepare the desired oil-based particle | grains will be recognized. On the contrary, when there is more polybutene than the said range, stickiness will become worse, an oil-based particle will aggregate and the tendency for usability to deteriorate will be recognized.

  The most preferable mass ratio of the above hydrogenated polyisobutene, dextrin fatty acid ester and specific solid oil is about hydrogenated polyisobutene: dextrin fatty acid ester: specific solid oil = 1: 2: 2.

  Furthermore, it is possible to alleviate aggregation of oily particles by adhering a hydrophilic powder having an average particle size of 0.02 to 80 μm to the surface of the oily particles. When this average particle size is less than 0.02 μm, it tends to be difficult to prevent aggregation of oily particles, and when it exceeds 80 μm, a tendency to show a rough feeling in use in the oily particles is recognized. Examples of the hydrophilic powder include corn starch, silica powder, titanium oxide powder, zinc oxide powder, iron oxide powder, magnesium oxide powder, barium sulfate powder, aluminum hydroxide powder, alumina, calcium carbonate powder, calcium phosphate powder, and chip. Examples thereof include boron halide powder, talc, mica, pearl agent, cellulose powder, pearlescent pigment, and the like, and one or more of these can be selected and used. Further, the particle shape of the hydrophilic powder is not particularly limited, and a spherical shape, a square shape, an indefinite shape, or the like can be appropriately selected and used. Further, the content of the hydrophilic powder is preferably 0.5 to 5.0% by mass of the total mass of the oily particles. When this content is less than 0.5% by mass of the total mass of the oily particles, the desired effect of suppressing aggregation of the oily particles is not sufficiently exhibited. When the content exceeds 5.0% by mass, the oily particles become hard and feel good to use. The tendency to be damaged is recognized.

  Moreover, it is also possible to contain a general oil-based medicine etc. as an oil phase component. For example, by containing an ultraviolet absorber such as octyl paramethoxycinnamate or t-butylmethoxybenzoylmethane as the oil phase component, an ultraviolet shielding effect can be imparted to the oily particles. Furthermore, the composition can also have an ultraviolet shielding effect by containing an ultraviolet scattering agent (powder particles having an ultraviolet scattering effect), for example, fine particle titanium oxide, fine particle zinc oxide, etc. in the oil phase component. it can. The ultraviolet scattering agent is preferably contained in an oily particle as dispersed as possible. For this reason, the average particle size of the powder particles used as the ultraviolet scattering agent is 0.2 μm or less (lower limit). Although there is no particular limitation, in practice, it is preferably approximately 0.02 μm or more. Further, when the powder particles are subjected to a surface hydrophobization treatment, it is advantageous to ensure dispersibility in the oily particles. As a specific method of the surface hydrophobization treatment, for example, the surface of the powder particles is made of, for example, silicones (methyl hydrogen polysiloxane, dimethyl polysiloxane, alkyl-modified silicone resin, etc.), dextrin fatty acid ester, higher fatty acid, higher alcohol, Examples include hydrophobizing treatment of fatty acid esters, metal soaps, alkyl phosphate ethers, fluorine compounds, or hydrocarbons (such as squalane and paraffin) by a wet method using a solvent, a gas phase method, a mechanochemical method, and the like.

  Also, vitamin A and its derivatives, vitamin D and its derivatives, vitamin E and its derivatives, oil-soluble vitamins such as vitamin K and its derivatives, oil-soluble plant extracts, oil-soluble drugs, oil-soluble fragrances, etc. It can also be contained in the oil phase. In addition, oil-soluble derivatives of water-soluble drugs such as vitamin C and arbutin, and those obtained by hydrophobizing the crystal surface can be contained in the oil phase. By these, each medicinal effect can be imparted to the oily particles, and the drug can be gradually released or stabilized.

  In addition, oil-soluble dyes (red 225, etc.), organic pigments (orange 204, red 202, etc.), pigments (orange 205, yellow 4, blue 1, etc.) rakes (zirconium, barium, aluminum) Etc.), natural pigments (chlorophyll, β-carotene, etc.), yellow iron oxide, red iron oxide, black iron oxide, titanium oxide, zinc oxide, and other inorganic pigment powders (hydrophobized products are preferred) Oily particles can be colored by adding a pearl pigment such as titanium mica, a lame agent composed of a colored plate-like resin, or the like.

  The mass of the oily particles relative to the present composition, that is, the content of the oil phase component relative to the present composition is preferably 0.01 to 30% by mass of the composition, and 5 to 15% by mass. Is particularly preferred. When the oil phase component is less than 0.01% by mass of the composition, the amount of oily particles is so small that it is difficult to recognize the presence of the oily particles in the composition for external use. Among them, the oily particles are in contact with each other, and the tendency of the particles to coalesce is recognized. The average particle diameter of the oily particles tends to depend on the stirring speed when the oil phase component is stirred in the aqueous phase component when the composition for external use is produced. That is, if the stirring speed is far, fine oil particles are formed, and if the stirring speed is slow, huge oil particles are formed.

  The specific stirring speed varies depending on the stirring device and the specific components contained in the composition, and the particle size of the oily particles to be desired also varies depending on the specific application. The range is about 0.05 to 10 mm, preferably about 0.1 to 2 mm, and most often about 1 mm.

B. Aqueous phase component The aqueous phase prepared when producing the composition for external use can be prepared using a general aqueous solvent, specifically, water, ethanol, or the like. Moreover, it is also a suitable aspect to contain a thickener. Suitable thickeners to be contained in the aqueous phase include acrylamide copolymers together with carboxyvinyl polymer, alkyl-modified carboxyvinyl polymer, agar, xanthan gum and the like. Acrylamide copolymers include vinylpyrrolidone / 2-acrylamido-2-methylpropanesulfonic acid copolymer, dimethylacrylamide / 2-acrylamido-2-methylpropanesulfonic acid copolymer, acrylic acid amide / 2-acrylamide- 2-methylpropanesulfonic acid copolymer, mixture of polyacrylic acid amide and sodium polyacrylate, sodium acrylate / 2-acrylamido-2-methylpropanesulfonic acid copolymer, ammonium polyacrylate, polyacrylamide / acrylic acid Examples thereof include ammonium copolymers and acrylamide / sodium acrylate copolymers. Furthermore, other water-soluble components, for example, water-soluble drugs such as arbutin, ascorbic acid glucoside, tranexamic acid, 4-methoxysalicylate, humectants such as glycerin, dipropylene glycol, 1,3-butylene glycol, dimorpholinopiri Water-soluble UV absorbers such as dadinone, chelating agents such as sodium edetate, pH adjusters such as citric acid and sodium citrate, preservatives such as parabens and phenoxyethanol, water-soluble dyes, water-soluble fragrances, moisturizers, interfaces An activator or the like can be contained.

C. Production of Composition for External Use As described above, the composition for external use is preferably a composition comprising oily particles that are heated and melted by heating an aqueous phase component mainly composed of water. Stirring and cooling a mixture of an aqueous phase and an oil phase obtained by adding an oil phase component to be contained, and forming oily particles in the aqueous phase while cooling, and if necessary, various water-soluble components. It can manufacture by adding. In addition, in the above-described embodiment, when a specific solid oil component and / or an ultraviolet scattering agent is contained in the oil particles, these additive components are blended in the oil phase component and the above steps are followed. Thus, a desired composition for external use can be produced. In addition, when a hydrophilic powder having a specific particle size is adhered to the oil phase particle surface, the hydrophilic powder is added to the surface of the oil particle by blending the hydrophilic powder in the aqueous phase component and following the above steps. The composition for external use to which is attached can be produced.

  The mass ratio of the water phase to the oil phase at the time of granulation can be freely selected according to the density per unit volume of the expected oily particles, but in general, the water phase: oil phase = 99.99: 0.01-1: 1 (mass ratio), preferably about 2: 1-5: 1.

  The introduction of the oil phase into the aqueous phase can be preferably carried out in a stirring environment of the aqueous phase. As described above, the stirring speed is preferably adjusted so that the average particle diameter of the oily particles is about 0.05 to 10 mm, preferably about 0.1 to 2 mm, and particularly preferably about 1 mm. Although it differs depending on the scale, it can be prepared by stirring at a rotational speed of about 200 to 1500 rpm using a propeller, a paddle mixer or the like. The oil phase can be introduced into the aqueous phase by, for example, injecting directly from the lower part of the aqueous phase using an injection means such as a liquid feed pump.

In particular, when the specific gravity of the aqueous phase is larger than that of the oil phase, it is preferable to introduce from the lower part of the aqueous phase. In addition, for example, by adding the oil phase to the nozzle, the adjustment of the particle diameter of the oily particles to be formed can be facilitated.
In this way, the desired oily solid particles can be formed in the aqueous phase.

D. The composition for external use The composition for external use is a composition that can be used as, for example, cosmetics (including scalp and hair cosmetics) and skin external preparations, and can be used by coating or the like on the skin of humans or animals. Is possible.

  First, the composition for external use provides a product in the form of an “emulsion in which emulsified particles are visible”, in which fine oily particles are observed in the aqueous phase.

  Further, by using the oily particles in the composition for external use once produced as an element to be added in the production process of a general composition for external use, a composition with various dosage forms and forms can be provided. . That is, these oily particles can be applied to any external composition such as a solution type, a solubilization type, an emulsification system, a powder dispersion system, a water-powder two-phase type, and a water-oil-powder three-phase type. Can be used.

  The product form that the composition for external use can take is also arbitrary, and for example, it can be used as an external composition for facial, body or scalp hair such as lotion, emulsion, cream, pack and the like.

  Next, the present invention will be described more specifically with reference to examples. However, the present invention is not limited to this. In addition, the unit of the following compounding quantity and content is the mass% with respect to a compounding / containing object unless there is particular notice.

○: No aggregation of oily particles is observed, but some turbidity is observed in the outer layer gel.
○ Δ: Almost no aggregation between the oily particles is observed, and some turbidity is observed in the outer gel.
Δ: Aggregation of oily particles to a degree that disperses neatly when shaken is slightly observed, and turbidity is slightly observed in the outer layer gel.
Δ ×: Aggregation that does not disperse easily even when shaken is slightly observed, and some turbidity is observed in the outer layer gel.
X: Oily particles aggregate and turbidity is observed in the outer layer gel.

2) Transparency of outer layer gel The outer layer gel of the test product immediately after production was evaluated by the following criteria by visual observation by one expert panel.

○: Transparent △: Some cloudiness is observed ×: Clearly cloudy

3) Usability (feel after application)
A test product was applied to the forearm of one professional female panel, and the sense of application was evaluated according to the following evaluation criteria.

◎: Not sticky at all and feels refreshing ○: Not sticky at all △: Slightly sticky ×: Pretty sticky

  4) The results of the above test are shown in Table 2 below.

  From this result, it was clarified that by adding a specific solid oil component to the oil phase, it is possible to prevent agglomeration of the oily particles over time and to ensure the transparency of the aqueous phase. It was also found that stickiness during use can be suppressed.

  In addition, it was revealed that it was possible to prevent aggregation of oily particles over time by attaching hydrophilic powder to the surface of oily particles, but some cloudiness of the aqueous phase was observed. . It has also been found that when these two types of means are combined, the usability (feel after application of the product) can be further improved.

[Test Example 5] Examination of UV Scatterer Formulation in Composition for External Use As Example 8, in the formulation of Example 5, the powder component was changed to 0.5% by mass of corn starch (average particle size 8 μm), and fine particles A test article made of titanium oxide (average particle size 0.05 μm) was prepared. However, this fine particle titanium oxide was dispersed in an oil phase component to prepare a test product of Example 8 according to the manufacturing process of Example 5.

  As Example 9, a test product prepared by adding the powder component to 0.5% by mass of corn starch (average particle size 8 μm) and blending fine titanium oxide (average particle size 0.05 μm) in the formulation of Example 5 was prepared. did. However, the corn starch was dispersed in the aqueous phase in the same manner as in Example 5, and the fine titanium oxide was dispersed in the oil phase component, so that the test product of Example 9 was produced according to the production process of Example 5. .

  For these examples, the above 1) evaluation of the state of the particles was carried out. As a result, in both Examples 8 and 9, the fine titanium dioxide powder was dispersed in the oily particles immediately after the preparation of the test product. Over time, in Example 8, aggregation of oily particles was observed. On the other hand, in Example 9, the aggregation of oily particles was not observed over time, and the dispersibility of the fine particle titanium dioxide powder in the particles was maintained.

  Here, although the other formulation examples of this composition for external use are described, all of these formulation examples were stable as a result of said test, and were excellent also in usability. In addition, unless otherwise indicated, the manufacturing method followed the manufacturing method of said Example 1.
