Technical Field

The present invention relates to a water-in-oil type cosmetic composition for preventing syneresis, and a water-in-oil type cosmetic.

Background

At present, in cosmetic compositions, from oil-in-water compositions to water-in-oil compositions are widely used. For example, in the case of Sun Protection, in order to block ultraviolet irradiation to the skin and obtain a high SPF (Sun Protection Factor) value, an ultraviolet absorber or an ultraviolet scattering agent (zinc oxide, titanium dioxide, or the like) is blended in the cosmetic. Since a cosmetic including such a sunscreen cosmetic is required to have a feeling of use of moisture, an oil-in-water (hereinafter, also referred to as O/W) type cosmetic is increasing. On the other hand, water-in-oil (hereinafter, also referred to as W/O.) type creams are preferable from the viewpoint of the method of use and the covering power.

However, in the W/O type cream, the risk of syneresis (oil separation) with time is high, and a method for preventing such a phenomenon is not completely elucidated.

For example, a water-in-oil emulsion cosmetic composition containing (a) 0.5 to 10 mass% of an alkyl-modified silicone, (B) 0.1 to 10 mass% of a cross-linked organopolysiloxane polymer, (C) 0.1 to 10 mass% of dimethiconol, (D) 1 to 20 mass% of a polyol, and (E) 5.0 to 60.0 mass% of water is known to have excellent long-lasting property and emulsion stability, and particularly, have extremely excellent stability such that a bleeding phenomenon of an external oil phase does not occur even in a tube container or the like (patent document 1).

In such patent document 1, the blending of the organically modified clay mineral and the hydrophobized silica is generally an effective method because the gel can be gelled, thickened and stabilized regardless of the kind and properties of the oil phase, but the method may be accompanied by conditions in which the formation of the gel structure is slowly completed, the phenomenon of Syneresis (Syneresis) described above may occur over a long period of time, and the bleeding of the oil may be observed after several months or 1 year in the final stage of the accelerated test period, and therefore the technique of patent document 1 is intended to solve the problem of the bleeding phenomenon of the external oil phase by using an alkyl modified silicone or the like without using the organically modified clay mineral.

Disclosure of Invention

Problems to be solved by the invention

However, although the mechanism of the water-in-oil type composition has been continuously studied for years, the main cause has not yet been elucidated. It is desired to solve the phenomenon of syneresis and the like. The syneresis is caused by, for example, only the oil component or the like flowing out of a composition in which the upper layer is composed of oil and the lower layer is composed of powder and emulsified particles. When used, the composition is used by shaking or the like, but sometimes the syneresis occurs immediately or takes several days. In many cases, it is considered that the problem of syneresis is caused by the possibility of containing different substances such as water, oil, and powder. Thus, it is desirable to obtain the composition as a monolayer, but such compositions have not been known to date. Further, the use of a gelling agent is advantageous in that it can provide a moist feeling in use, and therefore, a cosmetic material which can prevent syneresis and the like and exhibit good stability even when the gelling agent is used is desired if possible.

However, including patent document 1, a cosmetic composition, a cosmetic, and the like which have been conventionally used to prevent syneresis and exhibit good stability have not been available.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a water-in-oil type cosmetic composition and the like which exhibit good stability by preventing syneresis and the like.

Means for solving the problems

ADVANTAGEOUS EFFECTS OF INVENTION

According to the water-in-oil cosmetic composition and the water-in-oil cosmetic for preventing syneresis of the present invention, when used from a container or the like, the advantageous effect of preventing syneresis such as coming out of oil and causing discomfort is exhibited.

Detailed Description

The water-in-oil type cosmetic composition for preventing syneresis of the present invention contains a compound solubilized by neutralization as an active ingredient. In the present invention, the compound that is water-soluble by neutralization is not particularly limited as long as it can prevent syneresis of the water-in-oil type cosmetic composition. This is because, in the course of a series of studies on sunscreen products, the present inventors have found that syneresis occurs in W/O creams, and in the course of improvement studies to solve the syneresis, the syneresis of W/O creams can be prevented by a compound that is water-soluble by neutralization, particularly a water-soluble compound having a sulfonic acid group.

In the present invention, in order to prevent syneresis of the water-in-oil type cosmetic composition, it suffices to include an effective amount, and the amount of the compound to be water-solubilized by neutralization may be appropriately set.

Further, in a preferred embodiment of the water-in-oil cosmetic composition for preventing syneresis of the present invention, the above-mentioned compound solubilized in water by neutralization may contain a compound having a sulfonic acid group. Examples of the compound having a sulfonic acid group include at least 1 selected from phenylbenzimidazole sulfonic acid, terephthalylidene dicamphor sulfonic acid, and ammonium (acryloyldimethyltaurate/VP) copolymer. In the present invention, examples of the compound having a sulfonic acid group include phenylbenzimidazole sulfonic acid and p-xylylene dicamphor sulfonic acid. In the water-in-oil type cosmetic composition for preventing syneresis of the present invention, from the viewpoint of being cream-like, when the viscosity of the composition is 7000mPa · s or more, the effect of preventing syneresis can be particularly exhibited. In the present invention, the following measurement apparatus and measurement conditions can be used for measuring the viscosity of the composition or the cosmetic.

A measuring device: zhipu \12471model, 12473 テム, model B viscometer, model VDA2

The measurement conditions were as follows: 12rpm 1 min 30 deg.C

The water-in-oil cosmetic of the present invention is characterized by containing a compound which is water-soluble by neutralization, a gelling agent, water, and a powder component, and by having a viscosity of 7000 mPas or more.

In the present invention, the compound that is water-soluble by neutralization is not particularly limited, and from the viewpoint of preventing syneresis, a water-soluble compound having a sulfonic acid group is preferably used. Examples of the water-soluble compound having a sulfonic acid group include phenylbenzimidazole sulfonic acid, terephthalylidene dicamphor sulfonic acid, and ammonium (acryloyldimethyltaurate/VP) copolymer. The water-soluble compound having a sulfonic acid group preferably includes at least 1 selected from phenylbenzimidazole sulfonic acid, terephthalylidene dicamphor sulfonic acid, and ammonium (acryloyldimethyltaurate/VP) copolymer. These may be used alone or in combination of two or more.

From the viewpoint of preventing syneresis, the amount of the compound having a sulfonic acid group may be 0.01 to 5% by mass, and more preferably 0.1 to 3% by mass, based on the total amount of the water-in-oil cosmetic. Such a range is because if it is less than 0.01, no effect may be produced, and if it exceeds 5, precipitation and crystallization may occur.

In the present invention, particularly, when the compound which is water-soluble by neutralization is a water-soluble UV absorber, the water-in-oil type cosmetic of the present invention can be used as a sunscreen cosmetic. In this case, the water-soluble compound is more preferably contained in an amount of 0.1 to 5% by mass so as to absorb ultraviolet rays in a wider range. When the content of the water-soluble compound is less than 0.1% by mass, the effect of preventing ultraviolet rays cannot be sufficiently exhibited, and when it is more than 5% by mass, stickiness occurs, incomplete dissolution occurs, and crystals precipitate, which is not preferable.

In the present invention, the gelling agent is not particularly limited. Examples of the gelling agent include oily gelling agents such as dextrin fatty acid esters, sucrose fatty acid esters, organically modified clay minerals, 12-hydroxystearic acid, and metal soaps. In the present invention, the gelling agent may be a clay mineral, and further an organically modified clay mineral, from the viewpoint that a thickening effect can be obtained in a small amount. Examples of the organically modified clay mineral include distearyldimethylammonium hectorite, dimethylalkylammonium hectorite, benzyldimethylstearylammonium hectorite, distearyldimethylammonium chloride-treated aluminum magnesium silicate, and the like. As commercially available products, ベントン 27 (benzyldimethylstearylammonium chloride-treated hectorite, manufactured by ナショナルレッド) and ベントン 38 (distearyldimethylammonium chloride-treated hectorite, manufactured by ナショナルレッド) can be preferably used.

In the present invention, the clay mineral including these organically modified clay minerals may be incorporated in an amount of 0.01 to 2.0% by mass, and more preferably 0.5 to 2.0% by mass, based on the total amount of the water-in-oil type cosmetic. If the amount is less than 0.01% by mass, sufficient stability is not easily obtained, and a use feeling of moisture can be obtained by blending not more than 2.0% by mass, and if the amount exceeds this amount, the grip property of the fingers is deteriorated, and the extensibility on the skin is increased, which is not preferable in terms of use.

The powder component is not particularly limited as long as it can be used in a water-in-oil emulsion type powder component. Examples of the powder component include inorganic powders such as talc, mica, kaolin, mica, sericite (serite), muscovite, phlogopite, synthetic mica, lepidolite, biotite, lepidolite, vermiculite, magnesium carbonate, calcium carbonate, aluminum silicate, barium silicate, calcium silicate, magnesium silicate, strontium silicate, metal tungstate, magnesium, spherical silica, zeolite, barium sulfate, calcined calcium sulfate (calcined gypsum), calcium phosphate, fluorapatite, hydroxyapatite, ceramic powder, metal soap (zinc myristate, calcium palmitate, aluminum stearate, etc.), boron nitride, etc.; spherical organic powders such as polyamide spherical resin powder (nylon spherical powder), spherical polyethylene, crosslinked polymethyl (meth) acrylate spherical resin powder, spherical polyester, crosslinked polystyrene spherical resin powder, spherical resin powder of a copolymer of styrene and acrylic acid, benzoguanamine spherical resin powder, polytetrafluoroethylene spherical powder, and spherical cellulose; inorganic white pigments such as zinc oxide, titanium oxide, barium sulfate, and zinc oxide coated or compounded with silicic anhydride; inorganic red pigments such as iron oxide (red iron oxide) and iron titanate; inorganic brown pigments such as gamma-iron oxide; inorganic yellow pigments such as yellow iron oxide and yellow soil; inorganic black pigments such as black iron oxide, carbon black and titanium suboxide; inorganic violet pigments such as manganese violet and cobalt violet; inorganic green pigments such as chromium oxide, chromium hydroxide, and cobalt titanate; inorganic blue pigments such as ultramarine blue and navy blue; mica titanium, iron oxide red-coated mica titanium, carmine-coated mica titanium, navy blue-coated mica titanium, titanium oxide-coated synthetic phlogopite, iron oxide red/titanium oxide-coated synthetic phlogopite, titanium oxide-coated glass flake, iron oxide red/titanium oxide-coated glass flake, titanium oxide-coated alumina flake, titanium oxide-coated silica flake, iron oxide/silica-coated aluminum, iron oxide/silica-coated iron oxide, metal-coated plate powder, polyethylene terephthalate/polymethyl methacrylate laminated film powder (which may contain a coloring material), polyethylene terephthalate/polyolefin laminated film powder (which may contain a coloring material), epoxy resin-coated aluminum-deposited polyethylene terephthalate (which may contain a coloring material), aluminum-deposited polyethylene terephthalate (which may contain a coloring material), Urethane resin-coated aluminum vapor deposition polyethylene terephthalate (may contain a coloring material), acrylic resin-coated aluminum powder (may contain a coloring material), titanium oxide-coated mica, titanium oxide-coated bismuth oxychloride, titanium oxide-coated talc, colored titanium oxide-coated mica, bismuth oxychloride, fish scale foil, and other pearlizing/glittering agents. Preferred examples thereof include titanium oxide, zinc oxide, talc, polymethylsilsesquioxane, a methyl methacrylate crosslinked polymer, iron oxide, and spherical polyalkyl acrylate. These may be used alone or in combination of two or more.

From the viewpoint of usability, these powder components may be blended in an amount of 1 to 40% by mass based on the total amount of the water-in-oil type cosmetic. If the amount is less than 1, the tackiness may be deteriorated, and if the amount exceeds 40 mass%, the extensibility may be increased, and the wettability may be lowered, thereby deteriorating the usability.

In addition, both hydrophilic and hydrophobic powder components are exemplified as described above, but from the viewpoint of water resistance, examples of the powder components include hydrophobic powder components such as titanium oxide, zinc oxide, talc, iron oxide, spherical polyalkyl acrylate, (meth) acrylate resin powder, polyamide resin powder (nylon powder), polyethylene powder, polystyrene powder, copolymer resin powder of styrene and (meth) acrylic acid, benzoguanamine resin powder, polytetrafluoroethylene powder, cellulose powder, and polymethylsilsesquioxane powder, and organopolysiloxane elastomer spherical powder or composite spherical powder using the same as a matrix powder.

In a preferred embodiment of the water-in-oil cosmetic of the present invention, the mass ratio of the compound solubilized in water by neutralization to the water is 0.02 or more from the viewpoint of preventing syneresis. If the above mass ratio is less than 0.02, syneresis may occur.

In a preferred embodiment of the water-in-oil cosmetic of the present invention, the mass ratio of the gelling agent to the powder component is 0.1 or less from the viewpoint of usability. If the mass ratio is 0.1 or more, the extensibility on the skin may be increased, and the skin may not be moistened, thereby impairing the usability.

In a preferred embodiment of the water-in-oil cosmetic of the present invention, the cosmetic further contains an emulsifier from the viewpoint of preventing syneresis. The emulsifier is also not particularly limited. Examples of the emulsifier include silicone surfactants, glycerin fatty acid esters, polyglycerin fatty acid esters, polyoxyethylene glycerin fatty acid esters, sorbitan fatty acid esters, and polyoxyethylene sorbitan fatty acid esters, and among them, silicone surfactants are preferable from the viewpoint of preventing syneresis.

The silicone surfactant is not particularly limited as long as it can be used in a water-in-oil emulsion type silicone surfactant, and examples thereof include a poly (oxyethylene/oxypropylene) methyl polysiloxane copolymer, a polyoxyethylene methyl polysiloxane copolymer, a silicone chain branched methyl polysiloxane copolymer, an alkyl chain branched polyoxyethylene methyl polysiloxane copolymer, an alkyl chain/silicone chain branched polyoxyethylene methyl polysiloxane copolymer, a crosslinked polyoxyethylene methyl polysiloxane containing an alkyl group, a branched polyglycerol-modified silicone, a crosslinked polyglycerol-modified silicone containing an alkyl group, and an alkyl branched polyglycerol-modified silicone.

From the viewpoint of emulsion stability, the silicone surfactant preferably includes lauryl PEG-9 dimethiconoethyl dimethicone, PEG-10 dimethicone, dibutyl dimethicone polyglyceryl-3, cetyl PEG/PPG-10/1 dimethicone, PEG-12 dimethicone, dimethicone/(PEG-10/15)) crosspolymer, (dimethicone/polyglyceryl-3) crosspolymer, and (PEG-15/lauryl dimethicone ethyl dimethicone) crosspolymer.

From the viewpoint of emulsion stability, these emulsifiers may be incorporated in an amount of 0.1 to 10% by mass based on the total amount of the water-in-oil cosmetic. This range is because if it is less than 0.1, syneresis may not be prevented, and if it exceeds 10, extensibility on the skin may become thick, and usability may be impaired such as no longer being moistened.

In the water-in-oil cosmetic of the present invention, other components than the above-mentioned components may be appropriately blended as necessary as long as the object and effect of the present invention are not impaired. Examples of such components include water-soluble polymers, oil-soluble polymers, polymer powders, waxes, alcohols, liquid oils and fats, ester oils, hydrocarbon oils, silicone oils, fatty acids, higher alcohols, fatty acid esters, drugs, ultraviolet absorbers (other than those described above), and ultraviolet scattering agents.
