Description

Layered cosmetic product comprising fluorine oil phase

The present invention relates to a layered cosmetic comprising a fluorine-based oil. More specifically, the present invention relates to a layered cosmetic that can increase the dispersibility of the fluorine-based oil in the layered cosmetics containing the fluorine-based oil.

Fluorine-based oils can dissolve a large amount of oxygen due to their ability to use gases, and are used not only as a liquid breathing source for divers and pilots, but also as artificial blood. In addition, fluorine-based oils have good properties as cosmetic ingredients in that they have high water and oil repellency and protect skin from external irritation and have a soft feeling of use. However, in order to use cosmetic ingredients, fluorinated oils are separated from cosmetics mainly composed of oil and water phases because of their lipophibic and hydrophobic properties, and thus contain more than 5% by weight of such fluorinated oils. There was a somewhat difficult point.

As a method for including a large amount of such a substance as a fluorine-based oil in a cosmetic, a layered cosmetic may be introduced. In general, conventional cosmetics are often in a single phase in the form of an emulsion. Layered cosmetics, which are different from single-phase cosmetics, are also possible.Layered cosmetics, unlike single-phase cosmetics, can contain visual differentiation, differentiation in the method of use (shaking just before use), and large amounts of unmixed raw materials. Has the advantage.

However, since layered cosmetics containing a large amount of such fluorine-based oils should be dispersed in the cosmetics immediately before use, the dispersibility of fluorine-based oils in cosmetics should be improved, and stably separated into layers when not in use. This reversible dispersion-separation process must be maintained for the cosmetic shelf life (usually three years).

Therefore, the problem to be solved by the present invention is to improve the dispersibility and stability of the layered cosmetics when using a layered cosmetic containing a fluorine-based oil in order to solve the above problems.

In addition, the problem to be solved by the present invention is to obtain a layered cosmetic that is hypoallergenic to the skin.

In order to solve the above problems, the present invention includes an oil phase layer, an aqueous phase layer and a fluorine oil phase layer, wherein the oil phase layer, the water phase layer, and the fluorine oil phase layer are separated from each other by forming a layer and included in the fluorine oil phase layer. Fluorine-based oils provide layered cosmetics comprising hydrophilic perfluoropolymer liquids.

According to one embodiment of the invention, the fluorine-based oil phase layer may comprise a hydrophilic perfluoropolymer liquid alone, or in addition to the hydrophilic perfluoropolymer liquid a) a fluorocarbon derivative or b) a fluorocarbon derivative and fluoro Furnace may comprise carbon.

Hereinafter, the present invention will be described in detail. The terms or words used in this specification and claims are not to be construed as limiting in their usual or dictionary meanings, and the inventors may appropriately define the concepts of terms in order to best describe their invention. It should be interpreted as meaning and concept corresponding to the technical idea of the present invention based on the principle that the present invention. Therefore, the constitution described in the embodiment described in this specification is only the most preferred embodiment, and does not represent all the technical ideas of the present invention, so that various equivalents and variations And the like.

The present invention includes an oil phase layer, an aqueous phase layer, and a fluorine oil phase layer, wherein the oil phase layer, the water phase layer, and the fluorine oil phase layer are separated from each other by forming a layer, and the fluorine oil included in the fluorine oil layer is a hydrophilic perfluoropolymer. It provides a layered cosmetic comprising a liquid (hydrophilic perfluoropolymer liquid).

In the present invention, the layered cosmetic means a cosmetic in which the components are layered due to two or more unmixed components which are not an emulsion of a single phase. The present invention includes an oil phase layer, an aqueous phase layer, and a fluorine-based oil phase layer, and the three components do not have good affinity with each other, so that the oil phase layer, the aqueous phase layer, and the fluorine-based oil phase layer are not mixed with each other in a static state. It is separated into layers. At this time, the oil phase layer, the water phase layer and the fluorine-based oil phase layer may be changed in order of the layer according to the composition of the cosmetic.

The layered cosmetics including the fluorine-based oily layer are separated from each other in a static state, but in use, the fluorine-based oil is dispersed and applied to the skin as shown in FIG. 1. In general, it should be possible to keep all the fluorine-based oils dispersed in the cosmetics for a longer time than it takes for the consumer to shake the cosmetics and open the lid to apply on the face. In other words, it is necessary to improve the dispersibility of the fluorine-based oil when using the layered cosmetic including the fluorine-based oily layer. At this time, the time it takes for the consumer to shake the cosmetic and then open the lid and apply it to the face is at least 10 seconds, and therefore, in order to have a proper quality as a cosmetic, the separation rate to the layer should be 30 seconds or more. In addition, after shaking, it is separated into layers again as shown in FIG. 2, and in general, after a maximum of 8 hours, it has to be stably separated into the same layers. That is, it is also necessary to improve the stability of the layered formulation so that it can be achieved again.

In addition, the present invention seeks to provide a layered cosmetic that is safe for the skin, which is hypoallergenic to the skin because it is applied directly to the skin as a cosmetic. Accordingly, the inventors of the present invention have a fluorine-based oil included in the fluorine-based oil layer to include a hydrophilic perfluoropolymer liquid. When hydrophilic perfluoropolymer liquid is included in the fluorine-based oil layer, the dispersibility of the fluorine-based oil, the stability of the layered cosmetics, as well as the hypoallergenic, ie, safe cosmetics for the skin can be provided.

The fluorine-based oily layer according to the present invention will be described in more detail.

The fluorine-based oily layer according to the present invention may comprise a) a fluorocarbon derivative or b) a fluorocarbon derivative and a fluorocarbon in addition to hydrophilic perfluoropolymer liquid alone or hydrophilic perfluoropolymer liquid. Fluorocarbon is a compound in which all of the hydrogen in a molecule of a hydrocarbon is replaced with a fluorine atom, and a fluorocarbon derivative is a fluoropolymer, a fluorotelomer, a perfluorinated compound (PFC), Or an organofluorine compound, and the like, but is not limited thereto.

The present invention should include a hydrophilic perfluoropolymer liquid in the fluorine-based oil phase to obtain the improved dispersibility of the fluorine-based oil phase, stability of the layered cosmetics and hypoallergenic cosmetics for the skin according to the present invention. That is, in the present invention, the hydrophilic perfluoropolymer liquid is included for the purpose of improving the dispersibility of the fluorine-based oil phase and improving the stability of the layered cosmetic, and this use is a new use that has not been disclosed in the past.

In the past, attempts were made to increase dispersibility by using ethylperfluorobutyl ether, ethylperfluoroisobutyl ether, ethylperfluoroisobutyl ether, and ethanol in an amount of 30% or more. At this time, the addition of a large amount of ethanol was essential to improve the dispersibility of the fluorine-based oil and to make a stable layered formulation, but there was a problem that irritation is caused to the skin when a large amount of ethanol is used. For example, such cosmetics have a PIR (primary irritation index) of 0.35, that is, light erythema means a safety problem.

The present invention solves this problem by including a hydrophilic perfluoropolymer liquid on the fluorine-based oil.

The hydrophilic perfluoropolymer liquid has a hydroxyl group, an ether group, an amide group, an ester group, a polyethylene glycol group, and a sulfonate group. It may have one or more hydrophilic functional groups selected from the group consisting of sulfonate group carboxyl group and phosphate group.

It means a form of - the polyethylene glycol group refers to _{- (CH 2 CH 2 O)} n.

Alternatively, the hydrophilic perfluoropolymer liquid may be a perfluorohydroxypolymer liquid, a perfluoroetherpolymer liquid, a perfluoroamidepolymer liquid, a perfluoroamide polymer liquid, or a perfluoroester polymer. Perfluoroesterpolymer liquid, perfluoropolyoxyethylene liquid, perfluoropolysulfonate liquid, perfluoropolycarboxylate liquid and perfluoropolyphosphate liquid ( perfluoropolyphosphate) may be one or more selected from the group consisting of.

Or preferably the hydrophilic perfluoropolymer liquid is made of polyperfluoroethoxymethoxy difluorohydroxyethyl ether, polyperfluoroethoxymethoxy difluoroethyl fiji ether ether),

It may be at least one selected from the group consisting of Polyperfluoroethoxymethoxy Difluoromethyl Distearamide and Polyperfluoroethoxymethoxy Difluoromethyl Ether. When the above preferably selected compound is selected, the dispersibility of the fluorine-based oil in the layered cosmetic can be further improved, and the stability of the layered cosmetic can be improved.

The polyperfluoroethoxymethoxy difluorohydroxyethyl ether is represented by the following Chemical Formula 1, and polyperfluoroethoxymethoxy difluoromethyl distearamid is represented by the following Chemical Formula 2, and polyperfluoro Loethoxymethoxy difluoromethyl ether is represented by the following Chemical Formula 3.

In Chemical Formula 1, the average value of p / q is 1, and in Chemical Formula 1, p / q = 0.5 to 3 is preferable.

In Formula 2, RCO means a stearoyl moiety.

According to another embodiment of the invention, the hydrophilic perfluoropolymer liquid may be 0.5 to 90% by weight, preferably 2 to 70% by weight relative to the total weight of the layered cosmetic. If the hydrophilic perfluoropolymer liquid is less than 0.5% by weight of the total weight of the total layered cosmetics, the time required to separate the layered layers after shaking and dispersing the layered cosmetics is shorter than 30 seconds, so that the desired effect cannot be obtained in the present invention. If it is more than%, there is a problem in that the three layers cannot be distinguished because too much fluorine oil phase is added.

In addition, the hydrophilic perfluoropolymer hair may be at least 1% by weight, preferably at least 5% by weight, based on the total weight of the total fluorinated oil layer, and the hydrophilic perfluoropolymer liquid is 0.5 to 90% by weight based on the total weight of the layered cosmetic. If satisfied, the hydrophilic perfluoro polymer may be included as 100%. If the hydrophilic perfluoropolymer liquid is less than 1% by weight of the total weight of the total fluorine-based oil layer, the time required to separate the layered layer after shaking and dispersing the layered cosmetic is short, so that the desired effect is not obtained in the present invention. Even if all consist only of hydrophilic perfluoropolyhydroquine, the mixing-separation of the three layers does not have a significant effect.

The oily phase according to the invention comprises a) an oil or b) an oil and a component which is mixed with an oil phase, the components of which are mixed with the oil and an oil phase, which may be useful in cosmetics.

The oil may be an ester-based oil such as cethylethylhexanoate, neopentyl glycol dicaprate, etc., depending on the structure; Polymeric oils such as polyisobutene, hydrogenated polydecene and the like; Or silicone oils such as dimethicone, phenyltrimethicone, and the like, but are not limited thereto, and are suitable for cosmetic ingredients and are suitable for oil phase.

Or vegetable oils such as macadamia oil, olive oil, lavender oil, etc., depending on their origin; Animal oils such as squalane and the like; Mineral oils such as mineral oils and the like; Or synthetic oils, and the like, but is not limited thereto, and is suitable for cosmetic ingredients and is suitable for oil phase.

In addition to the above examples, it may also include substances mixed in an oil phase at room temperature, for example, cedrol, tocopherol, retinol, and the like, but are not limited thereto. Any suitable material is possible.

The aqueous phase according to the present invention comprises a) water (preferably purified water) or b) water and ingredients to be mixed with water, all of which are useful for cosmetics as the ingredients to be mixed with water and water.

The aqueous phase may be purified water, polyol (e.g. glycerin, 1,2-hexanediol, sorbitol, xylitol, etc.), solution mixed with water (e.g. alcohol, butylene glycol, dipropylene glycol, propylene glycol Lycol, etc.), chelating agents (EDTA-3Na, etc.), pH regulators (AHA, TEA, etc.), water-soluble pigments, polysaccharides (beta-glucan, biosaccharide gums, etc.), water-soluble polymers (carbomer, xanthan) Gum, etc.), electrolytes (NaCl, MgSO _3, etc.), preservatives (phenoxyethanol, etc.), various water-soluble extracts, fermentation products or functional substances (L-hydroxyproline, nicotinamide, etc.) However, the present invention is not limited thereto, and may be any material suitable for cosmetic ingredients and suitable for water phase.

According to another embodiment of the present invention, in particular, the aqueous layer may include sodium chloride (NaCl) or ethanol (ethanol), or may include both sodium chloride and ethanol.

When all of the above sodium chloride is further added, the emulsion produced between layers can be reduced to obtain a cosmetic having a clean interlayer interface. In addition, when ethanol is further added, the affinity between the oil phase and the water phase is increased to remove oil phase droplets between the water phase and the fluorine oil layer, and the interface may be flattened to improve appearance.

For improving the appearance, the content of the ethanol may be 1 to 15% by weight, preferably 5 to 10% by weight of the total weight of the layered cosmetic. If the content is less than 1% by weight, the interface between the aqueous phase and the fluorine oil upper layer is not as clean as in Example 5, but the aesthetic appearance is poor, but there is no big problem in making the layered cosmetics containing the fluorine-based oil. When irritated to the skin may indicate erythema and may also be a problem that can damage the skin barrier causing dryness.

According to another embodiment of the present invention, the oil phase layer, the water phase layer and the fluorine-based oil phase layer is 2 to 90% by weight of the total layered cosmetics. It should be included at least 2% by weight to be able to distinguish the three layers with the naked eye, and if it contains less than it is difficult to identify the three layers with the presence of droplets without a flat layer between the layers and layers. In addition, when more than 90% by weight of each layer alone, the layer is not clearly visible, consumers can recognize as one layer.

Hereinafter, embodiments of the present invention will be described in detail to facilitate understanding of the present invention. However, the embodiments according to the present invention can be modified into various other forms, and the scope of the present invention should not be construed as being limited to the following embodiments. Embodiments of the invention are provided to more fully describe the present invention to those skilled in the art.

<Measurement of Separation Rate of Layered Cosmetics>

According to the components shown in Tables 1 and 2 below, the layered cosmetics of Comparative Examples 1 to 3 and Examples 1 to 6 were prepared. The oil phase, the water phase and the fluorine oil phase were respectively uniformly mixed at room temperature, and each layer was stored by filling the containers with the oil phase, the water phase and the fluorine oil phase in turn. After shaking the layered cosmetics prepared above to disperse the fluorine-based oil phase, the rate of separation into layers or the appearance thereof is shown in Tables 1 and 2 below.

When the hydrophilic perfluoropolymer liquid is not included or contains less, as in Comparative Examples 1 and 2, the separation rate in layers is too short, so that the fluorinated oil may be applied to the skin in a well dispersed state when applied to the skin. If there is too much hydrophilic perfluoropolymer liquid as in Comparative Example 3, there is a problem that it is impossible to distinguish the three layers.

In addition, when compared with Examples 4 and 5, if the cosmetic further comprises sodium chloride (salt), the separation rate is slightly faster, but the interface between the emulsion (see blue square in Figure 3) to reduce the emulsion generated between the clean interface after mixing You can see that you can make Comparing Examples 5 and 6, when ethanol is added to the cosmetics, the affinity between the oil phase and the water phase is increased to eliminate oil droplets between the water phase and the fluorinated oil phase layer (see red circles in FIGS. 3 and 4), Flattening the interface can improve the cosmetic appearance.
