Description

[0001] The present invention relates to an oil-in-water cream type cosmetic composition for filler,

The present invention relates to a filler cosmetic composition for concealing wrinkles and the like, and more particularly to a filler cosmetic composition of the water-in-oil emulsion type containing a high amount of powder.

In general, a filler is a cosmetic used for effectively hiding the wrinkles of the skin and the fine lines of the skin. Specifically, the filler is mainly composed of an oil component such as a wax, an elastomer, a high alcohol, a surfactant, oil and the like and a powder, a moisturizer, a water-dispersible polymer, a skin protecting ingredient, a preservative, a fragrance And the like, and is commercially available.

The above-described filler should have a good feeling of use such as excellent absorption ability, skin adhesion force, skin flexibility, skin protection function, and should not show any change with time such as change of color, discoloration and viscosity as well as skin wrinkle concealment effect.

When the content of the wax and the elastomer in the above components is large, the hardness of the filler is increased and the association of the oil particles is inhibited, so that the stability is improved and the wrinkle concealing effect is further enhanced. However, in such a case, the formulation hardens, the feeling of use becomes heavy, and the dripping property is deteriorated, and wax and high-alcohol components are precipitated at a low temperature with time, and stability may be deteriorated. Further, the phenomenon of abrasion due to the association of the elastomer is seriously manifested and the value as a product is lost.

In order to solve this problem, there is a method of decreasing the content of the elastomer and increasing the content of the powder, but in this case, another problem arises that the formulation can not be stabilized.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a hiding filler cosmetic composition such as a wrinkle which has a reduced jam, a good feeling of use, a high content of powder, and a stability of formulation such as storage stability.

In order to accomplish the above object, the present invention provides a filler cosmetic composition which is a water-in-oil emulsion (cream) characterized by containing a polyethylene glycol (PEG) -containing surfactant and a high content of powder.

The present inventors have made efforts to improve the skin wrinkle concealing effect as well as the formulation stability and at the same time to minimize the jarring phenomenon which occurs in the filler cosmetics containing a large amount of the wax and the elastomer while having the polyethylene glycol (PEG) and the alkyl group It is confirmed that the surfactant stabilizes the silica-coated powder, and when the formulation of the underwater type emulsion (cream) contains a high amount of the powder relative to the silicone elastomer, the jamming phenomenon can be minimized by the interaction with the polyethylene glycol Thereby completing the present invention.

In the case of filler cosmetics containing a large amount of wax and elastomer, the shrinkage phenomenon appears to be serious. Therefore, a method of increasing the content of the elastomer and reducing the content of the elastomer is proposed as a method to prevent this phenomenon. The polyethylene glycol (PEG) The present inventors have found that the use of a surfactant having a hydrophilic property improves the concealing effect of skin wrinkles and improves the problem of precipitation of wax at a low temperature and separation of contents at a high temperature in a high- It is possible to provide a wrinkle concealed filler cosmetic composition having a satisfactory stability, thereby completing the present invention.

The filler cosmetic composition according to the present invention contains the powder in a high content and is generally 3 to 30% by weight based on the total weight of the composition, preferably 15% by weight or more, more preferably 20% %, Even more preferably from 20 to 30 wt%.

In the filler cosmetic composition of the present invention, the above-mentioned powders may be used alone or in combination, such as HS diethyl ether / triethyl oleyl lactone cross polymer, nylon-12, boron nitride, silica and polymethylsilsesquioxane. , HS diethyl / triethyl oleyl lactone crosspolymer are preferred for various purposes of the present invention.

The underwater type cream type filler cosmetic composition of the present invention comprises a PEG-containing, preferably PEG and alkyl group containing 8 to 22 carbon atoms, surfactant.

Such PEG-containing surfactants include glyceryl monostearate, glyceryl stearate / PEG-100 stearate, PEG-4 stearate, PEG-6 stearate, PEG-12 stearate, PEG- 32 stearate PEG-40 stearate, PEG-75 stearate, PEG-150 stearate, polysorbate 20, polysorbate 40, polysorbate 60 and polysorbate 80 may be used alone or in combination .

As the PEG and alkyl group-containing surfactants, for example, compounds of the following formula may be used, but are not limited thereto.

Also, the content of the PEG and alkyl group-containing surfactant is 1 to 5% by weight based on the total weight of the cosmetic composition; Feeling of use such as excellent absorbency, skin adhesion, and skin flexibility; And from the viewpoint of minimizing the jarring phenomenon, more preferably from 2 to 3% by weight.

At this time, if the content of the surfactant is less than 1 wt%, it does not greatly improve the stability of the powder at high temperature, and if it exceeds 5 wt%, the soft appearance, which is one of the important qualities of the emulsion, becomes rough. In addition, when the structural characteristic of the alkyl group is polygonal (pulverized) rather than linear, the function of the emulsion is improved by further influencing the stability of the powder when the product is applied. This is because the hydrogen bond between silica (SiO ₂ ) and polyethylene glycol (PEG) surfactant coated on the surface of the powder stabilizes the powder, and in the case of a polygonal surfactant, it has a stereostructure similar to the spherical powder Which is believed to result in a more stable emulsification system in the formulation.

More preferably, the filler cosmetic composition according to the present invention is an underwater type cream type composition comprising 20-90% by weight of an aqueous phase composition containing purified water and a moisturizer, 1-30% by weight of powder, 1-10% by weight of wax, 1 to 10% by weight of butter, 1 to 30% by weight of silicone oil, and 1 to 5% by weight of a surfactant containing polyethylene glycol (PEG).

Most of the ingredients of the water are moisturizing agents such as purified water and glycerin, and water-soluble preservatives, fragrance, xanthan gum, trisodium iodide and the like may be included in the water phase. The oil component may include wax, butter, oil, lipophilic polymer, lipophilic surfactant, and the like.

That is, the underwater type cosmetic composition of the present invention may contain a humectant, a high alcohol, an oil, a wax, a purified water, various additives, and the like, which are included in a normal emulsion composition, Can be used. It goes without saying that the content range of each of the above components may be used within the usual range as long as the object of the present invention is not impaired.

For example, the wax is a solid component that maintains the appearance of the emulsion and can be used alone or in combination with candelilla lead, ceresin, carnauba wax, paraffin wax, wood wax, beeswax, beeswax, microcrystalline wax, Provides gloss to the surface, protects the skin by forming a protective film when used on the skin, and increases the feeling of use.

The higher alcohol is a solid component having the greatest influence on the viscosity of the emulsion, and may be used alone or in combination with cetyl alcohol, stearyl alcohol, behenyl alcohol, myristyl alcohol, etc., Thereby inhibiting the association and improving the stability of the formulation.

The oil may be a liquid oily component such as oil extracted from plants and animals such as castor oil, jojoba oil and squalane, synthetic ester oil and silicone oil. In addition, the oil dissolves solid components such as wax and higher alcohol, affects the adhesion and spreadability of the emulsion, and serves as a factor influencing the feel and stability of the emulsion depending on the content and selection of the oil component.

As the moisturizing agent, water-soluble components such as glycerin, butylene glycol, propylene glycol, dipropylene glycol, hyaluronic acid, and betaine can be used. The moisturizing agent enhances the moisturizing ability of the skin and lowers the polarity of the water, so that the wax having a low polarity, the higher alcohol, and the surfactant interact with the water phase to affect the stability of the emulsion.

In addition, the present invention can use various additives such as preservatives, fragrance, etc., which are used in common cosmetic compositions, and the content range thereof is not particularly limited.

In addition, the purified water is contained in the remaining amount in the filler cosmetic composition of the water-in-oil type (cream) type according to the present invention, and the content thereof can be used to control the final viscosity.

The filler cosmetic composition according to the present invention has a hardness of 60 to 200 dyne / cm ² , which is relatively harder than the conventional ones, has excellent wrinkle concealing effect and absorption power, and does not show separation of powder at high temperature.

The present invention uses a surfactant having polyethylene glycol and an alkyl group to prevent jumping phenomenon and stabilize the powder even when a high amount of powder is used in an emulsion, and has excellent feeling of use such as excellent absorbency, skin adhesion and skin flexibility An oil-in-water emulsion-type filler cosmetic composition excellent in wrinkle hiding effect, which is improved in formulation stability and improved in problems such as precipitation of wax at low temperature and separation of contents at high temperature.

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.
