Description

Oil-free makeup cosmetic composition containing water dispersion binder and powder mixture}

The present invention relates to an oil-free makeup cosmetic composition, and more particularly, to a liquid phase such as a foundation or a makeup base by mixing a coating / uncoated powder mixture with an aqueous dispersion binder composed of water, a polyol and a thickener. It relates to an oil-free makeup cosmetic composition prepared with a formulation that is oil-free and has a cosmetic-like cosmetic effect.

Foundations and makeup bases that are commonly used are emulsified formulations such as O / W, W / O, and W / S. Because they have a structure in which oil and water form an interfacial shape, they have good adhesion and durability, while they are heavy due to oil components. It has a sticky feeling. In the case of the O / W structure where water forms the outside of the interface, the oil has a relatively less oil feel and provides moisture than the W / O outside the interface, but the oil has a heavy and sticky finish. In addition, the foundation and make-up bases are less bright than general powders such as powder pacts, two-way cakes and powder powders. In the case of powders, diffuse reflection is induced by spherical powder contained therein to maximize the brightness. This is because the content of such spherical powder is limited in emulsions. In addition, if you use only powdered products, it is not cumbersome because it does not adhere well to the skin or has low sustainability, so it is not only cumbersome but also mainly made up of powder. For this reason, most female customers apply basic makeup for skin contact, and then apply foundation or makeup base and apply powder to express brightness. This has caused inconvenience and inconvenience for customers who want simple makeup.

Recently, a new category of BB cream has come out and provides various effects at once, but there is a limit to brightening the skin with a large amount of oil and a small amount of powder.

Accordingly, the present inventors have tried to prepare a makeup cosmetic composition that can be easily makeup while maximizing the brightness, as a result, mixing the coating / uncoated powder mixture in a predetermined ratio to the water-dispersed binder consisting of water, polyols and thickeners without using oil In this case, by having a liquid formulation such as existing emulsions (foundation, makeup base, BB cream, etc.), it has excellent adhesion and lasting power, and is not heavy or sticky, thus providing a feeling of use and producing a cosmetic composition for bright skin. It has been found that the present invention has been completed.

Accordingly, an object of the present invention is to provide an oil-free makeup cosmetic composition having excellent adhesion and sustainability and ensuring a feeling of use, such as lightness and lightness.

In order to achieve the above object, in the present invention, 1) a water-dispersed binder consisting of water, polyols and thickeners; and 2) a coating and uncoated powder mixture; the makeup cosmetic composition is mixed in a weight ratio of 7: 3 to 5: 5 To provide.

The makeup cosmetic composition according to the present invention has excellent adhesion and lasting power and is not only heavy or sticky, but also has excellent feeling and bright skin expression.

The present invention

1) an aqueous dispersion binder composed of water, a polyol and a thickener; and

2) coated and uncoated powder mixtures;

This relates to a makeup cosmetic composition mixed at a weight ratio of 7: 3 to 5: 5. In this case, when the content of the water-dispersing binder is higher than the mixing ratio, the bright effect due to the low viscosity and powder is reduced, and when the content is smaller than the mixing ratio, the viscosity increases, so as to increase the viscosity and decrease the coating amount.

At this time, the water dispersion binder and the powder is preferably mixed using a universal mixer (KENWOOD KMC400), not a general Henschel mixer.

Water dispersion binder used in the present invention is composed of water, polyols and thickeners, 0 to 50% by weight of the polyol, 0.1 to 1% by weight of the thickener and the remaining amount of water to the total weight of the binder by mixing 10 minutes or more with an azi mixer It can manufacture. At this time, the content of the polyol is limited to a maximum of 50% by weight, because if it exceeds 50% by weight, the stickiness is increased and the viscosity is increased to lower the formulation stability.

Polyol (polyol) used in the present invention is glycerin, Dipropylene Glycol, sorbitol solution (Sorbitol solvent), Glycerol (Glycerol), polyethylene glycol, propylene glycol (Propylene Glycol) and 1,3- At least one selected from the group consisting of butylene glycol (1,3-Butylene Glycol) may be used, and it is preferable to use a mixture of glycerin and 1,3-butylene glycol, wherein the content of glycerin is water 0 to 50% by weight based on the total weight of the dispersed binder is preferred.

The thickener used in the present invention is composed of Keltrol-F, Bentonite, Hydroxy Ethyl Cellulose, Xanthan Gum, and Carboxyl Methyl Cellulose. One or more kinds selected from the group can be used, and Keltrof is preferably used.

The coating / uncoated powder mixture used in the present invention is a mixture of the coating powder and the uncoated powder.

Coating powder used in the present invention is 25 to 90% by weight of the coated plate powder, 0 to 20% by weight titanium dioxide, 0 to 5% by weight zinc oxide (Zinc oxide) and 10 to 50% by weight silica It consists of. When the content of the titanium dioxide exceeds 20% by weight, the turbidity is increased and the feeling of use is deteriorated. When the content of zinc oxide is more than 5% by weight, the heavy feeling of use is highlighted as a disadvantage, and the content of the silica is increased. If it is less than 10% by weight, it is difficult to formulate, and if it is more than 50% by weight, the adhesion and coverage are low. The coating material used for the powder coating may include methicone, dimethicone or alkylsilane, and the amount of the coating material is 0.5 to 3 based on the total weight of each coated material. Weight percent is preferred. This is to prevent the initial agglomeration between the binder and the powder and to achieve complete dispersion when the powder coated with silicone is mixed with the dispersing binder. The plate-shaped powder may use a raw material such as talc, mica, sericite, barium sulfate, boron nitride, or alumina.

The uncoated powder used in the present invention is composed of 5 to 30% by weight silica and pigments based on the total weight of the powder mixture.

The makeup cosmetic composition according to the present invention is characterized in that the liquid formulation similar to the foundation or the makeup base or the feeling of use and the purpose of use, unlike the foundation or the makeup base, has excellent adhesion and durability and a heavy or non-stick feeling.

Hereinafter, the content of the present invention will be described in more detail through examples and test examples. These examples are provided only for understanding the contents of the present invention, and the scope of the present invention is not limited to these examples, and modifications, substitutions, and insertions commonly known in the art may be performed. This is also included in the scope of the present invention.
