Description

TECHNICAL FIELD The present invention relates to a cosmetic composition containing a powder and a method for producing the same,

The present invention relates to a cosmetic composition comprising a powder, which is excellent in moldability and a method for producing the same.

The cosmetic composition such as make-up contains a powder component as a base component. Examples of such powder components include nylon, silica, and silicone-based powder. In addition, the cosmetic composition comprises a binder which binds the powder component for formulation.

The powder cosmetic composition generally can be classified into a press formulation and a cream formulation. The conventional powder cosmetic composition has the following problems according to the formulation. In the case of press formulations, there are disadvantages such as flaking, color persistence, and molding stability. In the case of the cream formulation, although it has the advantage of soft spreadability, it has a disadvantage that the skin adhesion is poor and the feeling of use is greasy.

In addition, the conventional powder cosmetic composition has a problem that its content is limited when a spherical powder such as silica is used for feeling as a powder. For example, when the content of spherical powder is maximized in a press formulation, it is difficult to exhibit a desired level of molding strength due to the repulsive force between spherical powder particles and the large size of spherical powder particles.

On the other hand, a method of using an excess amount of oil or wax as a binder may be considered for moldability, but in this case, a caking phenomenon occurs, and the use feeling of the cosmetic material is considerably lowered.

In order to overcome the disadvantages described above, attempts have been made to mix a thickening agent and a volatile solvent in addition to the oil as a binder. However, in this case, there is a difficulty in formulation due to compatibility between the powder and the binder, The problem of improvement still remains.

The cosmetic composition according to one embodiment of the present invention comprises

(1) preparing an emulsion binder comprising at least one oil component selected from waxes, oils and surfactants and starch; And

(2) mixing the powder component, the acrylic polymer and the emulsion binder.

As an embodiment of the present invention, the emulsion binder prepared in the step (1) of producing the emulsion binder may be used as a binder for binding the powder component of the cosmetic composition, . Hereinafter, a method for producing an emulsion binder according to the present invention will be described.

According to one embodiment of the present invention, the emulsion binder comprises

(a) preparing an aqueous phase;

(b) obtaining an oily phase comprising at least one oil component selected from waxes, oils and surfactants and starch;

(c) mixing the water and the oil phase to emulsify the emulsion; And

(d) stabilizing the emulsified emulsion. < Desc / Clms Page number 12 >

The water phase of step (a) may include water, and may further include a moisturizing agent. Specifically, in step (a), water and a humectant may be mixed with water and a humectant, and then heated to produce a water-pervious part. When the water and the moisturizing agent are mixed and heated, the humectant may be uniformly dissolved in water. In this case, the heating temperature may be 60 to 90 ° C, more specifically 70 to 80 ° C. If the heating temperature is lower than 60 ° C, it may be difficult to uniformly dissolve, and if it exceeds 90 ° C, water may be volatilized. In addition, the humectant may include a polyol, and the specific kind of the polyol is as described above.

The step (b) may be carried out by mixing at least one oil component selected from waxes, oils and surfactants and starch, followed by heating to produce an oily phase. Specific examples of the wax, oil, surfactant and starch are as described above. At this time, heating can also be performed when the oil phase component and the starch are mixed. In this case, the oil phase component and the starch can be mixed more effectively. The heating temperature may be the same as or similar to the temperature of the water receiving portion, for example, from 40 to 100 캜, more specifically from 60 to 90 캜 or from 70 to 80 캜. If the heating temperature is lower than 40 ° C, it may be difficult to uniformly mix. If the heating temperature is higher than 100 ° C, volatilization of the oil component may occur.

In the step (c), an oil phase may be added to the upper part of the water, or the water phase may be added to the oil phase, followed by emulsification through stirring. At this time, when the water phase and the oil phase are mixed, other additional components may be added. The additional components include functional ingredients and additives such as, for example, emulsifiers, emulsion stabilizers, thickeners, antioxidants, sunscreens, pigments, perfumes and preservatives. The specific kind of these additional ingredients is not limited. The additional components may be first mixed into the oil phase, and then mixed and emulsified with the water phase.

In the step (c), that is, in the emulsion mixing process of the water phase and the oil phase, heating may be carried out so as to have a uniform emulsion form, and the heating temperature may be 60 to 90 ° C, more specifically 70 to 80 ° C. If the heating temperature is lower than 60 ° C, uniform emulsification may be difficult, and if it exceeds 90 ° C, water may be volatilized.

In the step (c), as described above, the upper part and the upper part may be mixed in an amount of 5 to 60 parts by weight based on 40 to 95 parts by weight of the water, and more specifically, 10 to 40 parts by weight of the oil phase, and 20 to 30 parts by weight of the oil phase relative to 70 to 80 parts by weight of the water. The specific mixing ratio of the moisturizing agent, the oily component, the starch and the acrylic polymer may be adjusted to the above-mentioned contents based on the total weight of the emulsion binder.

The step (d) may include stabilizing the emulsion obtained by emulsifying in the step (c), which may be carried out, for example, by allowing to stand at room temperature or cooling. Specifically, emulsifying the emulsified emulsion at 25 to 50 ° C, 45 ° C, or 35 ° C to 40 ° C.

As one embodiment of the present invention, the specific kinds and contents of the powder component and the acrylic polymer used in the step (2) are as described above.

In addition, the step (2) may further include functional ingredients and additives commonly used in the art such as flavorings, preservatives, pigments, solvents, thickeners, ultraviolet screening agents and antioxidants. The specific kinds of these functional components and additives are not limited.

As another embodiment of the present invention, the step (2) may be carried out by using a cross-linked acrylic acid ester, an acrylate / bis-hydroxypropyl dimethicone crosspolymer, an acrylate / C10-30 alkyl acrylate, an acrylate / 13 alkyl methacrylate / methoxyethyl acrylate crosspolymer, ethylhexyl acrylate crosspolymer, acrylate / ethylhexyl acrylate crosspolymer, acrylate / lauryl methacrylate / tridecyl methacrylate crosspolymer, acrylate / PEG-4 dimethacrylate crosspolymer, an acrylate / rhus vernicifluas crosspolymer, an acrylate / stearate-20 methacrylate crosspolymer, an acrylate / VA crosspolymer, an acrylate / vinylisodicanoate crosspolymer , Acrylate / vinyl neodicanoate < RTI ID = 0.0 > And the like, and the specific content thereof is as described above.

Also, as an embodiment of the present invention, the step (2)

Mixing the powder component, the acrylic polymer and the emulsion binder, and stirring the mixture;

Secondarily stirring the first stirred mixture; and

And a water removing step of drying the secondary agitated mixture to remove water contained in the mixture.

At this time, the secondary stirring can be performed at a higher speed than the primary stirring. Specifically, the powder component, the acrylic polymer, and the emulsion binder are mixed and stirred at a low speed first, . At this time, the powder component is slowly wetted to the acrylic polymer and the emulsion binder by the first low-speed stirring, and uniform mixing is carried out by secondary high-speed stirring, thereby stabilizing the formulation of the cosmetic.

More specifically, when mixing with an emulsion binder, a high viscosity mixer can be used from the viewpoint of minimizing the loss of the powder component. At this time, the powder component was first put into the high viscosity mixer, and then the emulsion binder was added to the emulsion binder in accordance with the content ratio. Then, the powder component was slowly wetted to the acrylic polymer and emulsion binder by primary stirring (low speed stirring) Speed stirring) to complete the formulation.

The primary and secondary stirring speeds are not limited, but the primary stirring can be performed at a speed of, for example, 100 rpm to 800 rpm. If the speed is less than 100 rpm, the agitation time becomes excessively long. If the speed is more than 800 rpm, a problem such as a powder component is generated, and thus, a formulation variation easily occurs. The secondary stirring (high-speed stirring) is not particularly limited, but can be carried out at a speed of 1,000 rpm to 5,000 rpm. The emulsion binder composition, the acrylic polymer, and the powder component can be sufficiently mixed within the above-mentioned speed range.

In addition, the primary and secondary agitation times are not limited, but the primary agitation can proceed for 30 seconds to 5 minutes from the viewpoint that the powder is wetted, and the secondary agitation causes the emulsion binder to be evenly mixed with the powder ingredients , For 2 minutes to 20 minutes, preferably 5 minutes to 10 minutes.

In addition, the method of manufacturing a cosmetic composition according to an embodiment of the present invention may further include a water removing step of removing water in the mixture after the mixing step (2). In the step (2), water is contained in the mixture, and water can be removed by volatilizing the water. This moisture removing step is an additional step that is carried out as needed. This is a step that is required to formulate products such as cosmetic products requiring high viscosity, such as solid cosmetics (powder products) and makeups (color products, eye shadow, mascara etc.) Can proceed.

The above water removal does not only mean the complete removal of water (water) from the mixture but also includes removing a certain amount of moisture to have a higher viscosity than the mixture obtained in the step (2). The water removal step may be realized by, for example, allowing the water to evaporate through leaving at room temperature or drying, and the drying may be carried out through an oven or hot air drying. The drying may be carried out at a temperature of 30 ° C to 90 ° C, specifically 40 ° C to 70 ° C. If the drying temperature is lower than 30 ° C, the drying efficiency is lowered. If the drying temperature is higher than 90 ° C, the amount of water and solvent to be volatilized rapidly increases to cause flaking, which may affect molding stability. Also, the drying can proceed slowly for about 2 to 20 hours, and this moisture removal step (drying) can be carried out in a mold for molding the mixture into an appropriate shape.

Hereinafter, examples and experimental examples of the present invention will be illustrated. The following examples and experimental examples are provided to illustrate the present invention in order to facilitate understanding of the present invention, and thus the technical scope of the present invention is not limited thereto.
