Description

FIELD OF THE INVENTION The present invention relates to a cosmetic composition having an oil phase in the form of particles and a cosmetic composition prepared thereby,

To a method for producing a cosmetic composition having a novel formulation and a cosmetic composition prepared thereby.

In the case of a cosmetic formulation having a transparent appearance, since there is no specificity of appearance, in order to introduce the merits of the cosmetic, there is only a method of appealing the feeling of use or effect of the cosmetic.

Accordingly, in case of transparent cosmetics, capsule, pearl, etc. were put in order to enhance the differentiation of the appearance, so that it was developed to attract the attention of the primary consumers. However, raw materials such as capsules and pearls, which are raw materials, have a disadvantage in that the production of copy products is also difficult.

Therefore, there is a need to develop a technique that can differentiate cosmetic formulations without the addition of a starter such as capsules, pearls, and the like.

The term "50% diameter of particle (D50)" means a particle size corresponding to 50% of the weight percentage in the particle size distribution curve, that is, a particle having a percentage of passing mass of 50%.

The method may not use an emulsifier to emulsify the water phase and the oil phase. Since the above method does not use an emulsifying method of emulsifying the water phase and the oil phase with an emulsifier, the prepared cosmetic composition can be kept transparent.

The method comprises mixing an aqueous component comprising an aqueous solvent and an aqueous thickener to prepare an aqueous phase.

In the step of preparing the aqueous phase, the aqueous components other than the aqueous thickener may be dissolved in an aqueous solvent and then mixed with an aqueous thickener. When the aqueous component other than the aqueous thickener is dissolved in the aqueous solvent, the temperature can be appropriately selected so that the aqueous component can be completely dissolved in the aqueous solvent. Specifically, the aqueous component excluding the aqueous thickener is heated at a temperature of 30 to 90 占 폚, 40 to 90 占 폚, 50 to 90 占 폚, 60 to 90 占 폚, 30 to 80 占 폚, 40 to 80 占 폚, 50 to 80 占 폚, , 50 to 90 占 폚, 60 to 80 占 폚, or 60 to 70 占 폚.

The aqueous component is not particularly limited as long as it is an aqueous component commonly used in cosmetics and has a property of being soluble in water. For example, the aqueous component may include purified water, alcohol, glycerin, butylene glycol, dipropylene glycol, and the like. The alcohol is not limited in its kind, but may be, for example, ethanol. The aqueous component may comprise one or more species.

The aqueous solvent may be purified water or alcohol, but is not limited thereto.

The cellulose may comprise a cellulose derivative.

The step of preparing the water phase may be carried out so that the aqueous components have a cohesive strength.

The method comprises mixing an oily component comprising an oil and an oily gelling agent to produce an oil phase.

The mixing temperature of the oil and the oily gelling agent may be 60 to 110 ° C, 70 to 110 ° C, 80 to 110 ° C, or 90 to 110 ° C, but is not limited thereto.

In one embodiment, the oil may include, but is not limited to, 1 to 20 wt%, 1 to 15 wt%, or 1 to 10 wt% based on the total weight of the composition.

The kind of the oil is not limited as long as it is oil commonly used in cosmetics. For example, the oil may be at least one selected from the group consisting of an ester-based oil, a hydrocarbon-based oil, a silicone-based oil, a vegetable oil, and triglyceride.

The ester-based oil may be an ester compound of a fatty acid and a fatty alcohol. For example, the ester-based oil may be selected from the group consisting of isopropyl myristate, isopropyl palmitate, Cetyl Octanoate, Cetyl 2-Ethyl Hexanoate, But are not limited to, 2-octyldodecyl myristate, di-isostearyl malate, and the like.

Examples of the hydrocarbon-based oil include petroleum-based oils such as liquid paraffin, vaseline, and isoparaffins; Synthetic oils such as hydrogenated polydecene, synthetic squalane, and polybutene; Vegetable oils such as vegetable squalane, hydrogenated squalane, and the like, but are not limited thereto.

The silicone-based oil may be an oil having a siloxane bond (Si-O-Si). For example, the silicone oil may be selected from the group consisting of Dimethicone, Dimethiconol, Phenyl Trimethicone, Disiloxane, Cyclomethicone, Cyclopentasiloxane, But are not limited to, cyclohexasiloxane and the like.

The vegetable oil may be an oil obtained from plants existing in nature. For example, the vegetable oil may be selected from the group consisting of olive oil, meadowfoam seed oil, rose hip oil, avocado oil, camellia oil, apple seed oil, grape seed oil, sunflower seed oil, macadamia seed oil, castor oil, jojoba seed oil, Ric / capric triglyceride, and the like, but are not limited thereto.

The triglyceride may be a compound in which three molecules of fatty acid are ester-bonded to glycerol.

The oily gelling agent may mean a material capable of making the oil phase into a gel state by crosslinking, coagulation or the like. For example, the oily gelling agent may be at least one selected from the group consisting of dextrin fatty acid ester, sodium stearate, and particulate silica, but is not limited thereto. The dextrin fatty acid ester may be an ester compound of dextrin derived from starch and a higher fatty acid. The dextrin fatty acid ester may include, but is not limited to, dextrin palmitate, dextrin laurate, dextrin myristate, dextrin stearate, dextrin palmitate / ethyl hexanoate, and the like. The oily phase obtained by using the oily gelling agent may be a transparent gel.

In one embodiment, the oily gelling agent may be included in an amount of 0.1 to 5.0% by weight, or 1.0 to 5.0% by weight based on the total weight of the composition, but is not limited thereto.

The oily components may be cohesive by performing the step of manufacturing the oil phase.

The method includes the steps of mixing and stirring the aqueous phase and the oil phase to prepare a cosmetic composition having a formulation in which the oil phase, which is a discontinuous phase, is distributed in the aqueous phase of the continuous phase.

The mixing and stirring may be performed while the oil phase is added to the water phase.

The agitation speed of the water phase and the oil phase may be 10 to 5000 rpm. When the stirring speed is less than 10 rpm, the oil phase is hardened into a single mass, and the oil phase can be separated into two phases without being distributed in the water phase. When the agitation speed exceeds 5000 rpm, the oily particles may be formed too small to confirm appearance differentiation, and may be oil-in-water emulsion formulations. An underwater type emulsion formulation can not form a transparent appearance because the appearance of the formulation is cloudy.

Mixing and stirring the water phase and the oil phase, and then cooling the water phase. In one embodiment, the aqueous phase and the oil phase may be mixed and stirred and then cooled to 45 ° C. In another embodiment, the water phase and the oil phase may be mixed and stirred and then cooled to 30 占 폚. In another embodiment, the water phase and the oil phase may be mixed and stirred and then cooled to 10 to 45 占 폚.

The method may further comprise, after the cooling step, a degassing step. The deaeration may mean removing the gas dissolved in the water phase and the oil phase. The degassing may be performed by a method commonly used in a cosmetic manufacturing process.

Since the cosmetic composition has viscosity in both the water phase and the oil phase, the oil phase may be distributed at a position immovable in the water phase.

The cosmetic composition may also contain additional ingredients commonly used in cosmetics such as preservatives, coloring matters, flavoring agents, fillers, preservatives, neutralizing agents, sunscreens, sweeteners, vitamins, free-radical scavengers, sequestering agents, ≪ / RTI > may further comprise any conventional cosmetic ingredients that may be selected from the < RTI ID = 0.0 >

One of ordinary skill in the art can select any additional components and / or amounts thereof so that the beneficial properties of the composition according to the present disclosure are not adversely affected or substantially not affected by the anticipated addition.

Another aspect provides a cosmetic composition having a formulation in which an oil phase is dispersed, which is a discontinuous phase in a continuous phase, prepared by a method for producing the cosmetic composition described above.

In one embodiment, the formulation may be that the oil phase, which is a discontinuous phase in the continuous phase water phase, is distributed in the form of particles having an average particle size of from 0.01 to 5 mm, from 0.1 to 5 mm, or from 1 to 5 mm.

The aqueous, oily, and cosmetic compositions are as described above.

The cosmetic composition may have a transparent formulation. In general, the cosmetic composition of a transparent formulation may not be able to add an oil component for maintaining a clear appearance. This is because when the formulation is made into an oil-in-water type emulsion formulation for adding an oil component, the formulation is not transparent and turbid. However, since the cosmetic composition produced by the method according to one embodiment is transparent to the oil phase which is a discontinuous phase in the aqueous phase of the continuous phase, transparency can be maintained and the moisture content of the cosmetic composition can be increased have.

Since the cosmetic composition has viscosity in both the water phase and the oil phase, the oil phase may be distributed at a position immovable in the water phase.

The cosmetic composition prepared in this way can be distinguished from the cosmetic composition in that the particles are distributed in the water phase even though capsules, beads and the like as raw materials are not used.

The term "about" or " approximately "means that the value referred to may vary to some extent. For example, the value may be 10%, 5%, 2% For example, "about 5" may be between 4.5 and 5.5, between 4.75 and 5.25, and more preferably between < RTI ID = 0.0 > , Or between 4.9 and 5.1, or between 4.95 and 5.05.

The expression "having," "having," "including," or "including" may refer to the presence of a feature (eg, a component such as a numerical value or a component) It does not exclude existence.

In this specification, singular forms also include plural forms unless the context clearly indicates otherwise. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In case of contradiction, this specification will control.

The method of manufacturing a cosmetic composition according to one aspect of the present invention can produce a cosmetic composition having a novel formulation in which a transparent oil phase is distributed in the form of particles in water phase without using an existing oil capsule or emulsifier.
