The amount of sodium stearoyl glutamate used is preferably limited within a range of 0.1 to 20% by weight based on the total weight of the cosmetic composition.

In addition, the second composition according to the present invention may comprise Magnolia sieboldii extract.

Magnolia sieboldii belongs to the Magnoliaceae family. It is also called the zucchini tree. It lives in deep mountain shady valleys and tattered rocks. Inhabits mainly in cool tattered rocks area. It is a large leafy tree with large leaves. Its stem is divided into several pieces and grows at an angle of about 7m. Branches spread over and over and the whole becomes rounded.

In the present invention, the Magnolia sieboldii extract means an extract obtained by extracting from various organs (for example, leaves, flowers, fruits, stems, branches, roots) of Angelica keiskei, and preferably an extract .

The Magnolia sieboldii extract of the present invention can be obtained by a conventional method known in the art, that is, under the conditions of ordinary temperature and pressure, using a conventional solvent (for example, water, an anhydrous or a lower alcohol having 1 to 4 carbon atoms , Acetone, ethyl acetate, butyl acetate or 1,3-butylene glycol).

According to one embodiment, the method for preparing the Magnolia sieboldii extract of the present invention is as follows. First, the larvae were cleaned with purified water, dried and crushed into small pieces, and then added with 1 to 10 times the dry weight of water, anhydrous or lower alcohol having 1 to 4 carbon atoms, acetone, ethyl acetate, butyl acetate or 1,3-butylene glycol and the like are added. Thereafter, the mixture is heated at 40 to 100 ° C for 3 to 20 hours for extraction by cooling with a cooling condenser to prevent evaporation of the active ingredient, or the mixture is extracted at 4 to 40 ° C for 1 to 15 days and completely dried by a rotary evaporator . In this case, in the case of 1,3-butylene glycol, it is difficult to dry using a rotary evaporator, so it is extracted directly under the above conditions and adjusted to a 1% (w / v) loss on drying.

Meanwhile, the Magnolia sieboldii extract of the present invention includes not only the extract obtained by the above-mentioned extraction method, but also the extract by supercritical extraction or ultrasonic extraction by decompression by carbon dioxide and high temperature.

The Magnolia sieboldii extract may be contained in an amount of 0.1 to 10% by weight based on the total weight of the cosmetic composition. When the extract of Magnolia sieboldii is contained in an amount of less than 0.1% by weight, there is a problem in the production of pearl, and when it is contained in an amount exceeding 10% by weight, it may irritate the skin.

In addition, the cosmetic composition according to the present invention may suitably contain the components ordinarily included in the technical field as the second composition or the third composition, respectively. The first to third compositions are classified for ease of mixing and manufacturing, and may be prepared by mixing together the second composition and the third composition, or the first to third compositions. Preferably, each composition may be separately mixed to improve the convenience of production such as confirmation of pearl formation.

The cosmetic composition according to the present invention can be produced by the following method. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a process for producing a cosmetic composition according to the present invention. FIG.

(1) Production of first composition (S11)

The first composition is prepared by completely dissolving rape sterol, PEG-5 rape seed sterol, Ceteth-3, Ceteth-5 and cholesterol (and sodium stearyl glutamate) at a high temperature, for example, about 90-100 ° C .

(2) Production of second composition and third composition (S12)

The second composition and the third composition containing Magnolia sieboldii extract are completely dissolved at 60 to 70 캜, respectively, to prepare the second and third compositions.

(3) The primary emulsification step (S13)

The first to third compositions are added to a stirrer (HOMO MIXER), followed by stirring at 5,000 to 6,000 rpm for 3 to 8 minutes. If the stirring speed is less than 5,000 rpm, mixing may not be performed. If the stirring speed exceeds 6,000 rpm, bubbles and excess energy may be consumed. Therefore, the stirring speed is preferably in the range of 5,000 to 6,000 rpm It is preferable to limit it. When the agitation time is less than 3 minutes, there is a problem that sufficient agitation can not be performed. When the agitation time exceeds 8 minutes, there is a problem that moisture is evaporated. Therefore, the agitation time is limited within a range of 3 to 8 minutes desirable.

(4) High-pressure emulsification step (S14)

The emulsion produced through the primary emulsification is passed through a high-pressure emulsifier (Micro Fludizer) to form the nanoparticles. In general, when passing through a high-pressure emulsifier, the oil passes through a gap having a diameter of several tens of microns, so that the flow rate of the emulsion increases sharply and the dynamic hydraulic pressure increases simultaneously. At room temperature, however, the static pressure decreases below the boiling point of the water, causing the water to boil at room temperature. The resulting bubbles explode when the emulsion passes through the gap, causing large emulsion particles to crumble to a small size. The average particle size produced in this process decreases in proportion to the number of times the high-pressure emulsion passes, and is influenced by the type of polymer used, the type and amount of oil, and the like. The high-pressure emulsification step is subjected to a high-pressure emulsification step under a condition of 600 to 1,000 bar using a high-pressure emulsifier. If the process is performed more than two times, it may be difficult to maintain a luminous pearlescent appearance evenly distributed with very small particles.

(5) Cooling step (S15)

In this cooling step, the emulsion obtained through the high-pressure emulsification step is cooled to a temperature at which the viscosity is completely formed, for example, up to about 33 ° C, preferably up to 25 ° C, and stirred to confirm that there is no viscosity rheism .

(6) Aging step (S16)

This aging step is a step of aging the emulsion obtained through the cooling step at room temperature for 20 to 30 hours, and finally undergoes the aging process to self-crystallize the cholesterol according to the present invention, .

Hereinafter, the present invention will be described in more detail with reference to the following Production Examples. However, the following Production Examples are intended to further illustrate the present invention, and the scope of the present invention is not limited to the following Production Examples.
