Specifically, 90% to 99.5% by weight of the powder based on the total capacity of 1kg is put into the reactor, and then 1% to 30% by weight of the powder active solvent is mixed while mixing at 300 rpm to 700 rpm to activate the primary powder in the weak acidic region. A continuous phase is made (S10-1).

In addition, while stirring the first powder continuous phase surface-activated with cations at 200 rpm to 400 rpm, 0.5% to 10% by weight of natural resin is slowly added to form a second powdery continuous phase (S10-2) .

Thereafter, the powder continuous phase is heated for a predetermined time to obtain a composite powder in which the natural resin is combined with the powder surface (S20). At this time, the step of obtaining the composite powder (S20) is dried at a reaction temperature of 50 ° C. to 120 ° C. for 2 to 24 hours to make a composite powder in a bulk state in which natural resin is composited on the surface.

Then, a step (S30) of homogenizing the composite powder through pulverization and filtering is performed. At this time, in the homogenization step (S30), the bulk composite powder obtained through the previous steps is pulverized by a grinding capacity device of 3HP or more and filtered through a 20 to 100 mesh to finally obtain uniform particles of natural origin. Resin surface-treated composite powder can be obtained.

On the other hand, the powder to which the present invention is applied is talc, kaolin, mica, sericite, nylon-12, methyl methacrylate crosspolymer, polymethyl methacrylate, boron nitride, alumina, titanium dioxide, zinc oxide, iron oxide, It may be at least one selected from the group consisting of silica, pearl, organic dyes, lakes, organic pigments, and mixtures thereof.

In addition, the natural resins include resins usable for cosmetics and derivatives thereof, such as Canadian balsam resin, balsam tolu resin, balsamcopaiba resin, red pepper resin, ladanum resin, jalapa resin, protium heptaphyllum resin, and myrrh resin. . -Hydrogenated Rosinate, Glyceryl Hydrogenated Rosinate, Dimer Dilinoleyl Hydrogenated Rosinate, Pentaerythrityl Rosinate, Pentaerythrityl Hydrogenated Rosinate, Dipentaerythrityl Hexahydroxystearate /Hexastearate/hexaloginate, methylroginate, PEG-3 diloginate, PEG 2-diloginate, sodium loginate, diethylene glycol loginate, zinc loginate, TEA-loginate , Triethylene Glycolloginate, Triethylene Glycol Hydrogenated Rosinate, Glyceryl Dimyristate / Hydrogenated Rosinate, Glyceryl Divehenate / Hydrogenated Rosinate, Dipentaerythrityl Hexahydrate hydroxystearate/hexastearate/hexahydrogenated rosinate, glycolozinate, rosin, hydrogenated rosin, AMPD-rosin hydrolyzed collagen, rosin acrylate, rosin hydrolyzed collagen, It may be at least one selected from the group consisting of glycerin/MA/rosin acid copolymer, dimer rosin, and mixtures thereof.

Specifically, by coating each powder such as white pigment, colorant pigment, pearl pigment, and extender pigment with natural resin, the adhesion to the skin can be improved and ultimately the durability of makeup can be increased.

And through this, it is possible to overcome the disadvantages that the conventional powder is coated with fatty acid, ester-based, pure silicone-based oil, etc., so that adhesion is low and color difference occurs due to darkening and that it is not skin-friendly.

Hereinafter, the actual composition ratio and manufacturing process of the cosmetic composition prepared by applying the surface-treated composite powder of the natural resin will be described in more detail.

The cosmetic composition containing the composite powder surface-treated with natural resin according to an embodiment of the present invention may include 5% to 30% by weight of the powder.

The cosmetic composition prepared by applying the composite powder surface-treated with natural resin according to an embodiment of the present invention was prepared according to the composition shown in Table 1 below.

First, the pigment (A) phase of components 1 to 5 of Table 1 is put in a mixer, and pulverized and mixed at room temperature at 800 rpm to 1,000 rpm for 5 minutes to obtain a mixture. The obtained mixture and the oil phase (B) phase of components 6 to 11 of Table 1 were put into an emulsification tank capable of stirring, heated and stirred at 70 ° C to 80 ° C, and stirred with a homomixer at a speed of 1,500 rpm to 2,500 rpm for 5 minutes to 10 minutes to mix evenly.

At this time, the powder is sufficiently stirred using a disper before being incorporated into the emulsification tank. The phases of the water phase part (C) of components 12 to 16 are put into a water phase dissolving tank capable of temperature control and stirring, and are stirred to dissolve and mix uniformly while maintaining the temperature at 60 ° C to 70 ° C.

Then, the water phase part of the prepared aqueous phase dissolving tank is put into the oil phase part of the vacuum emulsification tank, stirred and mixed for 5 minutes to 10 minutes at a speed of 1,500 rpm to 3,600 rpm with a homo mixer, and then cooled to 30 ° C to 35 ° C. Thereafter, the mixture is mixed by stirring for 2 to 3 minutes at a speed of 1,500 rpm to 3,600 rpm with a homo mixer in a vacuum emulsification tank. After stirring, cooling to 30 ° C. and degassing were performed to finally prepare a foundation.

In one embodiment of the present invention, the powder may be 5% to 30% by weight, preferably 5% to 25% by weight, more preferably 5% to 15% by weight, based on the total weight of the composition. If the content of the powder is less than 5% by weight, the effect on the properties and adhesion of the toilet paper is insignificant, and if it exceeds 30% by weight, there is a problem in that the application property is lowered.

Thus, with Example 1 for the cosmetic composition prepared by applying the naturally derived resin-coated powder, a patch test was conducted on 10 people to confirm the presence or absence of irritation.

Patch test subjects were healthy aged 25 to 35 years old, and the samples were applied to the inside of the lower extremities, removed after 24 hours, and observed after 1 hour, 24 hours, and 48 hours after removing the patch.

Grade Mean Score non-irritating (1) 0.00 to 0.75 mild (2) 0.76 to 1.50 light stimulation (3) 1.51 to 2.50 medium stimulation (4) 2.51 to 4.00 strong stimulation (5) 4.01 ~

The degree of skin irritation and evaluation criteria were confirmed by classifying them into five categories: non-irritating/mild irritation/mild irritation/mild irritation/strong irritation according to the visual evaluation criteria of FIG. The final decision was made according to the reactivity (mean score) calculation formula. As shown in Table 4, the average skin reactivity was '0', and it was confirmed that there was no irritation to the skin when the natural resin-coated powder was applied.

In addition, color difference according to time change was measured with CM-700d equipment of Konica Minolta Co., Ltd. in order to confirm the makeup lasting properties (color change, darkening) for Example 1 and Comparative Examples 1, 2, and 3.

The color value was measured before application of the sample of the test subject, and the color value was measured immediately after application and 6 hours after application to confirm each color difference value. Afterwards, the ratio of color difference values immediately after application and after 6 hours was checked, and the degree of color change was compared as shown in Table 5 below.

It can be said that the color change is small as the color change ratio is low, and the color change of Example 1 was the least. In addition, when looking at the degree of color expression through the color difference before and after application, excellent values were exhibited except for Comparative Example 3.

It can be confirmed that the powder is applied evenly and thinly, and the color development is relatively excellent. This shows that when the natural resin-coated powder is applied, the dispersibility is excellent, the color is expressed evenly, and the makeup durability is excellent with little color change.

In addition, for Example 1 and Comparative Examples 1, 2, and 3, the frictional force when applied to the skin was measured with HEIDON's Portable Sense of Touch Meter Type 33 equipment. By repeating the application after weighing the same amount of sample on the table, the friction coefficient was measured as shown in Table 6 below with the horizontal force (adhesive force) and vertical force (normal drag force) applied during formulation application. When applied with the same force, the adhesion was affected by the friction coefficient, and it was confirmed that the adhesion of Example 1 was the best.

According to the method for producing composite powder surface-treated with natural resin according to the embodiments of the present invention described so far and the cosmetic composition containing the composite powder prepared thereby, skin irritation is applied by applying the powder surface-treated with natural resin. It is possible to provide a cosmetic composition with excellent makeup lasting power, and to maintain makeup durability for a long time by reducing changes in skin color (darkening) over time by using powder coated with natural resin, and to maintain skin adhesion and pigment dispersion. By improving the, it is possible to provide a cosmetic composition of excellent quality to the user.

Although the above has been described with reference to an embodiment of the present invention, those skilled in the art variously modify and change the present invention within the scope not departing from the spirit and scope of the present invention described in the claims described below. You will be able to. Therefore, if the modified implementation basically includes the elements of the claims of the present invention, all of them should be considered to be included in the technical scope of the present invention.
