The coating film forming agent (a) forms a coating film on the makeup surface when cosmetics are applied to the skin. is composed of

The specific mixing ratio of the coating film forming agent (a) is shown in Table 1 below.

ingredient Formulation Example 1 Combination Example 2 Formulation example 3 Formulation example 4 Combination Example 5 cashew nut oil 20.0 wt% 50.0 wt% 30.0 wt% 20.0 wt% 50.0 wt% Schisandra oil 30.0 wt% 20.0 wt% 50.0 wt% 30.0 wt% 20.0 wt% Goji berry oil 50.0 wt% 30.0 wt% 20.0 wt% 50.0 wt% 30.0 wt% Sum 100.0 wt% 100.0 wt% 100.0 wt% 100.0 wt% 100.0 wt%

The cashew nut oil is obtained from the fruit bark of the cashew tree (Anacardium occidentale), an evergreen tree of the tropical plant Sumacaceae. It is reported that there are native places in the West Indies, Central America, Peru, etc. After spreading to India, it is also cultivated in the tropics of Africa and Southeast Asia. The components are reported as anacardic acid (70 ~ 80%), cardanol (14 ~ 20%), and cardol (2 ~ 7%).

The Schisandra oil is crushed Schisandra seeds to a size of 0.1 to 0.3 mm, and then the Schisandra seeds and hexane (normal hexane) are mixed in a ratio of 1: 4 to 6 based on the weight ratio, and maintained at 55 to 60 ℃ for 10 ~ The one obtained by repeating extraction three times for 14 hours is used.

And the Goji berry oil is after crushing the Goji berry seeds to a size of 0.1 ~ 0.3 mm, and then mixing the Schisandra seeds and hexane (normal hexane) in a weight ratio of 1: 4 ~ 6, and maintaining 55 ~ 60 ℃ 10 The one obtained by repeating extraction three times for ~ 14 hours is used.

When the amount of the coating film forming agent (a) used is less than 20.0 wt%, the coating film is not formed properly on the makeup layer, so the improvement of durability and the anti-staining effect may be reduced. Since there is a risk of performance degradation due to an increase in manufacturing cost and an imbalance of the overall component balance of cosmetics, the amount of the coating film forming agent (a) is preferably limited within the range of 20.0 to 50.0 wt% based on the total weight of the cosmetic composition. .

The oil binder (b) is used in the cosmetic composition to increase the bonding force between the components to improve physical properties and stability, and to improve water resistance, oil resistance and adhesion properties.

More specifically, the oil binder (b) is composed of 40.0 to 60.0 wt% of silicone oil and 40.0 to 60.0 wt% of squalane oil.

More specifically, it is composed of 60.0 wt% of silicone oil and 40.0 wt% of squalane oil.

When the amount of the oil binder (b) added is less than 5.0 wt%, the effects of using the oil binder such as improving water resistance, oil resistance and adhesion are insignificant. Since the physical properties may be adversely affected, the amount of the oil binder (b) added is preferably limited to 5.0 to 15.0 wt% based on the total weight of the cosmetic composition.

The natural adhesive (c) is composed of 20.0 to 50.0 wt% of porous starch, 20.0 to 50.0 wt% of casein, and 20.0 to 50.0 wt% of chitosan.

The mixing ratio between the components of the natural adhesive (c) is shown in Table 2 below.

When the amount of the natural adhesive (c) added is less than 10.0 wt%, skin adhesion and sticking properties are deteriorated, and when it exceeds 30.0 wt%, the spreadability may be greatly deteriorated due to an excessive increase in viscosity, so the natural adhesive (c) The amount of added is preferably limited to 10.0 to 30.0 wt% with respect to the total weight of the cosmetic composition.

The titanium dioxide powder (d) is a thin film formed by coating the titanium dioxide surface of nanoparticles with a polymer, and is added to color cosmetics so that the color expression of cosmetics can appear more clearly.

When the addition amount of the titanium dioxide powder (d) is less than 2.0 wt%, the effect of improving color expression is insignificant, and when it exceeds 20.0 wt%, the dispersion stability of the composition may be deteriorated, so that the dioxide The amount of titanium dioxide powder (d) added is preferably limited to 2.0 to 20.0 wt% based on the total weight of the cosmetic composition.

In addition, the reason for the surface treatment of the titanium dioxide (Titanium dioxide) is to reduce the cohesive force between the particles to improve the dispersion stability. That is, the dispersion stability is excellent, so that the color expression of the pigment is well shown.

A specific example of the surface treatment of the titanium dioxide is as follows.

That is, toluene and acetoacetoxyethyl methacrylate (2-(acetoacetoxy)ethyl methacrylate; AAEMA) were added to the reactor and uniformly dispersed,

50 ~ 80 nm of titanium dioxide is added to the reactor, but 40.0 ~ 50.0 wt% of the titanium dioxide and acetoacetoxyethyl methacrylate (2-(acetoacetoxy)ethyl methacrylate; AAEMA) 50.0 After adding it so that it becomes a blending ratio of ~ 60.0 wt%,

The initiator AIBN (azobisisobutyronitrile) was injected into the reactor, stirred at 75 to 85 ° C. for 5 to 10 hours to react, and then centrifuged at 7,000 to 9,000 rpm to dry the separated precipitate at room temperature. Titanium dioxide powder can be obtained.

The natural skin stabilizer (e) is composed of 1.0 ~ 60.0 wt% of bamboo leaf extract powder, 1.0 ~ 60.0 wt% of water parsley extract powder, and 1.0 ~ 60.0 wt% of sea cucumber extract powder.

The bamboo leaf extract powder is obtained by mixing bamboo leaves and water in a weight ratio of 1: 15 to 30, extracting at 100 ° C. for 15 to 30 hours, and filtering the extract with filter paper under conditions of 0.1 to 0.3 mPA. The bamboo leaf extract obtained by concentration under reduced pressure in a vacuum rotation evaporator for 5 to 7 hours is freeze-dried and then pulverized.

The water parsley extract powder is obtained by mixing water parsley and 80% methanol in a weight ratio of 1: 10 to 20, followed by extraction at 70 to 80 ° C. for 2 to 4 hours, and the filtered filtrate of the extract at a condition of 0.1 to 0.3 mPA 5 ~ The extract obtained by concentrating under reduced pressure with a vacuum rotation evaporator for 7 hours was freeze-dried and then pulverized.

The sea cucumber extract powder is mixed with sea cucumber and ethanol in a weight ratio of 1: 10 to 12, and then extracted in a shaking incubator at 120 to 160 rpm for 65 to 75 hours at 24 to 26 ° C. The extracted extract is 7,500 in a centrifuge. The supernatant obtained by centrifugation at 8,500 rpm for 15 to 25 minutes was filtered with filter paper, and the filtrate was concentrated under reduced pressure at 0.1 to 0.3 mPA with a vacuum rotation evaporator for 5 to 7 hours. The obtained sea cucumber extract is freeze-dried and then pulverized.

Examples of blending between the ingredients constituting the natural skin stabilizer (e) are shown in Table 3 below.

When the amount of the natural skin stabilizer (e) added is less than 0.5 wt%, the antioxidant function is lowered, and when it exceeds 10.0 wt%, the amount of other ingredients is relatively reduced due to excessive use, so there is a risk of deterioration of overall functionality. Therefore, it is preferable to limit the addition amount of the natural skin stabilizer (e) within the range of 0.5 to 10.0 wt% based on the total weight of the cosmetic composition.

The maekmundongyeop extract is washed with water and dried with a freeze dryer, then processed into a powder form, and mixed with powdered maekmundongyeop and distilled water in a 1:10-12 weight ratio at 75-85° C. for 2-4 hours. Extraction under reflux, filtration of the extract with filter paper, and concentration of the filtered extract under reduced pressure for 5 to 7 hours at a condition of 0.1 to 0.3 mPA with a vacuum rotation evaporator is used.

The joiner extract is obtained by mixing joiner and ethanol in a weight ratio of 1: 5 to 10, leaching at room temperature for 24 hours, filtering the primary extract, and repeating the same method twice to mix the filtered extract at 58 to 63 ° C. Use the one obtained by concentrating under reduced pressure with a vacuum rotation evaporator for 5 to 7 hours.
