Description
Technical Field

Background
Pigments used in cosmetic preparations are required to have adhesion, concealing, spreadability, extensibility, hygroscopicity, oil absorption, skin affinity, and the like, and can be obtained by mixing or coating 2 or more pigments in various manners. In one example, when an inorganic pigment such as titanium dioxide has excellent adhesion, concealing force and the like, but the application feeling such as spreadability and extensibility is poor, in order to improve these disadvantages, although a technology for preparing a cosmetic having good concealing force, light refractive index difference and the like, that is, a technology for preparing an inorganic composite pigment by coating titanium dioxide with a certain proportion of silica has been disclosed in the prior art, there is a problem that the conventional coated inorganic composite pigment as described above has insufficient stability, adhesion, application feeling and durability with respect to skin and external conditions when actually applied to skin. In addition, the adhesion of cosmetic products is usually improved by increasing the content of extender pigment to increase the adhesion of friction and the like. However, there are problems inherent in the use of the cosmetic composition such as reduced spreadability and increased cosmetic thickness.
Accordingly, the present inventors have conducted various studies to improve the spreadability and the adhesion of a pigment, and as a result, have confirmed that a cosmetic composition containing a linear emulsifier as an active ingredient and a pigment having a surface coated with one or more substances selected from the group consisting of a silica gel/IPDI copolymer, a soybean amine and an alkyl titanium fatty acid salt exhibits excellent spreadability and adhesion, and have completed the present invention.

The results of experiments performed according to the methods described in 1-2-1 to 1-2-3 are shown in table 2 below, and the results of the sensory evaluation of the fitting force are graphically shown in fig. 1.
[ Table 2]
As shown in table 2 and fig. 1, the composition of example 1 of the present invention was confirmed to be extremely excellent in adhesion and spreadability, particularly in adhesion, unlike the composition of comparative example 1 containing an untreated pigment and the pigments of the compositions of comparative examples 2 to 4 containing a surface treatment with a surface treatment substance commonly used in the prior art.
Experimental example 2 determination of adhesive force and spreadability based on the type of emulsifier
2-1 preparation of the compositions of examples 1 to 4 and comparative examples 5 to 9
The compositions of examples 1 to 4 and comparative examples 5 to 9 were prepared according to the components (unit: wt%) shown in the following Table 3. Specifically, a pigment was added to the oil phase raw material, followed by stirring at room temperature for 10 minutes, after which the aqueous phase raw material was added and stirred at room temperature for 10 minutes to prepare a composition. The compositions of examples 1-4 were prepared by using a linear emulsifier, and the compositions of comparative examples 5-9 were prepared by using a branched emulsifier. In this case, the surface treatment substance of each pigment was used in a proportion of 7, with a total weight of 4% by weight of the pigment: 1:8 silica gel/IPDI copolymer, soya amine and alkyl titanium fatty acid salt to treat iron oxide pigment with a ratio of 1:1:5, silica gel/IPDI copolymer, soybean amine and alkyl titanium fatty acid salt. After the surface coating was completed, each surface-treated pigment was mixed with a pigment having a ratio of 80:15:3.5:1.5 surface-coated titanium dioxide, surface-coated yellow iron oxide, surface-coated red iron oxide, and surface-coated black iron oxide were mixed and used.
[ Table 3]
2-2 confirming the adhesion and spreadability of the compositions of examples 1 to 4 and comparative examples 5 to 9
Experiments were performed according to the methods described in 1-2-1 to 1-2-3, except that the compositions of examples 1-4 and comparative examples 5-9 were used instead of the compositions of example 1 and comparative examples 1-4. The results are shown in table 4 below, and in fig. 1, the results of the fit sensory evaluation are graphically shown.
[ Table 4]
As shown in table 4 and fig. 1, when the surface-treated pigment of the present invention is used in combination with an emulsifier having a linear structure, the adhesion force can be further improved without reducing the spreadability, as in examples 1 to 4. However, when the surface-treated pigment of the present invention is used in combination with an emulsified skeleton composed of an emulsifier of a branched structure of conventional comparative examples 5 to 9, the advantage of the surface-treated pigment is not highlighted. This shows that the surface-treated pigments of the invention have excellent adhesion and spreadability, i.e. have a synergistic effect, by combination with linear emulsifiers.

3-1 preparation of the compositions of examples 1 to 4, comparative examples 2, 10 to 12
The compositions of comparative examples 10 to 12 were prepared in accordance with the components (unit: wt%) shown in the following Table 5. Specifically, a pigment was added to the oil phase raw material, followed by stirring at room temperature for 10 minutes, after which the aqueous phase raw material was added and stirred at room temperature for 0 minutes to prepare a composition. The compositions of examples 1 to 4 and comparative example 2 were prepared according to the methods described in experimental examples 1-1 and 2-1. At this time, the treatment amount of the surface treatment substance of each pigment was 4% by weight based on the total weight of the pigment, and the use ratio was 7:1:8 silica gel/IPDI copolymer, soya amine and alkyl titanium fatty acid salt to treat iron oxide pigment with a ratio of 1:1:5, silica gel/IPDI copolymer, soybean amine and alkyl titanium fatty acid salt. After the surface coating was completed, each surface-treated pigment was mixed with a pigment having a ratio of 80:15:3.5:1.5 surface-coated titanium dioxide, surface-coated yellow iron oxide, surface-coated red iron oxide, and surface-coated black iron oxide were mixed and used.
[ Table 5]
3-2 confirming the adhesion and spreadability of the compositions of examples 1 to 4 and comparative examples 2, 10 to 12
Experiments were performed according to the methods described in 1-2-1 to 1-2-3, except that the compositions of examples 1 to 4, comparative examples 2, 10 to 12 were used instead of the compositions of example 1, comparative examples 1 to 4. The results are shown in table 6 below, and in fig. 1, the results of the fit sensory evaluation are graphically shown.
[ Table 6 ]
As shown in table 6 and fig. 1, when an emulsifier having a linear structure is used in combination with the surface-treated pigment of the present invention, the adhesion force can be further improved without reducing the spreadability, as in the compositions of examples 1 to 4. However, even if an emulsifier of a linear structure is used, the advantage of the emulsifier is not obvious if it is not used in combination with the surface-treated pigment of the present invention but is used in combination with a surface-treated pigment conventionally used in a large amount. This indicates that the linear structure of the emulsifier has excellent adhesion and spreadability, i.e., has a synergistic effect, by combining with the surface-treated pigment of the present invention.
Experimental example 4 confirming the adhesion and spreadability according to the content of the linear emulsifier
4-1 preparation of the compositions of examples 1, 5, 6 and comparative example 13
The compositions of examples 1, 5, 6 and comparative example 13 were prepared according to the components (unit: wt%) shown in the following table 7, specifically, pigments were added to oil phase raw materials, followed by 10 minutes at room temperature, after which aqueous phase raw materials were added and stirred at room temperature for 10 minutes to prepare compositions. The compositions of examples 1, 5, 6 and comparative example 13 were prepared by varying the content of the linear emulsifier in the composition. At this time, the surface treatment substance of each pigment was used in a ratio of 7, with a treatment amount of 4% by weight based on the total weight of the pigment: 1:8 silica gel/IPDI copolymer, soya amine and alkyl titanium fatty acid salt to treat iron oxide pigment with a ratio of 1:1:5, silica gel/IPDI copolymer, soybean amine and alkyl titanium fatty acid salt. After the surface coating was completed, each surface-treated pigment was mixed with a pigment having a ratio of 80:15:3.5:1.5 surface-coated titanium dioxide, surface-coated yellow iron oxide, surface-coated red iron oxide, and surface-coated black iron oxide were mixed and used.
[ Table 7 ]
4-2 confirming the adhesion and spreadability of the compositions of examples 1, 5, and 6 and comparative example 13
Experiments were performed according to the methods described in 1-2-1 to 1-2-3, except that the compositions of examples 1, 5, 6 and comparative example 13 were used instead of the compositions of example 1, comparative examples 1 to 4. The results are shown in Table 8 below.
[ Table 8 ]
As shown in table 8 above, it was confirmed by combining the results of the sensory evaluation of the adhesive force/spreadability and the results of the simple experiment of the adhesive force that the linear emulsifier had excellent adhesive force and spreadability when it was 1 to 5% by weight based on the total weight of the composition, and particularly when it was 3% by weight based on the total weight of the composition, the adhesive force and spreadability had the most coordinated feeling in use.
Experimental example 5 confirming the adhesion and the spreadability according to the content of the surface-treated pigment
5-1 preparation of the compositions of examples 1, 7, 8 and comparative examples 14, 15
The compositions of examples 1, 7, 8 and comparative examples 14, 15 were prepared according to the components (unit: wt%) shown in the following table 9, specifically, pigments were added to the oil phase raw materials, and then stirred at room temperature for 10 minutes, after which the aqueous phase raw materials were added and stirred at room temperature for 10 minutes to prepare the compositions. The compositions of examples 1, 7, 8 and comparative examples 14, 15 were prepared according to the different levels of the surface treated pigment in the compositions. In this case, the surface treatment substance of each pigment was used in a proportion of 7, with a total weight of 4% by weight of the pigment: 1:8 silica gel/IPDI copolymer, soya amine and alkyl titanium fatty acid salt to treat iron oxide pigment with a ratio of 1:1:5, silica gel/IPDI copolymer, soybean amine and alkyl titanium fatty acid salt. After the surface coating was completed, each surface-treated pigment was mixed with a pigment having a ratio of 80:15:3.5:1.5 surface-coated titanium dioxide, surface-coated yellow iron oxide, surface-coated red iron oxide, and surface-coated black iron oxide were mixed and used.
[ Table 9 ]
5-2 confirming the adhesion and spreadability of the compositions of examples 1, 7, and 8 and comparative examples 14 and 15
Experiments were performed according to the methods described in 1-2-1 to 1-2-3, except that the compositions of examples 1, 7, 8 and comparative examples 14, 15 were used instead of the compositions of example 1, comparative examples 1 to 4.
From the results of the combined adhesion/spreadability sensory evaluation, and the results of the adhesion easy experiments, it was confirmed that the surface-treated pigment had excellent adhesion and spreadability when it was 5 to 15% by weight based on the total weight of the composition, and especially when it was 10% by weight based on the total weight of the composition, the adhesion and spreadability had the most coordinated feel in use.
