Description

Base-powder for make-up having Talc-free, outstanding dispersibility and molding stability}

The present invention relates to a cosmetic base powder, and more particularly to a cosmetic base powder excellent in dispersibility and molding stability and lacking talc.

With the development of the industry, the desire for the beauty of human beings is increasing and the cosmetics industry is gradually developed. In particular, the color make-up, which maximizes various aesthetics, is widely used to cover the defects of the skin and to pursue external beauty, where color is important. . Recently, the consumer's pursuit pattern also favors functional color cosmetics in which skincare concept is introduced, in addition to providing flaw cover and external splendor. In addition, since the powder component used to hide the flaws and blemishes of the skin in the color cosmetics forms a film on the skin after makeup, it contains water to give a moist feeling of makeup that can solve the powder tightness. The tendency to prefer the Aqua concept is becoming clear.

In relation to the development of such a functional color cosmetics, the recent development trends of the cosmetics industry can be seen that the active research into the formulation with added functionality. For example, the development trend of lipstick in the skin physiology [Fragrance, J, Apr, 1992], the development trend of UV-protective makeup [Fragrance, J, May, 1999], the recent trend of foundation research [Fragrance, J, May, 2000], most of them are active in the development of color cosmetics for the prevention of ultraviolet rays, and it can be seen that products containing water are commercially available in the form of lipsticks and emulsion pacts in solid and emulsion types.

However, it can be seen that there is a limit to the development of a moisture-containing formulation as a powdery color cosmetics, and for this reason, only a small amount of the components could be used in cosmetics based on the skin care concept. As such skincare ingredients, for example, water, glycerin, arbutin, lecithin, licorice, vitamin-C, tocopherol ingredients are generally well known. Among the above components, the water-soluble liquid components (water) entangle the powder formulation, which lowers the stability, and because the compatibility between powder and water is poor, it causes agglomeration when it is used. Had to be satisfied.

In cosmetics used externally on the skin, the whitening ingredients are formulated primarily by mixing them with water, the most potent polar solvent that can dissolve the ingredients well. This is to allow water to act as a carrier of the whitening component and to disperse the whitening component at the molecular level and to deliver the active ingredient by mixing with fine gaps or lipids of the skin.

Skin color correction and wrinkle coverage, which are the main functions of color cosmetics, are the main purpose of use and are facing limitations in functional formulations. Wrinkle and whitening functional formulations are mostly the only form recognized for basic cosmetics or emulsified products in which an aqueous phase is present.

On the other hand, the dispersion theory can be explained by the zeta potential, which is the potential difference of colloidal particles suspended in the liquid phase. The particles dispersed in the solution are electrically charged on the surface with a negative (-) or positive (+) charge, and the concentration of (+) ions increases around the colloidal particles with negative (-) charges. Is achieved. Outside the fixed layer, there is a diffuse layer, so that the concentration of (+) ions is reduced so that (-) and (+) ions are balanced with each other. The potential difference between the starting point of the diffusion layer and the point where the (-) and (+) ions are balanced is called the zeta potential. This zeta potential is used as a measure to evaluate the stability of the dispersed sol because it represents the intensity of repulsion between charged particles in the dispersion. The higher the zeta potential of (-) or (+), the greater the electrical repulsive force between the particles.

The value of the zeta potential can determine the measure of dispersion stability. However, since this is measured after diluting the concentration of the dispersed sol, the value may vary depending on the actual concentration and temperature. Therefore, it should be compared only as a measure of stability. It has different zeta potentials depending on the solvent, concentration, pH, functional group and surface characteristics of the particles. Such zeta potential can be used in industry, but if the zeta potential is large and well dispersed, the zeta potential is easy to be used in the paint, pharmaceutical, and cosmetic industries, and the zeta potential is small for the wastewater treatment process.

In addition, talc (TALC), which is a periodic agent for powder-based makeup, is widely used in all fields of paper, textiles, rubber, pharmaceuticals, and cosmetics because it is inexpensive and is produced in large quantities. The name talc was originally used to refer to ore, but now pulverized powder is also called. Talc has physical properties such as low hardness (Moss hardness 1), low whiteness and low electrical conductivity. In addition, it is odorless, chemically and thermally inert, and has an advantage in use such as having a high absorption capacity of an emulsion. Talc is used 30-30% in compacts for light cover and good spreadability [F. V. Wells, Cosmetics and the skin, eds, I.I. Lubowe, 216, REINHOLD BOOK Co., New York (1964).

Talc is a clay mineral with an ideal formula of Mg ₃ SiO ₄ (OH) ₂ . The crystal structure is composed of two silica layers, the structure of which a magnesium layer is sandwiched between the base unit, and the bonding strength is weak and brittle compared to other clay minerals. The smoothness of talc is due to this structure. Talc has a very smooth crystal structure and has a fat-like texture and excellent optical properties. There is a refractive index as an index indicating optical properties. Talc has a smaller refractive index than white pigments such as titanium oxide and zinc oxide and has a smaller difference between the refractive index with water / emulsion. Therefore, when talc is air, it has a white pigment hiding power. When wet, it gives a sense of transparency. For example, talc is formulated for the purpose of making the flaws of the skin inconspicuous or preventing the T zone from bleeding by sebum secretion.

In the measurement of reflected light, mica (MICA) has a specific specular reflection effect to make it gloss, but talc has no specific specular reflection and suppresses gloss and gives a soft texture to the skin. Talc is used as a basis for baby powder or powdered products with its unique texture. This texture is a very smooth texture that cannot be obtained from other inorganic materials. Compared with the dynamic friction coefficient of representative inorganic powders used in cosmetics, the value of talc is smaller and the larger particle size is considered to have a smaller coefficient of dynamic friction. In addition, talc or emulsion is added as an excipient to increase strength. Improving this with emulsion alone can be a lot of oily, sticky, or poor makeup lasting, which can be prevented by adding talc [K. Takeda, et. al., Functional Cosmetology, Substantiation of Cosmetic Efficacy: Recent Progress and Future Promise, 280, Yakuji Nippo, Tokyo (2003)]. Although talc is prescribed as an important constitution pigment in powder-based makeup, with the asbestos talc wave in 2009, talc is recognized as a dangerous substance for cosmetics even if it is not talc containing asbestos [MS Choi, et. al., Regulatory research on food , drug & cosmetic , 6 (1-2), 19 (2011)].

Since then, the talc wave has been quieted, but in 2012, a family of victims of ovarian cancer who had been using Johnson & Johnson Company's baby powder for 40 years continued to file punitive damages against the company. Since the woman is 62 years old, she set a $ 1 million punitive damages per year, and a total of $ 62 million was recognized. The victims suffered from ovarian cancer because "the Johnson & Johnson baby powder contains talc, which causes cancer." The debate over Johnson & Johnson baby powder and ovarian cancer is ongoing and has resulted in over 2000 litigations [CH Lee, Sogang Law Review , 6 (1), 163 (2017)].

As such, talc continues to create issues around the world. So, while some powder-based make-up products remove talc of smooth feeling and use ingredients such as MICA and KAOLIN, TITANIUM DIOXIDE, ZINC OXIDE, an inorganic UV blocker that shows rough feeling. It is limited to non-functional products that improve the feeling without prescribing). In addition, when a large amount of mica instead of talc, sufficient molding stability is often not obtained.

With the establishment of the PA ++++ grade at the KFDA in December 2016, high-efficiency products with a PA grade of 16 or higher are needed to cope with the recent trend. Inorganic sunscreens such as titanium dioxide and zinc oxide have recently been spotlighted as they are relatively safe for the skin, but when applied to the product, they have a high covering power, causing cloudiness due to the high refractive index of the raw material itself, and have a rough feeling when applied. It has many problems with [H. S. Lee, Comparative Studies on the Dispersion Properties of Titanium Dioxide by Various Combinations of Oil and Dispersant, Master's Thesis, Ajou National Univ., Seoul, Korea (2010)]. In addition, even in oxides, as the particles are fined, the surface is activated and tends to be coagulated and oxidized. J. Chimera, Markets & Prospects of Nano Materials, 223, CMC BOOKS, Tokyo (2008)].

The present inventors have been devising a method for overcoming the existing formulation in such a conventional powder base makeup, using a surface treatment powder using a zeta potential difference that is a formulation containing an aqueous phase and can easily transfer a functional substance to the skin. By using the zeta potential difference which surface-treats hydrophobic silica on the surface of plate pigment through electrostatic attraction, it develops powder stabilized by dissolving whitening functional component in water phase component, stably encapsulating in hydrophobic silica, and confirming its effect He applied for a base powder. The zeta potential surface treatment powder includes Niacinamide, Silica silylate, Mica, Lauroyl Lysine, Silica, Glycerin, Triethoxy caprylylsilane, Hydroxyacetophenone, 1,2-Hexanediol, Centella Asiatica Extract, Dipropylene Glycol, Butylene Glycol, Caprylyl Glycol, Ethylhexylglycerin and Water It is characterized by consisting of a hydrophilic functional material and an aqueous phase component.

< Example  1> Zinc Oxide Selection Experiment

A hand mixer (FM 909W, Hanil Electric Co., Korea) and a hydraulic press (Powder Press, Interpack Korea Co., Germany) were used to prepare powder fact samples. Specifically, after the experiment according to each prescription, after the combination of 53mm in diameter, 5.6mm in height Nisansara to the metal mold, weighing 12.5g, applying a pressure of 80Bar (Powder Press, Interpack Korea co., Germany).

In order to select zinc oxide having the best dispersibility and excellent usability, seven kinds were used according to the surface treatment and particle size. Zinc oxide without surface treatment (ZANO 10, Umicore Co., Belgium) with a size of 0.035 μm, zinc oxide with 0.3 μm (XZ 300F, Sakai Chemical Industry Co., Japan), zinc oxide (XZ with 0.5 μm) 500F, Sakai Chemical Industry Co., Japan), 1 μm zinc oxide (HZ-30MD, Hanil Chemical Co., Korea) was used.

In Table 1, the detailed composition of the zeta dislocation surface treatment powder (third cell on the left) is as follows. The composition ratio below represents the composition ratio when one left cell is 100, and the detailed composition of the zeta potential surface treatment powder is the same in the remaining tables other than Table 1 above. That is, the detailed composition of zeta potential surface treatment powder is MICA 23.10wt%, SILICA SILYLATE 6.00wt%, TRIEHTOXYCAPRYLYLSILANE 2.10wt%, TITANIUM DIOXIDE 27.75wt%, ALUMINUM HYDROXIDE 1.05wt%, LAUROYL LYSINE 5.00wt%, HYDROXYPROPYL 7. , CYCLODEXTRIN 2.40wt%, POLYDEXTROSE 1.20wt%, RESVERATROL 0.66wt%, HYDROXYACETOPHENONE 0.30wt%, 1,2-HEXANDIOL 0.26wt%, CENTELLAASIATICA EXTRACT 0.15wt%, BUTYLENE GLYCOL 0.38wt%, CAPRYLYLENE GLYCOL 0.15wt wt%, ETHYLHEXYLGLYCERIN 0.10wt%, SILICA 5.00wt%, GLYCERIN 5.00wt%, Water 10.50wt%. However, in the present invention, the detailed composition of the zeta potential surface treatment powder is not limited as described above, and the detailed composition of the zeta potential surface treatment powder may be variously changed.

As a result of the zinc oxide selection experiment as described above, the hardness and quality evaluation results according to the zinc oxide surface treatment and particle size are shown in Table 2, Figures 1 and 2. Hardness measurement was performed using a powder hardness tester (D89079-Ulm, Zwick Co., Germany) to measure the hardness of a total of five locations in the middle and outside of the sample. In hardness measurement, Point 1 measured the hardness of the center of the sample, Point 2 on the upper left, Point 3 on the upper right, Point 4 on the lower left, and Point 5 on the lower right. The quality evaluation was performed by assigning five items of feeling of use, adhesion, spreading, coating, and covering power to a score of '5: excellent, 4: good, 3: normal, 2: poor, 1: bad'.

As a result, the hardness did not differ significantly depending on the zinc oxide surface treatment and the particle size. However, the result of the quality evaluation showed the best feeling when using the zinc oxide treated with TRIETHOXYCAPRYLYLSILANE surface treatment of 0.035 μm, sample E. Zinc oxide without surface treatment showed poor usability and spreadability as the particle size increased.

In addition, the result of dispersibility and molding stability according to the zinc oxide surface treatment and particle size is shown in FIG. Dispersibility check It was checked by whether puffing occurred by rubbing with puff until the contents of the sample became 2/3. The force when rubbing the contents of the sample applied a force similar to that when doing makeup. Molding stability check was confirmed by cracking of the edges by dropping the sample at a height of 1 m. Two or more samples were used for the measurement, and there was no break at one time, and it was judged to be stable when only the edge or the side part was slightly broken at two or more times. A digital camera (Model SLT-A35, Sony Co., Japan) was used to compare the dispersibility and molding stability. As a result, the molding stability showed good results for all the samples, but the dispersibility was poor in the sample having a particle size of 0.1 μm or more and caking occurred. Samples A and E with a zinc oxide particle size of 0.035 μm did not cause caking, which means that the smaller the particles, the larger the number of individuals per mass, and the larger the specific surface area. It became.

As a result, when prescribing TRIETHOXYCAPRYLYLSILANE surface-treated zinc oxide with 0.035μm of sample E, which had the best feeling of use and dispersibility, it was found that a functional powder pact product with excellent dispersibility and molding stability and without talc can be developed. Could.

As a result of the oil binder selection experiment as described above, the hardness and quality evaluation results according to the types of oil binders are shown in Table 6 and FIGS.

The hardness of Sample B using DIISOSTEARYL MALATE, which had a higher viscosity than 5000 cps was 5 cps DIMETHICONE and 15 cps PHENYL TRIMETHICONE, and this high viscosity material was inferior in dispersibility and caused high hardness due to coagulation between inorganic powders. I think it was. In terms of feeling, the adhesion of Sample B using DIISOSTEARYL MALATE was excellent and the spreadability of Sample D using DIMETHICONE was the best.

The dispersibility and molding stability results of the oil binder are shown in FIG. 9. Sample B using DIISOSTEARYL MALATE had poor dispersibility and caking, and sample D using DIMETHICONE showed poor molding stability.

In order to secure proper payoff and molding stability, the oil binder was examined. In the previous experiments, SERICITE surface-treated with silicone oil surface-treated composite powders, DIMETHICONE and METHICONE, was selected as a sieving pigment. The blending of DIISOSTEARYL MALATE and ISOTRIDECYL ISONONANOATE, which is a good feeling of use and good feeling of oil, has good spreadability, and it was judged that the double layer between powder particles could alleviate the rough feeling caused by the prescription of a large amount of titanium dioxide and zinc oxide. .

As a result of the dry binder selection experiment as described above, the insufficient molding stability was adjusted in detail, and the type of dry binder was examined for proper payoff. Hardness and quality evaluation results according to the dry binder type are shown in Table 8, FIGS. 10 and 11, and the results of dispersibility and molding stability are shown in FIG. 12. Of the four dry binders, only sample C using ZINC STEARATE was inferior in dispersibility, and caking occurred. Since ZINC STEARATE has 14 fatty acids and a large particle size, it is thought that caking has occurred because the specific surface area decreases and the binder absorption ability decreases. MAGNESIUM MYRISTATE was finally selected to compensate for proper payoff, spreadability, and molding stability.

As a result of the spherical powder selection experiment as described above, the spherical powder was examined for proper payoff and improvement of spreadability. Hardness and quality evaluation results according to the spherical powder type are shown in Table 10, Figure 13, 14, the dispersion and molding stability results are shown in Figure 15. When four kinds of spherical powders were used, all of the dispersibility was good, and the molding stability was only good with Sample D using NYLON-12. The NYLON-12 applied to the present invention had a surface curvature and the specific surface area was relatively higher than that of other spherical powders. Therefore, NYLON-12 was selected as the final spherical powder.

As a result of the above experiment, by using the zeta potential difference that the hydrophobic silica is surface-treated through the electrostatic attraction on the surface of the plate pigment, the whitening functional component is dissolved in the aqueous phase, and the powder is stabilized by inclusion in the hydrophobic silica. It was applied to make-up products, and reviewed the components of inorganic sunscreen zinc oxide, sieving pigment, oil binder, dry binder, and spherical powder. Experimental results were developed to develop the whitening high-functional powder pact.

One) As an inorganic sunscreen in powder-based makeup products, zinc oxide without surface treatment showed poor usability and spreadability as the particle size increased. By prescribing TRIETHOXYCAPRYLYLSILANE surface-treated zinc oxide, 0.035μm, which had the best feeling of use and dispersibility, it was possible to develop a functional powder pact product with no molding talc and excellent molding stability and dispersibility.

2) In the functional powder-based makeup products containing zeta potential surface treatment powder and not talc, the dominant pigments of DIMETHICONE and METHICONE surface treatments had the best usability and molding stability.

3) In the functional powder base makeup product containing zeta potential surface treatment powder and without talc, oil binder is DIIMESTEARYL MALATE, which has good compatibility with DIMETHICONE and DIMETHICONE which is well compatible with DIMETHICONE and METHICONE surface treatment. In addition, blending ISOTRIDECYL ISONONANOATE together gives good spreadability, and it is thought that the double layer between powder particles can alleviate the rough feeling of using a large amount of titanium dioxide and zinc oxide.

4) MAGNESIUM MYRISTATE supplements the proper payoff, spreadability and molding stability as a dry binder in functional powder-based makeup products that contain zeta potential surface treatment powder and do not prescribe talc.

5) NYLON-12 as a spherical powder in the functional powder-based makeup product containing zeta potential surface treatment powder and without talc showed the best molding stability and improved payoff and spreadability.

As a result, we confirmed the factors affecting dispersibility and molding stability by adjusting the raw material of the functional powder base makeup product which contains zeta potential surface treatment powder and did not prescribe talc. It was possible to establish a proprietary formulation of powder fact formulations that eliminated talc and had excellent dispersibility and molding stability.

The present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. This is possible.
