Description

Cosmetic composition for ultraviolet rays interception including positively charged oil

The present invention relates to a cosmetic composition for blocking UV rays, and more particularly, to a cosmetic composition for blocking UV rays containing positively charged oil, which can improve formulation stability by increasing the dispersibility of inorganic powder through positively charged oil. it's about

The water-in-oil (W/O) type sunscreen has improved water resistance compared to the oil-in-water (O/W) type sunscreen, and has the advantage of being able to use a high content of inorganic sunscreen that scatters ultraviolet rays rather than a UV absorber. Have. However, the water-in-oil type sunscreen has a problem that is accompanied by a sticky feeling due to the use of a surfactant having a low HLB (Hydrophilie-Lipophile Balance) value. In order to solve the problem of such a water-in-oil type sunscreen (stickiness phenomenon due to the use of a surfactant), a study in the art of using a water-in-oil type sunscreen as a powder emulsification (Pickering emulsion) formulation has been made. However, unlike the water-in-water type sunscreen that can stabilize large particles of several tens of μm with a three-dimensional thickener, etc., in the case of the water-in-oil type sunscreen, the use of raw materials that can improve stability is limited, so the above Couldn't solve the problem.

In the case of inorganic sunscreens coated with metal salts such as aluminum hydroxide and alumina and fatty acids such as stearic acid, they are well dispersed in highly polar ester oils such as alkyl benzoates, but ester oils have a residual feeling and stickiness. This makes it difficult to use in high doses. Therefore, in order to develop a light-feeling product, a volatile silicone oil or hydrocarbon-based oil can be used in the continuous phase, but in this case, the dispersibility of the inorganic sunscreen is low, so agglomeration between the powders (powders) Separation of oil that does not mix well with the phenomenon occurs. Therefore, in order to improve the dispersibility and formulation stability of the cosmetic composition for UV protection, it is necessary to find a component that serves as a crosslinking agent between an oil having a light feeling of use and an inorganic sunscreen.

In the present invention, when an inorganic sunscreen agent is dispersed only with silicone oil or a non-polar hydrocarbon-based oil, inorganic powder (powder) such as titanium dioxide is agglomerated due to low dispersibility and the oil is phase-separated. As one thing, by including positively charged oil in the cosmetic composition, the inorganic sunscreen agent is well dispersed in silicone oil or hydrocarbon-based oil, and through this, aggregation and phase separation of the inorganic powder are prevented, thereby improving formulation stability, In addition, it can be said that it is a unique invention that has not been found until now, which can realize a light and refreshing feeling of use. In other words, when the Pickering emulsion is formed with the inorganic powder having an amphiphilic property, the inorganic powder is uniformly arranged at the interface by the positively charged oil used in the present invention to improve formulation stability, By reducing stickiness and suppressing coalescence and separation caused by non-uniform particles, Pickering emulsions that are large at the level of several tens of micrometers are stabilized, making it possible to manufacture cosmetics that have a large inlay and are easily applied.

[Test Example 1] Formulation stability evaluation

The cosmetic compositions prepared in Examples 1 and 2 and Comparative Examples 1 and 2 were observed under an optical microscope (ECLIPSE 80i, Nikon, Japan) to evaluate formulation stability (powder emulsion stability). 1 is an image observed under an optical microscope of a cosmetic composition for UV protection prepared according to an embodiment and a comparative example of the present invention, wherein A in FIG. 1 corresponds to Example 1, and FIG. corresponds to, C in FIG. 1 corresponds to Comparative Example 1, and D in FIG. 1 corresponds to Comparative Example 2.

As a result of observation and evaluation of formulation stability of each cosmetic composition as described above, in Comparative Example 1 in which positively charged oil (aminopropyldimethicone or amodimethicone) was not used, as shown in FIG. 1 , titanium dioxide powder was While it was not uniformly arranged at the interface between the oil phase and the water phase, in the case of Example 1 or Example 2 using positively charged oil, titanium dioxide powder was uniformly arranged in the particles with a size of 10 to 20 μm at the interface between the oil phase and the water phase. could confirm that On the other hand, in the case of Comparative Example 2, the uniformity of the particle arrangement is externally similar to Example 2, but looking at the stability results in Table 2 below, Example 2 was at room temperature, 45 degrees, Cyc + Sh (Cycle + Shaking). ), it is stable under the cycle conditions, but in Comparative Example 2, it can be confirmed that the separation occurs quickly, indicating a clear difference in formulation stability.

[Test Example 2] Hardness and constant temperature stability evaluation

The hardness and constant temperature stability of the cosmetic compositions prepared in Examples 1 and 2 and Comparative Examples 1 and 2 were evaluated. Hardness was measured using SUN RHEO METER COMPAC-100 (SUN SCIENCTIFIC CO., LTD., Japan), and constant temperature stability was measured by putting each cosmetic composition in a thermostat maintained at a specific temperature, and the results are shown in Table 2 below. indicated. Meanwhile, in Table 2 below, Cyc + Sh (Cycle + Shaking) is measured in a constant cycle (heating from -15 ° C to 45 ° C, repeated for 12 hours at each temperature) in a constant temperature bath shaking at a rotation speed of 150 rpm. , Cyc (Cycle) is measured by heating from -15 ℃ → 45 ℃ and repeating for 12 hours at each temperature.

As shown in Table 2, in the case of Comparative Example 1 or Comparative Example 2 that did not use positively charged oil, the Pickering emulsified (powder emulsified) particles were large and not uniform, so coalescence between the particles occurred, and the hardness decreased after 4 weeks. , and also showed a problem in constant temperature stability as oil separation was observed under most temperature conditions. On the other hand, in the case of Examples 1 and 2 using positively charged oil, the Pickering emulsified (powder emulsified) particles were small and uniform, so that even after 4 weeks had elapsed, the hardness was maintained without drop, and stability at constant temperature was also excellent under all temperature conditions, Through this, it was confirmed that by using the positively charged oil, the oil separation phenomenon at room temperature and high temperature, which occurs when the inorganic powder was not sufficiently dispersed in the oil of the external oil phase, was improved. On the other hand, in the case of Comparative Example 1, along with the oil separation phenomenon, inorganic powders were not evenly arranged at the interface to form large particles, so particle coalescence occurred at cold and temperature, and the water in the inner phase was also separated. In Example 1 using , it was found that stability at cold temperature was improved without separation.
