Description

Raw material composition with excellent adhesion and darkening improvement effects and cosmetic composition containing the same The present invention relates to a raw material composition comprising bis-C16-18 alkylglyceryl undecyl dimethicone, polypropylsilsesquioxane, and trimethylsiloxysilicate, and a cosmetic composition comprising the same. Base makeup products serve to smooth the skin surface and enhance the adhesion and longevity of color cosmetics. Traditionally, silicone oils, waxes, emollients, various fillers, and film-forming agents have been used in base makeup products. These ingredients temporarily cover skin imperfections and contribute to improving the spreadability of foundations or concealers. However, it has been difficult to satisfy all diverse consumer demands, such as sebum control, pigment dispersion, and long-lasting wear, using only the above ingredients. Recently, silicone-based ingredients have been widely introduced into base makeup compositions, forming a thin, uniform film on the skin to provide a smooth feel and excellent adhesion. For example, bis-C16-18 alkylglycerylundecyl dimethicone has a structure possessing both hydrophilic and hydrophobic properties and is utilized as an emulsifying stabilizer and film-forming agent. This ingredient enhances the dispersibility of pigments, adds a natural glow to the skin, and prevents moisture loss. However, when used alone, there were limitations in achieving a balance of uniform pigment dispersion, long-lasting durability, and a fresh feel. As such, existing base makeup formulations utilized the advantages of individual silicone-based ingredients; however, relying solely on a single ingredient or simple combination made it difficult to simultaneously satisfy various requirements such as adhesion, longevity, and a fresh feel. In particular, it was difficult to achieve uniform dispersion of pigments, and while the skin appeared radiant immediately after application, a darkening phenomenon frequently occurred where the makeup gradually darkened over time and became duller than the natural skin tone. Furthermore, issues such as the formation of a thick film causing a stuffy feeling, residue remaining on the skin, or poor longevity were frequently pointed out. Moreover, irritation or skin troubles occurred depending on the skin type. Against this background, the inventors devised the present invention to provide a raw material composition that is differentiated from existing technologies in that it simultaneously achieves adhesion, durability, and a fresh feel, while enhancing pigment dispersibility to minimize darkening, by combining bis-C16-18 alkylglycerylundecyldimethicone, polypropylsilsesquioxane, and trimethylsiloxysilicate. This raw material composition can be included and used in cosmetic compositions. Bis-C16-18 alkylglycerylundecyl dimethicone, which possesses both hydrophilic and hydrophobic properties, can improve pigment dispersion, and polypropylsilsesquioxane and trimethylsiloxysilicate can each provide a matte finish and excellent water-repellent effect. Thus, it is possible to provide a raw material composition that adheres naturally to the skin while maintaining a clean makeup state for a long time without darkening, and a cosmetic composition containing the same. Figure 1 is the result of an adhesion test performed by applying a cosmetic composition containing a raw material composition according to one embodiment of the present invention to the skin. Figure 2 is the result of confirming the pigment dispersibility and darkening inhibition effect by applying a cosmetic composition containing a raw material composition according to one embodiment of the present invention to the skin.
