[0057] As is clear from the results in Tables 1-3, Examples 1-19 were cosmetics that exhibited excellent crack suppression at high temperatures, no color transfer, no film shrinkage, a matte texture, and suppression of wax precipitation at high temperatures. On the other hand, in Comparative Example 1, which did not contain component (a), the effect was insufficient as it did not suppress cracking at high temperatures, lacked film shrinkage, and did not produce a matte texture. In Comparative Example 2, which contained a large amount of component (a), the effect was insufficient as wax precipitated at high temperatures. In Comparative Examples 3 and 4, which contained beeswax or candelilla wax instead of component (a), the product felt sticky and burdensome during use, and cracking and wax precipitation were observed at high temperatures. In Comparative Example 5, which had a low amount of volatile hydrocarbons in component (b), sufficient effects were not obtained in preventing color transfer and wax precipitation. In Comparative Example 6, which did not contain the silicone-based coating agent component (c), the color transfer prevention effect was significantly reduced, and sufficient effects were not obtained. In Comparative Example 7, which contained hexa(hydroxystearic acid / stearic acid / rosinic acid)dipentaerythrityl instead of component (c), the product felt sticky during use, and sufficient effects were not obtained in preventing color transfer, achieving a matte texture, and suppressing wax precipitation at high temperatures. In Comparative Example 8, which did not contain ingredient (d), and Comparative Example 9, which contained magnesium aluminum silicate instead of ingredient (d), wax precipitation was observed at high temperatures, and sufficient effects were not obtained in terms of no color transfer, no film shrinkage, and matte texture.
