Example 1. The Preparation of Inventive Lipstick (Lip-Fondue) Cosmetic Composition (1)-(4)

[0066] When weighing in this experiment, the melting point of the composition must be 60 C. or higher, so that there is no loss due to weight loss (LOSS). The wax and gelling agents in the experiment must be weighed separately to afford an accurate blending. Each raw material listed in Table 2 (the amount was based on weight percent (%)) was weighed in a beaker, heated and dissolved at 80-95 C. in a molten bath (SUS vacuum tank, Packingman machine Co. Ltd, Hwasung city, Korea) to which a dispenser was attached, stirred at 1,000-2,000 RPM, and then the final mixture was prepared through a coloring and degassing process. The produced final mixture was introduced into a heating charger (lipstick automatic molding machine, Woojung Tech, Korea), heated and dissolved at 80-95 C. to directly perform primary charging to the final product container. The surface of the charged stick was melted with a heating charger at 300-400 C. as a post-heat, and then the stick was charged again and cooled naturally for 3-5 min at room temperature. After melting the cooled stick surface again with a post-heat of 300-400 C., the final product was prepared through a secondary cooling process at room temperature for 5-10 minutes (designated as inventive lip-fondue lipstick hereinafter).
