EXAMPLES The paper-wrap pencil type cosmetics of the present invention will be described below with reference to Examples and Comparative Examples.

Example 1 On a paper (made by Anshingawa Paper Co., Ltd., pencil axis paper), a 15% solution of a water-soluble fluorine compound (Asahi Guard AG-made by Asahi Glass Co., Ltd.
530 ″) was applied at about 3 g / m _{2 and} dried at 120 ° C. for 5 minutes to prepare a fluorinated paper. This paper had a rectangular shape as shown in FIG. 1 and was slightly inclined with respect to its long side. In this state, a large number of perforation lines 1 such as perforations are provided in parallel at regular intervals, and circular holes 2 are formed between the respective perforation lines 1 along one short side of the perforation lines, and holes 2 are further provided. A paper 4 is formed by attaching a separating thread 3 in a position slightly inwardly parallel to the short side.Next, the paper 4 is attached to a cylindrical plastic rod 9 prepared separately therefrom. As shown in FIG. 3 (a), the end portion along the short side on the side provided with the hole 2 which is the outermost in the radial direction is adhered by wrapping around the short side on the side opposite to the side provided with the hole 2 as a center. Then, this wrapped paper 4
The surface of the paper was decorated by printing or the like, and then the plastic rod 9 inside the wound paper 4 was pulled out as shown in FIG. 3 (b) to form a hollow cylindrical shaft 5.

As shown in FIG. 3 (c), one end opening of the shaft 5 is sealed with a plastic stopper 7 and the other end opening is transferred to the inside of the shaft 5 with the following compounding ingredient: castor oil 40.8 (% by weight). Isopropyl barmitate 16.0 (wt%) Purified lanolin 7.5 (wt%) Lanolin alcohol 7.5 (wt%) Exposed beeswax 6.5 (wt%) Ozokerite 2.5 (wt%) Candelilla 7.5 ( Vitamin E 0.2 (wt%) Red No. 202 2.0 (wt%) Red No. 204 1.5 (wt%) Mica Titanium 8.0 (wt%) Lipstick that is solid at room temperature 8 was heated to 80 ° C. to inject and fill the melted fluid, and then the hot fluid of Lipstick 8 was cooled and solidified to complete a paper pencil type lipstick.

As shown in FIG. 2B, the paper-wrapped lipstick utilizes the separating thread 3 and the tear-off line 1 to gradually peel off the paper 4 from one end to easily expose the solid cosmetic (lipstick) 6. It can be used.

Example 2 A cylindrical shaft 5 similar to that of Example 1 was produced, and a foundation having the following composition was heated to be in a molten state, which was poured into the inside of the cylindrical shaft 5 to be filled and then cooled and solidified. This produced a paper pencil type foundation. Microcrystalline Wax 7.0 (wt%) Beeswax 3.0 (wt%) Glycerin monostearate 3.0 (wt%) Liquid paraffin 10.0 (wt%) Isopropyl myristate 15.0 (wt%) Mityl Poly Siloxane 20cs 16.3 (wt%) Titanium oxide 20.0 (wt%) Talc 20.5 (wt%) Red iron oxide 1.5 (wt%) Black iron oxide 0.5 (wt%) Yellow iron oxide 3.2 (weight%)

Comparative Example 1 The same procedure as in Example 2 was carried out except that a paper not treated with fluorine was used. Each of the paper winding foundations obtained in Comparative Example 1 and Example 2 was allowed to stand in a constant humidity chamber at 40 ° C. for 1 week to check whether the liquid oil contained in the paper winding foundation was spread on the paper of the jacket shaft. Then, it was inspected whether the properties of the paper winding foundation changed.
As a result, in Example 2, no bleeding of the liquid oil on the paper was found, and there was no change in the properties of the paper winding foundation, but in Comparative Example 1, bleeding of the liquid oil on the paper was found, and the paper winding foundation was also found. Since the liquid oil was absorbed into the paper, it became a sponge and became extremely fragile.
