     BEST MODES FOR CARRYING OUT THE INVENTION 
     (Oily Composition) 
     The oily composition of the present invention comprises the following components (A), (B) and (C). 
     [Regarding Component (A)] 
     The component (A) is an N-acylamino acid derivative represented by the following formula (1). 
     
       
         
         
             
             
         
       
     
     In the formula (1), R 1  and R 2  represent each independently a hydrocarbon group having 1 to 26 carbon atoms, R 3  represents a hydrocarbon group having 7 to 18 carbon atoms, and n is 1 or 2. 
     The hydrocarbon group represented by R 1  and R 2  may be any of linear, branched, cyclic, or a combination thereof. As the hydrocarbon group represented by R 1  and R 2 , a hydrocarbon group containing an unsaturated bond may be used, however, it is preferable to use an alkyl group. As the hydrocarbon group represented by R 1  and R 2 , hydrocarbon groups having 1 to 10 carbon atoms are preferable, linear or branched alkyl groups having 2 to 6 carbon atoms are more preferable, linear or branched alkyl groups having 3 to 5 carbon atoms are further preferable, and a n-butyl group is most preferable. 
     As the hydrocarbon group represented by R 3 , a hydrocarbon group containing an unsaturated bond may be used, however, it is preferable to use a saturated hydrocarbon group. From the standpoint of easiness of production, the hydrocarbon group represented by R 3  is preferably a hydrocarbon group having 7 to 15 carbon atoms, more preferably a linear or branched alkyl group having 7 to 12 carbon atoms. 
     n is preferably 2. Therefore, the component (A) is preferably an N-acylglutamic acid derivative. 
     As the component (A), specifically, N-octanoyl-L-glutamic acid dibutylamide, N-2-ethylhexanoyl-L-glutamic acid dibutylamide, N-decanoyl-L-glutamic acid dibutylamide, N-lauroyl-L-glutamic acid dibutylamide, N-myristoyl-L-glutamic acid dibutylamide, N-palmitoyl-L-glutamic acid dibutylamide, N-stearoyl-L-glutamic acid dibutylamide and the like, can be used, and of them, N-2-ethylhexanoyl-L-glutamic acid dibutylamide and N-lauroyl-L-glutamic acid dibutylamide are preferably used, and it is preferable particularly to use both the compounds simultaneously from the standpoint of getting sufficient transparency. 
     In the oily composition of the present invention, the content of the component (A) is usually 0.1 to 25 wt %, preferably 0.5 to 15 wt %, more preferably 1 to 10 wt %. When the content of the component (A) is less than 0.1 wt %, gel strength is insufficient in some cases, and when the content of the component (A) is over 25 wt %, sufficient transparency cannot be gotten in some cases. 
     [Regarding Component (B)] 
     The component (B) is a polyamide resin. More specifically, it is as described below. 
     [1] It is preferable to use an amide-terminal polyamide resin represented by the following formula (2). 
     
       
         
         
             
             
         
       
     
     Specifically, “HAIMALATE PAM” (trade name; manufactured by Kokyu Alcohol Kogyo Co., Ltd.) can be used, and this is a (dimer dilinoleic acid bisdioctadecylamide/ethylenediamine) copolymer, wherein each R 1  is mutually the same or different and is linear or branched alkyl groups having 8 to 22 carbon atoms, each R 2  is dimer acid residues or dibasic acid residues, and n is 2 to 4 in the formula (2). 
     Further, “SYLVACLEAR A200V” (trade name; manufactured by Arizona Chemical Company) or “SYLVACLEAR A2614V” (trade name; manufactured by Arizona Chemical Company) can be used, in which each R 1  is alkylamine group residues having 14 to 18 carbon atoms, each R 2  is dimer dilinoleic acid residues, and n is 2 to 4 in the formula (2). 
     [2] It is preferable to use an ester-terminal polyamide resin represented by the following formula (3). 
     
       
         
         
             
             
         
       
     
     Specifically, “UNICLEAR 100VG” (trade name; manufactured by Arizona Chemical Company) can be used, in which each R 1  is stearyl alcohol residues, each R 2  is dimer dilinoleic acid residues, and n is 3 or 4 in the formula (3). 
     [3] As other polyamide resins, for example, “VERSAMID 930” (trade name; manufactured by Cognis) can be used. 
     Particularly, as the component (B), amide-terminal polyamide resins are preferable, and it is more preferable to use polyamide resins represented by the formula (2) (for example, “HAIMALATE PAM” (trade name; manufactured by Kokyu Alcohol Kogyo Co., Ltd.)) from the standpoint of getting sufficient transparency. 
     In the oily composition of the present invention, the content of the component (B) is usually 0.1 to 40 wt %, preferably 1 to 30 wt %, more preferably 2.5 to 25 wt %. When the content of the component (B) is less than 0.1 wt %, a sufficient pack feeling cannot be obtained in some cases, and when the content of the component (B) is over 40 wt %, elongation is poor in some cases. 
     Regarding the compounding ratio of the component (A) to the component (B) in the oily composition of the present invention, the ratio of the component (B) is usually 0.004 to 400 parts by weight, preferably 0.067 to parts by weight, more preferably 0.4 to 4 parts by weight with respect to 1 part by weight of the component (A). In the case of excess over the above-described range, it is difficult to get sufficient transparency in some cases, and a use feeling tends to deteriorate when processed into a preparation.

The lower limit of the solidification point is usually 40° C. or higher, preferably 45° C. or higher, particularly preferably 50° C. or higher from the standpoint of use as a rod-shaped article. 
     [Regarding Hardness of Oily Composition]

     A rheometer (trade name “NRM-2002)”, manufactured by Fudou Kougyou Inc.) is used, a cylindrical adapter having a diameter of 1 mm (adapter No. 6) is allowed to go into through a halfway position between the axis center and the inner periphery of a tubular container at a rate of 20 mm/min, and the maximum hardness value during 30 seconds from the ingress means the hardness in the present invention (unit: g/0.5×0.5×3.14 mm 2 ). 
     (Rod-Shaped Preparation) 
     The rod-shaped preparation of the present invention is obtained by solidification of the above-described oily composition of the present invention into a rod-shape. 
     For fabrication of the rod-shaped preparation of the present invention, the oily composition is melted by heating, then, filled in a tubular container and cooled. 
     As the tubular container to be used for the rod-shaped preparation of the present invention, known tubular containers can be used without particular restriction, and feeding containers widely used for lip rouges, lip creams and the like are preferably used from the standpoint of convenience of users. 
       FIG. 1  is a sectional view showing a rod-shaped article containing the rod-shaped preparation of the present invention. This rod-shaped article  100  is equipped with a rod-shaped preparation  2  and a feeding container  3 . The feeding container  3  is equipped with a tubular container  40  for storing the rod-shaped preparation  2 , a feeding mechanism  50  for feeding the rod-shaped preparation  2  stored in the container  40  out of the container  40 , and a cap  60  for covering the container  40 . The cap  60  is removable from the container  40 . 
     The container  40  has a circular cross-section. The rod-shaped preparation  2  is slidably engaged in the container  40 . 
     The feeding mechanism  50  is equipped with a bucket  51  and a rotation axis  52 . The bucket  51  has a concave portion  511  in which the rod-shaped preparation  2  is filled. The rotation axis  52  has a dial  521  exposed to the bottom and a center axis  522  coming up vertically into the container  40  from the dial  521 . The center axis  522  has a lot of grooves  523  on its surface. The bucket  51  is threadably mounted on the grooves  523  of the center axis  522 , and when the center axis  522  rotates, the bucket  51  moves up and down along the center axis  522 . According to the feeding mechanism  50 , the center axis  522  rotates owing to rotation of the dial  521 , followed by movement of the bucket  51  with the rod-shaped preparation  2  up and down in the container  40 , thereby feeding the rod-shaped preparation  2 . 
     The rod-shaped article  100  is used while feeding the rod-shaped preparation  2  in the container  40  out of the container  40  by the feeding mechanism  50 . Here, “feeding” means “drawing out and in” of the rod-shaped preparation  2  from and into the container  40 . 
     The above-described rod-shaped article  100  is produced via the following steps (1) and (2) in this order: 
     (1) a step of preparing the oily composition of the present invention, and 
     (2) a molding step of melting the above-described oily composition by heating, filling the melted material into the container  40 , and solidifying this into a rod-shape by cooling. 
     The bucket  51  has ribs  512  spirally extending on the inner periphery. In the drawing, the ribs  512  are formed in four rows. The molded rod-shaped preparation  2  does not come away easily from the bucket  51  owing to the ribs  512 . Thus, the rod-shaped preparation  2  is fed from the container  40  stably. The ribs  512  are formed not on the whole inner periphery of the bucket  51  but formed only on the upper inner periphery. If the ribs  512  are formed on the whole inner periphery of the bucket  51 , the rod-shaped preparation  2  in the bucket  51  becomes fragile. In the rod-shaped article  100 , however, the ribs  512  are formed only on the upper inner periphery of the bucket  51 , thus, it is possible to suppress the rod-shaped preparation  2  in the bucket  51  from becoming fragile. The number of the rows of the ribs to be formed is not particularly restricted. 
     According to the above-described method of manufacturing the rod-shaped article  100 , the productivity of the rod-shaped article  100  can be improved since the rod-shaped preparation  2  is formed directly in the container  40 . 
     The tubular container, the feeding mechanism (bucket and rotation axis) and the cap used in the rod-shaped article of the present invention are generally constituted of hard synthetic resins such as ABS, AS, polypropylene, polyethylene, polyethylene terephthalate, polyethylene naphthalate, polyester, polyvinyl chloride, polycarbonate and the like, and it is preferable to use hard synthetic resins having a heat resistance of 75° C. or higher. As such hard synthetic resins having a heat resistance of 75° C. or higher, specifically, ABS, AS, polypropylene and the like can be used. 
     Particularly, when the oily composition of the present invention has excellent transparency, it is preferable to use a tubular container made of a resin having high transparency. Regarding the transparency of the tubular container, the total light transmittance (JIS K 7361-1/2 mmt) is 70% or more, preferably 80% or more, more preferably 85% or more, particularly preferably 90% or more. Specifically, those made of an ABS resin having high transparency (for example, the total light transmittance (JIS K 7361/2 mmt) is 90% or more) are preferable as the tubular container. For the feeding mechanism, the bucket is preferably made of polypropylene, and the rotation axis is preferably made of polypropylene or an ABS resin having high transparency. The cap is preferably made of polypropylene.

     In Table 1, units of numerical values showing compounding ratios of components are parts by weight. 
     The oily compositions of Examples 1 to 4 and Comparative Examples 1 to 4 were melted by heating, then, filled in a tubular container and cooled, thereby obtaining rod-shaped preparations. Various physical properties, transparency and use feeling were measured by using these rod-shaped preparations. 
     [Regarding Physical Properties] 
     (1) Solidification Point 
     Five grams (5 g) of a rod-shaped preparation was crushed finely and charged in a 20 ml screw cap bottle. Then, a suitable amount of silicone oil was charged in a stainless bat, the bat was placed on a hot plate (trade name “ECHOTPLATE EC-1200N”, manufactured by ASONE Corporation) and heated, the screw cap bottle containing the above-described preparation was placed in the bat, and the above-described preparation was melted completely, then, allowed to stand at room temperature while keeping the condition unchanged. The temperature when solidification of the preparation was confirmed by a micro-spatula was adopted as the solidification point. As the thermometer, “CUSTOM CT-450WR” (trade name: manufactured by CUSTOM) was used. 
     (2) Melting Point 
     Five grams (5 g) of a rod-shaped preparation was crushed finely and charged in a 20 ml screw cap bottle. Then, a suitable amount of silicone oil was charged in a stainless bat, the bat was placed on a hot plate (trade name “ECHOTPLATE EC-1200N”, manufactured by ASONE Corporation) and heated, the screw cap bottle containing the above-described preparation was placed in the bat, and the appearance of the above-described preparation was observed visually and the temperature when the above-described preparation started to melt was adopted as the melting point. As the thermometer, “CUSTOM CT-450WR” (trade name: manufactured by CUSTOM) was used. 
     (3) Hardness 
     As the above-described tubular container to be filled with an oily composition, a cylindrical container having a diameter of about 13 mm and a height of about 60 mm was used. For cooling after filling, a constant temperature of 25° C. was kept for 12 hours or more. Ten millimeters (10 mm) of an upper part of the resultant rod-shaped preparation was cut, and the residual rod-shaped preparation was allowed to descend into the above-described tubular container. This was used as a sample for measurement. Its hardness was measured by using a rheometer (trade name “NRM-2002)”, manufactured by Fudou Kougyou Inc.). That is, a cylindrical adapter having a diameter of 1 mm (adapter No. 6) was allowed to go into through a halfway position between the axis center and the inner periphery of the above-described tubular container at a rate of 20 mm/min, and the maximum hardness value during 30 seconds from the ingress was adopted as the hardness (unit: g/0.5×0.5×3.14 mm 2 ). 
     [Regarding Transparency] 
     As the above-described tubular container to be filled with an oily composition, a cell having an optical path length of 10 mm (cell size: 10×10×45 mm, bilateral transmission type, made of polystyrene) was used. The cooling-solidified rod-shaped preparation was allowed to stand at 25° C. for 1 hour, and this was used as a sample for measurement. The transmittance of 600 nm through the above-described preparation in the above-described cell was measured by using a spectrophotometer (trade name “UV-2450”, manufactured by Shimadzu Corp.). In Table 1, 85 or more is represented by “⊚”, 75 or more and less than 85 is represented by “◯”, 50 or more and less than 75 is represented by “Δ”, and less than 50 is represented by “×”. 
     [Regarding Use Feeling] 
     (1) “Elongation” 
     On an area of 10 cm 2  (5 cm×2 cm) on the surface of an acrylic plate, 20 mg of the above-described preparation was applied. The dynamic friction coefficient with respect to the above-described preparation was measured by using a static and dynamic friction measuring machine Tribo-master (trade name “TL201S”, manufactured by Trinity Laboratory Co., Ltd.). That is, a friction sensitivity tester was moved at a rate of 2.0 mm/sec under a load of 100 g, and by this, the dynamic friction coefficient was measured. The measured data was transferred to a computer by using Condition catcher Model (trade name “MPL-10A-128”, manufactured by Kyushukyohan Co., Ltd.), and the average value of the dynamic friction coefficient was calculated in the computer. 
     The average value of the dynamic friction coefficient shows “sliding property” of the above-described preparation, and this “sliding property” and “elongation” have a correlation, thus, “elongation” can be evaluated based on the average value of the dynamic friction coefficient. Smaller the average value of the dynamic friction coefficient, better the “sliding property”. In Table 1, less than 1.00 is represented by “⊚”, 1.00 or more and less than 1.10 is represented by “◯”, 1.10 or more and less than 1.20 is represented by “Δ”, and 1.20 or more is represented by “×”. 
     (2) “Pack Feeling” 
     An evaluation was performed for Examples 1 to 4 and Comparative Example 1. The evaluation was performed by 10 monitors based on 5 step points. “Significant positive” is evaluated as 5 points, “positive” is evaluated as 4 points, “usual” is evaluated as 3 points, “negative” is evaluated as 2 points and “complete negative” is evaluated as 1 point, thus calculating the total point. The results are shown in Table 2.

     [Consideration] 
     (1) The preparations obtained by solidification of the oily compositions of Examples 1 to 4 have degrees of transparency of 85 or more and are excellent in transparency as compared with Comparative Examples 1 to 3 using oily gelling agents widely used in the art (12-hydroxystearic acid, dextrin palmitate, polyglycerin fatty acid ester) and Comparative Example 4 using only the component (A). The reason for this is believed as inclusion of a polyamide resin as the component (B). Therefore, the oily composition of the present invention is, when solidified and used as a preparation, capable of sufficiently exerting an advantage of transparency. 
     (2) The preparations obtained by solidification of the oily compositions of Examples 1 to 4 are excellent also in use feelings such as “elongation” and “pack feeling”. The reason for this is believed as inclusion of a polyamide resin as the component (B). Therefore, the oily composition of the present invention is, when solidified and used as a preparation, capable of providing a satisfactory use feeling. 
     (3) The preparations obtained by solidification of the oily compositions of Examples 1 and 2 are excellent particularly in “pack feeling”. The reason for this is believed as inclusion of a dimer acid ester as the component (C). 
     (4) Since the oily compositions of Examples 1 to 4 have low solidification points, solidification during a preparation step can be prevented, thus, handling thereof is easy. 
     Specific examples of the rod-shaped preparation of the present invention are shown in Table 3. As specific examples, two “lip rouges”, two “stick-form lip glosses” and three “transparent lip creams” are shown.
