(Polyoxyalkylenated Wax)
The composition according to the present invention comprises (a) at least one
polyoxyalkylenated wax. If two or more polyoxyalkylenated waxes are used, they may be the same or different.
The (a) polyoxyalkylenated wax has at least one polyoxyalkylene moiety. The
polyoxyalkylene moiety may be composed of oxyethylene, oxypropylene, oxybutylene, and mixtures thereof. Preferably, the polyoxyalkylene moiety may be a polyoxyethylene moiety.
The polyoxyalkylene moiety contains preferably from 2 to 160 oxyalkylene units, more preferably from 8 to 140 oxyalkylene units, even more preferably from 80 to 120 oxyalkylene units. It is preferable that the oxyalkylene units be oxyethylene units. The (a) polyoxyalkylenated wax can be prepared, for example, by the addition to wax of a plurality of alkyleneglycols, preferably ethyleneglycols. The term "wax" here means a lipophilic compound (in particular, a wax ester: an ester of a higher fatty acid (C10 or more, preferably C12 or more) and a higher alcohol (C8 or more)), which is solid at room
temperature (25°C), except for jojoba oil, with a reversible solid/liquid change of state, having a melting point of greater than or equal to 30°C, preferably 40°C, and more preferably 50°C, which may be up to 100°C.

It is even more preferable that the (a) polyoxyalkylenated wax be selected from jojoba wax PEG-80 esters and jojoba wax PEG-120 esters.
The (a) polyoxyalkylenated wax may function as a nonionic surfactant because it can have a polyoxyalkylenated moiety which is hydrophilic and a wax moiety which is hydrophobic. Thus, the (a) polyoxyalkylenated wax may have an HLB value. The HLB value may be from 10 to 20, preferably from 13 to 19, and more preferably 15 to 18.
The amount of the (a) polyoxyalkylenated wax(es) in the composition according to the present invention may be 0.01% by weight or more, preferably 0.05% by weight or more, and more preferably 0.1% by weight or more, relative to the total weight of the composition.

The measuring protocol of the hardness is as follows:
The wax is melted at a temperature equal to the melting point of the wax + 10°C. The molten wax is poured into a container 25 mm in diameter and 20 mm deep.

The texturometer spindle is displaced at a speed of 0.1 mm/s, and then penetrates the wax to a penetration depth of 0.3 mm. When the spindle has penetrated the wax to a depth of 0.3 mm, the spindle is held still for 1 second (corresponding to the relaxation time) and is then withdrawn at a speed of 0.5 mm/s.
The hardness value is the maximum compression force measured divided by the area of the texturometer cylinder in contact with the wax.

The composition according to the present invention can exert lengthening effects for keratin fibers such as eyelashes. Furthermore, the composition according to the present invention can also provide keratin fibers with cosmetic effects, in particular makeup effects such as volumizing effects (e.g., the thickness of the keratin fibers can be increased) and curl maintaining effects (e.g., the curl of the keratin fibers can be kept). The cosmetic effects including the lengthening effects provided by the composition according to the present invention can last for a long period of time. The composition according to the present invention can be applied evenly to keratin fibers such as eyelashes. Accordingly, the cosmetic effects by the composition according to the present invention can be provided from the root to the tip of the keratin fibers. Thus, the keratin fibers can show uniform appearance from the root to the tip thereof. EXAMPLES
The present invention will be described in a more detailed manner by way of examples. However, these examples should not be construed as limiting the scope of the present invention. The examples below are presented as non-limiting illustrations in the field of the invention.
Examples 1 to 4 and Comparative Examples 1 and 2
[Preparations]
The following compositions according to Examples (Ex.) 1 to 4 and Comparative Examples (Comp. Ex.) 1 and 2, shown in Table 1 , were prepared as a mascara in the form of an O/W emulsion by mixing the components shown in Table 1. The numerical values for the amounts of the components shown in Table 1 are all based on "% by weight" as active raw materials unless otherwise indicated.

[Evaluations]
(Lengthening)
Each of the compositions according to Examples 1 to 4, and Comparative Examples 1 and 2 was applied onto the eyelashes of panelists, and the length of the applied eyelashes was evaluated by visual observation in accordance with a score of from 1 to 10. The average of the score was categorized in accordance with the following criteria.
Very Good: 7.0 or more
Good: From 5.0 to less than 7.0
Fair: From 3.0 to less than 5.0
Poor: Less than 3.0
The results are shown in Table 1. (Summary) The composition according to Example 1, which includes jojoba wax PEG- 120 esters and tromethamine shows very good lengthening effects for eyelashes.
The composition according to Example 2, which includes triethanolamine instead of tromethamine in Example 1 shows good lengthening effects for eyelashes.
The composition according to Example 3, which includes aminomethyl propanediol instead of tromethamine in Example 1 shows good lengthening effects for eyelashes.
The composition according to Example 4, which also includes fibers (nylon-6) in addition to the ingredients of Example 1 also shows very good lengthening effects for eyelashes.
Examples 1-4 can provide eyelashes with sufficient lengthening effects It can be understood from Examples 1-4 that various alkaline agents can work with jojoba wax PEG-120, and that the use of tromethamine, with or without fibers, can provide best lengthening effects. The composition according to Comparative Example 1 , which excludes jojoba wax PEG-120 (on the other hand, the amount of water was increased to compensate for the exclusion) in the composition according to Example 1, did not show good lengthening effects for eyelashes.
The composition according to Comparative Example 2, which excludes jojoba wax PEG-120 (on the other hand, the amount of steareth-20 which has an HLB value similar to that of jojoba wax PEG-120 esters was increased to compensate for the exclusion) in the composition according to Example 1, did not show good lengthening effects for eyelashes.
Comparative Examples 1 and 2 cannot provide eyelashes with sufficient lengthening effects. It can be understood from Comparative Examples 1 and 2 that the use of jojoba wax PEG-120 is necessary to provide eyelashes with sufficient lengthening effects.
