The present invention provides a cosmetic composition containing a partially crystalline polyolefin homopolymer or copolymer wax and a solvent system. Specifically, the partially crystalline polyolefin homopolymer or copolymer wax is characterized by a refractive index ranging from about 1.4 to about 1.6, a viscosity measured at 170° C. ranging from about 5,000 mPas to about 15,000 mPas, a weight average molecular weight ranging from about 22,000 to about 28,000, and a polydispersity index ranging from about 2 to about 2.5. The solvent system is characterized by a refractive index that is matched with the refractive index of the wax and includes one or more solvents that are compatible with the wax for forming a solid, substantially clear, stick-shaped cosmetic product. 1. A method of making a solid , substantially clear stick-shaped cosmetic product comprising the steps of: (i) a refractive index ranging from about 1.4 to about 1.6,', '(ii) a viscosity measured at 170° C. ranging from about 5,000 mPas to about 15,000 mPas,', '(iii) a weight average molecular weight ranging from about 22,000 to about 28,000; and', '(iv) a polydispersity index ranging from about 2 to about 2.5,, '(a) mixing a partially crystalline polyolefin homopolymer or copolymer wax having all of the following characteristics(b) with a solvent system having a refractive index that is matched with the refractive index of the wax (a), wherein the solvent system comprises one or more solvents selected from the group consisting of tridecyl trimellitate, triethylhexyl trimellitate, isododecane, isohexadecane, isoeicosane, polyisobutene, isodecyl neopentanoate, lauryl lactate, ethylhexyl palmitate, octyldodecyl behenate, isododecyl ethylhexanoate, polyglyceryl-2 diisostearate, synthetic jojoba oil, octyldodecyl myristate, isononyl isononanoate, isodecyl isononanoate, isotridecyl isononanoate, octyl stearate, dioctyl adipate, dioctyl adipate/octyl palmitate/octyl stearate, octyl stearate/octyl palmitate ...
