(2) powder other than component (f),

(3) composition consisting of a crosslinked organopolysiloxane and an oil which is liquid at room temperature,

(4) film-forming agent selected from the group of consisting of latexes, cellulose derivatives, silicone-modified polysaccharides, acrylic silicone base graft copolymers, trimethylsiloxysilicic acid, silicone-modified polynorbornene, fluorine-modified silicone resins, fluoro-resins, aromatic hydrocarbon resins, polymer emulsion resins, terpene resins, polybutene, polyisoprene, alkyd resins, polyvinyl pyrrolidone-modified polymers, rosin-modified resins, and polyurethane,

(5) surfactant other than component (a) and (e), and

(6) oil-soluble gelling agents, antiperspirants, UV absorbers, moisturizers, preservatives, bactericides, perfumes, salts, antioxidants, pH adjusting agents, chelating agents, refreshing agents, anti-inflammatory agents, brightening agent, cell activating agent, anti-skin-roughening agent, blood flow promotor, skin astringent, antiseborrheic agent, vitamins, amino acids, water-soluble polymers, and inclusion compounds.

2. The stick-shaped cosmetic composition of claim 1 , wherein an amount of the component (f) is 0.1 to 5% by weight.

3. The stick-shaped cosmetic composition of claim 1 , wherein the component (c) consists of water and at least one component selected from the group consisting of moisturizers, humectants and mixtures thereof.

5. The stick-shaped cosmetic composition of claim 1 , wherein the component (c) consists of water, butylene glycol, and glycerol.

6. The stick-shaped cosmetic composition of claim 1 , wherein the amount of component (c) is 60 to 90% by weight of the total weight of the composition.

7. The stick-shaped cosmetic composition of claim 1 , wherein the amount of component (d) is 0.2 to 2% by weight of the total weight of the composition.

8. A stick-shaped cosmetic composition consisting of:
