         5 . The method according to  claim 1 , wherein the volatile linear alkanes(s) are chosen from n-nonane, n-undecane, n-dodecane, n-tridecane and n-tetradecane, and mixtures thereof. 
     
     
         6 . The method according to  claim 5 , wherein the volatile linear alkanes are an n-undecane/n-tridecane mixture. 
     
     
         7 . The method according to  claim 1 , wherein the volatile linear alkanes(s) represent from 0.5% to 90% by weight of the total weight of the composition. 
     
     
         8 . The method according to  claim 1 , wherein the nonionic associative polymer(s) are chosen from:
 (1) celluloses modified with groups comprising at least one fatty chain;   (2) hydroxypropyl guars modified with groups comprising at least one fatty chain;   (3) copolymers of C 1 -C 6  alkyl methacrylates or acrylates and of amphiphilic monomers comprising at least one fatty chain;   (4) copolymers of hydrophilic methacrylates or acrylates and of hydrophobic monomers comprising at least one fatty chain;   (5) polyurethane polyethers comprising in their chain both hydrophilic blocks usually of polyoxyethylenated nature and hydrophobic blocks which may be aliphatic sequences alone and/or cycloaliphatic and/or aromatic sequences;   (6) polymers with an aminoplast ether backbone containing at least one fatty chain; and   (7) copolymers of vinylpyrrolidone and of fatty-chain hydrophobic monomers.   
     
     
         9 . The method according to  claim 8 , wherein the wherein the nonionic associative polymer(s) are chosen from polyurethane polyethers that comprise at least two hydrocarbon-based lipophilic chains, containing from 8 to 30 carbon atoms, separated by a hydrophilic block, the hydrocarbon-based chains being pendent chains or chains at the end of a hydrophilic block. 
     
     
         10 . The method according to  claim 1 , wherein the nonionic associative polymer(s) represent from 0.05% to 10% by weight of the total weight of the composition. 
     
     
         11 . The method according to  claim 1 , wherein the composition further comprises one or more non-silicone fatty substances. 
     
     
         12 . The method according to  claim 1 , wherein the composition further comprises one or more silicones. 
     
     
         13 . A composition comprising, in a cosmetically acceptable medium, one or more volatile linear alkanes and one or more nonionic associative polymers, wherein the nonionic associative polymer(s) are chosen from:
 (1) celluloses modified with groups comprising at least one fatty chain;   (2) hydroxypropyl guars modified with groups comprising at least one fatty chain;   (3) copolymers of C 1 -C 6  alkyl methacrylates or acrylates and of amphiphilic monomers comprising at least one fatty chain;   (4) copolymers of hydrophilic methacrylates or acrylates and of hydrophobic monomers comprising at least one fatty chain;   (5) polyurethane polyethers comprising in their chain both hydrophilic blocks usually of polyoxyethylenated nature and hydrophobic blocks which may be aliphatic sequences alone and/or cycloaliphatic and/or aromatic sequences; and   (6) polymers with an aminoplast ether backbone containing at least one fatty chain.
