Patent ID: 8580283

Claim:
A method for imparting an unctuous film to the lips comprising applying thereto a composition comprising: (a) from 0.1 to 2.5% by weight of Bis-Stearyl Ethylenediamine/Neopentyl Glycol/Stearyl Hydrogenated Dimer Dilinoleate copolymer having an average molecular weight between 3,000 and 7,500 Daltons and being capable of forming a gel with low-polarity and nonpolar oils at or below a sol-gel transition temperature T gel wherein T gel is above body temperature; (b) from 5 to 12% by weight of a first wax component comprising linear polyethylene and microcrystalline petroleum wax having a melting point above T gel ; wherein said first wax component equals or exceeds, on a weight basis, the amount of said Bis-Stearyl Ethylenediamine/Neopentyl Glycol/Stearyl Hydrogenated Dimer Dilinoleate copolymer; (c) from 5 to 12% by weight of a second wax component comprising ozokerite and lanolin having a melting point at or below T gel ; and (d) from 40 to 80% by weight of one or more low-polarity or nonpolar ester oils capable of forming a gel with said Bis-Stearyl Ethylenediamine/Neopentyl Glycol/Stearyl Hydrogenated Dimer Dilinoleate copolymer at or below said sol-gel transition temperature T gel ; wherein the weight ratio of Bis-Stearyl Ethylenediamine/Neopentyl Glycol/Stearyl Hydrogenated Dimer Dilinoleate copolymer to said ester oils is less than 1:30; wherein said ester oils comprise an oil selected from triisostearoyl polyglyceryl-3 dimer dilinoleate, diisopropyl dimerate, triisostearyl trilinoleate, C 12-15 alcohols benzoate, octyldodecyl stearoyl stearate, diisostearyl fumarate, polyglyceryl-2 diisostearate/IPDI copolymer, and combinations thereof; wherein said composition is self-supporting at room temperature and is further characterized by a viscosity measured during a second shear cycle that is within ±20% of the viscosity measured during a first shear cycle at every shear rate between 1 and 10 sec −1 , wherein said first and said second shear cycles are identical and comprise increasing shear rates from 1 to 1,000 sec −1 .
