Abstract

This invention relates to cosmetic applications for topical applications to the human skin. In particular, it relates to anhydrous cosmetic and dermatological compositions, with the capacity for self-warming or self-heating upon application. The self-warming or self-heating cosmetic compositions of the present invention comprise: (i) from about 0.1 to about 99% by weight of an anhydrous skin care preparation; and (ii) from about 0.01 to about 99% by weight of a heating agent selected from polyvinyl amine, polyalkyleneamine or polyalkyleneimine.

Claims

exact text as granted — not AI-modified
1 . A topical self-warming or self-heating skin care composition comprising: 
 from about 0.01% to about 99% by weight of an anhydrous skin care material or composition, said anhydrous skin care material or composition comprises one or more of fat, oil linear volatile silicone, cyclic volatile silicone, linear non-volatile silicone, cyclic non-volatile silicone or wax; and    from about 0.01% to about 99% by weight of a heating agent selected from the group consisting of polyvinyl amine, polyalkyleneamine and polyakyleneimine, wherein said heating agent is activated upon contact with moisture from the skin.

       wherein R is C 2 -C 8  alkylene, C 3 -C 8  alkyl substituted alkylene, and mixtures thereof, the value of m is from 2 to about 700 and the value of n is from 0 to about 350, having a ratio of m:n that is at least 1:1 up to 10:1.  
     
     
         3 . The composition of  claim 1  wherein the heating agent is polyalkyleneamine.  
     
     
         4 . The composition of  claim 3  wherein the polyalkyleneamine is polyethyleneamine.  
     
     
         5 . The composition of  claim 1  wherein the heating agent is polyalkyleneimine.  
     
     
         6 . The composition of  claim 5  wherein the polyalkyleneimine is polyethyleneimine.  
     
     
         7 . The composition of  claim 6  wherein the polyethyleneimine is present in an amount of about 0.1% to about 50% by weight.  
     
     
         8 . The composition of  claim 6  wherein the polyethyleneimine is present in an amount of about 5.0% to about 30% by weight.  
     
     
         9 . The composition of  claim 1  wherein said anhydrous skin care material or composition comprises less than about 5% by weight of water.  
     
     
         10 . (canceled)  
     
     
         11 . The composition of  claim 1  wherein said oil is selected from a volatile oil, a non-volatile oil, synthetic glyceryl ester, semi-synthetic glyceryl ester, fatty acid mono-, di-, and triglycerides, glyceryl stearate, glyceryl dioleate, glyceryl distearate, glyceryl trioctanoate, glyceryl distearate, glyceryl linoleate, glyceryl myristate, glyceryl isostearate, polyethylene glycol (PEG) castor oils, PEG glyceryl oleates, PEG glyceryl stearates, PEG glyceryl tallowates, and mixtures thereof.  
     
     
         12 . The composition of  claim 1  wherein said wax is selected from the group consisting of animal wax, plant wax, mineral wax, and silicone wax.  
     
     
         13 . (canceled)  
     
     
         14 . A method for topically treating the skin comprising the steps of: 
 placing a composition on the skin, wherein said composition comprises:    from about 0.01% to about 99% by weight of an anhydrous skin care material or composition, said anhydrous skin care material or composition comprises one or more of fat, oil linear volatile silicone, cyclic volatile silicone, linear non-volatile silicone, cyclic non-volatile silicone or wax; and    from about 0.01% to about 99% by weight of a heating agent selected from the group consisting of polyvinyl amine, polyalkyleneamine and polyakyleneimine,    wherein upon contact of the skin with moisture the composition provides activation of said heating agent for providing self heating or self warming.
