Gelling agent for oil

Abstract

A compound represented by the following general formula (I), wherein R 1 and R 2 represent a hydrocarbon group having 1 to 26 carbon atoms, preferably a linear or branched alkyl group, R3 represents a hydrocarbon group having 7 to 10 carbon atoms, preferably a linear or branched alkyl group, n represents 1 or 2 provided that the acidic amino acid residue in the molecule is L-aspartic acid residue when n is 1 and said acidic amino acid residue is L-glutamic acid residue when n is 2, and a gelling agent for an oil comprising said compound.

What is claimed is:  
     
         1 . A compound represented by the following general formula (I):  
       
         
           
           
               
               
           
         
       
       Wherein R 1  and R 2  independently represent a hydrocarbon group having 1 to 26 carbon atoms, R 3  represents a hydrocarbon group having 7 to 10 carbon atoms, n represents 1 or 2 provided that the acidic amino acid residue in the molecule is L-aspartic acid residue when n is 1 and said acidic amino acid residue is L-glutamic acid residue when n is 2.  
     
     
         2 . The compound according to  claim 1 , wherein R 1  and R 2  independently represent a linear or branched alkyl group having 1 to 26 carbon atoms, R 3  represents a linear or branched alkyl group having 7 to 10 carbon atoms, and n represents 2.  
     
     
         3 . The compound according to  claim 1 , which is N-2-ethylhexanoyl-L-glutamic acid dibutylamide, N-octanoyl-L-glutamic acid dibutylamide, or N-decanoyl-L-glutamic acid dibutylamide.  
     
     
         4 . The compound according to  claim 1 , which is N-2-ethylhexanoyl-L-glutamic acid dibutylamide.  
     
     
         5 . A gelling agent for an oil which comprises at least one compound according to any one of  claims 1  to  4 .  
     
     
         6 . A gelling agent for an oil which comprises at least one compound according to any one of  claims 1  to  4  and N-lauroyl-L-glutamic acid dibutylamide.  
     
     
         7 . The gelling agent according to  claim 6 , wherein a ratio of total weight of the compound according to any one of  claims 1  to  4  and weight of N-lauroyl-L-glutamic acid dibutylamide is 35:5 to 5:35.  
     
     
         8 . A gel composition containing (a) a gelling agent according to any one of  claims 5  to  7 , and (b) at least one oil.  
     
     
         9 . The gel composition according to  claim 8 , which is a translucent composition.  
     
     
         10 . The gel composition according to  claim 8  or  9 , which further contains (c) at least one antiperspirant active ingredient.  
     
     
         11 . A cosmetic comprising a gel composition according to any one of  claims 8  to  10 .
