Abstract

A compound that thickens or gels a fluid organic substance to a desired viscosity or homogeneously stabilizes a composition containing a fluid organic substance, a thickening/stabilizing agent containing the compound, a thickened/stabilized composition containing the thickening/stabilizing agent and a fluid organic substance, and a method for producing a thickened/stabilized composition. The compound is represented by the following formula (1):

In the formula, R 1 and R 2 are different from each other and represent an aliphatic hydrocarbon group having not less than 4 carbon atoms, and n represents an integer of 1 to 3. The thickening/stabilizing agent of the present invention contains the compound.

First claim

The invention claimed is:

1. A compound represented by the following formula (1):

wherein
R 1 represents straight chain or branched chain alkyl groups having 6 to 20 carbon atoms,
R 2 represents straight chain or branched chain alkyl groups, alkenyl groups, or alkynyl groups having not less than 6 carbon atoms,
R 1 and R 2 are different from each other, and
n represents an integer of 1 to 3.

2. A thickening/stabilizing agent comprising
one compound according to claim 1 or two or more different compounds according to claim 1 ; and
at least one additional component.

3. A thickened/stabilized composition comprising the thickening/stabilizing agent according to claim 2 and a fluid organic substance.

4. A method for producing a thickened/stabilized composition, wherein a thickened/stabilized composition is obtained through a step of
compatibilizing the thickening/stabilizing agent according to claim 2 and a fluid organic substance.

5. The thickening/stabilizing agent of claim 2 , wherein the total content of said compound or compounds is not less than 0.5% by weight in said thickening/stabilizing agent.

6. The thickening/stabilizing agent of claim 5 , wherein the total content of said compound or compounds is not less than 85% by weight in said thickening/stabilizing agent.

7. The compound of claim 1 , wherein R 1 is ethylhexyl, R 2 is oleyl, and n is 2, said compound being
1,2,4,5-cyclohexanetetracarboxylic acid di(2-ethylhexylamide) di(oleylamide).

8. The compound of claim 1 , wherein R 1 is ethylhexyl, R 2 is stearyl, and n is 2, said compound being
1,2,4,5-cyclohexanetetracarboxylic acid di(2-ethylhexylamide) di(stearylamide).

9. The thickening/stabilizing agent according to claim 2 , wherein said at least one additional component comprises a base, a hydroxy fatty acid, an acrylic polymer, an oligomer ester, or metal oxide particles.
