Abstract

Provided is a compound which thickens or gels a fluid organic material to a desired viscosity, or which uniformly stabilizes the formulation of a composition containing the fluid organic material.
The compound according to the present invention is represented by Formula (1):

R 1 —(CONH—R 2 ) n   (1)

where R 1 represents an n-valent aromatic hydrocarbon group containing two or more benzene rings; R 2 represents an aliphatic hydrocarbon group containing 6 or more carbon atoms; and n represents an integer of 4 or more. The group R 1 is preferably a group corresponding to an aromatic hydrocarbon selected from the group consisting of benzophenone, biphenyl, and naphthalene, except for removing hydrogen atoms in a number of n from the aromatic hydrocarbon. A thickening/stabilizing agent according to the present invention includes the compound.

First claim

The invention claimed is:

1. A compound of Formula (1):
R 1 —(CONH—R 2 ) n   (1)

wherein R 1 group is an n-valent aromatic hydrocarbon group selected from the group consisting of benzophenone, biphenyl, and naphthalene, except for removing hydrogen atoms in a number of n from the aromatic hydrocarbon group; R 2 groups are independently an aliphatic hydrocarbon group comprising 6 or more carbon atoms; and n represents an integer of 4 or more.

2. A thickening/stabilizing agent comprising
the compound according to claim 1 .

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

4. A method for producing a thickened/stabilized composition, the method comprising the step of:
dissolving the thickening/stabilizing agent according to claim 2 and a fluid organic material in each other.

5. The compound of claim 1 , wherein at least one aliphatic hydrocarbon group R 2 is selected from the group consisting of straight- or branched-chain alkyl group containing 8 to 18 carbon atoms, straight- or branched-chain alkenyl group containing 12 to 18 carbons and straight- or branched-chain alkynyl group containing 12 to 18 carbon atoms.
