Claims15
A non-aqueous liquid lubricant composition exhibiting lamellar liquid crystalline properties, said composition consisting of:
- (a) an organic acid component selected from the group consisting of alkyl phosphoric acids, aryl phosphoric acids, alkyl sulfonic acids, aryl sulfonic acids, and salts thereof;
- and
- (b) an organic amine component;
- wherein the non-aqueous lubricant composition does not contain a non-aqueous organic solvent and wherein the weight ratio of components (a) and (b) is in the range of about 1:1 to about 5:1;
- said composition further consisting of at least one additive selected from the group consisting of oxidation inhibitors, corrosion inhibitors and extreme pressure agents.

A lubricating composition comprising:
- a friction modifier formed of a non-aqueous lamellar liquid crystalline material comprising
- (a) an organic acid component selected from the group consisting of alkyl phosphoric acids, aryl phosphoric acids, alkyl sulfonic acids, aryl sulfonic acids, and salts thereof;
- and
- (b) an organic amine component;
- wherein said lamellar liquid crystalline material does not contain a non-aqueous organic solvent and wherein the weight ratio of components (a) and (b) is in the range of about 1:1 to about 5:1;
- said composition further including at least one additive selected from the group consisting of oxidation inhibitors, corrosion inhibitors and extreme pressure agents.

A non-aqueous liquid lubricant composition exhibiting lamellar liquid crystalline properties, said composition consisting essentially of:
- (a) an organic acid component selected from the group consisting of alkyl phosphoric acids, aryl phosphoric acids, alkyl sulfonic acids, aryl sulfonic acids, and salts thereof;
- and
- (b) an organic amine component;
- wherein the non-aqueous liquid lubricant composition does not contain a non-aqueous solvent and wherein the weight ratio of components (a) and (b) is in the range of about 1:1 to about 5:1;
