ABSTRACT:
Non-aqueous lamellar liquid crystalline lubricant compositions comprise an organic acid component or a salt thereof, an organic amine component and a non-aqueous solvent which maintains the liquid crystalline properties of a mixture of the organic acid or salt thereof and the organic amine. The organic acid component is selected from the group consisting of alkyl phosphonic acids, aryl phosphonic acids, alkyl sulfonic acids and aryl sulfonic acids. The weight ratios of the components are such that the compositions exhibit lamellar liquid crystalline properties, the weight ratio of organic acid to organic amine is in the range of about 1:1 to about 5:1 and the solvent comprises not greater than about 75 weight percent of the composition.
