Technical Abstract: Vegetable oil based grease is considered as a potential replacement for mineral oil based grease due to environmental reasons. These are mainly restricted to applications were the grease could come in direct contact with soil and water. This work mainly focuses on the development of soybean oil based grease using a variety of fatty acid component to make the thickener (metal soap). The physical and chemical properties of grease are discussed in terms of the fatty acid structure, metal to acid ratio, acid to base-oil ratio, etc. A transmission electron microscope (TEM) methodology was developed to study the nature and structure of soap dispersoid in grease matrix and their effects on the physical and chemical behavior.
