Thickener
An ingredient capable of converting base oil to semi-solid grease. The thickener can disperse itself within base oil in the form of fine particles to form stable a three dimensional structure, eventually changing the base oil to a semi-solid substance. Thickeners are basically materials classified into metal soap or non-soap types, which subsequently affect heat resistance, water resistance, shear stability and various other kinds of performance.
