Abstract (en)
[origin: EP3677661A1] A grease composition containing a base oil (A), a urea-based thickener (B), an antioxidant (C), and a rust inhibitor (D), wherein in a particle size distribution curve obtained by measuring the particle size of particles containing the urea-based thickener (B) in the grease composition on a volume basis with light scattering, a peak indicating the maximum frequency satisfies the following Requirements (I) and (II):(I) a particle size indicating the maximum frequency of the peak is 1.0 µm or less; and(II) a half width of the peak is 1.0 µm or less.
