Abstract
The present invention addresses a problem of providing a grease composition that uses hydrophilic nanofibers but still has excellent water resistance and does not readily experience oil separation. The grease composition contains a base oil, hydrophilic nanofibers having a thickness (d) of 1 to 500 nm, and an organic bentonite.
Claims5
A grease composition comprising a base oil, from 0.1 to 20% by mass of hydrophilic nanofibers having a thickness (d) of 1 to 500 nm, based on the total amount of the grease composition, and from 1.0 to 10% by mass of an organic bentonite, based on the total amount of the grease composition, wherein the content ratio of the hydrophilic nanofibers to the organic bentonite is 1.0 to 5.0 as a ratio by mass,
- wherein the hydrophilic nanofibers contain one or more polysaccharides selected from cellulose, carboxymethyl cellulose, chitin and chitosan.
