Abstract
Provided is a grease containing a base oil and a hydrophilic nanofiber, the hydrophilic nanofiber having a thickness (d) of 0.01 to 500 nm being dispersed therein. The grease is low in an environmental load and excellent in safety on the human body and also has an appropriate worked penetration and has a high dropping point, and therefore, it is also excellent in heat resistance.

A grease, comprising a base oil and a hydrophilic nanofiber, the hydrophilic nanofiber having a thickness (d) of 0.01 to 500 nm being dispersed therein.
A grease obtained by mixing a hydrophilic nanofiber having a thickness (d′) of 0.01 to 500 nm and a base oil.
A method for producing a grease, the method comprising:
- Step (1):
- mixing an aqueous dispersion in which a hydrophilic nanofiber having a thickness (d′) of 0.01 to 500 nm is blended in water, a base oil, and a dispersion solvent, to prepare a mixed solution.
