A water dispersion type water and oil repellent composition which undergoes little change in viscosity even if freezing/thawing cycles are repeated and which is excellent in storage stability. The dispersion is capable of imparting excellent water and oil resistance to paper. A water dispersion type water and oil repellant composition contains a compound which is mixable with water and has a flash point of from 50 to 150° C. A polyfluoroalkyl group-containing phosphate may be incorporated into the mixture.
