The imidazolidine ring in the title compound, C19H24N2O2, adopts a twist conformation and its mean plane (r.m.s. deviation = 0.19 A ) makes dihedral angles of 72.38 (9) and 71.64 (9) with the two pendant aromatic rings. The dihedral angle between the phenyl rings is 55.94 (8). The molecular structure shows the presence of two intramolecular O-H...N hydrogen bonds between the phenolic hydroxyl groups and N atoms with graph-set motif S(6). In the crystal, C-H...O hydrogen bonds lead to the formation of chains along the b-axis direction.
