Leave-on non-solid skin conditioning compositions are disclosed. The composition comprises from about 0.01 to about 15% by weight of the composition of 12-hydroxystearic acid, from about 0.1 to about 30% by weight of the composition of a nonionic surfactant and from about 0.05% to about 10% of a thickening polymer. The ratio of total nonionic surfactant to 12-hydroxystearic acid is in the range from about 90:10 to about 25:75. The weight ratio of the polymer to the total nonionic surfactant is in the range of from about 5:95 to about 70:30. The composition has a viscosity in the range of from about 1Pas to about 500 Pas and is structurally reversible through temperature cycling between room temperature and 50°C.
