An occlusive gel composition comprising: (i) a layered double hydroxide having general structure [A(1-x)Alx(OH)2]<x+> B<y->x/y . ZH2O where A is zinc, magnesium or calcium ions, B is an interlayer anion, y is a charge on the anion, x is 0.1 to 0.5, z is 0 to 100 providing that at least 50 % of the interlayer anion is selected from a monocarboxylic acid, a monoalkyl sulphate, a monoalkyl ether sulphate, an alkyl benzene sulphonate and mixtures thereof; (ii) a vegetable oil that is liquid at room temperature; and (iii) a secondary thickener that is solid at room temperature. |
