The present invention relates to novel anhydrous or water-in-oil synthetic ester compositions which are used in formulating dermatological products having uniform structure ranging in consistency from a soft gel to a hard stick. The compositions comprise a new component, dibehenyl fumaric acid ester, which has a melting point of approximately 72-74.degree. C. The dibehenyl fumaric acid ester component has exceptional benefits when used in combination with any cosmetically acceptable oil in varying ratios, to produce homogeneous materials having a uniform structure. The di-behenyl fumaric acid ester according to the present invention may be used to harden or stiffen any cosmetically acceptable oil or water-in-oil emulsions and can be used to create compositions varying widely in viscosity and/or hardness from gels to solid systems such as sticks or to enhance the stability of water-in-oil emulsions. The compositions according to the present invention are particularly useful as additives in dermatological products, including cosmetic compositions and can accommodate components which vary widely in hydrophobicity or hydrophilicity.
