Disclosed are non-aqueous compositions capable of forming a gel structure, comprising (a) a low molecular mass N-acyl glutamic acid diamide having a straight-chain alkyl group; (b) a low molecular mass N-acyl glutamic acid diamide having a branched-chain alkyl group; (c) at least one gel-promoting solvent which includes a substituted hydrocarbyl functional siloxane and/or a second, different gel-promoting solvent; (d) at least one active ingredient, and (e) optionally, at least one polyorganosiloxane-containing polymer; wherein the composition has a hardness value ranging from about 30 to about 300 gf, a melting point of about 50 0 C or higher. Methods of making and using the compositions are also disclosed. |
