Abstract: A pharmaceutical composition comprising a moulded body of a polymer matrix, said polymer matrix comprising at least one polyaphron dispersion and at least one pharmaceutically active agent dispersed therein.

Abstract: A solid composition comprising oil core aphrons dispersed in a solid surfactant.

Abstract: An aerosol composition which is prepared from a biliquid foam, an aqueous phase and a propellant, and wherein an oil soluble functional material is incorporated into the biliquid foam during preparation to enable this material to be more readily incorporated into the composition. The aerosol composition can be contained in a pressurized aerosol can and can be a polish, an air freshener, a repellant. a pre- or post-shave preparation, a shaving preparation or a follicle softener.

Abstract: A method for the preparation of a biliquid foam which does not rely upon the initial formation of a gas foam, in which a stirrer having a single or a multiplicity of blades is used, the stirrer being operated in a manner such that at least one part of the stirrer mechanism breaks the interface between the continuous polar phase used to form the biliquid foam and the air, the non-polar phase being added dropwise at least initially whilst stirring the continuous polar phase and the rate of addition of the non-polar phase being controlled so that a biliquid foam composition is formed.

Abstract: An aerosol composition which is prepared from a biliquid foam, an aqueous phase and a propellant.

Abstract: A method for coating the surface of a substrate and a surface coating made according to the method Involves contacting the surface with a dispersion of a film forming polymer containing droplets of a suspended biliquid foam or emulsion. Then the dispersion is allowed to dry so as to coat the surface with a coating comprising the droplets trapped within a film of the polymer.

Abstract: A stable dispersion comprising an oil-based biliquid foam and an aqueous gel which is suitable for use in the cosmetics, pharmaceuticals and other industries. The biliquid foam comprises a dispersion of oil droplets in an aqueous medium stabilized by only a small amount of surfactant, thus keeping the level of skin irritation low. The gel may be a colloidal aqueous gel.
