Abstract
This invention relates to topical compositions in the form of dispersion gels formed by dispersing into an aqueous gel phase a substantially homogenous organic solution containing at least one active ingredient and at least one organic polymer solubilized in an organic carrier. The organic carrier comprises at least one water-miscible organic solvent and at least one water-immiscible organic solvent. The polymer is selected to affect efficacy of the compositions. The compositions are essentially free of surface-active substances and have favorable galenic properties.

A topical composition in the form of a dispersion gel comprising:
- at least one aqueous gel phase formed by processing at least one gelling agent with water,
- at least one organic phase formed by dispersing into the aqueous gel phase a substantially homogenous solution comprising at least one active ingredient and at least one organic polymer solubilized in an organic carrier consisting essentially of at least one water-miscible organic solvent and at least one water-immiscible organic solvent,
- wherein the organic polymer is selected to affect efficacy of the composition and the composition is essentially free of surface-active substances.
A composition in the form of a dispersion gel for topical delivery of at least one active ingredient, comprising:
- at least one aqueous gel phase formed by processing at least one gelling agent with water,
- at least one organic phase formed by dispersing into the aqueous gel phase a substantially homogenous solution comprising said active ingredient and at least one organic polymer solubilized in an organic carrier consisting essentially of at least one water-miscible organic solvent and at least one water-immiscible organic solvent,
