Embodiment Construction

[0031] polyfoam

[0032] Accordingly, the present invention relates to a multifoam comprising at least one hydrophilic phase, at least one hydrophobic phase and at least one surfactant. More preferably, the polyfoam of the present invention comprises:

[0033] - at least one hydrophilic phase;

[0034] - at least one hydrophobic phase;

[0035] - at least one surfactant selected from ionic and / or nonionic surfactants;

[0036] - optional at least one additive selected from antioxidants, penetrants, viscosity modifiers, pH modifiers, buffers, preservatives, solubilizers, chelating agents;

[0037] - optional at least one active ingredient.

[0038] hydrophilic phase

[0039] According to one embodiment, the polyfoam of the present invention is a polyfoam wherein the hydrophilic phase is an aqueous composition or water.

[0040] The aqueous composition may comprise a water-miscible surfactant or polymer, and water.

[0041] hydrophobic phase

[0042]According to one em...

Abstract

The present invention provides a composition for use for topical application to the upper and / or lower eyelids of a subject, the composition comprising a polyfoam.

Description

technical field [0001] The present invention relates to easy-to-apply polyaphrons in the general field of galenic formulations. In particular, the present invention relates to compositions containing at least one polyfoam for topical application, preferably for eyelid application. Background technique [0002] Introduction of Polyfoam [0003] Polyfoams are dispersions. In the meaning of the present invention, "dispersion" means a system in which liquid beads or solid particles are dispersed in a continuous phase. In the present invention, the term "multifoam" refers to droplets of liquid called "foam" dispersed in a continuous phase in which the foam is immiscible. The dispersed phase may be a hydrophilic or hydrophobic phase, provided that the foam remains immiscible in the continuous phase. The continuous phase can be fluid, liquid or gel. [0004] More precisely, the dispersed phase of the multifoam may consist of a syntactic foam dispersed in a continuous phase, t...
