The invention relates to a composition for topical application in the form of an o/w emulsion containing at least one crosslinked 2-acrylamido-2-methylpropane-sulfonic acid polymer comprising at least one hydrophobic unit and at least one semi-crystalline polymer. The composition obtained reportedly has good stability and good cosmetic properties. The invention also relates to uses of the composition in cosmetics and dermatology, especially to care for, protect and/or make up facial or bodily skin and/or the lips, and/or for skin care, especially for treating dry and/or sensitive skin and for treating the signs of aging of the skin.

The applicant has discovered that the use of a combination of particular hydrophilic polymers and of particular lipophilic polymers makes it possible to obtain a stable o/w emulsion that has good cosmetic properties, even in the presence of fatty substances such as waxes, and that may be advantageously free of emulsifying surfactant conventionally used in o/w emulsions or contain only a very small amount thereof, and thus be well-tolerated by any skin type.

Solid oral film dosage forms and methods for making same

The current invention relates to improved pharmaceutical solid oral film dosage forms for the buccal and/or sublingual delivery of pharmaceutical, nutraceutical or cosmetic ingredients that are endowed with instant hydration potential and complete dissolution, potentially enabling the active ingredient to become immediately available for enhanced buccal and/or sublingual absorption and/or reduced absorption through the gastrointestinal route. The improved delivery systems for solubilizing and stabilizing pharmaceutically active ingredients exhibit enhanced stability by the use of a combination of crystallization inhibitors, which together can maintain the active ingredient in a desired plurality of particles in an effective size range within a polymeric film matrix.
