USPTO Abstract
A monohydric alcohol-free composition for topical use on human lips and skin. Said composition comprising a commercially acceptable carrier and solubilized ethylcellulose. The ethylcellulose being substantially solubilized in at least one solvent which may be a natural oil, triglyceride, propylene glycol ester, neopentyl glycol ester, fatty alcohol or mixtures thereof. The invention is advantageous in that the use of the above-described solvents in combination with ethylcellulose in a cosmetic or pharmaceutical composition enables effective amounts of ethylcellulose to more easily be solubilized into the cosmetic or pharmaceutical in the absence of alcoholic solvents, thereby forming improved formulations having enhanced durability and adhesion efficacies and that are more tolerable by the skin or lips, while advantageously avoiding the use of monohydric alcoholic solvents.
