Abstract

The invention relates to novel biodegradable film-forming agents of biobased origin, obtained by esterification reaction between at least one polyalcohol and at least one polyacid, said polyacids and polyalcohols being selected so as to form solid crystalline or semicrystalline polyesters capable of forming a thin film, which can be used in the cosmetic field. In particular, one objective of the invention is to provide polyester compounds, from biobased compounds. Said biobased polyester compounds are not only capable of forming a thin film on the skin, but make it possible to ensure the adhesion of the formulation, and give it water resistance and oil resistance properties, a long wear property and transfer-resistant properties.

The invention relates to a composition for treating and/or preventing snoring, comprising at least one thermogelling polymer that includes water-soluble units as well as units having a lower critical demixing temperature in water. Said composition has the specific feature of being liquid in the packaging thereof and becoming a gel upon contacting mucus membranes at 37°C. Thermogelling makes it possible to precisely target the area to be treated while avoiding any running or migration of the material, and makes the sprayed composition difficult to wash off, thus increasing the duration of the presence thereof in the treatment area.
