L'Oréal S.A.
Cosmetic composition comprising a polymer blend
The invention relates to a composition comprising, in a physiologically acceptable medium, at least a first polymer containing hydrocarbon-based repeating units linked to a dispersion of particles of a second film-forming polymer that is insoluble in the medium. The hydrocarbon-based repeating units contain at least one hetero atom. The first polymer will have a weight-average molecular mass of less than 100,000. In addition to a polymer skeleton with the repeating units, the first polymer optionally may have at least one pendent fatty chain and/or at least one terminal fatty chain, which may be functionalized, containing from 6 to 120 carbon atoms. Applications are in makeup and caring for keratin materials.

Unilever Home & Personal Care USA, division of Conopco Inc.
Silky feel cosmetic emulsion chassis
Disclosed is a cosmetic composition that includes a high level of glycerin, a copolymer that is preferably a C10–C18 acrylates crosspolymer, and a crystalline gel structurant comprising a surfactant and cosurfactant. The structurant has an enthalpy in the range of approximately 2–15 J/g. The composition has a normal force of from about +5 to about +50 g, thereby achieving a silky sensory feel on skin. The glycerin and copolymer are present in a weight ratio ranging from approximately 350:1 to approximately 10:1. Advantageously, the composition has a SkiCon Value in the range of approximately 10–80.

Long-lasting cosmetic composition for application to human hair, such as eyelashes and eyebrows
The invention relates to mascara compositions. In one embodiment, it relates to a dye-free and wax-free mascara composition that lasts more than one day when applied to eyelashes, is resistant to water, and does not noticeably thicken eyelashes on application. In another embodiment, it relates to a wax-free mascara composition comprising solid particles of a film-forming acrylic polymer dispersed in a cosmetically acceptable aqueous medium. In other embodiments, the invention relates to makeup kits, articles, and methods for making up and/or coloring human hair, such as eyelashes and/or eyebrows, using these compositions.

Miscellaneous

L'Oréal, S.A.
Composition comprising at least one first semi-crystalline polymer and at least one second film-forming polymer
The invention relates to a composition comprising, in a physiologically acceptable medium, at least one first semi-crystalline polymer having a melting point of greater than or equal to 30°C and at least one second film-forming polymer capable of forming a hydrophobic film at room temperature. The composition makes it possible to obtain a film that is more resistant to removal by cold water than to removal by warm water. The composition can be applied to the making up and care of keratin materials.
