Avon Products Inc.
Compositions and methods of their use for improving the condition and appearance of skin
The present invention relates to compositions and methods for treating, preventing and improving the condition and/or aesthetic appearance of skin. It particularly relates to treating, preventing, ameliorating, reducing and/or eliminating fine lines and/or wrinkles of skin. The compositions include active agents that increase expression levels of genes associated with the dermatological signs of aging. The compositions are topically applied to the skin or are delivered by directed means to a site needing treatment. Dosage is once daily in an amount effective in improving the condition and/or aesthetic appearance of skin.

Sun Care

L'Oréal
Photoprotective compositions comprising methyltrialkylsilanes containing a cinnamate, cinnamamide, benzalmalonamide or benzalmalonate function
Unique photoprotective compositions contain novel methyltrialkylsilanes bearing a cinnamate, cinnamamide, benzalmalonamide or benzalmalonate function, useful as sunscreens that are active in the field of UV radiation.

Color Cosmetics

7,351,418
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.

Hair Care

7,351,406
Merck Chimie SAS
Compositions for body hair and/or head hair
Compositions that can be applied to body hairs or head hair comprise an aqueous suspension of magnetic latex microspheres and of colloidal nanoparticles of magnetic pigment.

7,351,405
L'Oréal
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

7,358,303
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.
