Avon Products, Inc.
Compositions and methods of their use for improving the condition and appearance of skin
Disclosed are compositions and methods preferably aimed at 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 active agent is S-methyl-L-cysteine and S-phenyl-L-cysteine. This agent ameliorates, reduces, or treats progressive degradation of the dermal-epidermal junction and/or degradation of the cell-cell cohesion in skin.

Bioactive compounds and methods of uses thereof
The present invention relates to depside and diterpenoid compounds and methods for the prevention or treatment of, for example, a proliferative disorder, e.g., cancer, or symptom thereof. Pharmaceutical, nutraceutical and cosmetic compositions comprising depside and/or diterpenoid compounds are also encompassed. In this patent, these compounds are obtained from Rabdosia rubescens, a Chinese medicinal herb.

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 which is preferably a C10-C18 acrylates crosspolymer, and a crystalline gel structurant comprising a surfactant and cosurfactant. The structurant will have an enthalpy in the range of approximately 2 to 15 Joule per gram. The composition has a normal force in the range of +5 to +50 grams, thereby achieving a silky sensory feel on skin. The glycerin:copolymer is present in a weight ratio ranging from about 350:1 to about 10:1. Advantageously, the composition has a SkiCon Value ranging from about 10 to about 80.

L’Oréal
Composition having a healthy appearance effect
Disclosed are compositions containing at least one encapsulated pigment and at least one skin coloring agent chosen from self-tanning agents, melanogenesis activators and their mixtures. These compositions give an immediate healthy appearance effect that lasts over time.

Color Cosmetics

L’Oréal S.A.
Cosmetic composition comprising a polymer blend
The use of a polymer containing a specific hetero atom in a composition comprising particles of a film-forming polymer dispersed in the medium of the composition makes it possible to improve the adhesion properties of the composition on keratin materials, especially on keratin fibers such as the eyelashes. The composition is easy to apply to the keratin materials and allows the composition to be deposited quickly in an amount that is sufficient to obtain a makeup effect with the expected cosmetic properties. In particular, a thick deposit of the makeup on the keratin materials is quickly obtained. Thus, the formulator can prepare a mascara that quickly thickens the eyelashes, achieving instantaneous loading of the eyelashes. The mascara also gives good lengthening to the made-up eyelashes.

L’ Oréal
Poss containing cosmetic compositions having improved wear and/or pliability and methods of making improved cosmetic compositions
Film-forming and cosmetic compositions containing a combination of certain polyhedral oligomeric silsesquioxanes (POSS) and non-POSS silicone resins are described. The combination provides improved wear and/or pliability properties over previous silicone resin-containing compositions. Typically, the advantageous combinations will be formulated in a cosmetic composition that contains at least one solvent, and, preferably, a colorant, such as a pigment. Among the suggested finished product applications are foundations, mascaras, lip coatings (lip stick, lip gloss, lip pencil and the like) and nail coatings and the like.

Hair Care

Merck Chimie SAS
Compositions for body hairs and/or head hair
Proposed are compositions that can be applied to body hairs or head hair in order to make them stand up, for example for shaving. In the case of mascara compositions, the composition has good eyelash-curling properties and provides a uniform application that gives the eyelashes a natural appearance. The compositions comprise an aqueous suspension of magnetic latex microspheres and of colloidal nanoparticles of magnetic pigment. Specifically, the invention relates to a mascara, a shaving composition (foam, gel, cream, etc.) or a hair composition (lotion, shampoo, etc.).

L’ Oréal
Long-lasting cosmetic composition for application to human hair, such as eyelashes and eyebrows
There is a need for a mascara composition enabling the user to color her eyelashes easily without thickening them. The present invention provides a mascara composition giving a natural makeup result that stays on well over time, for longer than a day, or even two days or more, and that can be used to color human hair, such as eyelashes and eyebrows.
