PATENT PICKS
Polycyclic Compounds
7,307,078
Galderma Research & Development
Polycyclic compounds which modulate PPAR.gamma. type receptors and cosmetic/pharmaceutical compositions comprised thereof
This invention relates to a novel class of polycyclic compounds that are modulators of receptors of peroxisome proliferator-activated receptor type of subtype gamma (PPARγ). The invention also relates to a process for the preparation of these compounds and to their formulation into pharmaceutical compositions suited for human or veterinary medicine, or alternatively for cosmetic compositions.
High Foaming Hair Cleanser
7,307,050
Kao Corp.
Aqueous hair cleansing composition comprising a sulfate surfactant mixture and an amino-modified silicone
This invention relates to an aqueous hair cleansing composition that claims a good foaming property that produces abundant foam during shampooing, has a smooth foam quality, provides a smooth hair feel during rinsing, imparts hair with luster and manageability after drying, has good low-temperature stability, and that is substantially nonirritating. These properties are achieved by using polyoxyethylene added alkyl sulfates in which alkyl sulfates are distributed within a predetermined range on the smaller side of the number of moles of ethylene oxide addition, a specific amino-modified silicone derivative or a specific water-soluble cationic polymer, and a silicone oil having a small particle size in combination.
Fusion Protein for Transport
7,306,944
Polymer Ventures Inc.
Advanced cell-transducing transport domain-target protein-transport domain fusion protein and uses thereof
This invention provides a fusion protein that delivers a functional protein or peptide into a cell at enhanced efficiency. The fusion protein described is a transduction domain-target protein-transduction domain fusion protein, wherein the transduction domain is covalently bonded to each of the amino- and carboxyl-terminal ends of the target protein. Furthermore, the transduction domain comprises six to 12 amino acid residues, more than 75% of which are arginine or lysine residues. Green fluorescence protein and Cu/Zn-superoxide dismutase (SOD) are used as the target protein. Cosmetic compositions can be in the form of toilet water, gel, water-soluble liquid, o/w or w/o emulsions.
Optical Illusion Particles
7,306,809
Lipo Chemicals Inc.
Optically activated particles for use in cosmetic compositions
The optically activated particles of this invention include a solid substrate having a fluorescent compound fixed thereto, and coated or encapsulated with a transparent or translucent coating of cross-linked polyvinyl alcohol. These particles absorb light at a UV wavelength and emit visible light at longer wavelengths, and are able to both absorb and scatter light in a diffuse manner in order to reduce the visual perception of skin imperfections, including cellulite, wrinkles, shadows, skin discolorations, blotchiness and mild scars.
Hair Dyeing Process
7,303,589
L'Oreal S.A.
Process for dyeing human keratin fibers, having a lightening effect, comprising at least one fluorescent compound and compositions of the same
This invention relates to a process having a lightening effect for dyeing human keratin materials. The materials are contacted with a composition comprising, in a cosmetically acceptable medium, at least one fluorescent dye specified in the patent. The patent also relates to at least one fluorescent dye, to a composition comprising that fluorescent dye, and to a multi-compartment kit comprising the composition.
Marine Botanicals for Skin
7,303,753
Mary Kay Inc.
Compositions of marine botanicals to provide nutrition to aging and environmentally damaged skin
Methods and compositions comprising marine botanicals are disclosed for treating aged, mature, nutritionally-compromised or environmentally-damaged skin. These methods and compositions provide improvements in the skin's visual appearance, physiological functions, clinical properties and biophysical properties.
Temperature-changing Cosmetics
7,303,774
Coty B.V.
Relax cosmetic having a temperature effect
The present invention relates to new cosmetic relax preparations bringing about changing temperature effects on the skin. The cosmetic contains 0.1–10% by weight of an extract from Papaveraceae and 0.1–10% by weight of an extract from the above-ground parts of Menthae, along with 80–99.8% by weight of cosmetic auxiliaries, carrier substances, active agents or mixtures thereof.
Manipulating Hair
RE39,936
BASF Aktiengesellschaft
Crosslinked, water-soluble or water-dispersible polyurethanes
The present invention relates to crosslinked, water-soluble or water-dispersible polyurethanes of at least one polyurethane prepolymer containing terminal isocyanate groups and at least one polymer containing groups that are reactive toward isocyanate groups, chosen from hydroxyl, and primary and secondary amino- and/or carboxyl groups. These polymers have film-forming properties useful for setting, shaping and improving the structure of the hair.
