L’Oreal
Compositions having improved soft focus effect properties
The invention relates to a composition, especially a cosmetic composition, containing at least one silicone elastomer and at least one encapsulated pigment, wherein the refractive index of the pigment is greater than the refractive index of the encapsulating material.
20070172438
July 26, 2007
Comestic preparation containing a metallic pigment
The invention relates to a cosmetic preparation containing a metallic effect pigment which consists of a metal substrate having a layer enclosing the substrate. Said layer is produced in a sol/gel method, has a barrier effect against sweat and saliva and prevents a direct contact between skin and metallic substrate, the metallic pigment being hydrophilic. The inventive preparation can be in the form of a cream, a lotion, an eyeshadow, a nail varnish, a lipstick, a mascara, a gel, a make-up formulation or a self-tanning cream or lotion.
Skin Lightening
7,250,158
Conopco, Inc.
Skin lightening agents, compositions and methods
Cosmetic compositions and methods, particularly for skin lightening, using a compound, preferably 4-hydroxyphenylpyruvate, and derivatives as specified in the patent as skin lightening agents alone or in combination with other skin benefit agents and together with a cosmetic vehicle.
Dye Composition
7,250,064
L'Oreal S.A.
Dye composition comprising at least one fluorescent dye and a non-associative thickening polymer for human keratin materials, process therefor, and method thereof
The disclosure relates to a composition comprising at least one fluorescent dye and at least one non-associative thickening polymer, to processes using such a composition, and to devices comprising such a composition. The disclosure also relates to processes and methods for dyeing human keratin materials, for example artificially dyed or pigmented hair and dark skin, with a lightening effect, using compositions comprising at least one fluorescent dye and at least one non-associative thickening polymer.
Extracts for Skin and Scalp
20070178059
August 2, 2007
Cognis Corp.
Cosmetic and pharmaceutical uses of an extract of a plant belonging to the genus Buchholzia
A cosmetic or dermopharmaceutical composition including an extract of a plant belonging to the genus Buchholzia and at least one auxiliary and/or additive is provided. A method for the cosmetic treatment of the skin or scalp and a method for the treatment of skin inflammation includes administering to a patient in need thereof a composition including an effective amount of a plant extract from a plant belonging to the genus Buchholzia.
Polymers
20070179245
August 2, 2007
Wacker Chemie AG
Method for production of mixed polymers containing silicon
Polymer dispersions of polymers derived from silicone macromers and ethylenically unsaturated monomers are capable of incorporating large amounts of chemically bonded macromer, when the silicone macromer and part of the unsaturated monomer are polymerized in aqueous medium as an initial charge with an oil-soluble initiator, and the remaining monomers are fed in and polymerized using a water-soluble initiator. The dispersions may be dried to form water-redispersible polymer powders.
20070172505
July 26, 2007
Cosmetic composition comprising at least one specific block copolymer
The present invention relates to a cosmetic composition comprising, in a physiologically acceptable medium: at least one aqueous phase, at least one preservative, and at least one block copolymer of rod-coil type comprising at least one coil polymeric block structure with a variable conformation covalently bonded to at least one rod polymeric block structure with a restricted conformation.
Microemulsion
20070172440
July 26, 2007
Transparent cosmetic microemulsion-based formulation containing an alpha-hydroxy-carboxylic acid
The invention relates to a clear, microemulsion-based cosmetic formulation with reduced stickiness, comprising at least one antiperspirant active ingredient and/or deodorant active ingredient and α-hydroxycarboxylic acid.
Polysaccharide
20070172441
July 26, 2007
Cation-modified purified galactomannan polysaccharide and cosmetic composition containing the substance
The present invention presents a cationic polymer. When a hair treatment composition containing the cationic polymer is used to damaged hair, excellent conditioning effects are shown. When a skin cosmetic treatment composition containing the cationic polymer, foam formation and foam quality are improved and good use feeling is obtained.
