Patent Picks by Bud Brewster

Patents and intellectual property are vital to building and growing a business but during the creative formulating process it is nearly impossible to research every patent that is issued. Cosmetics & now features collections of recently issued patents for your consideration and convenience. Chosen by our technical editor, Bud Brewster, for their relevance to personal care, these "Patent Picks" are taken from publicly available sources, collected and presented here for your convenience.

Schott AG
Cosmetic, personal care, cleaning agent, and nutritional supplement compositions and methods of making and using same
The present invention involves new cosmetic, personal care, cleaning agent, biocidal agent, functional food and nutritional supplement compositions. These new compositions incorporate bioactive glass into cosmetics, personal care items, cleaning agents, biocidal agents, functional foods, and nutritional supplements. The present invention also involves methods of making and methods of using such compositions.

L'Oreal S.A.
Compositions comprising at least one ester of at least one hydroxylated aliphatic compound
Compositions comprising at least one ester which comprises at least one aromatic group, which is liquid at room temperature and which is derived from esterification with: (i) at least one aromatic acid of (ii) at least one hydroxyl group of at least one hydroxylated aliphatic compound chosen from hydroxylated aliphatic acids and esters of hydroxylated aliphatic acids, wherein said at least one hydroxyl group is chosen from pendant hydroxyl groups and terminal hydroxyl groups. The inventive compositions may be used for, for example, making up the face, body or superficial body growths of human beings and may constitute, for example, a lipstick, a lip gloss, a tattooing product, an eye shadow, a mascara, a product for caring for the hair or a nail varnish.

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
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
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
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.

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.

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.

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.

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.
