Polyether-modified organopolysiloxane, diorganopolysiloxane-polyether block copolymer, their production methods, and cosmetic preparation
United States Patent 8034891
Publication Date: Oct. 11, 2011
Assignee: Dow Corning Toray Company, Ltd.

Disclosed are a novel polyether-modified organopolysiloxane and a novel diorganopolysiloxane-polyether block copolymer, which are more resistant to oxidation than the heretofore existing polyoxyalkylene-modified organopolysiloxanes and are thus more resistant to producing allergenically antigenic oxidation products during elapsed time in storage. Methods of producing this polyether-modified organopolysiloxane and diorganopolysiloxane-polyether block copolymer are also provided, as well as a cosmetic containing the modified organopolysiloxane or diorganopolysiloxane-polyether block copolymer.

Amphoteric ethyl methacrylate copolymers and use thereof
United States Patent 8034888
Publication Date: Oct. 11, 2011
Assignee: BASF SE

The present invention relates to amphoteric copolymers comprised of ethyl methacrylate, a possible N-vinyllactam compound, at least one monoethylenically unsaturated carboxylic acid and at least one compound with α,β-ethylenically unsaturated double bond and at least one cationogenic and/or cationic group in copolymerized form. Also disclosed are cosmetic and pharmaceutical compositions that comprise such copolymers, their preparation methods and the use of these copolymers.

Composition and methods for skin care
United States Patent 8034788
Publication Date: Oct. 11, 2011
Assignee: Dermipsor Ltd.

Compositions useful in the treatment of skin atrophy and improvement of skin appearance and texture are disclosed. The methods include the topical administration of vitamin D3 or specific vitamin D3 analogs as an essential ingredient either on its own or in combination with cADPR and/or nicotinamide. The compositions are particularly effective in preventing and treating signs of chronological and or photoaging including fine lines, wrinkles and discoloration.

Adsorptivity imparting agent containing porous silica
United States Patent 8034740
Publication Date: Oct. 11, 2011
Assignee: Taiyo Kagaku Co., Ltd., Kabushiki Kaisha Toyota Chuo Kenkyusho

This patent details a moisture- or protein-adsorbability imparting agent, comprising a porous silica with a hexagonal pore structure, an average pore size of from 0.8-20 nm, an average particle size of 50-100 μm, a specific surface area of 400-2000 m2/g and a pore volume of from 0.1 to 3.0 cm3/g.

This agent can be used for imparting absorbability of moisture or a protein to a material selected from the group consisting of food wrapping materials; filtration aid agents; sanitary articles; compositions containing a synthetic resin; moisture-controlled material; covering materials for wounds; insulation substrates; coating materials for semiconductor devices; cosmetics; inkjet recording media; and compositions containing synthetic fibers.

Polyurethane dispersions based on polycarbonate polyols and suitable for use in personal care products
United States Patent 8034322
Publication Date: Oct. 11, 2011
Assignee: Bayer MaterialScience LLC and Bayer MaterialScience

The invention relates to aqueous polyurethane dispersions, to a process for preparing them and to their use in cosmetic applications such as hair fixatives. Polyurethane dispersions have recently been incorporated into cosmetic products, such as hair fixatives, suntan lotions, etc., offering several advantages over conventional technologies such as acrylics and acryl amide copolymers, polyvinyl pyrrolidone, and PVP/VA copolymers. Such advantages include water compatibility, ease of formulating low VOC sprays, water resistance and excellent film forming ability. Specifically in hair care products, polyurethane dispersions provide great setting effect without sticky feel, excellent style retention owing to the polymer's elastic memory, natural look and feel. All these attributes are highly valuable to the consumer. Commercial polyurethane dispersions designed as hair fixatives and hair styling polymers generally exhibit good high humidity curl retention, style retention, good feel and shine. However, their lack of adhesion to hair is demonstrated by extensive flakiness on hair after combing. This creates a significant aesthetic problem for consumers.

Compositions comprising organosilicones
WIPO Patent Application WO/2011/123739
Publication Date: Oct. 6, 2011
Assignee: The Procter & Gamble Company, RK Panandiker, LA Zannoni, SD Smith and RJ Mcchain

The present application relates to compositions such as consumer products comprising organosilicones, as well as processes for using such compositions. Such compositions comprising such organosilicones are easier to formulate, an provide more economical and superior care benefits when compared to current silicone containing compositions.

Care polymers
WIPO Patent Application WO/2011/123736
Publication Date: Oct. 6, 2011
Assignee: The Procter & Gamble Company, RK Panandiker, LA Zannoni, SD Smith and RJ Mcchain

The present application relates to care agents, for example care polymers, and compositions such as consumer products comprising such care agents, as well as processes for making and using such care agents and such compositions. The performance of the care polymers that applicants teach, can be further increased by following the emulsification teaching of the present specification and/or combining such care polymers with silicone materials.

Permeable mixtures, methods and compositions for the skin
WIPO Patent Application WO/2011/123619
Publication Date: Oct. 6, 2011
Assignee: Penguin IP Holdings Inc. and J Bartels

This patent discusses topical mixtures with ranges of permeability that promote dermal healing, wound stage arrest, skin cooling, and patient comfort through pH adjustment, therapeutic ingredient carriage, water and oxygen delivery, with superior aesthetics and ease of cleaning features.

Makeup Cosmetic
WIPO Patent Application WO/2011/122087
Publication Date: Oct. 6, 2011
Assignee: Shiseido Company, Ltd. and S Oohashi

Disclosed is a makeup cosmetic that has no product unevenness even if coloring is good, the cosmetic is long lasting, removal is favorable and the tactile feel is highly elastic. The makeup cosmetic is characterized by containing: a silicone gel containing a cross-linked polyether-modified silicone and a silicone oil; an oil; and a powder. Preferably, a gel containing 20-30% w/w cross-linked polyether-modified silicone and 70-80% w/w silicone oil is used as the aforementioned silicone gel.

Arginine derivative and cosmetic containing the same
US Patent Application 20110245344
