7,273,058
Wella AG
Method for simultaneously dyeing and permanent shaping of hair
The disclosed method for simultaneously dyeing and permanent shaping of hair includes winding hair strands onto curlers; mixing a) a dye component containing 1–10% by weight of one or more dye compound and an amount of a keratin-reducing substance with b) a shaping component containing 6–15% by weight of the keratin-reducing substance in a weight ratio of from about 1:1 to 1:10 to form a dyeing and shaping composition, which necessarily contains 5–18% by weight of the keratin-reducing substance; then allowing the hair with the dyeing and shaping composition to act on the hair for an acting time sufficient for permanent shaping. After that, the method involves allowing a fixing composition to act on the hair for 1–40 min and subsequently rinsing the hair. The dye component contains 4,5-diaminopyrazole derivatives and certain aminophenol derivatives.

Gingko Biloba for Sun Care
20070224138
The Proctor & Gamble Company
Cosmetic composition comprising gingko biloba and sunscreen agents
A cosmetic composition is provided comprising a Gingko biloba extract, an alkyl β,β-diphenylacrylate and/or α-cyano β,β-diphenylacrylate derivative, and a dibenzoyl methane derivative. A cosmetic use of that composition is also provided for preventing sun damage and photo aging.

Microspheres
20070224140
L’Oreal
Cosmetic or dermatologic compositions containing microspheres
The compositions of this invention comprise a microsphere and a film-forming component. Such compositions possess improved cosmetic or dermatologic properties and characteristics such as increasing eyelash length and/or volume, improving the hold of the shape or curl of hair/eyelashes, permitting hair or eyelashes to be reshaped into the original style without reapplying a hair or eyelash styling composition and/or heat, or increasing transfer-resistance, waterproofing and/or long-wear properties.

Foam Carrier
20070224143
Kamedis Ltd.
Cosmetic and pharmaceutical foam carrier
The invention provides a quick-break, alcohol-free, cosmetic and pharmaceutical foam carrier comprising approximately 20–60% hydrophobic volatile solvent, approximately 20–60% water, approximately 3–20% of polyol, and approximately 0.1–7.5% of a surface active agent. The carrier is suited for inclusion in both water-soluble and oil-soluble cosmetic agents.

UV Protection from Merocyanine Sulfone Derivatives
20070224147
L’Oreal
UV-photoprotecting/sunscreen compositions comprising silane/siloxane derivatives of merocyanine sulfones
Topically applicable cosmetic compositions useful for the UVA photoprotection of the skin and/or hair contain effective amounts of at least one silane, siloxane or polysiloxane merocyanine sulfone having at least one of three structural formulae specified in the patent application.

Block Polymer
20070224151
L’Oreal
Cosmetic composition comprising at least one specific block copolymer
The present invention relates to a cosmetic composition comprising, in a physiologically acceptable medium, the following components: at least one fatty phase, 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. The polymers considered in the present invention are easily applied to the hair and, surprisingly, exhibit a satisfactory styling ability and are easily removed with a simple shampoo. Brushing the treated hair does not result in a powdering effect but leaves the hair soft, glossy and nontacky.
