Patent Picks—Azo Quinolinium, Permanent Waving, Anionic Surfactants, Cassia Derivatives and More for Hair Care

Azo quinolinium compounds comprising a disulphide/thiol unit, compositions containing same, process for dyeing keratin fibres and device
European Patent EP2201070
Publication Date: Nov. 09, 2011
Assignee: L'Oréal

The present invention relates to thiol/disulphide azo quinolinium compounds for dyeing keratin fibres. It is a known practice to dye keratin fibres, and in particular human keratin fibres such as the hair, with dye compositions containing direct dyes. These compounds are colored or coloring molecules which have an affinity for the fibres.

It is known practice, for example, to use direct dyes of the nitrobenzene type, anthraquinone dyes, nitropyridine dyes, or dyes of the azo, xanthene, acridine, azine or triarylmethane type. These dyes are normally applied to the fibres, optionally in the presence of an oxidizing agent, if it is desired to obtain a simultaneous lightening effect on the fibres. Once the leave-on time has elapsed, the fibres are rinsed, optionally washed and dried. The colorings, which result from the use of direct dyes, are temporary or semi-permanent colorings since the nature of the interactions which bind the direct dyes to the keratin fibre, and their desorption from the surface and/or from the core of the fibre, are responsible for their weak dyeing power and their relatively poor resistance to washing and perspiration.

In order to increase the fastness of direct colourings, it is known practice to use disulphide dyes. However, some disulphide dyes have performance levels that are insufficient in particular in terms of selectivity, uptake, stability or resistance to outside attacks such as bad weather, shampooing operations, light or sweat, which brings about a change in color over time. Color change is a particularly embarrassing problem when it occurs after shampooing and/or exposure to light.

The aim of the present invention is therefore to provide disulphide or thiol dyes that do not have the drawbacks of existing direct dyes. In particular, one of the aims of the present invention is to provide dyes which make it possible to obtain natural shades which are resistant to outside attacks and which do not change color over time. This aim is achieved with the present invention, a subject of which is a process for dyeing keratin materials, in particular human keratin materials such as the hair, which comprises applying, to the keratin materials, a dye composition comprising, in a suitable cosmetic medium, at least one disulphide or thiol azo quinolinium dye and also the addition salts thereof with an organic or mineral acid, and the solvates, hydrates, tautomers and optical and geometrical isomers thereof.

Hair cosmetic composition
European Patent EP2194963
Publication Date: Nov. 9, 2011
Assignee: Kao Corp.

The present invention provides a hair cosmetic composition containing: one or two or more peptides each having the number of amino acid residues between 5 and 50, and having neither a sulfur-containing amino acid residue nor a derivative thereof; and a hair-swelling organic solvent. Further, the present invention provides a hair treatment method in which the above-described hair cosmetic composition is applied to the hair. 

The present invention relates to a hair cosmetic composition capable of repairing the hair damaged by various external factors and a method for repairing the hair by using the hair cosmetic composition. The present inventors discovered that some specific peptides are satisfactory in penetrability into hair and the use of such peptides in a hair cosmetic composition, together with an organic solvent to swell the hair, attains a remarkable damage repairing effect.

Composition for the permanent shaping of human hair
European Patent EP2014334
Publication Date: Nov. 9, 2011
Assignee: KPSS-Kao Professional Salon Services GmbH

The present invention concerns a composition for the permanent shaping of human hair used both for the permanent waving of human hair with a waving effect as well as for the straightening of either naturally or chemically curled hair.

It is generally known that permanent waving is carried out in two steps, the reductive splitting of the cysteine disulfide bonds in the hair by a reducing agent, and the subsequent neutralization by application of an oxidizing agent, whereby the cysteine disulfide bonds are restored. The reducing agent still most frequently used today is thioglycolic acid, also in form of the salts thereof, in particular its ammonium salt, although numerous other thio compounds have been proposed for this purpose, which, however, mostly did not succeed.

The compositions containing thioglycollates are customarily applied at a pH 7–10, specifically 8.5 and 9.5. Such compositions vary in their waving and/or straightening performance and, therefore, there is still need for further improvement. The present invention starts from the task of providing a composition for the permanent shaping of human hair with waving and straightening performance. For waved hair, it is especially important that the hair has elasticity and bounce

Anhydrous Foam Comprising Silica
WIPO Patent Application WO/2011/135543
Publication Date: Nov. 3, 2011,
Assignee:  L'Oréal, P Ilekti and V Jacques

The present invention relates to an anhydrous cosmetic composition in the foam form intended in particular for caring for and/or making up keratinous substances and more particularly the lips, being composed predominantly of fatty substances. The present invention relates to an anhydrous cosmetic composition in the foam form that is comprised of: 10-50% w/w of at least one pasty fatty substance, 4-20% w/w of at least one wax, 40-70% w/w at least one nonvolatile oil and 3-15% w/w silica. The silica is present in the form of particles exhibiting a mean size of greater than or equal to 0.5 μιη and preferably less than 100 μm.

The present invention also relates to the associated method for caring for and/or making up keratinous substances. In addition, it relates to a product for making up and/or caring for keratinous substances. Cosmetic products in the foam form, also known as whipped compositions, exhibit a light and aerated texture. This novel texture renders them particularly pleasant to use, due especially to their particular feel, and is therefore highly appreciated by consumers. However, such compositions have to be stored at low temperature in a refrigerated environment in order to retain their texture. This is because, above 30°C, whipped compositions become unstable, in other words they lose their texture.

Cosmetic composition including an acanthus extract, and use of acanthus in a cosmetic hair-care composition
United States Patent Application 20110268686
Publication Date: Nov. 3, 2011,
Asssignee: Pierre Fabre Dermo-Cosmetique

The present invention relates to the utilization of acanthus in the cosmetic field, specifically in a hair care composition for creating and/or maintaining the curling effect. The acanthus, or Acanthus sp., is a large, attractive, hardy plant belonging to the Acanthaceae family. It is mainly found in Mediterranean Europe and in North Africa. It is usually grown as an ornamental plant. Its highly decorative leaves were much used by the Greeks as the model for decorative friezes ornamenting Corinthian-capital columns. The fresh leaves and roots have been used since antiquity for their medicinal properties. Since antiquity, its sap has had the reputation of being a stimulating tonic. Topically it was reputed to be soothing and emollient (burns, fractures, mouth problems). Nowadays its use is relatively limited; it is still used in homeopathy for treating cough.
