The present invention relates to a cosmetic process for treating keratin materials, in particular keratin fibers, preferably human keratin fibers such as the hair, using a) one or more direct dyes which are preferably neutral and b) one or more particular aliphatic ammonium salts, and to a composition comprising ingredients a) and b). The cosmetic process for treating keratin materials of the invention makes it possible to obtain a good color build-up up and, furthermore, the colors are vivid and chromatic.

The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in one or more steps, comprising the application to said keratin fibres of a composition comprising one or more compounds of formula (I) and/or (II), and also to the use thereof for dyeing keratin fibres, and to a device: in which formula (I) or (II) R.sub.1, R.sub.3, R.sub.4, R.sub.5, R.sub.6, and n are as defined in the description. The compounds of formula (I) according to the invention can give powerful, chromatic and sparingly selective colourings with good colour build-up, which are resistant to the various attacking factors to which keratin fibres may be subjected, such as inclement weather, light, washing and perspiration. ##STR00001##

The present invention is directed towards a composition, especially a cosmetic composition, in particular for coating keratin fibres such as the eyelashes, comprising: —at least one aqueous phase gelled with at least one synthetic polymeric hydrophilic gelling agent; and —at least one oily phase gelled with at least one lipophilic gelling agent chosen from meltable compounds, said oily phase also comprising at least one volatile oil; said phases forming therein a macroscopically homogeneous mixture, said composition comprising less than 10% by weight of non-volatile oil(s), relative to the total weight of the composition, said composition comprising from 10% to 70% by weight of volatile oil(s), relative to the total weight of the composition, said composition comprising a water content at least equal to 15% by weight relative to the total weight of the composition.

The present invention concerns an auxochrome substituent for an oxidative dye coupler. The auxochrome substituent enables ready developer reaction with the coupler to form azomethine and leuco dyes. Manipulation of the auxochrome substituent enables a bathochromic or hypsochromic shift of the light absorbance by the azomethine dye formed with the auxochrome substituted coupler.

This patent document discloses a kit containing abase component and an activating component for cosmetics, therapeutic and aesthetic application purposes. The kit, comprised innovative technology, ingredients, and formulations that overcome the drawbacks of unviable, unpractical, unwearable and unmarketable products, enables a film-formed “young-looking skin” to cling onto the real skin for much longer period of time, and is truly wearable and viable to the consumers for achieving the benefits of dramatically reducing or diminishing eye bags, dark circles, enlarged pores, wrinkles, age spots, and so on with desired and rapid results. The film is comfortable, invisible, safe, non-invasive and easy to wear.

The present invention relates to dissymmetric azomethine direct dyes of formula (I) and the leuco forms thereof of formula (II), and also to the use thereof for dyeing keratin fibres, in particular human keratin fibres such as the hair: ##STR00001##
