A dyeing composition for keratin fibers, including one or more first direct dyes selected from HC Blue 18, HC Red 18, HC Yellow 16, and salts thereof, one or more second direct dyes selected from Disperse Black 9, Acid Yellow 1, 2-amino-6-chloro-4-nitrophenol and salts thereof, and one or more alkalizing agents.

It is provided a kit for obtaining a hair coloring composition, a hair coloring composition, and a method for treating hair. The hair coloring composition particularly provides the desired color shade and intensity, together with an enhanced root to tip evenness on hair, particularly on previously colored hair and on hair with a broad range of damage levels along hair length.

The present invention relates to a composition, in particular a cosmetic or dermatological composition, comprising: a) at least one merocyanine corresponding to formula (3) below, and also the geometric isomer forms, notably the E/E- or E/Z-geometric isomer forms, thereof:

##STR00001## in which: A is O or NH; R is a C.sub.1-C.sub.22 alkyl group, a C.sub.2-C.sub.22 alkenyl group, a C.sub.2-C.sub.22 alkynyl group, a C.sub.3-C.sub.22 cycloalkyl group or a C.sub.3-C.sub.22 cycloalkenyl group, it being possible for said groups to be interrupted by one or more O; and b) at least one compound chosen from suitably selected gamma-butyrolactones and gamma-butyrolactams.

The present invention also relates to a non-therapeutic cosmetic method for caring for and/or making up a keratin material, comprising the application, to the surface of said keratin material, of at least one composition as defined above.

The invention relates to a composition comprising at least one oxidation coupler chosen from 6-hydroxybenzomorpholine of formula (I), one of its addition salts, its solvates and/or the solvates of its salts, at least one oxidation coupler chosen from 2-amino-5-ethylphenol of formula (II), one of its addition salts, its solvates and/or the solvates of its salts, and at least one compound chosen from N, N-dicarboxymethyl glutamic acid, one of its salts, and mixtures thereof. The invention also relates to a process for dyeing keratin fibres, preferably the hair, comprising the application of the composition to said keratin fibres.

The present disclosure relates to hair coloring base compositions and ready-to-use hair coloring compositions comprising 2-methoxymethyl-P-phenylenediamine, an oxidative dye precursor. The hair coloring base composition is mixed with a developer composition to form a ready-to-use hair coloring composition. These compositions are effective for coloring or toning hair. The color imparted to the hair is long-lasting (tenacious), neutralizing, and gentle. Methods for making the composition and methods for coloring hair are also disclosed.

Disclosed are fragrance accords each containing (i) at least 7 wt % of one or more Class 1 fragrance ingredients, (ii) 5 to 85 wt % of one or more Class 2 fragrance ingredients, and (iii) 0 to 80 wt % of one or more Class 3 fragrance ingredients. The Classes 1, 2, and 3 fragrance ingredients are defined by experimental velocity. Also disclosed are delivery systems and consumer products containing such a fragrance accord.

Cosmetic and dermatological compositions, including color changing compositions, are provided which typically include a plurality of synthetic particles having a size in the micrometer or nanometer range. Each synthetic particle typically includes one or more aggregates of a pigment selected from phenoxazone, phenoxazine, and a derivate or precursor thereof, and a stabilizing material which has a refractive index larger than 1.45; the aggregates having a size larger than about 100 nm and the composition being biodegradable and biocompatible.

The present invention relates to a composition for the simultaneous bleaching and dyeing of keratin fibres, comprising at least one chemical oxidizing agent, at least one (bi)carbonate, at least one silicate and at least one oxidation dye, and also to a process for the simultaneous bleaching and dyeing of keratin fibres using this composition.

The invention relates to a composition comprising at least one oxidation base chosen from 2-methoxymethyl-para-phenylenediamine of formula (I), one of its addition salts, its solvates and/or the solvates of its salts, at least one oxidation coupler chosen from 6-hydroxybenzomorpholine of formula (II), one of its addition salts, its solvates and/or the solvates of its salts, at least one amphoteric or zwitterionic surfactant, and at least one solid fatty substance. The invention also relates to a process for dyeing keratin fibers, preferably the hair, comprising the application of the composition to said keratin fibers.

The invention relates to a composition for dyeing human keratin fibers, preferably the hair, comprising:one or more anthraquinone cationic direct dyes,one or more polyols,one or more anionic surfactants, andone or more nonionic polysaccharides.
