The present disclosure relates to hair-coloring compositions comprising direct dyes, and aerosol hair-coloring products comprising the hair-coloring compositions. The hair-coloring compositions include: (a) at least one direct dye selected from nitro-phenylenediamines, nitro-aminophenols, azo dyes, anthraquinones, triarylmethane dyes, indophenols, and a mixture thereof; (b) at least one nonionic film forming polymer; (c) at least one thickening agent; (d) at least 40 wt. % of water, based on the total weight of the compositions; and (e) 40 wt. % or less of ethanol, based on the total weight of the composition. The hair-coloring compositions can be combined with a propellant and incorporated into a canister to provide a hair-coloring aerosol product. The compositions and aerosol products are useful for coloring hair.

The present invention relates to novel cationic 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: (I) (II) in which formula (I) or (II) X.sub.1, X.sub.2, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, n 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.

The object of the present disclosure is a method for dyeing human hair which is adapted to the differing degrees of damage along the length of the hair fiber and achieves more homogenous coloring results.

The present disclosure relates to agents for the oxidative coloring of keratinic fibers, which are characterized in hat they contain derivatives of anisole as novel developer molecules.

The present invention relates to a composition for dyeing keratin fibres, in particular keratin fibres such as the hair, comprising: at least one oxidation base 3-(2,5-diaminophenyl)-1-propanol and/or acid salts thereof and/or solvates thereof such as hydrates; at least one particular coupler; optionally at least one fatty substance; optionally at least one basifying agent; and optionally at least one chemical oxidizing agent. The invention also relates to a process for dyeing keratin fibres such as the hair using the composition of the invention, and to a multi-compartment device for using the composition of the invention.

A mixture, comprising at least three, two or four different chemical compounds, selected from the group eicosapentaenoic acid, usnic acid, norspermidine, clove oil and 10-undecynoic acid is used in dental health compositions. The mixture is used for dental hygiene for controlling Streptococcus mutans and Candida albicans.

The present invention features novel cosmetic skin care compositions for improving the appearance of flushed or rosacea-affected skin.

The invention relates to a composition comprising at least one oxidation coupler chosen from hydroxyethyl-3,4-meth-ylenedioxyaniline 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 oxyethylenated C.sub.8-C.sub.30 fatty acid ester of sorbitan having from 1 to 10 ethylene oxide units. The invention also relates to a process for N dyeing keratin fibres, preferably the hair, comprising the application of the composition to said keratin fibres.

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 presently claimed invention relates to a method for obtaining crystalline diethylamino hydroxybenzoyl hexyl benzoate. Further, the presently claimed invention relates to crystalline diethylamino hydroxybenzoyl hexyl benzoate obtained by the method and to a cosmetic composition comprising crystalline diethylamino hydroxybenzoyl hexyl benzoate. The crystalline diethylamino hydroxybenzoyl hexyl benzoate obtained by the method of the presently claimed invention has a phthalic acid dihexyl ester (PSDHE) content in the range of 1 to 250 ppm.
