A method of colouring an eyebrow, the method comprising: (I) applying to the eyebrow a colouring composition comprising: (a) one or more dye compounds selected from Acid yellow (23), Food Red (17), Acid Blue (9) and Acid Green (25); (b) an organic acid; (c) an alkylene carbonate; (d) an alcohol; and (e) glycerol and/or urea

The present invention concerns a cosmetic method for dyeing or making up keratin fibres, in particular eyelashes and/or eyebrows and preferably eyebrows, comprising the application, to the keratin fibres, of at least: a) A dyeing cosmetic composition A comprising, in a physiologically acceptable medium, one or more natural dye(s) chosen from the group consisting of neoflavonoids, gallic tannins and catechic tannins, and/or proanthocyanidins and the derivatives of same and the mixtures thereof, or preferably one or more plant extracts containing same, and advantageously an antioxidant, b) A revealing cosmetic composition B comprising, in a physiologically acceptable medium, at least one iron salt and/or one aluminium salt, in particular an iron gluconate or an iron sulphate, composition A being applied before or after composition B, and preferably before composition B.

A hair dye that is safe for human bodies and has a high hair dyeing effect is provided. The hair dye consisting of: a reaction solution (A) comprising: a substance having a specific flavonoid skeleton represented by the following general formula (1); one type or two or more types selected from benzyl alcohol, vanillin, propylene carbonate, and γ-butyrolactone; and one type or two or more types selected from a thioglycolic acid salt, a thiolactic acid salt, cysteine and cysteamine, and a reaction solution (B) comprising an oxidizing agent. ##STR00001##
(In the formula, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.6, and R.sub.7 independently represent a hydrogen atom, a hydroxy group, or a methyl group; either one or both of R.sub.6 and R.sub.7 is/are a hydroxy group; R.sub.5 represents a hydrogen atom, a hydroxy group, a galloyl group, or a saccharide; and X represents >CH.sub.2, >C═O, or >CHOH.)

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.

This invention relates to an oxidative hair cream composition that contains at least one oxidative hair cream ingredient and at least one thiophene azo colorant.

The subject of the present disclosure is a process for the preparation and storage of an agent for the treatment of keratinous material, in particular human hair, comprising the following steps:

(1) mixing one or more organic C1-C6 alkoxy silanes with water,
(2) optionally, partial, or complete removal from the reaction mixture of the C1-C6 alcohols liberated by the reaction in step (1),
(3) if necessary, addition of one or more cosmetic ingredients,
(4) filling of the preparation into a packaging unit, and
(5) storage of the preparation in the packaging unit,
wherein at least one of steps (1), (2), (3), (4) and/or (5) is carried out under an atmosphere having a water vapor content of less than about 10 g/m.sup.3.

It is provided herewith a hair treating product comprising an oxidizing component and a tint component; a hair treating composition obtained upon mixing of the oxidizing component and the tint component; the use of the oxidizing component in a hair treating product, for cancelling the alkalinity of a tint component; and an oxidizing component comprising a buffer system. The hair treating product, and the corresponding hair treating composition, is particularly useful for colouring or bleaching hair. It is useful for providing permanent or demi-permanent coloration or bleaching to keratin fibers.

A composition for dyeing keratin fibres comprising a. at least one azomethine compound selected from compounds (3) and (4) and b. water. The composition may be used in a process for dyeing keratin fibres or, with simultaneous or sequential application of a composition comprising one or more oxidising agents, in a process for lightening keratin fibres. ##STR00001##

This invention relates to an oxidative hair cream composition that contains at least one oxidative hair cream ingredient and at least one polymeric colorant.
