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.

The present invention relates to hair coloring and/or bleaching compositions that can be applied at less aggressive pH environment using relatively low oxidizing agent amounts, as well as their kits and methods thereof. The compositions exhibit low odor and substantially reduced hair fiber damage, are compatible with current dyes and dye precursor systems and result in excellent dye deposition with substantially no lift.

The invention relates to a composition for dyeing and/or lightening human keratin fibers, preferably the hair, comprising: one or more anthraquinone cationic direct dyes, at least 25% of one or more fatty substances, one or more chemical oxidizing agents, one or more basifying agents and/or one or more oxidation dye precursors, preferably one or more oxidation dye precursors.

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

This invention relates to a hair care composition that contains at least one hair care ingredient and at least one polymeric colorant. The invention also relates to a method for coloring human head or facial hair comprising the following steps: (a) providing a hair care composition that contains at least one poly(alkyleneoxy) substituted chromophore colorant; (b) applying the hair care composition to hair; and (c) allowing the hair care composition to contact the hair for a period of time.

The disclosure relates to compositions for use before, during, and/or after the hair is subject to a process for altering the color thereof. The compositions comprise a combination of citric acid and at least one urea compound. The compositions provide strength and other benefits to treated hair. The disclosure also relates to methods of using the compositions as well as kits comprising the compositions.

The instant disclosure relates to hair coloring base compositions and developer compositions that can be incorporated into a hair color cartridge, which combines the compositions and dispenses them onto hair. The hair color cartridge includes: (a) one or more hair coloring base compositions and; (b) one or more developer compositions, which can be combined to form an active hair coloring composition and dispensed onto hair. The hair coloring base compositions typically include one or more oxidative dye precursors; one or more alkalizing agents; one or more reducing agents; optionally, one or more cationic conditioning polymers; one or more surfactants; one or more water-soluble solvents; and water. The developer compositions typically include one or more oxidizing agents; one or more surfactants; and water. The unique components and fluid characteristics of the various compositions are such that devices or appliances comprising them accurately combine and dispense the hair coloring base composition(s) with the developer composition(s) in a predetermined ratio with excellent consistency for application to hair.
