Composition for dyeing the hair, comprising a heterocyclic oxidation base and a 2-amino-5-ethylphenol coupler The present invention relates to a composition for dyeing keratin fibres, comprising a particular heterocyclic oxidation base and a 2-amino-5-ethylphenol coupler. The invention also relates to a process for dyeing keratin fibres using this composition. Finally, the invention relates to the use of such a composition for dyeing keratin fibres, and in particular the hair.

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

(1) mixing one or more organic C.sub.1-C.sub.6 alkoxy silanes with water,
(2) optionally adding one or more cosmetic ingredients to the mixture obtained in step (1),
(3) storage of the mixture for a period of at least 5 days,
(4) if necessary, addition of one or more cosmetic ingredients to the stored mixture,
(5) partial or complete removal from the mixture of the C.sub.1-C.sub.6 alcohols released in steps (1) to (4).

The present invention relates to a hair coloring composition based on natural ingredients and with a separate alkalizing agent, which can be used both in direct coloring and oxidative coloring and related coloring kit.

According to one aspect of the present disclosure, provided is a film for hair dyeing comprising: a base film; and an ink layer for hair dyeing on the base film, wherein the ink layer for hair dyeing comprises a first pigment for masking hair color, a second pigment for expressing desired color on hair, a resin, and wax. According to one aspect of the present disclosure, provided is a printer for hair dyeing comprising: a body including a printer head; and a film cartridge for hair dyeing mounted to the body over the printer head; wherein the printer head may be in contact with a film included in the film cartridge for hair dyeing and comprises a hair holder of which one end is connected to one end of the body so as to be folded and unfolded with respect to the body. The hair may be grabbed between the body and the hair holder, and the printer head may be positioned on a side facing the hair holder.

The subject of the present disclosure is a composition for coloring keratinous material, in particular human hair, containing in a cosmetic carrier (a) at least one organic silicon compound selected from silanes having one, two or three silicon atoms, said organic silicon compound further comprising one or more basic chemical functions and one or more hydroxyl groups or hydrolysable groups per molecule, (b) at least one colorant compound from the group of pigments and/or direct dyes, and (c) at least one film-forming hydrophilic polymer.

The present disclosure concerns a cosmetic product for modifying the natural color of keratinous fibers, in particular human hair, comprising at least one packaging (VP) and a cosmetic composition (KM) contained in this packaging (VP). The packaging is made of a multi-layer film (F) comprising at least two polymer layers (P1) and (P2) and at least one barrier layer (BS). The cosmetic composition comprises at least one oxidizing agent, at least one C.sub.8-C.sub.30 alcohol, at least one anionic surfactant and at least one non-ionic surfactant. The use of the packaging (VP) in combination with the cosmetic composition (KM) does surprisingly not lead to a swelling of the packaging or excessive water loss of the composition (KM) during storage.
