Composition comprising at least two anionic surfactants, a nonionic surfactant, an amphoteric surfactant, and at least one direct dye The present invention relates to a composition for the cosmetic treatment of keratin fibres, in particular of the hair, comprising at least two anionic surfactants, at least one nonionic surfactant, at least one amphoteric surfactant and at least one direct dye. The invention also relates to a cosmetic process for treating keratin fibres, especially for dyeing the hair, using such a composition, and also to a use of said composition.

The subject of the present disclosure is a process for dyeing keratinous material, in particular human hair, comprising the following steps: Application of an agent (a) to the keratinous material, wherein the agent (a) comprises: (a1) at least one organic silicon compound selected from the group of silanes having one, two or three silicon atoms, and (a2) at least one colorant compound selected from the group of pigments and/or direct dyes, and Application of an agent (b) to the keratinous material, wherein the agent (b) comprises: (b1) at least one film-forming polymer.

The present invention is directed to a non-oxidative dyeing composition, method, and use for hair. The composition comprises certain direct dyes, fatty alcohols, surfactants, and a buffer system.

A cosmetic composition for improved dyeing of keratin fibers is described. The composition comprises alkoxylated organopolysiloxanes and alkoxylated glyceryl esters and/or optionally alkoxylated alkyl glyceryl ethers. The composition may comprise less than 40 wt % water, or may be anhydrous. The composition may further comprise a direct dye, and may be used for bleaching, lightening, or dyeing of keratin fibers.

Disclosed are hair-colouring compositions comprising an oxidative dye and an alkalising agent consisting of isopropanolamine and a malic acid diester. The compositions according to the invention, due to synergic effects between isopropanolamine and the malic acid diester, are advantageous, because they lighten the hair by up to four levels, do not have an unpleasant odour, and limit the damage caused to the hair, maintaining its integrity and consequently its natural characteristics of elasticity, shine and combability.

Provided are methods of treating hair, the method comprising: contacting the hair with a mixture comprising: i. an ionic liquid comprising an imidazolium-based compound or ammonium-based compound, and ii. an anionic surfactant. In certain methods, the mixture further comprises a cationic direct dye.

The subject of the present disclosure is a process for dyeing keratinous material, in particular human hair, comprising the following steps: Application of an agent (a) to the keratinous material, wherein the agent (a) comprises: (a1) at least one organic silicon compound selected from the group of silanes having one, two or three silicon atoms, and (a2) at least one derivative of alkylated silanol, and application of an agent (b) to the keratinous material, wherein the agent (b) comprises: (b1) at least one sealing reagent,wherein at least one of the agents (a) and (b) further comprises at least one colorant compound selected from the group of pigments and/or direct dyes.

Also disclosed are multi-component packaging unit (kit-of-parts) for dyeing keratinous material.

A process is provided for dyeing keratinous material. The process includes (1) providing an agent (a) that includes (a1) at least one amino-functionalized silicone polymer and (a2) at least one colorant compound. The process further includes (2) providing an agent (b) that includes (b1) water and (b2) at least one fat component. The method includes (3) preparing an application mixture by mixing agents (a) and (b) and (4) applying the application mixture to the keratinous material. Further, the method includes (5) exposing the application mixture to the keratinous material and (6) rinsing the application mixture with water.

A process for dyeing keratinous material is disclosed. The process includes applying an agent (a) and an agent (b) to the keratinous material. The agent (a) comprises (a1) at least one organic silicon compound, and (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound. A multi-component packaging unit is also disclosed, and comprises, separately packaged, a first container comprising an agent (a′), a second container comprising an agent (a″), and a third container comprising an agent (b). The agent (a′) comprises (a1) at least one organic silicon compound. The agent (a″) comprises (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound.

The present invention is directed to a dyeing composition, method, use and kit thereof, which improves dyeing using specific direct dyes. The inventive composition comprises benzyl alcohol, and a thickening polymer.
