The present invention relates to a stable powder composition comprising hair direct dyes which is used for dyeing hair after mixing with one or more aqueous compositions. The composition comprises one or more direct dyes selected from HC Red 18, HC Blue 18, and HC Yellow 16, one or more alkanolamine as alkalizing agent, an organic and/or an inorganic pulverulent excipient.

The present invention relates to a method of coloring keratin fibers, especially human hair, which delivers intensive, long lasting, brilliant colors and provides improved grey coverage. Kit therefore is disclosed as well. The method of colouring hair involves treating hair prior to colouring with an alkaline reducing agent.

The present disclosure provides a two-component hair care agent including a first component and a second component. The first component and the second component are provided separately from one another. The first component or the second component has a color indicator showing a color change in a pH-value range of from about 3 to about 6, the first component has a pH value in a range of from about 2 to about 4and the second component has a pH value in a range of greater than about 4 to about 9. The present disclosure also provides a method for applying the two-component hair care agent and a method of using the two-component hair care agent.

The present invention is intended to provide an oily makeup cosmetic that is colorless in appearance but develops a color on application onto body surface, such as skin and lips. The present invention provides a colorless oily makeup cosmetic comprising (a) one or two dyes selected from Red No. 218 and Red No. 223, and (b) an oil agent, and a mixture of the component (a) and the component (b) at a mass ratio (a):(b) of 0.1:100 has a difference of 0.2 or less between the maximum absorbance and the minimum absorbance in a wavelength region of 500 to 600 nm. The oily makeup cosmetic may develop a color due to the component (a) on application onto body surface, such as skin and lips.

The present invention relates to a process for dyeing and relaxing curls of keratin fibres, such as the hair, which comprises the application to the fibres of one or more acidic compositions comprising reducing agents and of one or more compositions comprising hair-dyeing agents, and a step of heat treatment of the fibres by means of a heating tool. A subject of the invention is also the use of the composition(s) comprising reducing agents and of the composition(s) comprising hair-dyeing agents in a process for dyeing and relaxing curls of keratin fibres. Finally, a subject of the invention is a multi-compartment device or kit suitable for carrying out such a process.

The present disclosure relates to methods for coloring hair. The methods include applying an aqueous coloring composition and heat to the hair. The coloring composition includes water and one or more colorants for coloring the hair. After application of the aqueous coloring composition to the hair, the hair having the coloring composition applied thereon is heated to a temperature of about 100 C. to about 200 C. for a period of time, for example, for about 5 seconds to about 5 minutes. The methods are quick, efficient, and effective.

The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which said fibres are treated using one or more cosmetic compositions comprising a) one or more dyes chosen from synthetic direct dyes and dyes of natural origin, b) one or more titanium salts and b1) optionally one or more particular carboxylic acids, c) one or more cellulose-based polysaccharides, d) optionally one or more organic compounds that are liquid at 25 C., with a Hansen solubility parameter value H<16 (MPa).sup.1/2 at 25 C., e) optionally one or more chemical oxidizing agents such as hydrogen peroxide or one or more hydrogen peroxide-generating systems.

The invention relates to a composition comprising the combination of at least one fatty substance, the total content of fatty substance being greater than or equal to 30% by weight, relative to the total weight of the composition, at least one particular carboxylic acid and at least one oxidation dye and/or an alkaline agent.

The present invention addresses the problem of providing an -gel formation composition and an -gel composition that uses the -gel formation composition, wherein said compositions are highly stable, do not deposit crystals, become more viscous over time, and, when used in a preparations for external use, are refreshing during application and have high skin-moisturizing action after application. A gel composition that includes a polyoxyethylene dialkyl ester and/or a polyoxyethylene dialkyl ether, a polyoxyethylene alkyl ester and/or a polyoxyethylene alkyl ether, and, preferably, a polyoxyethylene sterol ether and water.

The present invention relates to a cleaning liquid, in particular a cleaning liquid for cleaning surfaces and/or for sanitizing water.
