Agents for coloring keratinous fibers and methods of dying human hair are provided herein. In an embodiment, an agent is provided for coloring keratinous fibers. The agent is included in a cosmetic carrier and includes at least one non-ionic direct dye and at least about 0.1 wt. %in relation to the entire agentof one or several polyols.

A first agent for oxidation hair dye contains a carbonate, the first agent including (A) at least one selected from resorcin and its derivatives, and salts thereof, an upper limit of a compounding amount of the component (A) being 0.2% by mass or less, (B) at least one coupler selected from m-aminophenol, 5-amino-o-cresol, and -naphthol, and (C) 0.01 to 0.45% by mass of at least one dye intermediate selected from p-phenylenediamine, toluene-2,5-diamine, p-aminophenol, N,N-bis(2-hydroxyethyl)-p-phenylenediamine, and derivatives thereof, and salts thereof, a mass ratio of a content of the component (B) to a content of the component (A) being 0.5 to 10.

The present disclosure relates to compositions for altering the tone or color of the hair, the compositions comprising at least one amino acid, at least one carboxylic acid, monoethanolamine, and at least one hair coloring agent comprising a direct dye. The disclosure also relates to methods of using the compositions.

A hair dye composition containing a carbonate also includes (A) at least one selected from resorcin and its derivatives, and salts thereof, an upper limit of a compounding amount of the component (A) being 0.2% by mass or less, and (B) at least one dye selected from 5-(2-hydroxyethylamino)-2-methylphenol, 1,5-dihydroxynaphthalene, and a nitro dye.

The present invention relates to a packaging article comprising: i) an envelope defining at least one cavity, the envelope comprising water-soluble and/or liposoluble fibres; ii) at least one anhydrous dye composition containing at least one direct dye; and iii) optionally at least one anhydrous oxidizing agent; it being understood that the dye composition ii) and the anhydrous oxidizing agent iii), when it is present, are in one of the cavities defined by the envelope i). Another subject of the invention is the use of the said article for dyeing keratin fibres and a process for dyeing keratin fibres using the said article. The use of the packaging article makes it possible to obtain dye compositions whose consistency is pleasant on use, which are easy to apply and which make it possible to obtain powerful colouring of the hair.

A hair coloring method may include a step of applying a mixture of the following (A) and (B) in a predetermined ratio: (A) a hair coloring agent comprising at least a basic dye, a HC dye, a second amino acid, a first cationic surfactant, a thickener, an oil agent, a first pH adjusting agent, a wetting agent and at least one selected from the group consisting of thioglycolic acid, cysteine, 3-mercapto-1,2-propanediol, cysteamine, and derivatives and salts thereof, wherein the pH of the hair coloring agent is pH 3.5 or higher, and (B) a hair cosmetics comprising at least an alkaline agent, a first amino acid, higher alcohols having 12 to 22 carbon atoms, a surfactant, and a thickener. The hair coloring method may further include a step of providing a predetermined time after the application.

The subject of the present application is an agent for the oxidative dyeing of keratinous fibers, in particular human hair, which contains the coupling oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol in combination with the oxidation base 2-(2,5-diaminophenyl)ethanol, wherein the pH of the agent is higher than 8.0.

Compositions that supplement and support nitric oxide availability to skin and methods of use include a first agent that is a precursor of nitric oxide, a second agent that facilitates production of nitric oxide by the first agent, and a third agent that antagonizes (i) nucleotide activation of skeletal muscle ryanodine receptors or (ii) cellular calcium influx. The first, second and third agents are mixed to form a composition suitable for topical application to skin. The composition may include an adenosine, arginine, carnosine, niacinamide, and a magnesium ion source, wherein application of the composition to a skin region increases cutaneous blood flow in the skin region compared to cutaneous blood flow in a similar skin region not treated with the composition, as measured by doppler ultrasound.

Agents for coloring keratinous fibers and methods of dying human hair are provided herein. In an embodiment, an agent is provided for coloring keratinous fibers. The agent is included in a cosmetic carrier and includes at least one non-ionic direct dye and at least about 0.1 wt. %in relation to the entire agentof one or several polyols.

The disclosure provides for nanoliposomal formulations comprising nitroglycerin, methods of making the formulations, and methods of use thereof.
