The subject of the present invention is a composition for dyeing human keratin fibres such as the hair, comprising: (a) at least one colouring agent chosen from oxidation dye precursors, direct dyes and mixtures thereof; (b) at least one amphoteric or zwitterionic surfactant; (c) at least one non-ionic surfactant; (d)at least one anionic surfactant (e) one or more fatty substances at a total content of at least 10% by weight relative to the weight of the composition; (f) at least one cationic polymer; (g) at least one oxidizing agent other than atmospheric oxygen. The present invention also relates to a process for dyeing human keratin fibres, in which this composition is applied to said fibres, and also to a suitable multicompartment device.

The invention relates to a cosmetic composition comprising: one or more linear α-olefin sulfonates, one or more anionic surfactants present in the composition in an amount ranging from 1% to 20% by weight; and one or more additional surfactants chosen from amphoteric surfactants and nonionic surfactants,
the weight ratio of the amount of linear α-olefin sulfonates to the amount of anionic surfactants being greater than or equal to 1.

The invention also relates to a cosmetic treatment process using said composition, especially a process for caring for and/or cleansing keratin materials.

The purpose of the present invention to solve the problem is to provide a hair cleansing composition that can provide the feeling in use and a stable appearance. The hair cleansing composition comprises: 14 to 35% by mass of a sugar and/or a sugar alcohol; 5 to 20% by mass of an anionic surfactant, 50% or more of the anionic surfactant being an N-acyl-N-methyl taurate and/or an N-acyl-glutamate; 5 to 20% by mass of an alkamidopropyl betaine and/or an alkyl betaine; 0.05 to 1% by mass of a cationic polymer; and 0.01 to 1.5% by mass of an inorganic salt; wherein the hair cleansing composition has a viscosity of 800 to 20000 mPa.Math.s.

Disclosed is a composition comprising, in an aqueous phase: a) at least one ether of formula (I): R—O—R′ in which R and R′, which may be identical or different, denotes a linear or branched C.sub.6-C.sub.25 alkyl or alkenyl radical, R and R′ being chosen such that the ether is liquid at a temperature of less than or equal to 30° C.; b) at least one surfactant chosen from anionic surfactant, amphoteric or zwitterionic surfactant, or a mixture thereof; c) at least one cationic alkyldiallylamine or dialkyldiallylammonium cyclopolymer; and d) soybean oil.

Provided is a composition comprising, in an aqueous phase at least one anionic surfactant, at least one amphoteric and/or zwitterionic surfactant, at least one alkyl(poly)glycoside nonionic surfactant, at least on polymer chosen from cationic polymers of cationic cellulose, cationic alkyldiallylamine or dialkyldiallylammonium cyclopolymer, amphoteric polymers which comprising one or more units derived from a monomer of (meth)acrylate or (meth)acrylamide type, a monomer of (meth)acrylamidoalkyltrialkylammonium type, or a monomer of (meth)acrylic type, or a mixture thereof, and at least on fatty acid ester of glycerol and/or of polyglycerol.

The present invention relates to a cosmetic composition, comprising: (a) at least one compound having a specific chemical structure with two or more fatty amide groups; (b) at least one monosacharide. The cosmetic composition according to the present invention can have superior skin hydration effects because the hydration effect of each of the components (a) and (b) is synergistically enhanced by the combination of the components (a) and (b).

The disclosure provides a liquid hand soap or body wash, comprising (i) a surfactant system comprising C.sub.8-18 alkyl-ether sulfate, cocamidopropyl betaine (CAPB), and N-(2 hydroxyethyl) fatty acid amide; (ii) a polyethylene oxide-polypropylene oxide block copolymer; and (iii) one or more polyalkoxylated mono- or di-fatty acid esters or amides, the composition allowing reduced surfactant levels, while still having good rheological properties.

Disclosed is a hair colouring composition containing amino acids with at least a pKa greater than 10, oxidative dyes, and acetylaspartic acid or salts thereof. The compositions according to the invention do not contain ammonia or ethanolamine, do not damage the hair, guarantee shine and combability, and also cover white hair and withstand blue light.

The present disclosure relates to methods for treating hair, which are particularly useful for repairing, strengthening, and protecting hair from damage. The methods include applying to the hair each of the following components, together, separately, or in any combination thereof, in one or more hair-treatment compositions: (a) at least one amino acid or amino sulfonic acid, and/or a salt thereof, which is present in at least one of the one or more hair-treatment compositions in an amount of at least 0.5 wt. %; (b) at least one non-polymeric mono, di, or tricarboxylic acid, and/or a salt thereof, which is present in at least one of the one or more hair-treatment compositions in an amount of at least 0.5 wt. %; and (c) at least one non-taurate surfactant, which is present in at least one of the one or more hair-treatment compositions.

Hair treated with the methods exhibit desirable cosmetic properties such as smoothness, gloss, improved combability, and improved strength and elasticity.

The present disclosure relates to antimicrobial skin disinfectant compositions such as hand disinfectant soaps, comprising one or more quaternary ammonium compounds, one or more surfactants and an aromatic alcohol, achieving anti-bacterial and fungicidal or yeasticidal efficacy in short contact times.
