The invention relates to hair colouring compositions in gel or emulsion-gel form containing no ethoxylated additives, ethanolamine or polyethylene glycols.

Hair colouring compositions in gel or emulsion-gel form

A hair-colouring composition comprising an estolide ester derived from ricinoleic acid and direct dyes.

Hair coloring compositions

The present invention relates to hair colouring compositions free of resorcinol, 2-methyl resorcinol, 4-chloro resorcinol and resorcinol derivatives and free of methoxymethyl-p-phenylenediamine, said compositions comprising at least three dyes selected from at least one primary dye selected from p-toluenediamine sulphate, p-aminophenol, N-methyl-p-aminophenol sulphate and 1-hydroxyethyl-4,5-diamino pyrazole sulphate, and at least two secondary dyes selected from hydroxyethyl 3,4-methylenedioxyaniline HCl, 2-amino-3-hydroxypyridine and 2-methyl-5-hydroxyethylaminophenol, or at least two primary dyes selected from p-toluenediamine sulphate, p-aminophenol, N-methyl-p-aminophenol sulphate and 1-hydroxyethyl-4,5-diamino pyrazole sulphate, and at least one secondary dye selected from hydroxyethyl 3,4-methylenedioxyaniline HCl, 2-amino-3-hydroxypyridine and 2-methyl-5-hydroxyethylaminophenol.

Resorcinol-free hair colouring compositions

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.

Hair colouring compositions

Disclosed are m-aminophenol-free hair-colouring compositions comprising a mixture of dyes consisting of methoxymethyl-p-phenylenediamine, hydroxyethyl-3,4-methylenedioxyaniline and 5-amino-6-chloro-o-cresol, an alkalising agent, and optionally other oxidative dyes, provided that they are not p-phenylenediamine or p-toluenediamine The compositions according to the invention provide stable colours that do not change with time.

M-aminophenol-free hair-colouring compositions

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.

Keratin fiber dyeing composition

The present invention refers to a hair dye comprising a) an alkalinising agent consisting of at least one amino acid having a pKa of greater than 10.00 and at least one ester of a fatty acid and glycerol polyethoxylate; and b) at least one oxidation colourant. In particular, the composition of the invention does not comprise any further alkalinizing agent. Kits and methods for colouring hair based on this composition also fall within the scope of this invention.

Composition for colouring keratin fibres

The invention concerns ready to use compositions for the reshaping and direct coloring of hair comprising glyoxylic acid, a glyoxyloyl amino acid or a mixture thereof and a direct dye, and a method for reshaping and coloring of hair by means of said compositions.

Compositions and methods for simultaneous reshaping and direct coloring of hair

The present invention describes a composition for coloring hair, comprising at least one dye having the formula (I) and at least one dye having the formula (II): where the groups are defined in the description. The composition provides hair colorings stable and brilliant at various pH values and also resistant to washing.

Composition for colouring hair

Disclosed are compositions for dyeing keratin fibers comprising at least one direct dye and/or an oxidative dye and optionally an activator, and also comprising a compound formed by esterification of phosphoric acid with isooctanol (2-ethylhexanol) and ethoxylated tridecylic alcohol.

Keratin fibre dyeing composition

The present invention relates to ready-to-use gel compositions for coloring hair in the form of an aqueous solution comprising:
