The present disclosure relates to agents for the oxidative coloring of keratinic fibers, which are characterized in hat they contain derivatives of anisole as novel developer molecules.

Agent for oxidative dyeing of hair containing anisole derivatives

The subject matter of the present disclosure are agents for stabilizing keratin fibers, more particularly human hair, containing in a cosmetic carrier: whereinX denotes oxygen (&#x2014;O&#x2014;), sulfur (&#x2014;S&#x2014;) or a grouping &#x2014;NR&#x2014;.

Agent for stabilizing keratin fibers with 5-ring heterocycles

Agents for coloring and/or matting keratinic fibers, in particular human hair, include in a cosmetic carrier at least one specific substituted 1,4-diaminoanthraquinone derivative of formula (I), wherein the residues (R2, R4) mutually independently denote a grouping of formula (II). The cosmetic method of using these agents can be for producing intense blue shades and for matting keratin fibers. 

Means for dyeing and/or matting keratinic fibres containing novel 1,4 diaminoanthraquinone dyes

The present specification provides for an agent for coloring keratinic fibers. The agent includes, a cosmetic carrier, a compound of formula (I), R1 and R2 independently of one another denote hydrogen, a C-Calkyl group, a C-Calkenyl group, a hydroxyl group, a halogen, a C-Calkoxy group, an amino group, a nitro group, an acetyl amino group, or a sulfonamide group; or when in ortho-position to one another, form a 5- or 6-membered, saturated or unsaturated ring, which optionally include further heteroatoms.

Anionic azo dyestuffs for coloring keratin-containing fibers

The invention relates to agents for coloring keratinic fibers, in particular human hair, including in a cosmetic carrier at least one compound of the formula (I). The structures the of the general formula (I) have a heterocycle A which bears a quaternary nitrogen atom and thus a positive charge. The invention furthermore relates to the use of these novel azo dyes in agents for coloring hair and to the dyes themselves.

Zwitterionic azo dyestuffs for coloring keratin-including fibres

An agent for the oxidative dyeing of keratinous fibers is provided. The agent contains, as a developer-type oxidation dye precursor, a compound of Formula (I) that carries at least one cationic charge in Y.

Oxidation dye precursors

The invention provides an agent for lightening keratinic fibers, the agent containing in a cosmetic carrier (i) at least one acyl pyridinium derivative of formula (I), (ii) at least one alkalizing agent selected from triethanolamine, 2-amino-2-methylpropan-1-ol, 2-amino-2-methylpropane-1,3-diol, lysine, ornithine and/or an alkalizing agent mixture comprising at least one basic amino acid and at least one alkanolamine, and (iii) at least hydrogen peroxide as an oxidizing agent.

Brightening agent comprising acylpyridinium compounds and defined alkalizing agents

The invention provides an agent for lightening keratinic fibers, the agent containing in a cosmetic carrier (i) at least one acyl pyridinium derivative of formula (I), (ii) at least one cationic polysaccharide, and (iii) at least hydrogen peroxide as an oxidizing agent.

Lightening agent comprising acyl pyridinium compounds and cationic polysaccharides

Cosmetic hair post-treatment agent for improving washing fastness of coloring processes produced on hair and for color fixing, the post-treatment agent containing, in a cosmetic carrier, at least one acetylpyridinium derivative of formula (I) wherein R1 is a Cto Calkyl group, a Cto Calkenyl group, a Cto Chydroxyalkyl group, a Cto Calkoxy-Cto Calkyl group, a carboxy-Cto Calkyl group, an aryl-Cto Calkyl group, a heteroaryl-Cto Calkyl group, an aryl group, or a heteroaryl group, and Xis a physiologically acceptable anion.

After treatment for color fixation

Agent for lightening keratin fibers, particularly human hair. The agent for lightening keratin fibers contains at least one cationic phthalimide of formula (I) in addition to an oxidant in a cosmetic carrier. 

Phthalimides as bleach activators

Agent for lightening keratinic fibers, particularly human hair, wherein the agent contains, in a cosmetic carrier, at least one oxidizing agent chosen from hydrogen peroxide and/or a solid addition product thereof with organic or inorganic compounds, and at least one sulfonimine of formula (I)&#x2014; 

Sulfonimines as bleaching activators

Method for lightening keratinous fibers, wherein a cosmetic carrier comprises (i) at least one oxidation agent, (ii) at least one acylpyridinium derivative of formula (I) and (iii) at least one amino acid comprising hydroxyl groups and/or the physiologically compatible salts thereof and/or the alkyl esters thereof.

Lightening agent having cationic acylpyridinium derivatives and certain amino acids

Agent for lightening keratinous fibers comprising in a cosmetic carrier (i) at least one oxidation agent, (ii) at least one acylpyridinium derivative of Formula (I) and (iii) at least one ammonium compound comprising hydroxyl groups of Formula (II).

Lightening agent having cationic acylpyridinium derivatives and certain ammonium compounds

Agent for lightening keratin fibers containing in a cosmetic carrier (1) at least one cationic 2-acylpyridinium derivative of formula (I), wherein R is a C-Calkyl group, a C-Calkenyl group, a C-Chydroxyalkyl group, a C-Calkoxy C-Calkyl group, a carboxy C-Calkyl group, an aryl C-Calkyl group, a heteroaryl C-Calkyl group, a mono- or di-(C-Calkyl)amino C-Calkyl group, a 3-oxobutyl group, a 2-oxopropyl group, an aryl group or a heteroaryl group, R' is a C-Calkyl group, a C-Chydroxyalkyl group or a C-Calkoxy C-Calkyl group, and Xis a physiologically acceptable anion, (2) at least one alkyl ether sulfate, and (3) an oxidizing agent, especially hydrogen peroxide.

Bleaching agent comprising 2-acylpyridinium derivatives

Agent for dyeing keratin fibers while simultaneously bleaching the keratin fibers. The agent contains, in a cosmetic carrier, at least one oxidation dye precursor and at least one cationic acylpyridinium derivative.

Cationic acylpyridinium derivatives for use as bleach activators
