Process for preparing dye compositions containing 5,6-dihydroxyindole

A process for preparing dye compositions which comprises hydrolyzing an O-protected 5,6-dihydroxyindole with an alkaline material under substantially anaerobic condition and the products made by such process.

Dye compositions containing 5,6-dihydroxy indoles and a foam generator

Process for dyeing human hair by the sequential treatment of the hair with a metal ion and particularly transition metal ion containing composition and with a dye composition containing 5,6-dihydroxyindole-2-carboxylic acid.

Process for dyeing hair by the sequential treatment of hair with metal

A hair dyeing process which comprises of steps of contacting the hair to be dyed with an aqueous solution of a metal salt that promotes melanogenses in air. Before or after the aforementioned step contacting the hair with a solution of 5,6-dihydroxyindole, rinsing the hair between the two contacting steps, maintaining the contact with the second-used solution until a desired darker color is obtained, rinsing or shampooing the hair, then contacting the hair with a solution of hydrogen peroxide until the desired color shade is obtained, and then again rinsing the hair.

Hair dyeing process and compositons package

Hair on a live head is treated with metal ion in a pretreatment step then subjected to an oxidative or autooxidative dyeing step in which scalp staining occurs. Between the pretreatment step and the dyeing step the scalp of the live head is subjected to vigorous massage, rubbing, combing or brushing for a time sufficient to reduce scalp staining, or sufficient time is permitted to elapse between the pretreatment step of the dyeing step to reduce scalp staining, or a combination of these two procedures is employed.

The invention provides compositions and methods for oxidative hair dyeing utilizing a chlorite salt as the oxidizing agent.

Chlorites as oxidants in hair coloring

A process and composition for dyeing hair involving the precipitation of an anionic polymeric dye by means of a cationic polymer preferably in the presence of a surfactant and particularly an amphoteric surfactant.

Process and composition for dyeing hair utilizing an anionic

A process for coloring hair in which a functional metal ion and aminoalkyl or aminohydroxyalkyl catechols are used in combination or applied sequentially to dye the hair rapidly.

Coloring hair with aminoalkyl-or aminohydroxyalkyl-catechols

Compounds of formula: ##STR1## and oxidation hair dye compositions containing the same; also includes a process for dyeing hair with such compositions; Ar being an aryl radical.

2,4-bis-aryloxy-m-phenylenediamines and their use as couplers in

A substituted m-aminophenol coupler useful in hair dyeing having the formula ##STR1## and acid addition salts thereof wherein x and y are selected from the group consisting of halogen and the groups OR of which R is the same or different alkyl, aminoalkyl or hydroxyalkyl groups, at least one of x or y being a group OR and a process for preparing these compounds.

Hair dye coupler and process for making

2-Equivalent oxidative hair dye coupler compounds of the formula (I) ##STR1## wherein X is halogen or OR', wherein R and R' may be the same or different and represent alkyl, mono- or poly-hydroxyalkyl, alkoxyalkyl, alkylphenyl, aminoalkyl, mono- and di-alkylaminoalkyl, phenyl or phenylalkyl except that R and R' are not both methyl, and the acid addition salts thereof are used in oxidative hair dye compositions with conventional para bases. The amount of oxidizing agent can be reduced relative to similar compositions containing 4-equivalent meta coupler compounds. Some of the compounds of formula (I) in which X is OR' are novel compounds as is the elimination of HOR' during the oxidative coupling reaction.
