Method of treating dry, free flowing, dust forming compositions with selected liquids to agglomerate a portion of the particles into groups of particles of sufficient size so that the treated compositions are substantially dust free and retain their free flowing properties, and the compositions produced by such treatment.
摘要:
The specification describes water soluble, cationic products useful as hair colorants or for skin care obtained by oxidative polymerization of a 5,6-dihydroxyindole-2-quaternary amides or esters, as well as compositions containing the same, methods of using the same in compositions to color hair or treat skin and intermediates for producing the products.
摘要:
A process of dyeing hair by preparing and applying to the hair an aqueous reaction medium buffered to a pH of from 7 to 11 with a bicarbonate or a TRIS buffer, a catalytic quantity of a cupric or ferrous salt, a catechol and a persulfate oxidizing agent and removing the composition after the desired color is attained, and compositions and kits for practicing such process. The composition may be formed by simultaneous addition of the catechol and the oxidant to the hair or by addition of the catechol followed by addition of the oxidant.
摘要:
A process of dyeing hair by preparing and applying to the hair an aqueous reaction medium comprising an aminoethanethiol, a dihydroxybenzene and a ferricyanide or persulfate oxidizing agent, the composition optionally containing a color modifier selected from the group consisting of direct dyes, primary intermediates, couplers and mixtures thereof, and also containing a buffer to maintain the pH in the range from 2 to 11 during the oxidation reaction, and removing the aqueous reaction medium from the hair after the desired color is attained, and compositions and kits for practicing such processes.
摘要:
A process of dyeing hair by preparing and applying to the hair an aqueous reaction medium comprising an aminoethanethio substituted dihydroxybenzene and a periodate, iodate, ferricyanide or persulfate oxidizing agent, the composition optionally containing a color modifier selected from the group consisting of direct dyes, primary intermediates, couplers, cysteine, dopa species and mixtures thereof, additionally containing a buffer to maintain the pH in the range from 2 to 11 during the oxidation reaction; and removing the aqueous reaction medium from the hair after formation of the desired color and compositions and kits for practicing such processes. The reaction medium may be formed by simultaneous addition of the dihydroxybenzene and the oxidant to the hair or by addition of the dihydroxybenzene followed by addition of the oxidant.
摘要:
Aqueous dye compositions containing sodium chlorite together with 5,6-dihydroxyindoline or 5,6-dihydroxyindole, its analogs, homologs or derivatives, methods of using the compositions to color hair and packages containing such compositions.
摘要:
A process of dyeing hair by preparing and applying to the hair an aqueous reaction medium comprising dihydroxybenzothiazine and a periodsate, iodate, ferricyanide or persulfate oxidizing agent, the composition optionally containing a color modifier selected from the group consisting of direct dyes, primary intermediates, couplers, cysteine, dopa species and mixtures thereof, additionally containing a buffer to maintain the pH in the range from 2 to 11 during the oxidation reaction; and removing the aqueous reaction medium from the hair after the desired color is attained and compositions and kits for practicing such processes. The reaction medium may be formed by simultaneous addition of the benzothiazine and the oxidant to the hair or by addition of the benzothiazine followed addition of the oxidant.
摘要:
The treatment of proteinaceous or other substrates to render them more manageable and more stable against chemical treatment involves the use of aqueous compositions containing cationic (meth)acrylic copolymers.
摘要:
The present invention concerns the aminophenols (I) as novel couplers ##STR1## wherein R.sub.1 and R.sub.2 may be the same or different and are hydrogen, alkyl and hydroxyalkyl of from 1 to about 6 carbons in the alkyl moiety, or R.sub.1 and R.sub.2 can also form, together with the nitrogen atom to which they are attached, a morpholine, piperidine or pyrrolidine ring, and R.sub.3 and R.sub.4 are hydrogen, alkyl, acyl and hydroxyalkyl having from 1 to about 6 carbons, and oxidative hair dye compositions containing same along with at least one primary dye intermediate in aqueous or hydroalcoholic media.
