Abstract

Abstract The present invention provides the following hair-treatment composition, bleaching composition and hair color tone modifier composition: a hair-treatment composition containing: (1) a ferrous salt, and (2) a nonreducing organic chelate-forming compound capable of forming a chelate compound together with a ferrous ion, and having a pH value of from 3 to 6, wherein the stability constant (K 1 ) between said ferrous ion and said nonreducing organic chelate-forming compound is lower than 3 and the ferrous salt, which is the chelate compound of said ferrous ion with said nonreducing organic chelate-forming compound, is highly soluble in water; a hair-treatment composition containing: (1) a ferrous salt, and (2) a nonreducing organic chelate-forming compound represented by the following general formula (I): ##STR1## wherein R represents a straight-chain or branched hydrocarbon group having 1 to 10 carbon atoms or an oxane ring, and m is an integer of from 1 to 6, capable of forming a chelate compound with a ferrous ion and having a pH value of from 3 to 6; a bleaching composition consisting of either one of the above-mentioned hair-treatment compositions as the primary agent together with an aqueous composition containing 0.01 to 3% by weight of hydrogen peroxide and having a pH value of from 3 to 6 as the secondary agent; and a hair color tone modifier composition obtained by adding a direct dye to the primary and/or secondary agents of the above-mentioned bleaching composition.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 226 words
A hair color tone modifier composition comprising: (1) a first hair treatment composition comprised of: (a) a ferrous salt, and (b) a non-reducing organic chelate-forming compound having the formula (II): ##STR5## wherein R and R may be the same of different and wherein R represents a hydrogen atom, a straight-chain or branched alkyl group having one to five carbon atoms or an alkenyl group having one to five carbon atoms, and wherein R represents a straight-chain or branched alkyl group having one to five carbon atoms or an alkenyl group having one to five carbon atoms, n is from 0 to 2 and m is from 0 to 6, and wherein when m is 1 to 6, said hydroxyl group may be bound at any position on said R; and wherein said non-reducing organic chelate-forming compound (II) is capable of forming a chelate compound with a ferrous ion having a pH of from 3 to 6, wherein the stability constant (K 1 ) between said ferrous ion and said non-reducing organic chelate-forming compound is lower than 3 and wherein said ferrous salt, which is the chelate compound is highly soluble in water; and (2) a second aqueous composition containing 0.01 to 3% by weight of hydrogen peroxide having a pH from 3 to 6, wherein a direct dye is added to either composition (1) or (2).
Claim 2
Dependent Claim 226 words
A hair color tone modifier composition comprising: (1) a first hair treatment composition comprised of: (a) a ferrous salt, and (b) a non-reducing organic chelate-forming compound having the formula (II): ##STR5## wherein R and R may be the same of different and wherein R represents a hydrogen atom, a straight-chain or branched alkyl group having one to five carbon atoms or an alkenyl group having one to five carbon atoms, and wherein R represents a straight-chain or branched alkyl group having one to five carbon atoms or an alkenyl group having one to five carbon atoms, n is from 0 to 2 and m is from 0 to 6, and wherein when m is 1 to 6, said hydroxyl group may be bound at any position on said R; and wherein said non-reducing organic chelate-forming compound (II) is capable of forming a chelate compound with a ferrous ion having a pH of from 3 to 6, wherein the stability constant (K 1 ) between said ferrous ion and said non-reducing organic chelate-forming compound is lower than 3 and wherein said ferrous salt, which is the chelate compound is highly soluble in water; and (2) a second aqueous composition containing 0.01 to 3% by weight of hydrogen peroxide having a pH from 3 to 6, wherein a direct dye is added to either composition (1) or (2).
Claim 3
Dependent Claim 58 words
A hair color tone modifier composition comprising: (1) a first hair treatment composition as claimed in claim 6; and (2) a second aqueous composition containing 0.01 to 3% by weight of hydrogen peroxide having a pH of from 3 to 6, and wherein 0.0001 to 5.0% of a direct dye is added to either composition (1) or (2).
Claim 4
Dependent Claim 56 words
A method for bleaching hair which comprises the sequential steps of: (a) applying to the hair a hair treatment composition as claimed in claim 5; and (b) applying to the hair at pH 3 to 6 and aqueous composition containing 0.01 to 3% by weight of hydrogen peroxide having a pH of from 3 to 6.
Claim 5
Dependent Claim 60 words
A method for bleaching hair which comprises the sequential steps of: (a) applying to the hair a hair treatment composition as claimed in claim 6 as the primary agent; and (b) applying to the hair at pH 3 to 6 an aqueous composition containing 0.01 to 3% by weight of hydrogen peroxide having a pH of from 3 to 6.
