Abstract

The present invention relates to an agent for oxidatively coloring or blonding hair that is gentle on the hair, and to a gentle method for oxidatively coloring or blonding hair, in which keratin fibers are protected from oxidative influences.

First claim

What is claimed is:

1. An oxidative coloring or blonding agent for keratin fibers, comprising:
a) 0.9 to 3 wt % of at least one polymer A, which includes at least ten constitutional units of formula (I),

where
X denotes nitrogen or oxygen, and
R 1 and R 2 , each independently of one another, denote hydrogen or a C2 to C10 acyl group, or R 1 and R 2 together form a five-membered or six-membered, saturated or unsaturated ring, which optionally includes further heteroatoms, and/or optionally is substituted with at least one C1 to C6 alkyl group and/or with at least one functional group, and
p=0 when X denotes oxygen, and p=1 when X denotes nitrogen,

b) furthermore comprising at least two permanently cationic polymer selected from mixtures of at least one quaternized polysaccharide and at least one polymer comprising acrylamidopropyltrimethylammonium units,
c) 0.5 wt % to 5 wt % of at least one amino acid,
d) furthermore at least one alkalizing agent, selected from ammonium hydroxide, monoethanolamine and sodium silicates, and mixtures thereof,
e) optionally at least one oxidation dye precursor and/or at least one direct dye,
f) water, and
g) at least one peroxide compound
h) at least one compound of the general formula (III) is present in the coloring or blonding agent,

wherein
R1 denotes a hydrogen atom or a structural element of formula (IV)

wherein
x denotes an integer from 1 to 100,
the group R2 in each of the structural elements of formula (IV) can each be selected independently of a hydrogen atom, a methyl group, an isopropyl group, a 2-methylpropyl group, a 1-methylpropyl group, a benzyl group, a 4-hydroxybenzyl group, a hydroxymethyl group, a 1-hydroxyethyl group, a 4-aminobutyl group, a 3-carbamimidamidopropyl group, a 2-carboxyethyl group, a carboxymethyl group, a 2-carbamoylethyl group, a carbamoylmethyl group, a sulfanylmethyl group, a 2-(methylsulfanyl)ethyl group, a 1H-imidazole-4-ylmethyl group, a 1H-indole-3-ylmethyl group or a (sulfosulfanyl)methyl group, M1 denotes the group —OM2 or a structural element of formula (V),

wherein
y denotes an integer from 1 to 100,
the group R3 in each of the structural elements of formula (V) can each be selected independently of a hydrogen atom, a methyl group, an isopropyl group, a 2-methylpropyl group, a 1-methylpropyl group, a benzyl group, a 4-hydroxybenzyl group, a hydroxymethyl group, a 1-hydroxyethyl group, a 4-aminobutyl group, a 3-carbamimidamidopropyl group, a 2-carboxyethyl group, a carboxymethyl group, a 2-carbamoylethyl group, a carbamoylmethyl group, a sulfanylmethyl group, a 2-(methylsulfanyl)ethyl group, a 1H-imidazole-4-ylmethyl group, a 1H-indole-3-ylmethyl group or a (sulfosulfanyl)methyl group,

M2 denotes a hydrogen atom, an equivalent of a monovalent or polyvalent cation, or an ammonium ion (NH 4 ) + .

2. The coloring or blonding agent according to claim 1 , wherein the at least one polymer A including at least ten constitutional units of formula (I) is selected from polymers that comprise 98 to 100 mol % of constitutional units of formula (Ia)

and have a degree of polymerization in the range of 40 to 1000, wherein the polymer A does not include any permanently ionic constitutional units.

3. The coloring or blonding agent according to claim 1 , wherein the at least one polymer including at least ten constitutional units of formula (I) is present in a total amount of 1.5 to 2.3 wt. %, based on the weight of the coloring or blonding agent.

4. The coloring or blonding agent according to claim 1 , wherein the at least one amino acid is selected from the group consisting of serine, arginine, histidine and lysine, and mixtures thereof.

5. The coloring or blonding agent according to claim 1 , wherein the at least one amino acid is selected from the basic amino acids arginine, histidine and lysine.

6. The coloring or blonding agent according to claim 1 , wherein the at least one amino acid includes serine and at least one of the basic amino acids arginine, histidine or lysine are present in a molar ratio of serine to basic amino acids overall in the range of 1:1 to 50:1.

7. The coloring or blonding agent according to claim 1 , wherein the peroxide compound is hydrogen peroxide.

8. A method for oxidatively coloring and/or lighting keratin fibers, comprising applying a coloring or blonding agent according to claim 1 to keratin fibers, and rinsing off the coloring or blonding agent from the keratin fibers after an exposure time of 1 to 60 minutes.

9. A method for oxidatively coloring and/or lightening keratin fibers, comprising:
I. providing a composition (A), comprising
a) at least one polymer, which includes at least ten constitutional units of formula (I),

where
X denotes nitrogen or oxygen, and
R 1 and R 2 , each independently of one another, denote hydrogen or a C2 to C10 acyl group, or R 1 and R 2 together form a five-membered or six-membered, saturated or unsaturated ring, which optionally includes further heteroatoms, and/or optionally is substituted with at least one C1 to C6 alkyl group and/or with at least one functional group, and
p=0 when X denotes oxygen, and p=1 when X denotes nitrogen,

b) furthermore comprising at least two permanently cationic polymer selected from mixtures of at least one quaternized polysaccharide and at least one polymer comprising acrylamidopropyltrimethylammonium units,
c) furthermore at least one amino acid,
d) water, and
e) at least one compound of the general formula (III) is present in the coloring or blonding agent,
