## Abstract

Cosmetic agents for simultaneously lightening and temporarily shaping keratin fibers include a specific thickener and also at least one oxidant and have a viscosity of from 31,000 to 90,000 mPas. Despite the high viscosity, the agents can be easily removed from the packaging and moreover can be homogeneously applied to the keratin fibers without said agents dripping after application. The agents result in a homogeneous lightening and a good hairstyle hold. A method for lightening and temporarily shaping keratin fibers uses such cosmetic agents.

## Claims

### Claim 1

A cosmetic agent for lightening and temporarily shaping keratin fibers, containing, in a cosmetically acceptable carrier,
a) at least one thickener, selected from xanthan gum and/or crosslinked anionic copolymers, including at least one structural unit of formula (I) and at least one structural unit of formula (II)
in which
R1 and R4 each independently of one another represent hydrogen or a C1-4 alkyl group,
R2 and R3 each independently of one another represent a C1-4 alkyl group,
A represents O, NH, or S,
b represents integers from 1 to 5,
X+ represents a physiologically acceptable cation, and
b) at least one oxidant,
wherein the cosmetic agent has a viscosity of from 31,000 to 90,000 mPas (Brookfield RV, spindle T96, 4 rpm).

### Claim 2 (depends on 1)

The cosmetic agent according to claim 1, wherein the residue R1 in the structural unit of formula (I) and the residue R4 in the structural unit of formula (II) each represent hydrogen.

### Claim 3 (depends on 1)

The cosmetic agent according to claim 1, wherein in the structural unit of formula (I), the residues R2 and R3 each independently of one another represent a C1 alkyl group.

### Claim 4 (depends on 1)

The cosmetic agent according to claim 1, wherein the crosslinked anionic copolymer contains at least one structural unit of formula (Ia) and at least one structural unit of formula (IIa)

### Claim 5 (depends on 1)

The cosmetic agent according to claim 1, wherein the thickener is contained in a total amount of from 0.20 to 7.0 wt % in relation to the total weight of the cosmetic agent.

### Claim 6 (depends on 1)

The cosmetic agent according to claim 1, wherein the oxidant is selected from the group consisting of persulfates, chlorites, hydrogen peroxide, and addition products of hydrogen peroxide with urea, melamine, and sodium borate.

### Claim 7 (depends on 1)

The cosmetic agent according to claim 1, wherein the oxidant, in particular hydrogen peroxide, is contained in a total amount of from 1.0 to 12 wt % in relation to the total weight of the cosmetic composition.

### Claim 8 (depends on 1)

The cosmetic agent according to claim 1, wherein the cosmetic agent has a viscosity of from 31,000 to 85,000 mPas measured with a Brookfield RV, spindle T96, 4 rpm,

### Claim 9 (depends on 1)

A method for lightening and temporarily shaping keratin fibers, wherein a cosmetic agent according to claim 1 is applied to the keratin fibers and the latter are then shaped as desired.
