## Abstract

A method for oxidative lightening and/or coloring of keratinic fibers include: a) a coloring and/or lightening agent applied onto the keratinic fibers, which agent is obtained by mixing a composition (A) that contains at least one alkalizing agent with a composition (B) that contains, in a cosmetic carrier, at least one oxidizing agent, b) subsequently, within a time span from about one second to about 24 hours after step a), a post-treatment agent that contains at least one 4-morpholinomethyl-substituted silicone of formula (V), applied onto the keratinic fibers, in particular onto the hair.

## Claims

### Claim 1

A method for oxidative lightening and/or coloring of keratinic fibers, wherein
a) a coloring and/or lightening agent is applied onto the keratinic fibers, which agent is obtained by mixing a composition (A) that contains at least one alkalizing agent with a composition (B) that contains, in a cosmetic carrier, at least one oxidizing agent,
b) subsequently, within a time span from about one second to about 24 hours after step a), a post-treatment agent that contains at least one 4-morpholinomethyl-substituted silicone of formula (V),
in which
A denotes a structural unit (I), (II), or (III) bound via-0
or an oligomeric or polymeric residue bound via —O— containing structural units of formulas (I), (II), or (III), or half of an oxygen atom connecting to a structural unit (III), or denotes —OH,
* denotes a bond to one of the structural units (I), (II), or (III), or denotes a terminal group B (Si-bound) or D (O-bound),
B denotes an —OH, —O—Si(CH3)3, —O—Si(CH3)2OH, —O—Si(CH3)2OCH3 group,
D denotes an —H, —Si(CH3)3, —Si(CH3)2OH, —Si(CH3)2OCH3 group,
a, b, and c denote integers from 0 to 990, with the provision that a+b+c>0,
m, n, and o denote integers from 1 to 990,
is applied onto the keratinic fibers, in particular onto the hair.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the post-treatment agent used in step b) contains at least one 4-morpholinomethyl-substituted silicone of formula (V) in which
m>(n+o)resp.(a+b+c)>(n+o).

### Claim 3 (depends on 1)

The method according to claim 1, wherein the post-treatment agent used in step b) contains, based on its weight, 4-morpholinomethyl-substituted silicone(s) in a total quantity from about 0.001 to about 5 wt %, based on the total weight of the post-treatment agent.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the post-treatment agent used in step b) contains, based on its weight, at least one 4-morpholinomethyl-substituted silicone of formula (V) that respectively comprises at least one of the structural units of formulas (I), (II), and (III), in a total quantity from about 0.001 to about 5 wt %, based on the total weight of the post-treatment agent.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the post-treatment agent used in step b) contains hydroxy-terminated 4-morpholinomethyl-substituted silicone(s) in which the molar ratio of hydroxy to alkoxy is in the range from about 0.2:1 to about 0.4:1.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the weight-average molar mass of the 4-morpholinomethyl-substituted silicone of formula (V) used in step b) is in the range from about 2,000 to about 1,000,000 gmol−1.

### Claim 7 (depends on 1)

The method according to claim 1, wherein the 4-morpholinomethyl-substituted silicone of formula (V) used in step b) is present in the form of an oil-in-water emulsion in which the number-average size of the silicone particles in the emulsion is in the range from about 3 to about 500 nm.

### Claim 8 (depends on 1)

The method according to claim 1, wherein the post-treatment agent applied in method step b) contains at least one further hair-conditioning active substance that is selected from cationic surfactants that are of the quaternary ammonium compound, esterquats, or amidoamines type, from cosmetic oils, from linear C12 to C30 alkanols, from amphoteric polymers and from cationic polymers.

### Claim 9 (depends on 1)

The method according to claim 1, wherein composition (B) contains at least one cosmetic oil in a total quantity from about 10 to about 80 wt %, based on the weight of composition (B).

### Claim 10 (depends on 1)

The method according to claim 1, wherein in method step a) the coloring agent is applied onto the keratinic fibers, which agent is obtained by mixing the composition (A), which contains the at least one alkalizing agent, at least one oxidation dye precursor of the developer type, and at least one oxidation dye precursor of the coupler type, with the composition (B).

### Claim 11 (depends on 1)

The method according to claim 1, wherein the method for oxidative lightening and/or coloring of keratinic fibers is for oxidative lightening and/or coloring of human hair.
