Abstract

The present disclosure concerns an agent for colouring keratinous fibres, in particular human hair, containing, in a cosmetic support,

• (a) at least one direct dye,
• (b) at least one amphoteric surfactant, in particular at least one alkylbetaine, and
• (c) at least one alkylpolyglycoside, in particular at least one alkylpolyglucoside, exemplified in that the content of amphoteric surfactant (b) in the agent—with respect to the total weight of the agent—is greater than the content of non-ionic surfactant (c). The present disclosure also concerns the use of the agent to colour keratinous fibres, as well as to a method in which the agent is applied to the keratinous fibres in order to colour them.

Claims

1. An agent for colouring keratinous fibres comprising, in a cosmetic support,

(a) at least one direct dye,

(b) at least one amphoteric surfactant, and

(c) at least one alkylpolyglycoside wherein the total content of amphoteric surfactant (b) in the agent—

with respect to the weight of the agent—

is greater than the total content of alkylpolyglycoside (c).

2. The agent as claimed in claim 1, wherein the total content of amphoteric surfactant (b) and alkylpolyglycoside (c) together amounts to from about 1.0 to about 25.0% by weight.

3. The agent as claimed in claim 1, comprising the at least one amphoteric surfactant (b) in a total quantity of from about 0.5 to about 20.0% by weight.

4. The agent as claimed in claim 1, wherein it comprises at least one alkylpolyglycoside (c) in a total quantity of from about 0.5 to about 14.5% by weight.

5. The agent as claimed in claim 1, wherein the amphoteric surfactant (b) is an alkylbetaine.

6. The agent as claimed in claim 1, wherein the alkylpolyglycoside (c) is an alkylpolyglucoside.

7. The agent as claimed in claim 1, wherein the amphoteric surfactant (b) is an alkylamidoalkylbetaine, and the alkylpolyglucoside (c) is an alkylpolyglucoside.

8. The agent as claimed in claim 1, wherein the agent comprises sodium chloride in a quantity of <

0.2% by weight, with respect to the total weight of the agent.

9. The agent as claimed in claim 1, wherein the agent comprises from about 0 to ≤

0.2% by weight of surfactants which comprise a sulphate group.

10. The agent as claimed in claim 1, wherein the agent comprises ≤

0.2% by weight, with respect to the total weight of the agent, of anionic surfactants.

11. The agent as claimed in claim 1, comprising the at least one direct dye (a) in a total quantity of from about 0.001 to about 7% by weight with respect to the weight of the agent.

12. The agent as claimed in claim 1, wherein the agent further comprises at least one associative thickening agent, in a quantity—

with respect to the total weight of the agent—

of from about 0.1 to about 5% by weight.

13. The agent as claimed in claim 1, wherein the agent further comprises at least one film-forming agent, in a quantity—

with respect to the total weight of the agent—

of from about 0.1 to about 5% by weight.

14. The agent as claimed in claim 1, wherein the agent comprises at least one non-ionic associative thickening agent, and at least one cationic polymer, in combination with each other.

15. A method for colouring keratinous fibres in which an agent as claimed in claim 1 is applied to the keratinous fibres.

16. The agent as claimed in claim 1, comprising

the at least one direct dye (a) in a total quantity of from about 0.6 to about 1% by weight, with respect to the weight of the agent;

the at least one amphoteric surfactant (b) in a total quantity of from about 3.0 to 7.0% by weight, with respect to the weight of the agent;

the at least one alkylpolyglycoside (c) in a total quantity of from about 1.5 to about 4.0% by weight, with respect to the weight of the agent.

17. The agent as claimed in claim 1, wherein the amphoteric surfactant (b) is an alkylamidoalkylbetaine and wherein the alkylpolyglycoside (c) is an alkylpolyglucoside with an alkyl residue having from about 10 to about 20 carbon atoms.

18. The agent as claimed in claim 1, wherein the amphoteric surfactant (b) is cocamidopropylbetaine ((C₁₁H₂₃)C(O)NH(C₃H₆)N(NH₂)₂CH₂C(O)O) and the alkylpolyglucoside (c) is laurylglycoside.

19. The agent as claimed in claim 1, wherein the agent comprises:

sodium chloride in a quantity of about 0% by weight, with respect to the total weight of the agent;

0 to ≤

0.1% by weight, with respect to the weight of the agent, of surfactants which comprise a sulphate group;

at least one associative thickening agent, in a quantity—

with respect to the total weight of the agent—

of from about 0.1 to about 5% by weight; and

at least one film-forming agent, in a quantity—

with respect to the total weight of the agent—

of from about 0.1 to about 5% by weight.

20. An agent for colouring keratinous fibres comprising, in a cosmetic support,

(a) at least one direct dye in a total quantity of from about 0.001 to about 7% by weight,

(b) at least one amphoteric surfactant in a total quantity of from about 0.5 to about 20.0% by weight, with respect to the weight of the agent, and

(c) at least one alkylpolyglycoside in a total quantity of from about 0.5 to about 14.5% by weight, with respect to the weight of the agent

wherein the total content of amphoteric surfactant (b) in the agent—

with respect to the weight of the agent—

is greater than the total content of alkylpolyglycoside (c),

wherein the total content of amphoteric surfactant (b) and alkylpolyglycoside (c) together amounts to from about 1.5 to about 20.0% by weight, with respect to the total weight of the agent.
