Abstract

Use of at least one agent chosen from cyclodextrins and the derivatives thereof as a pearlescent agent, in a composition, for example, a pearlescent cosmetic composition, comprising a physiologically acceptable aqueous medium. Use of at least one agent chosen from cyclodextrins and the derivatives thereof and at least one surfactant in compositions. Pearlescent compositions comprising, a physiologically acceptable aqueous medium, at least one agent chosen from cyclodextrins and the derivatives thereof, at least one surfactant, and at least one conditioning agent; as well as use of at least one agent chosen from cyclodextrins and the derivatives thereof as an agent for suspending an insoluble conditioning agent; wherein the compositions disclosed herein may be used in a form chosen, for example, from rinse-out products, for example, for washing and/or conditioning a keratinous material.

Claims (45)

1. A pearlescent composition comprising,

an aqueous medium,

at least one conditioning agent,

at least one surfactant, and

at least one agent chosen from unsubstituted β-cyclodextrins or methyl β-cyclodextrins,

wherein the at least one surfactant and the at least one agent chosen from unsubstituted β-cyclodextrins or methyl β-cyclodextrins are present in sufficient concentrations to pearl the composition;

wherein the at least one conditioning agent is chosen from poly-α-olefins, fluorinated oils, fluorinated waxes, fluorinated gums, carboxylic acid esters, silicons, cationic polymers, mineral oils, plant oils, animal oils, ceramides, and pseudoceramides; and

wherein the at least one agent chosen from unsubstituted β-cyclodextrins or methyl β-cyclodextrins does not form a complex with the at least one conditioning agent.

2. The composition according to claim 1 , wherein the at least one agent chosen from β-cyclodextrins is present in an amount ranging from 0.2% to 30% by weight, relative to the total weight of the composition.

3. The composition according to claim 2 , wherein the at least one agent chosen from β-cyclodextrins is present in an amount ranging from 1% to 15% by weight, relative to the total weight of the composition.

4. The composition according to claim 1 , wherein the at least one surfactant is present in an amount ranging from 0.2% to 40% by weight, relative to the total weight of the composition.

5. The composition according to claim 4 , wherein the at least one surfactant is present in an amount ranging from 1% to 35% by weight, relative to the total weight of the composition.

6. The composition according to claim 1 , wherein the at least one conditioning agent is present in an amount ranging from 0.001% to 10% by weight, relative to the total weight of the composition.

7. The composition according to claim 6 , wherein the at least one conditioning agent is present in an amount ranging from 0.005% to 5% by weight, relative to the total weight of the composition.

8. The composition according to claim 7 , wherein the at least one conditioning agent is present in an amount ranging from 0.01% to 3% by weight, relative to the total weight of the composition.

9. The composition according to claim 1 , wherein the composition is chosen from gels, milks, creams, lotions, and mousses.

10. The composition according to claim 1 , wherein the composition is a foaming detergent composition.

11. The composition according to claim 10 , wherein the foaming detergent composition is chosen from shampoos, shower gels, and bubble baths.

12. The composition according to claim 1 , wherein the composition is chosen from rinse-out and leave-in conditioner compositions; compositions for permanent-waving, straightening, dyeing and bleaching; compositions to be applied before dyeing, bleaching, permanent-waving and straightening; compositions to be applied after dyeing, bleaching, permanent-waving and straightening; and compositions to be applied between the two steps of a permanent-waving and straightening operation.

13. A pearlescent composition comprising,

an aqueous medium,

at least one conditioning agent, and

at least one insoluble complex in said pearlescent composition, said at least one insoluble complex comprising at least one surfactant and at least one agent chosen from cyclodextrins,

wherein the at least one conditioning agent is chosen from poly-α-olefins, fluorinated oils, fluorinated waxes, fluorinated gums, carboxylic acid esters, silicones, cationic polymers, mineral oils, plant oils, animal oils, ceramides, and pseudoceramides.

14. The composition according to claim 13 , wherein, the at least one agent chosen from cyclodextrins is chosen from α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin.

15. The composition according to claim 14 , wherein the at least one agent chosen from cyclodextrins is chosen from β-cyclodextrin and γ-cyclodextrin.

16. The composition according to claim 14 , wherein the at least one agent chosen from cyclodextrins is chosen from methylcyclodextrins.

17. The composition according to claim 13 , wherein the at least one agent chosen from cyclodextrins is present in an amount ranging from 0.2% to 30% by weight, relative to the total weight of the composition.

18. The composition according to claim 17 , wherein the at least one agent chosen from cyclodextrins is present in an amount ranging from 1% to 15% by weight, relative to the total weight of the composition.

19. The composition according to claim 18 , wherein the at least one surfactant is present in an amount ranging from 0.2% to 40% by weight, relative to the total weight of the composition.

20. The composition according to claim 19 , wherein the at least one surfactant is present in an amount ranging from 1% to 35% by weight, relative to the total weight of the composition.

21. The composition according to claim 13 , wherein the at least one conditioning agent is present in an amount ranging from 0.001% to 10% by weight, relative to the total weight of the composition.

22. The composition according to claim 21 , wherein the at least one conditioning agent is present in an amount ranging from 0.005% to 5% by weight, relative to the total weight of the composition.

23. The composition according to claim 22 , wherein the at least one conditioning agent is present in an amount ranging from 0.01% to 3% by weight, relative to the total weight of the composition.

24. The composition according to claim 13 , wherein the composition is chosen from gels, milks, creams, lotions, and mousses.
