Abstract

Methods for enhancing in-vitro bloom of a rinse-off composition can include combining surfactant, perfume, solvent, and water, to form the composition, wherein the rinse-off cleansing composition has a G′ of at least about 25 Pa and/or is not a ringing gel.

Claims

1. ) A method of enhancing in-vitro bloom of a rinse-off cleansing composition, comprising, combining:

a) from about 35% to about 85%, by weight of the composition, of surfactant;

b) from about 4% to about 30%, by weight of the composition, of a perfume, wherein the weight percent of perfume is from about 12% to about 40%, by weight of the surfactant;

c) from about 6% to about 20%, by weight of the composition, of a hydric solvent and wherein the weight percent of the hydric solvent is from about 16% to about 24%, by weight of the surfactant; and

d) from about 2% to about 57%, by weight of the composition, of water;

to form the cleansing composition;

wherein the rinse-off cleansing composition is not a ringing gel.

2. ) The method of claim 1, wherein the composition has a G′

at 1 Hz of about 25 Pa to about 3000 Pa and wherein the composition has a total GCMS peak area at the 3;

1 dilution point which is at least 1.5 times greater than the GCMS peak area of the composition prior to dilution when measured in accordance with the PHADD method.

3. ) The method of claim 1, wherein the composition comprises from about 35% to about 60%, by weight of the composition, of surfactant.

4. ) The method of claim 1, wherein the surfactant comprises from about 30% to about 40%, by weight of the composition, of a first surfactant.

5. ) The method of claim 4, wherein the first surfactant comprises an anionic surfactant.

6. ) The method of claim 4, wherein the first surfactant comprises a branched anionic surfactant.

7. ) The method of claim 5, wherein the anionic surfactant comprises a sulfate, an alkyl ether sulfate, an alkyl ether sulfate with about 0.5 to about 5 ethoxylate groups, sodium trideceth-2 sulfate, or a combination thereof.

8. ) The method of claim 5, wherein the surfactant comprises sodium trideceth-2 sulfate, sodium trideceth-3 sulfate, sodium laureth-1 sulfate, sodium laureth-2 sulfate, sodium laureth-3 sulfate, or a combination thereof.

9. ) The method of claim 4, wherein the surfactant further comprises from about 2% to about 10%, by weight of the composition, of a cosurfactant.

10. ) The method of claim 9, wherein the cosurfactant comprises a betaine, an alkyl amidopropyl betaine, cocoamidopropyl betaine, or a combination thereof.

11. ) The method of claim 1, wherein the composition comprises from about 8% to about 20%, by weight of the composition, of the perfume.

12. ) The method of claim 1, wherein the composition comprises from about 8% to about 16%, by weight of the composition, of the solvent.

13. ) The method of claim 1, wherein the hydric solvent comprises dipropylene glycol, diethylene glycol, dibutylene glycol, hexylene glycol, butylene glycol, pentylene glycol, heptylene glycol, propylene glycol, a polyethylene glycol having a weight average molecular weight below about 500, or a combination thereof.

14. ) The method of claim 1, wherein the composition comprises from about 30% to about 61%, by weight of the composition, of the combination of water and solvent.

15. ) The method of claim 1, wherein the perfume is from about 20% to about 40%, by weight of the surfactant.

16. ) The method of claim 1, wherein the weight percent of hydric solvent is from about 17% to about 35%, by weight of the surfactant.

17. ) The method of claim 1, wherein the composition is a microemulsion or contains a microemulsion phase.

18. ) The method of claim 1, wherein at least a portion of the composition becomes a microemulsion upon dilution with water of about 3:

1 by weight (water;

composition) to about 10;

1 by weight (water;

composition).

19. ) The method of claim 1, wherein the GCMS peak area is at least about 1.75 times more than the composition prior to dilution.

20. ) A method of enhancing in-vitro bloom of a rinse-off cleansing composition, comprising, combining:

from about 35% to about 45%, by weight of the composition, of a first surfactant comprising sodium trideceth-2 sulfate;

from about 2% to about 10%, by weight of the composition, of a cosurfactant comprising cocamidopropyl betaine;

from about 4% to about 15%, by weight of the composition, of a perfume;

from about 6% to about 20%, by weight of the composition, of dipropylene glycol; and

water;

to form a rinse-off cleansing composition, wherein the rinse-off cleansing composition is not a ringing gel.
