Abstract

The present invention relates to concentrated personal cleansing compositions having desirable lathering and dissolution properties.

Claims

1. A concentrated personal cleansing composition comprising:

a. greater than about 23 wt % surfactant, wherein said surfactant is in an isotropic phase in said composition; and

b. greater than about 0.05 wt % conditioning agent

wherein the composition that is substantially free of organic solvent and hydrotrope, has a lather index greater than about 0.75 and a dissolution value of less than about 200 sec.

2. The composition of claim 1, wherein said lather index is from about 0.75 to about 1.5, and said dissolution value is from about 10 sec to about 200 sec.

3. The composition of claim 2, wherein said dissolution value is from about 100 sec to about 200 sec.

4. The composition of claim 1, where said surfactant comprises an effective amount of Isotropic Enabler.

5. The composition of claim 4, wherein said Isotropic Enabler is selected from the group consisting of:

branched and non-branched versions of decyl and undecyl alkyl sulfates which are either ethoxylated or non-ethoxylated;

decyl alcohol modified lauryl sulfate;

paraffin sulfonates with chain lengths ranging from C₁₃ to C₁₇;

mixtures of linear and branched-chain alcohol sulfates with carbon chain lengths C₁₂ to C₁₇ which are ethoxylated or non-ethoxylated;

sodium salts of branched, methyl-2-hydroxy-decyl ether sulfates, hydroxyethyl-2-dodecyl ether sulfates, hydroxyethyl-2-decyl ether sulfates;

monoethoxylated lauryl alkyl sulfates; and

mixtures thereof.

6. The composition of claim 1, wherein said conditioning agent is selected from the group consisting of silicones, oils, cationic polymers, and mixtures thereof.

7. The composition of claim 1, wherein said composition has a bubble size of less than about 0.025 mm².

8. The composition of claim 7, wherein said composition has a bubble size of from about 0.005 mm² to about 0.025 mm².

9. The composition of claim 8, wherein said composition has a bubble size of from about 0.005 mm² to 0.02 mm².

10. The composition of claim 1, wherein said composition has an instant shear of:

a. A peak value from about 0.2 to 8 Pa-s;

b. A value of less than about 0.8 Pa-s at 1.2 sec;

c. A value of less than about 0.8 Pa-s at 2 sec;

11. The composition of claim 10, wherein said composition has an instant shear of:

a. A peak value from about 0.8 Pa-s to about 0.8 to about 8 Pa-s;

b. A value from about 0.05 to about 0.6 Pa-s at 1.2 sec;

c. A value from about 0.05 to about 0.4 Pa-s at 2 sec;

12. The composition of claim 1, wherein said organic solvent or hydrotrope is selected from the group consisting of alcohols, glycols, ethers, ether alcohols, and mixtures thereof.

13. An article of manufacture, wherein said article comprises:

a. a pump dispenser suitable for foaming;

b. a concentrated personal cleansing composition that is substantially free of organic solvent and hydrotrope, wherein said composition has a lather index greater than about 0.75, a dissolution value of less than about 200 sec, and comprises;

greater than about 30 wt % surfactant, wherein said surfactant is in the isotropic phase in said composition; and

greater than about 0.05 wt % conditioning agent.

14. The article of claim 13 wherein the Article further comprises a communication to the consumer, wherein said communication directs the consumer to use an appropriate amount of said composition based upon hair length or soil level.

15. A process for make decyl alcohol modified lauryl sulfate comprising the steps of:

(a) adding about 20 wt % by weight decanol to lauryl alcohol to form a mixture;

(b) feed the mixture to a falling film sulfator to combine with SO₃ gas to result in an acid mix;

(c) neutralize the acid mix with NaOH in a high shear mixer with sufficient water added to achieve the 38% active surfactant concentration.
