Abstract

An antimicrobial liquid hand soap composition includes: (a) water; (b) a primary hand soap composition; (c) a biocide; and (d) a glutinous surfactant having a relative contact angle value with water of at least about +10° with respect to the primary hand soap composition. The glutinous surfactant is present in an amount effective to alter the tactile properties of the primary soap composition to promote longer and more thorough hand washing by eliciting a response to the soap'"'"'s feel on the skin.

Claims

1. An antimicrobial liquid hand soap composition comprising:

(a) water;

(b) a primary hand soap composition which includes a biocide; and

(c) a glutinous surfactant component having a relative contact angle value with water of at least about +10°

with respect to the primary hand soap composition, the glutinous surfactant being present in an amount effective to alter the tactile properties of the primary soap composition, with the proviso that the glutinous surfactant is present in an amount of less than about 20 weight % based on the combined dry weight of the primary hand soap composition and the glutinous surfactant.

2. The antimicrobial hand soap according to claim 1, wherein the glutinous surfactant component is selected from the group consisting of:

cocamidopropyl PG-dimonium chloride phosphate;

dimer dilinoleamido-propyl PG-dimonium chloride phosphate;

sodiumgrapeseedamidopropyl PG-dimonium chloride phosphate;

sodium olivamidopropyl PG-dimonium chloride phosphate;

linoleamidopropyl PG-dimonium chloride phosphate;

PEG-8 dimethicone sunfloweramidopropyl PG-dimonium complex;

sunfloweramidopropyl phosphate PG-dimonium chloride and mixtures thereof.

3. The antimicrobial hand soap according to claim 1, wherein the glutinous surfactant component comprises cocamidopropyl PG-dimonium chloride phosphate.

4. The liquid hand soap according to claim 1, wherein the glutinous surfactant component comprises dimer dilinoleamidopropyl PG-dimonium chloride phosphate.

5. The liquid hand soap according to claim 1, wherein the glutinous surfactant component comprises sodiumgrapeseedamidopropyl PG-dimonium chloride phosphate.

6. The liquid hand soap according to claim 1, wherein the glutinous surfactant component comprises sodium olivamidopropyl PG-dimonium chloride phosphate.

7. The liquid hand soap according to claim 1, wherein the glutinous surfactant component comprises linoleamidopropyl PG-dimonium chloride phosphate.

8. The liquid hand soap according to claim 1, wherein the glutinous surfactant component comprises PEG-8 dimethicone sunfloweramidopropyl PG-dimonium complex.

9. The liquid hand soap according to claim 1, wherein the glutinous surfactant component comprises sunfloweramidopropyl phosphate PG-dimonium chloride.

10. The liquid hand soap according to claim 1, wherein the glutinous surfactant component has a relative contact angle value with water of at least about +20 with respect to the primary soap composition.

11. The liquid hand soap composition according to claim 1, wherein the glutinous surfactant component is present in an amount of from about 1% to about 10% based on the total weight of the composition.

12. The liquid hand soap composition according to claim 1, wherein the glutinous surfactant component is present in an amount of from about 3% to about 7% based on the total weight of the composition.

13. The liquid hand soap composition according to claim 1, wherein the primary soap composition comprises at least two anionic surfactants.

14. The liquid hand soap composition according to claim 1, wherein the primary soap composition comprises at least one nonionic surfactant.

15. The liquid hand soap composition according to claim 1, wherein the biocide comprises a halogenated aromatic compound.

16. The liquid hand soap composition according to claim 15, wherein the halogenated aromatic compound is:

17. The liquid hand soap composition according to claim 1, further comprising a chelating agent.

18. The liquid hand soap composition according to claim 1, wherein the composition further comprises glycerine.

19. An antimicrobial liquid hand soap composition comprising:

(a) up to about 75% by weight water;

(b) a primary hand soap composition including a biocide; and

(c) a glutinous surfactant component having a relative contact angle value with water of at least about +10°

with respect to the primary hand soap composition, the glutinous surfactant component being present in an amount effective to alter the tactile properties of the primary hand soap composition.

20. A liquid hand soap composition comprising:

(a) water;

(b) a primary hand soap composition; and

(c) a glutinous surfactant having a relative contact angle value with water of at least about +10°

with respect to the primary hand soap composition, present in an amount effective to alter the tactile properties of the primary soap composition, with the proviso that the glutinous surfactant is present in an amount of at least about 3% by weight and up to about 10% by weight based on the weight of the composition including water.

21. A liquid hand soap composition comprising:

(a) water present in an amount of up to about 75% by weight;

(b) a primary hand soap composition; and

(c) glutinous surfactant properties of the primary soap composition present in an amount of at least about 3% by weight and up to about 10% by weight based on the weight of the composition including water, the glutinous surfactant being operative to increase rinse time with respect to a like composition consisting of water and the primary soap composition.

22. The liquid hand soap composition operative to increase rinse time at least 10% with respect to a like composition consisting of water and the primary soap composition.

23. The liquid hand soap composition operative to increase rinse time at least 15% with respect to a like composition consisting of water and the primary soap composition.

24. The liquid hand soap composition operative to increase rinse time at least 20% with respect to a like composition consisting of water and the primary soap composition.

25. A method of formulating a hand soap composition comprising preparing a mixture of:

(a) water in an amount of up to about 75% by weight of the composition;

(b) a primary hand soap composition; and

(c) a glutinous surfactant wherein the glutinous surfactant is present in an amount of at least about 3% by weight and up to about 10% by weight based on the weight of the composition including water and wherein the glutinous surfactant alters the tactile properties of the composition so as to lengthen hand cleansing times.
