Abstract

A hand-washing method using an antimicrobial liquid hand soap which 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. A method of hand-washing comprising:

(a) providing an anti-microbial hand soap composition comprising;

(i) water;

(ii) a primary hand soap composition comprising;

1) at least two anionic surfactants; and

2) a biocide selected from the group consisting of halogenated aromatics and phenolics; and

(iii) from greater than 3 to less than about 20 wt % based on the combined dry weight of components (ii) and (iii) of a glutinous surfactant component selected from the group consisting of cocamidopropyl PG-dimonium chloride phosphate, dimer dilinoleamidopropyl PG-dimonium chloride phosphate, sodium grapeseed amidopropyl 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, wherein the glutinous surfactant has a relative contact angle value with water of at least about +10°

with respect to the primary hand soap composition, and alters the tactile properties of the primary soap composition;

(b) applying the anti-microbial hand-soap composition of (a) to the hands; and

(c) rinsing the hand soap composition from the hands with water.

2. The method according to claim 1, wherein the glutinous surfactant component comprises cocamidopropyl PG-dimonium chloride phosphate.

3. The method according to claim 1, wherein the glutinous surfactant component comprises dimmer dilinoleamidopropyl PG-dimonium chloride phosphate.

4. The method according to claim 1, wherein the glutinous surfactant component comprises sodiumgrapeseedamidopropyl PG-dimonium chloride phosphate.

5. The method according to claim 1, wherein the glutinous surfactant component comprises sodium olivamidopropyl PG-dimonium chloride phosphate.

6. The method according to claim 1, wherein the glutinous surfactant component comprises linoleamidopropyl PG-dimonium chloride phosphate.

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

8. The method according to claim 1, wherein the glutinous surfactant component comprises sunfloweramidopropyl phosphate PG-dimonium chloride.

9. The method according to claim 1, wherein the glutinous surfactant component has a relative contact angle value with water of at least about +2°

with respect to the primary soap composition.

10. The method according to claim 1, wherein the glutinous surfactant component is present in an amount of greater than 3% to about 10% based on the total weight of the composition.

11. The method according to claim 1, wherein the glutinous surfactant component is present in an amount of more than about 3% to about 7% based on the total weight of the composition.

12. The method according to claim 1, wherein the halogenated aromatic compound is:

13. The method according to claim 1, further comprising a chelating agent.

14. The method according to claim 1, wherein the composition further comprises glycerine.

15. A method of hand-washing comprising:

(a) providing an anti-microbial hand soap composition comprising;

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

(ii) a primary hand soap composition comprising;

1) at least two anionic surfactants; and

2) a biocide selected from the group consisting of halogenated aromatics and phenolics; and

(iii) greater than 3 wt % based on the total weight of the composition of a glutinous surfactant component selected from the group consisting of cocamidopropyl PG-dimonium chloride phosphate, dimer dilinoleamido-propyl PG-dimonium chloride phosphate, sodium grapeseed amidopropyl 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, wherein the glutinous surfactant has a relative contact angle value with water of at least about +10°

with respect to the primary hand soap composition, and alters the tactile properties of the primary soap composition;

(b) applying the anti-microbial hand-soap composition of (a) to the hands; and

(c) rinsing the hand soap composition from the hands with water.

16. A method of hand-washing comprising:

(a) providing an anti-microbial hand soap composition comprising;

(i) water;

(ii) a primary hand soap composition comprising;

1) at least two anionic surfactants; and

2) a biocide selected from the group consisting of halogenated aromatics and phenolics; and

(iii) from greater than 3 up to about 10 wt % based on the total weight of the composition of a glutinous surfactant component selected from the group consisting of cocamidopropyl PG-dimonium chloride phosphate, dimer dilinoleamido-propyl PG-dimonium chloride phosphate, sodium grapeseed amidopropyl 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, wherein the glutinous surfactant has a relative contact angle value with water of at least about +10°

with respect to the primary hand soap composition, and alters the tactile properties of the primary soap composition;

(b) applying the anti-microbial hand-soap composition of (a) to the hands; and

(c) rinsing the hand soap composition from the hands with water.

17. The method according to claim 16, wherein the hand soap composition contains from greater than 3 up to about 7 wt % glutinous surfactant.
