Abstract

A mild, aqueous antimicrobial cleansing composition is disclosed which contains little or no volatile alcohol and does not leave a sticky residue during drying. The composition may be used alone or in combination with shampoos, lotions, body cleansers, and the like. In another embodiment, impregnating a water insoluble substrate with the inventive composition provides a disposable wipe. The process of making and using the inventive wipe is also described.

Claims

1. An aqueous, mild, antimicrobial cleansing composition, comprising:

a. an effective amount of a water soluble or dispersible antimicrobial agent, or a precursor or salt thereof;

b. a nonionic surfactant; and

wherein said composition contains less than 1% of any compound selected from the group consisting of an amphoteric surfactant, an anionic surfactant, a halogenated aromatic hydrocarbon, an amide, and a volatile alcohol with a boiling point of under 210°

C.

2. The composition of claim 1 wherein said antimicrobial agent is a cationic compound, or a salt or precursor thereof.

3. The composition of claim 2 wherein said cationic compound is a quaternary ammonium compound having at least one aromatic group.

4. The composition of claim 3 wherein said aromatic quaternary ammonium compound is selected from the group consisting of benzethonium chloride, benzalkonium chloride and methyl benzethonium chloride.

5. The composition of claim 3 wherein said aromatic quaternary ammonium compound is present in a concentration range of 0.05 to 0.5 weight percent.

6. The composition of claim 1 wherein the nonionic surfactant is selected from the group consisting of a condensation product of a saccharide polymer and a C8 to C12 alcohol.

7. The composition of claim 6 wherein the nonionic surfactant is selected from the group consisting of decyl glucoside, lauryl glucoside, coco-glucoside and mixtures thereof.

8. The composition of claim 1 wherein the composition does not contain any compound selected from the group consisting of an amphoteric surfactant, an anionic surfactant, a halogenated aromatic hydrocarbon, an amide, and a volatile alcohol with a boiling point of under 210°

C.

9. The composition of claim 1 wherein said composition contains a benefit agent.

10. The composition of claim 9 wherein said benefit agent is selected from the group consisting of a polyhydric alcohol, a polyol, vitamins, skin emollients and anti acne compounds.

11. A mild antimicrobial, cleansing wipe, comprising:

a. a water insoluble substrate;

b. an aqueous, mild, antimicrobial cleansing composition, said composition including an effective amount of a water soluble or dispersible bactericidal agent, or a precursor or salt thereof; and

a nonionic surfactant; and

wherein said composition contains less than 1% of any compound selected from the group consisting of an amphoteric surfactant, an anionic surfactant, a halogenated aromatic hydrocarbon, an amide, and a volatile alcohol with a boiling point of under 210°

C.

12. The wipe of claim 11 wherein the water insoluble substrate is selected from the group consisting of wet-laid, hydroentangled, meltblown or air-laid nonwovens.

13. The wipe of claim 11 wherein said bactericidal agent is a quaternary ammonium compound, or a salt or precursor thereof.

14. The wipe of claim 13 wherein said quaternary ammonium compound has at least one aromatic group.

15. The wipe of claim 14 wherein said aromatic quaternary ammonium compound is selected from the group consisting of benzethonium chloride, benzalkonium chloride and methyl benzethonium chloride.

16. The wipe of claim 14 wherein said aromatic quaternary ammonium compound is present in a concentration range of 0.05 to 0.5 weight percent.

17. The wipe of claim 11 wherein the nonionic surfactant is selected from the group consisting of a condensation product of a saccharide polymer and a C8 to C12 alcohol.

18. The wipe of claim 17 wherein the nonionic surfactant is selected from the group consisting of decyl glucoside, lauryl glucoside, coco-glucoside and mixtures thereof.

19. The wipe of claim 11 wherein the composition does not contain any compound selected from the group consisting of an amphoteric surfactant, an anionic surfactant, a halogenated aromatic hydrocarbon, an amide, and a volatile alcohol with a boiling point of under 210°

C.

20. The wipe of claim 11 wherein said composition contains a benefit agent.

21. The wipe of claim 11 wherein said benefit agent is selected from the group consisting of a polyhydric alcohol, a polyol, vitamins, skin emollients sunscreen compounds and anti-acne compounds.

22. The process of making a mild antimicrobial, cleansing wipe, comprising the step of coating a water insoluble substrate with an aqueous, mild, antimicrobial cleansing composition, said composition including an effective amount of a water soluble or dispersible bactericidal agent, or a precursor or salt thereof;

and a nonionic surfactant; and

wherein said composition contains less than 1% of any compound selected from the group consisting of an amphoteric surfactant, an anionic surfactant, a halogenated aromatic hydrocarbon, an amide, and a volatile alcohol with a boiling point of under 210°

C.

23. The process of making a mild antimicrobial, cleansing wipe, comprising the step of coating a water insoluble substrate with an aqueous, mild, antimicrobial cleansing composition, said composition including an effective amount of a water soluble or dispersible bactericidal agent, or a precursor or salt thereof;

and a nonionic surfactant; and

wherein said composition contains less than 1% of a compound selected from the group consisting of an amphoteric surfactant, an anionic surfactant, a halogenated aromatic hydrocarbon, an amide, and a volatile alcohol with a boiling point of under 210°

C.

24. The process of using a mild antimicrobial, cleansing wipe, comprising the step of applying the wipe to the skin to remove dirt and oil, said composition including an effective amount of a water soluble or dispersible bactericidal agent, or a precursor or salt thereof;

and a nonionic surfactant; and

wherein said composition contains less than 1% of a compound selected from the group consisting of an amphoteric surfactant, an anionic surfactant, a halogenated aromatic hydrocarbon, an amide, and a volatile alcohol with a boiling point of under 210°
