Abstract

A detergent composition includes: A. a co-polymer of diallyldimethylammonium chloride and acrylic acid in an amount of from about 0.05 to about 1 weight percent actives; B. sodium and/or potassium chloride in an amount of greater than about 0.5 up to about 5 weight percent actives; C. a surfactant component in an amount of from about 8 to about 30 weight percent actives and comprising: (1) an alcohol ethoxy sulfate in an amount of from about 0 to about 60 weight percent actives; (2) an alkoxylated alcohol in an amount of from about 0 to about 90 weight percent actives; (3) a linear alkylbenzene sulfonate in an amount of from about 0 to about 90 weight percent actives; wherein at least two of said (1) alcohol ethoxy sulfate, said (2) alkoxylated alcohol, and said (3) linear alkylbenzene sulfonate are present in an amount of greater than zero; and D. water.

Claims (37)

1. A detergent composition comprising:

A. a co-polymer of diallyldimethylammonium chloride and acrylic acid present in an amount of from about 0.2 to about 0.3 weight percent actives based on a total weight of said composition;

B. sodium and/or potassium chloride present in an amount of from about 1 up to about 5 weight percent actives based on a total weight of said composition;

C. a surfactant component present in an amount of from about 12 to about 13 weight percent actives based on a total weight of said composition and comprising:

(1) sodium laureth sulfate ethoxylated with about 2 to about 4 moles of ethylene oxide and present in an amount of from about 40 to about 50 weight percent actives based on a total weight of said surfactant component;

(2) a C12-C15 alcohol ethoxylate that is capped with about 7 moles of ethylene oxide present in an amount of from about 40 to about 50 weight percent actives based on a total weight of said surfactant component;

(3) a linear alkylbenzene sulfonate having a linear alkyl chain that has from about 10 to about 13 carbon atoms and present in an amount of from about 5 to about 15 weight percent actives based on a total weight of said surfactant component;

and

D. water present in a total amount of at least about 60 weight percent based on a total weight of said detergent; and

wherein said detergent composition has a turbidity of less than about 80 NTU measured at 25° C. when sodium chloride is utilized to the exclusion of potassium chloride, a turbidity of less than about 110 NTU measured at 25° C. when potassium chloride is utilized to the exclusion of sodium chloride, and a turbidity of less than about 100 NTU measured at 25° C. when both sodium and potassium chloride are utilized.

2. The detergent composition of claim 1 wherein:

the sodium and/or potassium chloride is present in an amount of from about 1 to about 2 percent actives based on a total weight of said composition.

3. The detergent composition of claim 1 wherein sodium chloride is utilized to the exclusion of potassium chloride.

4. The detergent composition of claim 3 having a turbidity of less than about 40 NTU measured at 25° C.

5. The detergent composition of claim 1 having a turbidity of less than about 40 NTU measured at 25° C.

6. A detergent composition consisting essentially of:

A. a co-polymer of diallyldimethylammonium chloride and acrylic acid present in an amount of from about 0.2 to about 0.3 weight percent actives based on a total weight of said composition;

B. sodium chloride present in an amount of from about 1 to about 2 weight percent actives based on a total weight of said composition;

C. a surfactant component present in an amount of from about 12 to about 13 weight percent actives based on a total weight of said composition and comprising:

(1) sodium laureth sulfate ethoxylated with about 2 to about 4 moles of ethylene oxide and is present in an amount of from about 40 to about 50 weight percent actives based on a total weight of said surfactant component;

(2) a C12-C15 alcohol ethoxylate that is capped with about 7 moles of ethylene oxide and is present in an amount of from about 40 to about 50 weight percent actives based on a total weight of said surfactant component; and

(3) a linear alkylbenzene sulfonate that has a linear alkyl chain that has from about 10 to about 13 carbon atoms and is present in an amount of from about 5 to about 15 weight percent actives based on a total weight of said surfactant component; and

D. water present in a total amount of at least about 60 weight percent based on a total weight of said detergent; and

wherein said detergent composition has a turbidity of less than about 72 NTU measured at 25° C.

7. The detergent composition of claim 1 wherein said sodium chloride is present in an amount of from about 1 to about 2 weight percent actives based on a total weight of said composition to the exclusion of potassium chloride.

8. The detergent composition of claim 1 wherein said detergent composition has a turbidity of less than about 72 NTU measured at 25° C.

9. The detergent composition of claim 1 wherein potassium chloride is utilized to the exclusion of sodium chloride.

10. The detergent composition of claim 1 wherein

(1) The sodium laureth sulfate is present in an amount of from about 43 to about 44 weight percent actives based on a total weight of said surfactant component;

(2) the C12-C15 alcohol ethoxylate is present in an amount of from about 44 to about 45 weight percent actives based on a total weight of said surfactant component;

(3) the linear alkylbenzene sulfonate is present in an amount of from about 11 to about 12 weight percent actives based on a total weight of said surfactant component.

11. The detergent composition of claim 10 wherein said sodium chloride is present in an amount of from about 1 to about 2 weight percent actives based on a total weight of said composition to the exclusion of potassium chloride.

12. The detergent composition of claim 10 wherein said detergent composition has a turbidity of less than about 72 NTU measured at 25° C.

13. The detergent composition of claim 10 wherein potassium chloride is utilized to the exclusion of sodium chloride.

14. The detergent composition of claim 1 wherein (1) the sodium laureth sulfate is present in an amount of from about 43 to about 44 weight percent actives based on a total weight of said surfactant component.

15. The detergent composition of claim 1 wherein (2) the C12-C15 alcohol ethoxylate is present in an amount of from about 44 to about 45 weight percent actives based on a total weight of said surfactant component.

16. The detergent composition of claim 1 wherein (3) the linear alkylbenzene sulfonate is present in an amount of from about 11 to about 12 weight percent actives based on a total weight of said surfactant component.
