Abstract

An automatic dishwasher product comprising, in combination, a dispenser with openings therein and a water soluble solid composition positioned therein which comprises a high molecular weight polyethylene glycol, a non-ionic fatty acid alkanolamide, an oxyethylated alcohol, a non-ionic amine polyglycol condensate and, optionally, a fragrance, the measured release of said composition serving to increase detergent action and minimize spotting.

Claims

1. A solid composition of matter suitable for use as a cleansing or rinsing agent in an automatic dishwasher comprising

(a) from about 30-45%, by weight, of a polyethylene glycol or a blend of polyethylene glycols, said glycol or said blend thereof having a minimum molecular weight of about 4000;

(b) from about 15-25%, by weight, of a non-ionic solid, fatty acid alkanolamide having 10-24 carbon atoms in the fatty acid moiety;

(c) low foaming a non-ionic modified oxyethylated straight chain alcohol having 8-18 carbon atoms in the alcohol chain; and

(d) low-foaming a non-ionic ethylene diamine polyglycol condensate;

components (c) and (d) being present in a combined concentration of 30-55%, by weight, with the weight ratio of (c) to (d) ranging from 3;

1-1;

3.

2. A composition of claim 1 which also contains from 3-15%, by weight, of a fragrance.

3. The composition of claim 2, wherein the respective weight concentrations are 37-40% of (a), 17-20% of (b), 32-38% of (c) and (d), and 7-10% of fragrance.

4. The composition of claim 1, wherein component (a) is a polyethylene glycol having a molecular weight of 6,000.

5. The composition of claim 1, wherein component (b) is coconut monoethanolamide.

6. The composition of claim 1 which comprises:

40.50%, by weight, polyethylene glycol (MW=6,000)

19.50%, by weight, coconut monoethanolamide

19.69%, by weight, component (c)

15.31%, by weight, component (d)

5.00%, by weight, fragrance.

7. An automatic dishwasher product comprising, in combination, a dispenser having top, side and bottom surfaces with a plurality of openings therein and a solid, water soluble composition corresponding to claim 1 positioned therein, the area of said openings and the water solubility of said composition being selected so as to solubilize and release 0.5-2.0 grams of said composition when water at a temperature of from 40°

-80°

C. flows over the surface areas of said composition exposed through said openings.

8. The product of claim 7, wherein said composition also contains from 3-15%, by weight, of fragrance.

9. The product of claim 8, wherein the respective weight concentrations are 37-40% of (a), 17-20% of (b), 32-38% of (c) and (d), and 7-10% of fragrance.

10. The product of claim 7, wherein component (a) is a polyethylene glycol having a molecular weight of 6,000.

11. The product of claim 7, wherein component (b) is coconut monoethanolamide.

12. The product of claim 7, where said composition comprises:

40.50%, by weight, polyethylene glycol (MW=6,000)

19.50%, by weight, coconut monoethanolamide

19.69%, by weight, component (c)

15.31%, by weight, component (d)

5.00%, by weight, fragrance.

13. The product of claim 7, wherein said dispenser has a single opening in the top surface thereof having an area of 20 cm² and four openings in the side surface thereof having an area of from 0.6-2.5 cm² per opening.
