A solid block or unit dosed detergent composition as described which can be utilized in a variety of applications for cleaning surfaces and objects, removing suspending soils, and rinsing easily. The detergent composition, when exposed to an aqueous solution such as water, dissolves quickly and completely to create the use solution.

First claim

1 - 12 . (canceled)

13 . A solid detergent composition comprising:
an alkali metal carbonate in an amount effective to provide a use solution having a pH of at least about 8; 1 to 40 wt. % of a surfactant; a solidification agent; and at least 0.2 to 20 wt. % of a branched saturated fatty acid or a salt thereof having between 5 and 18 carbon atoms disintegrator selected from the group consisting of isopentanoic acid, neopentanoic acid, isohexanoic acid, neohexanoic acid, isoheptanoic acid, neoheptanoic acid, isooctanoic acid, neooctanoic acid, isononanoic acid, neononanoic acid, isodecanoic acid, neodecanoic acid, and salts and mixtures thereof; wherein the solid detergent composition has a dissolution rate when exposed to 4000 mL of aqueous solution at 155° F. of at least 30 g/minute.

14 . The solid detergent composition of claim 13 , comprising between 0.5 wt. % to 5 wt. % of the branched saturated fatty acid.

15 . The solid detergent composition of claim 13 , comprising between 5 wt. % to 20 wt. % of the branched saturated fatty acid disintegrator.

16 . The solid detergent composition of claim 13 , wherein the solidification agent comprises between 10 to 80 wt. % of sodium carbonate, sodium hydroxide or sodium metasilicate, or combinations thereof.

17 . The solid detergent composition of claim 13 , wherein the total composition has between 20 wt. % to 40 wt. % sodium carbonate.

18 . The solid detergent composition of claim 13 , wherein the total composition has between 20 to 40 wt. % sodium carbonate and 15 to 40 wt. % sodium hydroxide.

19 . The solid detergent composition of claim 13 , wherein the solid detergent composition is in the form of a tablet having a size between about 1 and about 50 grams.

20 . The composition of claim 13 , wherein the solid is formed by an extrusion process.

21 . The composition of claim 13 , wherein the solid is formed by a casting process.

22 . The composition of claim 13 , wherein the solid is formed by a tabletting process.

23 . The composition of claim 13 , wherein the branched saturated fatty acid has from 6 to 12 carbon atoms.

24 . The composition of claim 13 , wherein the branched saturated fatty acid has the general formula CH 3 (CH 2 ) m (CR 1 , R 2 , R 3 ) n (CH 2 ) o (CR 1 , R 2 , R 3 ) p (CH 2 ) q COOH, and wherein m, n, o, p and q are each an integer selected from 0-17, and n+p is 1 or 2.

25 . The composition of claim 24 , wherein o, p, and q are each zero.

26 . The composition of claim 25 , wherein R 1 is an alkyl and R 2 and R 3 are both hydrogen.

27 . The composition of claim 25 , wherein m is 3.

28 . The composition of claim 13 , wherein the surfactant comprises one or more cationic, anionic, nonionic, amphoteric or zwitterionic surfactants.

29 . The composition of claim 13 , wherein the surfactant comprises betaine, sodium alkylarylsulfonate, alpha-olefinsulfonate, fatty alcohol sulfate, alcohol ethoxylate, ethylene oxide/propylene oxide block copolymer, or combinations thereof.

30 . The composition of claim 13 , wherein the composition further comprises a water conditioning agent.

31 . The composition of claim 30 , wherein the water conditioning agent comprises EDTA, HEDTA, or a mixture thereof.

32 . The composition of claim 30 , wherein the water conditioning agent is present at about 1 to about 50 wt. %.

33 . The composition of claim 30 , wherein the water conditioning agent is present at about 3 to about 35 wt. %.

34 . The composition of claim 13 , wherein the composition is formulated for use in manual cleaning.

35 . The composition of claim 13 , wherein the composition is formulated for use as a pot and pan cleaner.

36 . The composition of claim 13 , wherein the composition is formulated for use in cleaning medical or dental instruments.

37 . The composition of claim 13 , wherein the composition is formulated for use in laundry.
