Abstract

A detergent composition as described which can be utilized in a variety of applications for cleaning surfaces and objects, removing suspended soils, and rinsing easily. The detergent composition is particularly effective at removing soils caused by raw fish soil.

First claim

What is claimed is:

1. A solid detergent composition comprising:
an alkaline source consisting of alkali metal carbonate in an amount effective to provide a use solution having a pH of at least about 9.5;
water conditioning agent in an amount of about 1 to 50 wt. %;
an active agent consisting essentially of a branched fatty acid represented by the formula CH 3 (CH 2 ) m (CR 1 R 2 ) n (CH 2 ) o (C R 1 R 2 ) p (CH 2 ) q COOH wherein m, n, o, p and q are each an integer selected from 0-17, and n+p is 1 or 2, and m+n+o+p+q is between 3 and 18 and wherein R 1 and R 2 are independently a hydrogen or alkyl group with at least one being an alkyl group or combinations thereof;
a solidification agent consisting of alkali metal carbonate and alkali metal bicarbonate;
water in an amount of about 1 wt. % to about 5 wt. %; and
wherein the solid detergent composition is substantially free of chlorine.

2. The solid detergent composition of claim 1 , wherein the active agent is a salt of a branched fatty acid, the fatty acid represented by the formula CH 3 (CH 2 ) m (CR 1 R 2 ) n (CH 2 ) o (C R 1 R 2 ) p (CH 2 ) q COOH wherein m, n, o, p and q are each an integer selected from 0-17, and n+p is 1 or 2, and m+n+o+p+q is between 6 and 12 and wherein R 1 and R 2 are independently a hydrogen or alkyl group with at least one being an alkyl group.

3. The solid detergent composition of claim 1 , wherein the active agent is a C 8 - C 12 branched fatty acid.

4. The solid detergent composition of claim 1 , wherein the active agent is a sodium or potassium salt of a branched fatty acid selected from the group consisting of sodium isononanoate, sodium isooctanoate, sodium neodecanoate, sodium neopentanoate, sodium neoheptanoate, or mixtures thereof.

5. The solid detergent composition of claim 1 , wherein the active agent is a salt of a branched fatty acid consisting of sodium isononanoate.

6. The solid detergent composition of claim 1 comprising between 1 wt. % to 3 wt. % of branched fatty acid active agent.

7. The solid detergent composition of claim 1 , wherein the solidification agent consists of between 10 to 80 wt. % of sodium carbonate.

8. The solid detergent composition of claim 1 , wherein the total composition has between 30 to 60 wt % sodium carbonate and is substantially free of sodium hydroxide.

9. The solid detergent composition of claim 1 , wherein the solid detergent composition is in the form of a block having a size of at least about 5 pounds.

10. The solid detergent composition of claim 1 wherein the pH of a use solution is between about 9.5 and 11.

11. The solid detergent composition of claim 1 further comprising lipase, cutinase, peroxidase, or gluconase, or combinations thereof.

12. A method for cleaning a hard surface, comprising the steps of:
a) providing a use solution comprised of water and a detergent concentrate, the detergent concentrate comprised of a detergent composition comprising:
an alkaline source consisting of an alkali metal carbonate in an amount effective to provide a use solution having a pH of at least about 9.5;
water conditioning agent in an amount of about 1 to 50 wt. %;
water in an amount of about 1 wt. % to about 5 wt. %;
an active agent selected from the group consisting of sodium isononanoate, isononanoic acid, sodium isooctanoate, isooctanoic acid, sodium neodecanoate, neodecanoic acid, sodium neopentanoate, neopentanoic acid, sodium neoheptanoate, neoheptanoic acid, 3,5,5-trimethylhexanoic acid, 6-methyl-heptanoic acid, 2,2-dimethyloctanoic acid, neopentanoic acid (2,2-dimethylpropanoic acid), 2,2-dimethylpentanoic acid, and salts thereof, or mixtures thereof;

b) applying the use solution to a hard surface containing fish soil; and
c) rinsing the surface thereby removing the fish soil from the hard surface.
