Abstract

A detergent composition particularly useful in aqueous solutions for cleaning soiled surfaces. The formulation which may be in either dry or concentrate form, includes alkaline builders, wetting agents, and a flocculant, and may in certain instances, include a floatation agent. As an alkaline builder, sodium tripolyphosphate is normally preferred, while others such as mixtures of sodium tripolyphosphate with sodium sulphate or potassium hydroxide and soda ash may also be successfully utilized. The formulation is preferably applied to the surface as an aqueous solution in relatively heavy or thick layers, with agitation to permit the removed soilage to create flocs, and with the flocculated soilage being floated away from contact with the surface for facilitating removal.

Claims

1. A detergent composition consisting essentially of a formulation prepared with the following composition:

space="preserve" listing-type="tabular">______________________________________ Component Content ______________________________________ (a) an alkaline builder selected from the group consisting of sodium tripolyphosphate, mixtures of sodium tripolyphosphate with an alkaline agent selected from the group consisting of potassium hydroxide, sodium sulfate and sodium carbonate;

2. The detergent composition as set forth in claim 1 wherein a floatation agent consisting essentially of sodium alkyl aryl sulfonate is present in an amount ranging from between about 1% and 10% by weight of the total weight of alkaline builder, wetting agent and flocculant, said floatation agent having the structural formula:

##STR2## wherein R is an alkyl chain having from between about 11 and 13 carbon atoms.

3. The detergent composition as set forth in claim 1 wherein said alkaline builder is selected from the group consisting of sodium tripolyphosphate, potassium hydroxide, sodium carbonate, and combinations thereof.

5. The detergent composition as set forth in claim 1 wherein said flocculant is present in said formulation in an amount ranging from between about 25 to 40% by weight of the combined weight of the alkaline builder and wetting agent present.

6. The detergent composition as set forth in claim 1 wherein said alkaline builder includes sodium tripolyphosphate present in said formulation in a range of from between about 18 and 30% by weight of the total weight of alkaline builder, wetting agent and flocculant.

7. A detergent composition consisting essentially of a formulation prepared with the following composition:

space="preserve" listing-type="tabular">______________________________________ Component Content ______________________________________ (a) an alkaline builder selected from the group consisting of sodium tripolyphosphate, mixtures of sodium tripolyphosphate with an alkaline agent selected from the group consisting of potassium hydroxide, sodium sulfate and sodium carbonate;
