Homogeneous laundry detergent slurries containing amphoteric surface-active agents

A stable, homogeneous, aqueous detergent slurry consisting essentially of:

• a. a sodium polyphosphate in amounts of from about 14 weight percent to about 30 weight percent,
• b. an alkali metal hydroxide or alkali metal salt selected from the group consisting of sodium carbonate, sodium hydroxide, sodium bicarbonate, potassium hydroxide, potassium carbonate, potassium bicarbonate, sodium sesquicarbonate, potassium sesquicarbonate, sodium borate, potassium borate, potassium sulfate, sodium sulfate, sodium chloride, potassium chloride, sodium orthophosphate, tetrasodium pyrophosphate and tetrapotassium pyrophosphate in amounts of from about 1 weight percent to about 5 weight percent,
• c. a soluble, anionic surface-active agent selected from the group consisting of alkyl-, alkylaryl-, alkene-sulfate salts and alkyl-, alkylaryl-, and alkene-sulfonate salts,
• d. a soluble, anionic surface-active agent which is an alkali metal alcohol alkoxylate sulfate in amounts of about 0 to about 5 weight percent,
• e. sodium carboxymethylcellulose in amounts of from about 0.1 to about 1 weight percent,
• f. an amphoteric surface-active agent selected from the group consisting of N-coco .beta.-amino propionic acid;
• N-lauryl-, myristyl .beta.-amino propionic acid;
• disodium N-tallow .beta.-iminodipropionate;
• N-coco .beta.-amino butyric acid;
• and coco betaine in amounts of about 0.5 to about 5 weight percent,
• g. said sodium polyphosphate being present in part as insoluble particles having an average diameter of about 1 to 10 microns, and
• h. the total amount of the above surface-active agents in said detergent slurry being from about 13 weight percent to about 20 weight percent.
