Abstract

Solid sanitizing compositions have advantages over corresponding liquids and powders. A solid sanitizing product can be contained within a plastic bottle with a label indicating that the contents have antimicrobial or deodorizing properties containing a non-flowable solid composition having greater than about 0.02 percent by weight antimicrobial compounds. The preferred solid sanitizing compositions consist essentially of an antimicrobial compound selected from the group consisting of quaternary ammonium salts, fatty amines and diamines, chlorhexidine gluconate, phenol, derivatives of phenol, parachloro metaxylenol and mixtures thereof, and between 0 and 99.98 percent by weight of a cleaning composition. The solid sanitizing compositions can be effectively used with solid dispensers. The solid dispensers have a bowl with a drain at the bottom and an upward pointing spray nozzle. The spray nozzle directs water into an inverted bottle of the sanitizing composition to produce an aqueous solution of sanitizing compounds which drains from the bottom of the bowl. A second source of aqueous solution or fresh water can combine with the solution draining from the bowl to product a more dilute solution of sanitizing compounds. The relative flow into the spray nozzle and the secondary source can be adjusted to produce a final diluted solution with a desired dilution. Antimicrobial solutions can be used in a variety of industrial and institutional applications including laundry and hard surface cleaning. Four methods of producing the solid sanitizing compositions are described.

Claims

1. A nonflowable disinfecting composition made by a process comprising the steps of:

forming a melt comprising

an alcohol alkoxylate selected from the group consisting of alcohol ethoxylates, alcohol propoxylates, and mixtures thereof,

an antimicrobial composition including an antimicrobial compound, the antimicrobial compound selected from the group consisting of quaternary ammonium compounds, and cationic surfactants other than quaternary ammonium compounds, and mixtures thereof, and

a quantity of urea,

thereby forming a liquid mixture of said alcohol alkoxylate, said antimicrobial composition and said urea;

pouring the liquid mixture of said alcohol alkoxylate, said antimicrobial composition and said urea into a container; and

cooling the liquid mixture of said alcohol alkoxylate, said antimicrobial composition and said urea, thereby forming the nonflowable disinfecting composition within the container.

2. The nonflowable disinfecting composition of claim 1, wherein the alcohol alkoxylate is a C_12-15 alcohol ethoxylate.

3. The nonflowable disinfecting composition of claim 1, in which the urea is present in an amount greater than the quaternary ammonium compound.

4. The nonflowable disinfecting composition of claim 1, in which said composition has an alkaline or neutral pH.

5. The nonflowable disinfecting composition of claim 1, in which said composition has an alkaline pH.

6. The nonflowable disinfecting composition of claim 1, in which the quaternary ammonium compound having antimicrobial properties is present in an amount greater than about 5% by weight.

7. The nonflowable disinfecting composition of claim 1, in which the quaternary ammonium compound is present in an amount between about 5% and 40% by weight.

8. The nonflowable disinfecting composition of claim 1, in which the quaternary ammonium is a salt which includes a quaternary nitrogen atom and at least one substituent alkyl group with a chain length ranging between about C₆ and C₂₀, the substituent alkyl group being bonded to the quaternary nitrogen atom.

9. The nonflowable disinfecting composition of claim 8, in which the quaternary ammonium salt is the chloride.

10. A nonflowable disinfecting composition made by a process comprising the steps of:

forming a melt comprising

an alcohol alkoxylate selected from the group consisting of alcohol ethoxylates, alcohol propoxylates, and mixtures thereof,

an antimicrobial composition including an antimicrobial compound, the antimicrobial compound selected from the group consisting of quaternary ammonium compounds, and cationic surfactants other than quaternary ammonium compounds, and mixtures thereof, and

a quantity of urea,

thereby forming a liquid mixture of said alcohol alkoxylate, said antimicrobial composition and said urea;

agitating the liquid mixture of said alcohol alkoxylate, said antimicrobial composition and said urea, and adding at least one cleaning agent selected from the group consisting of nonionic surfactants, anionic surfactants, alkaline builders, polyvalent metal sequestering agents and mixtures thereof;

pouring the resultant liquid mixture into a container; and

cooling said resultant liquid mixture, thereby forming the nonflowable disinfecting composition within the container.
