Field of the invention
The invention relates to a solid composition comprising alkylamines suitable for use for a cleaning agent and disinfection agent, in particular for use for disinfection of surfaces in the food and beverage processing industry and/or as a lubricant in the beverage and other processing industry.
Background of the invention:
Concentrated aqueous liquid cleaning and disinfection products are used throughout residential and commercial properties in a variety of applications including the cleaning and disinfection of surfaces receiving beverages or foodstuff or other residues. The use of concentrated liquids has the disadvantage of being bulky due the high water content and potentially hazardous if spilled due to the high concentration of the active cleaning components such as peroxides and/or concentrated alkaline or acidic components.
The European patent application EP 1 196517 (ECOLAB) discloses the use of an aqueous liquid concentrate of amines and amphotensides for cleaning and/or disinfecting purposes. Further, EP 1 196517 (ECOLAB) discloses an aqueous liquid lubricant concentrate for filling facilities for beverages or foodstuffs or other residues. The concentrated aqueous liquid lubricant is not ready for use and needs to be diluted by adding additional water before use. The European patent application EP 1458418 (ECOLAB) discloses a thickened, ready for use liquid disinfectant for medical or dental suction apparatus, which includes an active substance selected from the group of alkylpropylenediamines with a defined viscosity of about 1000 mPas and a thickening agent being included as additional component. The European patent application EP 0714434 (ECOLAB) discloses solid cleaners for removing fatty soils usable for hard surfaces, cooking utensils, laundry and other substrates. The solid cleaners contain a blend of surfactants comprising alkyldimethylamineoxide combined with an anionic sulfonate. The solid cleaners disclosed in EP 0714434 are used for the removal of vegetable and animal fat. However, the alkyldimethylamineoxides disclosed in EP 0714434 are not known to be used for disinfection properties, because they have practical no or at most a poor disinfection activity only. Further, EP 0714434 (ECOLAB) does not disclose lubricants.
There also is still the problem of replacing peroxyacetic acid in liquid and solid compositions due to the higher safety conditions for storing and transportation. Further, the peroxyacetic acid has a pungent acidic odor even in diluted form.
Moreover, concentrated liquid solutions and solid compositions with a high concentration of active ingredients for use for a cleaning agent, as disinfection agent and/or as lubricant have an unpleasant pungent odor.
There is a need for a solid cleaning and disinfecting product and/or a solid lubricate product with a high content of active ingredients for use in residential, commercial, and industrial applications that after dissolution effectively cleans, disinfects and/or lubricates at the same time.
In particular, there is still the need to substitute concentrated liquid compositions of being bulky due to its water content. Further, concentrated liquid compositions as well as solid cleaning, disinfection and/or lubricant compositions have an unpleasant pungent odor and are hazardous or irritating to the skin in concentrated liquid or solid form due to the high concentration of active ingredients such as peroxides, chlorines, or suchlike.
The object of the present invention is to avoid the disadvantages mentioned above for concentrated liquids and solid compositions with a high concentration of active ingredients for use for a cleaning agent, disinfection and lubricant.
The object of the present invention is to provide a composition with a high concentration of active ingredients that is solid at temperatures below +45° C for use for a cleaning agent, disinfection agent and lubricant in an efficient way with the benefit of having a significant reduced pungent odor and being less bulky, more stable at storage, and less hazardous to the user.
Detailed description of the invention The object of the present invention is solved by a solid composition described in detail below, which provides good cleaning, disinfecting and/or lubrication properties and shows much lower skin irritation and significant reduced pungent odor compared to concentrated liquid or solid compositions comprising peroxyacid.
Using solid compositions with a high concentration of active ingredients instead of concentrated liquid products, results in the safety, health and environmental aspects become dramatically better. This is especially the case in dairy farms, where e.g. children can come into contact with said composition very easily.
With a solid composition of the present invention, it is possible to save a lot of storage space and transport costs. The volume of the solid composition compared to a concentrated liquid equivalent can be reduced for example to at least 80%.
The solid composition of the present invention comprises the active ingredients in a high concentration. The concentration of the active ingredients is calculated on the total weight of the solid composition of the present invention, if not otherwise stated. Before use, the solid composition of the present invention needs to be dissolved in an aqueous solution, preferably water, to obtain a ready-to-use solution. Preferably, the solid composition can be dissolved at the time of application and/or stored in a dilution device. Another advantage of replacing peroxyacetic acid in liquid and solid compositions by alkylamine of mono-, di- and/or polyamines is that the alkylamine of mono-, di- and/or polyamines are sufficient stable for at least one year. Contrary thereto, peroxyacetic acid after it has been formed shows a tendency to decompose. Thus, the concentration of peroxyacetic acid decreases over the time of use. A comparison of a solid composition, a concentrated solution and/or a ready-to-use solution of the present i nvention with a peroxyacetic acid containing solid composition, a peroxyacetic acid containing concentrated solution and/or a peroxyacetic acid containing ready-to-use solution shows a significant reduction of the active component peroxyacetic acid, where else the concentration of the active alkylamine component of mono-, di- and/or polyamines remains practically stable. The benefit of the solid composition, the concentrated solution and/or the ready-to-use solution of the present invention is, that the concentration as well as the disinfecting effect remains stable over the time of use.

Depending on the desired need the concentrated solution and/or ready-to-use solution can be flushed-out at once or portion-wise. Preferably, a concentrated solution is flushed-out from the dispensing chamber and is subsequently diluted to the ready-to-use solution. Instead of flushed-out the concentrated solution and/or ready-to-use solution can be sprayed.
In case of spraying portion-wise, for example 15 liter of a concentrated solution and/or a ready-to-use solution, the spraying cycle takes place for about 4 h to 5 h and spraying is for 1 min to 2 min and stop for 20 sec to 30 sec before repeating the process.
Preferably, the temperature of the concentrated solution and/or the ready-to-use solution may remains constant and is at least > 0° C.

Still an object of the invention is directed to the use of the solid composition, the concentrated solution and/or the ready-to-use solution.
The solid composition, the concentrated solution and/or the ready-to-use solution can be used for cleaning and disinfecting of beverage, foodstuff and other residues containing and/or contacting facilities. In particular, the solid composition, the concentrated solution and/or the ready-to-use solution can be used for cleaning and disinfection of food and/or beverage container, medical instruments, hard surfaces and/or soft surfaces as well as a lubricant. The lubricant can be used in the food and beverage industry, especially in automatic chain and belt lubricating installations. In particular, the ready-to-use solution obtained from the solid composition and/or the concentrated solution can be used for lubricating chain belts and/or filling facilities for containers receiving beverages, foodstuffs or other materials whereby the containers are conveyed on conveying devices and brought into contact with an aqueous ready-to-use solution of a solid composition according to the invention. The grade of aqueous dilution of the lubricant composition may differ with respect to the materials of the band-conveyor systems to be lubrified, such as stainless steel and/or plastic or there like.
The conveying devices and/or the devices connected thereto can be cleaned and/or disinfected at preselected time intervals and without interrupting the filling and conveying operation by using the solution for cleaning and/or disinfecting as well as lubricated, wherein the ready-to-use solution differs in concentration from the lubricant ready-to-use solution. For example, a concentrated solution of the present invention can be used as at least one source and depending of its place of use the ready-to-use solution can then be individually diluted to its desired concentration.
It may be preferred that the ready-to-use solution is a cleaning, disinfection agent and lubricant at once. With other words, the ready-to-use solution may provide a cleaning, disinfection and lubrication effect at the same time. However, the solid composition according to the invention with all advantages for storage, transport and hazardous can also be used as lubricating agent only. Most preferred is the use of the solid composition, the concentrated solution and/or the ready-to-use solution for cleaning and disinfecting of milk containing and/or contacting facilities, such as present on a dairy plant, for example a milking device comprising milk vessel and/or milking robots. A milking device can be cleaned and disinfected by providing a concentrated solution from a solid composition of the present invention. For example, a solid composition of the present invention of 3.2 kg can be placed in a dispensing container. Into the container about 15 I water is added and recirculated to completely dissolve said solid capsule. The water to dissolve the solid composition of the present invention is used in a closed loop. The solid capsule is dissolved in water for a cycle of 1 min to 2 min. Then, the water is flushed-out and returned through a spraying-nozzle with stop intervals of 20 sec to 30 sec, whereby the temperature of the water remains constant and is at least≥ 5 °C. The recirculation of the concentrated solution ensures that the solution remains homogeneous.
A suitable product dispenser is SOLVEXX CUBE available from ECOLAB ® .
The concentrated solution can be further diluted in the application apparatus, such as milking device or milking robot, to obtain the ready-to-use solution.
Preferably, the ready-to-use solution can be used to clean and/or disinfect the teat brushes of a milking robot.

POAA stands for peroxyacetic acid. The concentration in ppm means the total concentration of cocopropylenediamine and the in situ produced POAA in the ready-to-use solution, based on the total amount of said solution.
Table 5 clearly shows that a minor concentration of amine (ppm) has an improved
disinfection effect compared to a ready-to-use solution containing POAA.
Conclusion
The solid composition and the ready to use composition provide improved cleaning, disinfecting and lubrication properties and show much lower skin irritation and significant reduced pungent odor compared to concentrated liquid or solid peroxyacid comprising compositions. Additionally the solid technology is an economic way of handling chemistry in form of lower packaging volumes, transport volumes and storage.
