Definitions
- the invention relates to compositions comprising ether carboxylates, nonionic Surfactants and N-alkylpyrrolidones as well as other auxiliary substances.
- the compositions are characterized by a particular low foam level and at the same time lower Surface tension and high cleaning activity.
- the compositions do not contain cumene sulfonate as a solubilizer and can if necessary can also be formulated without solvents.
- the agents according to the invention become mechanical and manual cleaning of hard surfaces, especially of medical devices, surgical instruments, rigid and flexible Endoscopes, inventory and other inanimate surfaces are used.
- Surgical instruments are increasingly being machined today prepared special cleaning and disinfection machines.
- the cleaning step is particularly sensitive because it is residue-free Cleaning blood, secretion and protein contaminants prevents incrustations of residual contamination from the subsequent thermal or thermo-chemical Disinfection step. How difficult a mechanical residue-free Cleaning is actually done mostly on microsurgical Instruments and flexible endoscopes clearly, which is a complicated system of sometimes extremely narrow channels, branches and spindly cavities form.
- sensitive materials e.g. complicated optics, special adhesives, light guides, more sensitive to corrosion Metals and highly elastic plastics a particularly gentle treatment, the functionality of the sometimes very expensive devices even after many Processing cycles not to be affected.
- Alkaline cleaners attempt this task by adding active chlorine or to meet active oxygen compounds, which also without the addition of surfactants are able to solve protein contamination from surfaces.
- the disadvantage here is the high pH and the associated poor quality Material compatibility, especially compared to anodized aluminum, but also Nonferrous metals or special alloys. Therefore, in recent times, have increased mildly alkaline and pH neutral cleaners are suggested based on low-foam non-ionic and / or anionic surfactants are built up and Supporting the cleaning effect may contain proteolytic enzymes can.
- EP-A-0 268 227 describes a cleaning agent which contains at least one non-ionic low-foaming surfactant, complexing agents, proteolytic enzymes as well contains other detergent ingredients.
- nonionic surfactants Investment products of ethylene oxide and optionally propylene oxide saturated fatty alcohols claimed in which the terminal hydroxyl groups can be etherified, esterified or acetalized with an aliphatic alcohol.
- Comparable cleaning agents on this basis make themselves low Use the cloud point of the surfactants used.
- Such a detergent solution is usually clear at lower temperatures to become warm tarnish.
- This partial separation from the aqueous phase means that Surfactants mostly at temperatures above 25-30 ° C as foam inhibitors, see above that even mechanical cleaning processes with high turbulence without problems can be carried out.
- the aqueous phase becomes surface-active in this way Withdrawn substance, so that especially at higher temperatures 45 ° C increased wetting problems occur on the surfaces to be cleaned can and the cleaning effect of such a solution on the mechanical
- the strength of the solution remains limited. Provided the temperature of the cleaning solution but is still below the cloud point, can be in washing machines and disinfectors increased foaming occur, which in the case of cleaning from flexible endoscopes to automatic system shutdown and thus an interruption of the cleaning process due to pressure loss Can cause foaming.
- DE-A-196 07 530 describes a cleaner which, in addition to enzymes, complexing agents and other customary constituents, contains an anionic surfactant of the type of a short-chain C 5 -C 10 alkyl sulfate salt as the surfactant base. It is known that anionic surfactants have a good cleaning-supporting effect, surfactants with hydrophobic residues from 10 carbon atoms tend to form a lot of foam. If, as described in DE-A-196 07 530, surfactants with short-chain branched hydrophobic radicals are used, it is possible to produce formulations whose dilute solutions are characterized by a constant low foam formation over the entire temperature range, but strong in their wetting ability and cleaning activity to be desired.
- the surfactant base should have good biodegradability and for improvement no biologically hard fluorosurfactants are used come.
- the agent and its working solutions should preferably pH be neutral to slightly acidic to ensure optimal tolerance of the product and its solution compared to the usual flexible ones used in medicine Ensure plastic materials and metallic materials.

- initial attempts at formulation with octyl ether carboxylates showed that the cleaning solutions made from them tended to foam excessively.
- Attempts to contain the foam by using a blend with the particularly short-chain butyl ether carboxylate did not bring the hoped-for success, since the foam now disintegrated faster, but the initial foam height at time 0 remained almost unchanged.
