Abstract

Agents for disinfecting and/or deodorizing toilets and the like containing human or animal waste products combine an ordinary, known biocide with a vinyl compound.

Description

The invention relates to disinfectants for collective toilets and comparable installations, which are intended to absorb human and animal excreta.

Collective toilet systems are used for temporary storage of mostly human but also of animal excreta, where their disposal is not so is possible. Here are epidemic hygiene and odor problems.

Because a variety of infectious diseases are transmitted fecally-orally, such as diarrhea, Salmonellosis, typhoid fever, paratyphoid fever, dysentery, cholera and fungal diseases (candidoses). In addition, in decay processes both by aerobic and especially by anaerobically growing bacteria organic matter degraded so that as Metabolpro dukte volatile sulfur and nitrogen compounds such. For example, hydrogen sulfide, low levels of mercaptans, ammonia or methylamine are formed. These substances are not only Harmful, but also disturbing to disgusting. In addition, are leichtflüchti ge compounds already contained in fresh feces.

The problem affects many areas of private and public life: General To Aircraft toilets, toilets in buses and railways, mobile cottages for transport Sports and other events, for service areas and for the construction trade. Mobile Toi Latvians are also used in the private sector, such as camping and allotments. Likewise belong in this problem area collection containers for Monatshygieneartikel how they are found in many public toilets. Similarly, provide suction for Mucus, pus, blood and saliva in dental facilities with poor care a hygienic and odor problem.

A similar problem exists with regard to animal excretions, as in For example, incurred in the pork or poultry fattening in large quantities. If this Excretions are not removed for a long time or collected and stored There is a risk of transmitting infections of individual animals not only to the entire stock, but also to the staff employed in such establishments, if the existing germs are both human and animal pathogenic.  

About the epidemic hazard potential of these collection systems can be found in the Literature numerous publications, z. B. "Guide to Hygiene and Sanitation in Aviation", James Bailey, World Health Organization, Geneva, 1977 and 'Evaluation Reviews different toilet systems from a hygienic point of view ", W. Fluk, H.-G. Engler, Dr. W. Philipp, Federal Environmental Agency texts 32/92. Aldehydic preparations for the reduction of Infekti onsrisikos have been in use for some time. Especially the newer patents EP 0 620 013 A2 and EP 0 784 930 likewise address this problem and provide Solutions based on modern, strong-acting non-aldehyde biocides. you are particularly useful in the aircraft sector, as there are mainly on fast action to protect the disposal staff arrives.

Where it is due to their environmental hazard and the general health hazard when handling the chemicals is not possible, the putrefactive bacteria by strong we killing biocides, substances can be used that are primarily rotten intercept gases and ideally can inhibit the multiplication of bacteria without giving up to affect the health of the people and animals in contact with it. As Ge scavengers contain vinylogous carbonyl compounds, especially α, β-unsaturated Esters and carboxylic acids and α, β-unsaturated aldehydes, in question. This approach is especially in the private sector, ie z. B. for the disposal of camping toilets, to and described in DE 198 37 539.5.

Especially in the field of portable toilets or sanitary containers with a longer Service life and the frequenting by different people is a major "Deodorization" by odor trap, however, usually insufficient. Although a des infection according to WHO guidelines, d. H. complete killing of microorganisms within 15 minutes, not necessary here, as longer exposure times are possible. to On the other hand, by only a small addition of biocides, the odor does not be prevented.

Ideal especially for the public sector would be a product that only biocide so much Capacity brings to complete the microorganisms contained in the excreta To inhibit growth in growth or partially kill it, but in addition all from the excretions themselves as well as from their microbial decomposition coming easily reliably captures volatile substances.  

The solution is a mixture of biocides and vinylogous compounds, especially α, β-unsaturated esters, carboxylic acids and aldehydes. Surprisingly, it could be found that the two active principles complement each other, do not bother.

• - With the aldehydes, z. As formaldehyde, glutaraldehyde, succinaldehyde, glyoxal, the Phthalaldehydes, etc. are both the α, β-unsaturated esters and carboxylic acids as also the α, β-unsaturated aldehydes can be combined. Particularly advantageous are male and fumaric acid, which at the same time necessary for the stability of the aldehydes acidic environment citral, which at the same time gives off the strong smell of Al dehyde masked, since it is similarly volatile and therefore also in the "top note" sol mixture is present.
• - Equally broad is the possibility of combining quaternary ammonium compounds with the α, β-unsaturated compounds.
• - For the alkylamines commonly used in stool and instrument disinfection against the use of α, β-unsaturated aldehydes is limited. By Reaction of the two components resulting Schiff bases are still effective, however, they lead to formulation problems in liquid products, as they are no longer clearly soluble. Fumar and maleic acid, on the other hand, are ideal for Lowering of the highly alkaline pH of the amines in a weakly alkaline Area for improving the application properties (corrosion, toxicity).
• - Mixtures with peroxides are because of the possible formation of oxygen over the Solution in the airplane not advisable. DE 198 37 539.5 proposes peroxides de for use in z. For example, to use camping toilets at concentrations that the select aerobic bacteria. For use in the public mobile to be used but they are, for example, cottages or the storage of animal fecal matter also considered to be useful, while higher, all microorganisms impaired low concentrations are conceivable.

The advantage of the products thus invented lies in lower health and environmental risks and a lower price, because the amount of expensive and mostly dangerous Biocid is lowered, with simultaneously improved spectrum of action due to the additional Catch all odors with the safer and less expensive vinylogous verb fertilize. The bactericidal, virucidal and fungicidal activity, ie the speed and Completeness with which the microorganisms in the excreta are killed is depending on the proportion of the biocidal component. The ratio of the two components is adjustable in wide ranges, depending on the planned use and the desired strength  ke of the biocidal effect. Conceivable, however, are also blends with a full permanent disinfection necessary share of biocides and additionally vinylogous compounds, since so the excretions adhering to the complete killing of the microorganisms unpleasant smell is prevented. This allows for a more pleasant work for the operating personnel.

Both solid, pasty and liquid concentrates can be prepared on site by the user be diluted, as well as ready-mixes. The application of the invent Concentrates according to the invention are then diluted to 0.1 to 50%, advantageously 0.5 to 10%. The preparations may be mixed with the usual additives such as For example, surfactants, wetting agents, solvents, corrosion inhibitors, complexing agents, Stabilizers, buffers, defoamers, salts, thickeners, dyes, fragrances and similar.
