DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a surface disinfectant and cleaning composition, which contains a biocidal agent, a tenside and a solvent.
In a plurality of areas accessible to the public, such as means of transport, restaurants and, in particular, hospitals, homes, medical practises, and the like, it is necessary that those areas the people present there come into contact with should be freed from undesirable microorganisms. For this purpose, surface disinfectants are used which are frequently also combined with cleaning compositions and contain as a biocidal agent, for example, low-molecular alcohols, such as ethanol or propanol. These alcohols must be present in high concentration in order that they can develop their biocidal effect, as a result of which high concentration a fire hazard may occur and the surfaces treated with this disinfectant may be affected, for example, in that significant components are dissolved away, discoloration occurs, or the like.
From EP-A-0 384 126 there is known such a sprayable surface disinfectant based on lower aliphatic alcohols and anionic tensides, which contains a mixture of methyl alcohol and isopropanol, anionic tensides, an acidifier for adjustment of a pH value between 2 and 6, or an alkalizing agent for adjustment of a pH value between 8 and 12, the balance being water. This combination is said to be a composition, which rapidly achieves a bactericidal and fungicidal effect, exhibits good cleansing action and displays in spite of the purposefully low alcohol content good materials compatibility and a relatively high flash point and involves relatively quick drying and a low formation of residues.
DE-A-39 14827 describes a liquid disinfectant concentrate, which contains as a biocidal agent an active oxygen component, viz peroxymonosuiliric acid and/or the salts thereof, in addition to a tenside component and water as well as conventional additives.
It has been found that, when using the customary surface disinfectant and cleaning compositions, problems will occur specifically when synthetic material surfaces must be disinfected and cleaned. A particularly difficult situation arises in medical practises, and specifically, in dental practises where, due to legal provisions, a wide range of areas must be disinfected, specifically the treatment unit and the furniture and equipment. In surface disinfection of dental treatment units a problem arises from the fact that a wide variety of materials are used. The upholstery materials used must have a closed-cell surface so as to prevent germs from penetrating whereby they must usually consist of an integral foam, which is adhered onto a foam core. When treating such upholstery materials with an alcohol-containing disinfectant, often the plasticizers, colorants and stabilizers contained in the synthetic material are dissolved out, in consequence of which the surface coverings which often have been dyed pastel-colored turn unattractive, become discolored, or display cracks, very soon.
Difficulties arise also from the fact that in the case of the instrument trays which are often made of polycarbonate the disinfectants will cause cracks and discoloration, particularly in undercuts with metal threads inserted therein, which undercuts are difficult to reach. As a result of this, on account of the permanent treatment with the surface disinfectants changes of the surfaces of the materials treated will occur after a rather short time, which changes will be tolerated neither by personnel nor by patients.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an efficient surface disinfectant and cleaning composition, which develops a strong disinfecting action against the germs usually encountered and provides a high tensidic cleaning effect while at the same time not causing any changes, discoloration or destruction of the surfaces of the synthetic materials treated therewith even when applied for a prolonged period of time.
It has been found that this object can be accomplished
