Description:CROSS-REFERENCE TO RELATED APPLICATIONS This is a continuation application of PCT/EP02/10817, filed Sep. 26, 2002, which claims the benefit of DE 101 47 186.6, filed Sep. 25, 2001. FIELD OF THE INVENTION The present invention concerns activ

23、e ingredient combinations comprising polyhexamethylene biguanidine hydrochloride and distearyidimethylammonium as well as the use of active ingredient combinations as agents against bacteria, mycota and viruses, in particular for preserving cosmetic and dermatological emulsions. In particular embodi

24、ments, the present invention concerns preparations, preferably cosmetic and dermatological preparations containing such substances. BACKGROUND OF THE INVENTION Healthy warm-blooded organisms, in particular healthy human skin, are colonized by a wide variety of nonpathogenic microorganisms. These so-

25、called microflora of the skin are not only harmless, but also represent an important form of protection as a defense against opportunistic or pathogenic microbes. Bacteria belong to the prokaryotic single-celled organisms. They can be crudely distinguished according to their shape (ball, cylinder, b

26、ent cylinder) as well as the structure of their cell wall (gram-positive, gram-negative). The physiology of the organisms also allows for finer distinctions. There thus exist aerobic, anaerobic and facultatively anaerobic bacteria. Many individuals are of medical significance owing to their characte

27、ristic as pathogenic microbes, while others are completely harmless. Substances effective against bacteria have been known for some time now. Nevertheless, many of these antibacterial agents are not suitable for all medical, let alone cosmetic, applications, as the metabolic functions of the warm-bl

28、ooded organism, in other words the diseased patient, are also affected by the application in one way or another. Gram-negative microbes are typically Escherichia coli, Pseudomonas species as well as enterobacteria such as Citrobacter freundii. Even gram-positive microbes play a role in cosmetics and

29、 dermatology. Thus, for example, bacterial secondary infections are also of etiological significance besides other influences. One of the most important microorganisms associated with unclean skin is Staphylococcus aureus . This is responsible for the symptoms Impetigo follicularis, furunculosis, ab

30、scesses, sepsis, pemphigus neonatorum, toxic shock syndrome, food poisoning etc. In addition to this, examinations have revealed that a high percentage (over 90% of those affected) of neurodermatitis patients exhibited an, in part, extremely high content of Staphylococcus aureus on the skin. In cont

31、rast to bacteria, fungi (also referred to mycota or mycobionts) belong to the eukaryotes. In contrast to the so-called prokaryotes (procytes), eukaryotes are living organisms whose cells (eucytes) have a cell nucleus separated from the remaining cytoplasm by a nuclear envelope and nuclear membrane.

32、The cell nucleus contains the genetic information stored in chromosomes. Typical representatives of the mycobionts include yeasts ( Protoascomycetes ), moulds ( Plectomycetes ), mildews ( Pyrenomycetes ), false mildews ( Phycomycetes ) and mushrooms or toadstools ( Basidiomycetes ). Fungi do not bel

33、ong to the Plant Kingdom, but like plants have a cell wall as well as vacuoles filled with cell sap and plasma streaming clearly visible microscopically. They do not contain any photosynthetic pigments and are C-heterotroph. They grow under aerobic conditions and obtain energy through oxidation of o

34、rganic substances. Several representatives, for example yeasts, are facultative anaerobes and capable of obtaining energy through fermentation processes. Dermatomycoses are diseases in which certain species of fungi, in particular dermatophytes, penetrate the skin and hair follicles. Typical symptom

35、s of dermatomycoses are vesicles, exfoliation, fissures and erosion, usually accompanied by itching or allergic eczema. Dermatomycoses can essentially be divided into four groups: Dermatophyes (e.g. epidermophytosis, favus, microsporosis, trichophytosis), yeast mycoses (e.g. pityriasis and other myc

36、oses caused by pityrospores, Candida infections, blastomycosis, Busse-Buschke disease, torulosis, piedra alba, torulopsosis, trichosporosis), mould mycoses (e.g. aspergilosis, cephalosporiosis, phycomycosis and scopulariopsis ) and system mycoses (e.g. chromomycosis, coccidiomycosis (Posada's di

37、sease) or histoplasmosis). The pathogenic microbes typically include Candida species from the yeast group (e.g. Candida albicans ) and those of the Pityrosporum family. Pityrosporum species, in particular Pityrosporum ovale , are responsible for skin diseases such as Pityriasis versicolor, Seborrhea

38、 in the forms Seborrhea oleosa and Seborrhea sicca which are primarily manifested as Seborrhea capitis (dandruff), seborrheic eczema and Pityrosporum folliculitis . An involvement of Pityrosporum ovale in the development of psoriasis is currently under discussion in the medical world. All regions of

39、 the human skin can be affected by dermatomycoses. Dermatophytes almost exclusively attack the skin, hair and nails. Yeast mycoses regularly extend to the entire organ systems. Those areas of the skin in which humidity and warmth can accumulate on account of clothing, jewelry or shoes are affected p

40、articularly frequently. Athlete's foot represents one of the most familiar and widespread of these. Fungal diseases in the nail areas of the finger and foot are also particularly unpleasant. Moreover, super-infections of the skin by fungi and bacteria are not uncommon. If a primary infection is

41、extant, i.e. if a new infection occurs with a high number of microbes for one or several pathogens (for example staphylococcioften however nonpathogenic agentsfor example Candida albicans ), “super-infection” of the affected skin can occur if unfavorable influences coincide. The normal microflora of

42、 the skin (or another organ of the body) are overwhelmed by the secondary pathogens in this event. Depending on the microbe concernedsuch super-infections can be manifested in favorable cases as unpleasant skin appearances (itching, unattractive external appearance). In unfavorable cases, however, t

43、hey can lead to large-scale destruction of the skin, in the worst situation even the death of the patient. Such super-infections are observed for a wide variety of dermatological diseases, for example eczema, neurodermitis, acne, seborrheic dermatitis or psoriasis. Even many medical and therapeutic

44、measures, e.g. radiography or chemotherapy for tumor diseases, medicinally-induced immunosuppression caused as a side-effect or systemic treatment with antibiotics, as well as external chemical or physical influences (e.g. environmental pollution, smog), promote the occurrence of super-infections of

45、 the external and internal organs, in particular the skin and the mucous membrane. Although it is perfectly possible to fight super-infections with antibiotics, such substances usually have the disadvantage of unpleasant side effects. Patients are often allergic to penicillin for example, as result

46、of which a corresponding treatment would be ruled out in such cases. Moreover, topically administered antibiotics have the drawback of not only removing secondary pathogens from the skin, but also have an adverse effect on the purely physiological skin flora, with the result that the natural healing

47、 process is slowed down again. The aim of the present invention was to remedy the disadvantage of the prior art and provide substances and preparations containing such substances through the use of which super-infections an be cured, whereby the physiological skin flora does not suffer any significa

48、nt side effects. In contrast to the prokaryotic and eukaryotic cellular organisms, viruses represent biological structures which require a host cell for biosynthesis. Extracellular viruses (also referred to a “virions”) consist of a single or double stranded nucleic acid sequence (DNS or RNS) and a

49、protein mantle (called the capsid), sometimes surrounded by an additional envelope containing lipids. The entire structure comprising nucleic acid and capsid is referred to as the nucleocapsid. Viruses were originally classified according to traditional and clinical criteria, but nowadays they are g

50、enerally classified according to their structure, morphology and, in particular, the nucleic acid sequence. Medically important virus genera are typically influenza viruses (the Orthomyxoviridae family), Lyssaviruses (e.g. rabies, Rhabdovirus family), Enteroviruses (e.g. Hepatitis-A, Picornaviridae

51、family), Hepadnaviruses (Hepatitis-B, Hepadnavirus family). Virucides, i.e., substances capable of killing viruses do not actually exist in the strict sense of the term, as viruses do not have their own metabolism. Pharmacological interventions without damage to the cells that are not affected are,

52、however, difficult. Possible mechanisms of action in the fight against viruses are primarily the destruction of their replication, e.g., by blocking the enzymes in the host cell important for their replication. Furthermore, the release of viral nucleic acids into the host cell can also be prevented.

53、 Within the scope of the disclosure presented here, the terms “antiviral” or “effective against viruses”, “virucide” or similar refer to the property of a substance enabling it to protect a single or multi-cellular organism against the harmful effects of a viral infection, be it prophylactic or ther

54、apeutic, regardless of what the actual mechanism of action of the substance in individual cases is. Substances effective against viruses which do not damage the host organism, or do not do so to an unjustifiable degree, are absent in the prior art. A further aim of the present invention was therefor

55、e to find substances which effectively protect a single-celled or multi-cellular organism against the detrimental effects of a viral infection, be it prophylactic or therapeutic. Preservatives are antimicrobial substances which are added to a product (food and luxury items, pharmaceutical, cosmetic

56、or also chemical-technical preparations) during the production process in small amounts (usually between approx. 0.0005% and 1% active content, depending on the product). Preservatives are intended to protect products from contamination by microorganisms, in particular from detrimental changes cause

57、d by microbes, during production, storage and consumption. The following requirements are essentially demanded of a preservative: It must be sufficiently antimicrobial, as well as capable of being applied technically and safely in respect to health. The finished preparationthe commercial productmust

58、 also be harmless to health. Here it is necessary to consider that microorganisms, e.g., in cosmetic preparations, can be present primarily as a result of production or can enter the cosmetic preparation secondarily on account of the consumer. It must therefore be ensured that the finished product is also safe throughout the entire period of consumption. Preservatives authorized in food t
