Definitions
- the present invention relates to cosmetic drug combinations and preparations containing such drug combinations, as well as their use as effective against bacteria, mycota and viruses substances.
- the healthy warm-blooded organism especially the healthy human skin, is populated with a variety of non-pathogenic microorganisms.
- This so-called microflora of the skin is not only harmless, it represents an important protection against opportunistic or pathogenic germs.
- Bacteria belong to the prokaryotic unicellular organisms. They can be roughly distinguished according to their shape (sphere, cylinder, curved cylinder) and the structure of their cell wall (gram-positive, gram-negative). Finer subdivisions also take into account the physiology of the organisms. There are aerobic, anaerobic and facultatively anaerobic bacteria. Some individuals are of medical importance in their capacity as pathogenic agents, while others are completely harmless.
- Antibiotics for example, which is not applicable to all antimicrobial substances, can be dated to the year 1941, although the first findings on penicillin were already found in 1929. Antibiotics in the modern sense are not for all medical, even not suitable for cosmetic applications because Often the warm-blooded organism, for example the sick patient, is impaired in its use in some way in its metabolic functions.
- Gram-negative bacteria are, for example, Escherichia coli, Pseudomonas species and Enterobacteriaceae, such as Citrobacter.
- Gram-positive bacteria also play a role in cosmetics and dermatology.
- bacterial secondary infections are of etiological significance, among other influences.
- One of the most important microorganisms associated with impure skin is Propionibacterium acnes.
- Impure skin and / or comedones affect the well-being of those affected but even in mild cases. Since virtually every adolescent or person is affected by blemished skin of some kind, many people need to remedy this condition.
- a particular object of the present invention was therefore to find a substance or combination of substances which is effective against impure skin or Propionibacterium acnes.
- the present invention relates in a further embodiment cosmetic deodorants.
- Such formulations serve to eliminate body odor, which arises when the per se odorless fresh sweat is decomposed by especially gram-positive microorganisms.
- the usual cosmetic deodorants are based on different active principles.
- liquid deodorants for example aerosol sprays, roll-ons and the like, as well as solid preparations, for example deodorant sticks ("sticks"), powders, powder sprays, intimate cleaners, etc.
- antiperspirants can be prevented by astringents - mainly aluminum salts such as aluminum hydroxychloride (Aluchlorhydrat) - the formation of sweat.
- Aluchlorhydrat aluminum hydroxychloride
- the bacterial flora on the skin can be reduced. Ideally, only the odor causing microorganisms should be effectively reduced. In practice, however, it has been found that the entire microflora of the skin can be affected. The sweat flow itself is not influenced by this, ideally only the microbial decomposition of the sweat is temporarily stopped.
- body odor can also be masked by fragrances, a method that is least in line with the consumer's aesthetic needs, as the mixture of body odor and perfume smells rather unpleasant.
- Another object of the present invention was therefore to develop cosmetic deodorants which do not have the disadvantages of the prior art.
- the deodorants should protect the microflora of the skin largely, but selectively reduce the number of microorganisms that are responsible for the body odor.
- a further object was to develop cosmetic deodorants which harmonize with the widest possible variety of customary cosmetic auxiliaries and additives, in particular with the perfume ingredients which are especially important in deodorizing or antiperspirant formulations.
- Yet another object of the invention was to provide cosmetic deodorants which are effective over a prolonged period, on the order of at least half a day, without noticeably reducing their effect.
- Eucaryotes are organisms whose cells (Eucytes), unlike those of the so-called procaryotes (Procytes), have a nucleus delimited by the nuclear envelope and the nuclear membrane from the rest of the cytoplasm. The nucleus contains the genetic information stored in chromosomes.
- mycobionts include, for example, yeasts (Protoascomycetes), molds (Plectomycetes), mildew (Pyrenomycetes), downy mildew (Phycomycetes), and wild mushrooms (Basidiomycetes).
- Fungi are not plant organisms, but like these they have a cell wall, cell-filled vacuoles, and a microscopically visible plasma flow. They contain no photosynthetic pigments and are C heterotrophic. They grow under aerobic conditions and gain energy through oxidation of organic substances. However, some representatives, such as yeasts, are facultative anaerobes and capable of producing energy through fermentation processes.
- Dermatomycoses are diseases in which certain types of fungi, in particular dermatophytes, invade the skin and hair follicles.
- the symptoms of dermatomycoses include blisters, exfoliation, rhagades and erosion, usually associated with itching or allergic eczema.
- Dermatomycoses can be subdivided essentially into the following four groups: dermatophytes (eg, epidermophytia, favus, microsporia, trichophytia), yeast mycoses (eg, pityriasis and other pityrosporum-related mycoses, candidal infections, blastomycosis, Busch-Buske disease, torulosis, Piedra alba, torulopsidosis, tricho- sporosis), mold mycoses (eg aspergillosis, cephalosporidosis, phycomycosis and scopular isopidemosis), systemic mycoses (eg chromomycose, coccidiomycosis, histoplasmosis).
- dermatophytes eg, epidermophytia, favus, microsporia, trichophytia
- yeast mycoses eg, pityrias
- the pathogenic and facultative pathogens include, for example, Candida species (for example Candida albicans) and those of the family Pityrosporum from the group of yeasts.
- the involvement of Pityrosporum ovale in the development of psoriasis is discussed by experts.
- An object of the present invention was to obviate the drawbacks of the prior art and to provide substances and preparations containing such substances, by the use of which the formation of dandruff is prevented, the physiological skin flora not suffering any significant losses.
- topically administered antibiotics have the disadvantage that they not only rid the skin flora of the secondary pathogen, but also severely impair the physiological skin flora and the natural healing process is slowed down in this way again.
- the object of the present invention was to eliminate the disadvantages of the prior art and to provide substances and preparations containing such substances, by the use of which superinfections can be cured, wherein the physiological skin flora suffers no appreciable losses.
- Protozoa are parasitically living unicellular organisms with clearly delineated nucleus that reproduce asexually (by dividing into two or four divisions and budding) or sexually (gameto-, gamonto- and autogamy).
- the food intake from the environment takes place by permeation and by Pino- or phagocytosis.
- motile state forms in addition to vegetative, mostly motile state forms (so-called trophozoites), most protozoa can also form cysts as permanent forms under unfavorable circumstances.
- protozoa are subdivided into four different groups:
- Parasitic protozoa are often transmitted in subtropical and tropical areas by stinging and sucking insects, but also by dirt and smear infection and through the food chain.
- Some medically and dermatologically relevant protozoonoses are: trichomoniasis (caused by Trichomonas vaginalis), Lamblia (caused by Lamblia intestinalis), visceral and cutaneous and mucosal leishmaniasis (caused for example by Leishmania donovanii, L. tropica, L. braasiliensis, L mexicana, L. diffusa or L.
- trypanosmiasis caused by various species of trypanosomes
- amoebic dysentery and amebiasis caused, for example, by various Entamoeba species, Jodamoeba butschlii or Naegleria fowleri
- coccidosis by Isospora belli
- Balantidenruhr caused by Balantidium coli
- Protozoan-induced medical and dermatological phenomena affect, in some cases substantially, human well-being. There is therefore a significant need for the persons concerned to remedy this situation.
- An object of the present invention was thus to find active principles against protozoa.
- viruses In contrast to the prokaryotic and eukaryotic cellular organisms, viruses [lat. Poison] are biological structures that require a host cell for biosynthesis. Extracellular viruses (also called “virions”) consist of a single-stranded or double-stranded nucleic acid sequence (DNA or RNA) and a protein coat (called capsid), optionally surrounded by an additional lipid-containing envelope (Envelope). The classification of viruses was classed according to clinical criteria, but nowadays mostly according to their structure, their morphology, but in particular according to the nucleic acid sequence.
- influenza viruses family of Orthomyxoviridae
- lyssaviruses e.g., rabies, family of rhabdoviruses
- enteroviruses e.g., hepatitis A, family Picornaviridae
- hepadnaviruses e.g., hepatitis B, family Hepadnaviridae
- Viruzide ie virus killing substances in the true sense does not exist because viruses do not have their own metabolism. It was therefore also discussed whether viruses should be classified as living things. At any rate, pharmacological interventions without damaging the unaffected cells are difficult. Possible mechanisms of action in the fight against the viruses are primarily the disruption of their replication, for example by blocking the enzymes which are important for replication and which are present in the host cell. Furthermore, the release of the viral nucleic acids into the host cell can be prevented.
- antiviral or “effective against viruses”, “virucidal” or the like understood the property of a substance to protect a single or multicellular organism, whether prophylactically or therapeutically, from harmful consequences of a viral infection, regardless of what actual mechanism of action of the substance in an individual case is.
- preservatives are, for example, the compounds known as parabens, in particular 4-hydroxybenzoic acid and its esters, methylparaben, ethylparaben, propylparaben, isopropylparaben, butylparaben, isobutylparaben, phenylparaben.
- Hydroxamic acids are a class of chemical compounds containing the grouping -CO-NHOH as a functional group.
