DESCRIPTION:
BRIEF SUMMARY
The invention concerns a washing and cleaning agent with antimycetic action.
Mycoses belong to the modern diseases of civilisation in the highly industrialised countries. According to recent estimates, every third citizen suffers from a skin or mucous membrane mycosis one or more times in the course of his life. Pharmaceuticals, such as antibiotics, cytostatics, contraceptives and immunosuppressives, favour the multiplication of fungi on the skin and mucous membranes of human. Other environmental influences, such as cosmetics and cigarette consumption, also contribute to a multiplication of fungi. Due to the keeping of domestic animals, especially house and amusement animals in large towns, the development of fungi in the immediate surroundings of humans is also favoured. Admittedly, effective medicaments are today available for the treatment of this type of fungal diseases but recidivation frequently occurs. This is due to the fact that admittedly the fungi and fungal spores are destroyed on the skin and the mucous membranes but the fungi in the human environment resist external influences and do not die off. Fungal spores in particular are very resistant and can, therefore, survive environmental influences harmful for other organisms.
Thus, with the known washing and cleaning agents, it is not possible to kill off fungi and fungal spores since fungi and especially their spores are often resistant to tensides.
A special problem arises from this that, on the one hand, many articles of clothing consist of materials which only permit a washing at low temperatures and, on the other hand, cleaning and rinsing agents can only be used at low temperatures.
Thus, it was the task of the invention to find an agent with which fungi and fungal spores in laundry and in human surroundings can also be killed off at temperatures below 100.degree. C. This task was solved by a washing and cleaning agent with antimycetic action which is characterised in that, besides the usual component materials, it contains sodium lauryl sulphate and imazalil.
Conventional washing agents cannot completely kill off fungi and fungal spores at temperatures below 100.degree. C. Surprisingly, it was not found that, by the addition of two synergistically-active active materials, the killing off of fungi and fungal spores is possible at lower temperatures, even below 60.degree. C.
The washing and cleaning agent according to the invention is suitable also for killing off fungi and fungal spores on articles of clothing which cannot be boiled but can only be washed at 30.degree. C. or 60.degree. C. Furthermore, this agent is suitable for destroying fungi and fungal spores on articles in the case of cleaning.
For the killing off of the fungi and fungal spores, the agent should contain up to 40% sodium lauryl sulphate and up to 0.5% imazalil. By imazalil there is understood 1-[2-(2,4-dichlorophenyl)-2-(2-propenoxy)ethyl]-1H-imidazole.
Preferably, there is used an amount of 10 to 30% sodium lauryl sulphate. The fungicide imazalil is, due to the synergistic combination with sodium lauryl sulphate, only necessary in small amounts of up to 0.5%. An amount of 0.02 to 0.2% has been shown to be suitable in order still to ensure a 100% killing off of the fungi and fungal spores.
The ratio of sodium lauryl sulphate to imazalil is not critical. However, it has been shown that a ratio of sodium lauryl sulphate to imazalil of 1000:1 is still suitable to kill off 100% of the fungi and fungal spores. In the case of a ratio of 100:1, the solution furthermore still manifests a bactericidal action in the case of a germ content of 10 to 50 germs per ml. of liquor.
The agent according to the invention is suitable for use as washing agent, as cleaning agent and as rinsing agent. The special properties of the agent according to the invention make it possible to use this agent as washing agent for laundry at low temperatures. The killing off of micro-organsims and fungi in boiled laundry is no problem since these organisms are not able to survive boiling temperatures. Howe
