BRIEF SUMMARY
DESCRIPTION
This invention relates to a cleaning liquid, which is particularly intended for use in emergency sets, and its use as a general cleaning agent, as an agent for cleaning and/or decontaminating skin in the case of injuries and/or contaminations of human beings and animals and for a medical treatment of and for cleaning skin.
A large number of cleaning liquids are known, also for medical purposes. When they are used in the household or for medical purposes, they contain water as a main constituent, as a rule, to which various detergents have been added. For technical purposes, aqueous solvents are not yet regularly used as cleaning liquids although aqueous cleaning liquids are increasingly employed for ecological reasons.
As a rule, all said cleaning liquids have a defined composition, which render them particularly suitable For certain purposes. The composition also determines the limits of the application. For instance, aqueous cleaning liquids cannot be used, as a rule, at temperatures which are distinctly below the freezing point. On the other hand, it is not permissible to use highly volatile solvents in tropical regions. Owing to said restrictions a suitable cleaning agent is often not available in an emergency, e.g., in case of an accident or when an important part of a plant has been soiled or contamination with malodorous, soiling, toxic or etching substances has been effected. In such cases there is a demand for a cleaning agent which is of universal utility and is always ready at hand in a set or in a tear strip package. Such a cleaning agent should be usable in combination with and without water and after use should be suitable for being readily disposed of with the waste water or domestic refuse.
That object is accomplished in accordance with the invention by the provision of a cleaning liquid which contains as components (A) a polyalkyleneglycol monoalkyl ether and (B) a polyalkyleneglycol fatty acid partial glyceride and optionally at least one non-ionogenic liquid surface-active agent.
The cleaning liquid according to the invention is particularly suitable for use in emergencies. It may be used, e.g., as an agent for cleaning and/or decontaminating skin in the case of injuries and/or contaminations of human beings and animals. But it may also be used to clean and/or decontaminate surfaces, e.g., of machines, glass panes, furniture, plants, etc, and there are no special restrictions.
Whereas the cleaning liquid in accordance with the invention may be used or mixed with water it can preferably be applied without water or independently of water and in that case will have a quite comparable soil-removing cleaning or cleaning activity. It may be used to remove contaminating chemicals and will have also a certain detoxicating activity. It is substantially non-toxic and non-flammable and has a low volatility and will preserve its full utility at low temperatures far below the freezing point as well as at tropical temperatures. As a surface-cleaning agent it may replace conventional cleaners, such as gasoline, aromatic compounds, turpentine, alcohol, chlorinated hydrocarbons or ethers and esters.
The components A to D which are employed are commercially available substances, which are offered in the market for various purposes. Components C and D may be described as surface-active agents or surfactants, which have lipophilic and hydrophilic properties and are soluble in or compatible with water. But the components C and D may be replaced by conventional non-ionogenic surface-active agents, which individually or in combination have lipophilic and hydrophilic properties. It will be understood that components C and D may also be used in combination with further non-ionogenic surface-active agents. The non-ionogenic surface-active agents which have a conventional structure and those which have the structural formulas C and D may be soluble or insoluble in water. But it is important that the lipophilic and hydrophilic properties are balanced so that the cleaning liquid in accordance with the i
