Definitions
- the present invention relates to the cleaning of hard surfaces.
- Hard surface cleaning compositions comprising at least one one highly ethoxylated nonionic surfactant and an anionic surfactant, are diluted before use, exhibiting outstanding dilute cleaning performance.
- Hard surface cleaning compositions are well known in the art. It is known to use various surfactants in these compositions, including ethoxylated nonionic surfactants. Ethoxylated nonionic surfactants which are typically used in such compositions are lower ethoxylates, i.e. with a degree of ethoxylation of 5 to 7.
- compositions which can be used in diluted form are also known in the art.
- the technical problem lies in sustaining upon dilution an efficient cleaning performance.
- Such compositions for dilute cleaning are described for instance in copending European Patent Application EP 91870109.5.
- the dilute cleaning performance is obtained by using alkanolamines.
- hard surface cleaning compositions comprising at least one highly ethoxylated nonionic surfactant, preferably with at least one anionic surfactant.
- These compositions unexpectedly exhibit outstanding cleaning performance upon dilution, compared to the same compositions without said nonionic surfactant while the cleaning performance of the neat, i.e. undiluted compositions is similar, regardless of the presence of said nonionic surfactant.
- hard surface cleaning compositions comprising said highly ethoxylated nonionic surfactant exhibit outstanding cleaning performance when used both neat and diluted.
- compositions comprise a highly ethoxylated nonionic surfactant, yet they are especially effective on greasy soils.
- greasy soils are commonly brought by cooking with oils and fatty foods, and by simple contact with human skin, thus they are present on most surfaces, particularly in bathrooms and kitchens.
- the compositions according to the present invention are suitable for use on all such surfaces.
- This invention is also particularly useful as it allows to formulate compositions with reduced levels of other ingredients, which yet retain optimal cleaning performance, due to said highly ethoxylated nonionic surfactant; also, the user needs less product to achieve the same task. This advantage is particularly valuable in terms of environmental compatibility.
