Definitions
- the present invention relates to the cleaning of hard surfaces.
- Hard surface cleaning compositions comprising a at least one one highly ethoxylated nonionic surfactant and possibly 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. It is thus an object of the present invention to provide hard surface cleaning compositions which can be effectively used in diluted form.
- 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.
- compositions comprising highly ethoxylated fatty alcohols are described in SU 595369 (abstract). These compositions are designed for the cleaning of metallic surfaces in weaving machines. Summary of the invention
- the present invention thus encompasses a composition for the cleaning of hard surfaces comprising from 0.5 % to 30 % by weight of the total composition of at least one nonionic surfactant, characterized in that said nonionic surfactant is of the formula RO-(CH 2 CH 2 O) n H wherein R is a C 8 to C 22 alkyl chain or a C 8 to C 28 alkyl benzene chain, and n is an integer of from 21 to 65, or mixtures thereof.
- the present invention also encompasses a composition for the cleaning of hard surfaces comprising from 0.5 % to 30 % by weight of the total composition of a mixture comprising at least one anionic surfactant and at least one nonionic surfactant, characterized in that said nonionic surfactant is of the formula RO-(CH 2 CH 2 O) n H wherein R is a C 8 to C 22 alkyl chain or a C 8 to C 28 alkyl benzene chain, and n is an integer of from 10 to 65, or mixtures thereof.
