Definitions

• the present invention relates to compositions for cleaning hard-surfaces, especially in-house hard-surfaces.
• compositions for cleaning hard-surfaces have been disclosed in the art. Much of the focus for such compositions has been on providing outstanding cleaning on a variety of surfaces and soils. For some specialised cleaners, such as glass cleaners, much effort has additionally been devoted to the formulation of so-called "streak-free" products, i.e. products which leave no or little visible residues after use.
• the object of the present invention is to formulate hard-surface cleaning compositions which clean and provide gloss to the cleaned surface. That is different from a "streak-free" composition, in that gloss additionally requires improved reflectance of light from the cleaned surface.
