Naphthalene sulfonic acid/formaldehyde condensates may be used (i) in a liquid multiphase cleaning composition with at least two continuous phases which contains at least one aqueous phase I and a non-aqueous liquid phase II immiscible with this aqueous phase and which can be temporarily converted into an emulsion by shaking, (ii) in a composition for cleaning hard surfaces to reduce the rain effect and/or the film effect, (iii) in a process for reducing the rain effect and/or the film effect on a hard surface treated with a liquid cleaning composition, the surface being treated with a liquid cleaning composition in concentrated or diluted form containing at least one naphthalene sulfonic acid/formaldehyde condensate and (iv) in a process for cleaning hard surfaces, more particularly glass, in which a cleaning composition according to (i) is temporarily converted into an emulsion by shaking, applied to the surface to be cleaned, preferably by spraying, in quantities of 1.5 to 10 g per m and the surface is then optionally cleaned by wiping with a soft absorbent material.

Lignin sulfonates may be used (i) in a liquid multiphase cleaning composition with at least two continuous phases which contains at least one aqueous phase I and a non-aqueous liquid phase II immiscible with this aqueous phase and which can be temporarily converted into an emulsion by shaking, (ii) in a composition for cleaning hard surfaces to reduce the rain effect and/or the film effect and (iii) in a process for reducing the rain effect and/or the film effect on a hard surface treated with a liquid cleaning composition, the surface being treated with a liquid cleaning composition in concentrated or diluted form containing at least one lignin sulfonate and (iv) in a process for cleaning hard surfaces, more particularly glass, in which a cleaning composition according to (i) is temporarily converted into an emulsion by shaking, applied to the surface to be cleaned, preferably by spraying, in quantities of 1.5 to 10 g per m,and the surface is then optionally cleaned by wiping with a soft absorbent material.

Multiphase cleaning composition containing lignin sulfonate

Naphthalene sulfonic acid/formaldehyde condensates (i) may be used in a composition for cleaning hard surfaces to reduce the rain effect and/or the film effect, (ii) may be present in a cleaning composition for hard surfaces in combination with one or more other anionic and/or nonionic surfactants and (iii) may be used in a process for reducing the rain effect and/or the film effect on a hard surface treated with a liquid cleaning composition, the surface being treated with a liquid cleaning composition in concentrated or diluted form containing one or more naphthalene sulfonic acid/formaldehyde condensates.
