[0059] Tests for paint compatibility of compositions

[0060] Table 1 shows the constituents and test paints of the respective compositions (e.g. = examples according to the invention; c.e.g. = comparative examples) and the results. In this case, the numerical information is in each case % by weight, based on the total weight of the composition concerned. In this case, the compositions are specified in the tables in the undiluted state. The relevant compositions in the table were used in the tests at 50% (v / v) dilutions with demineralized water.

[0061] The tests were each carried out based on the paint compatibility test VW TL 52164, 6.6 developed by DEKRA. Here, a panel comprising a homogeneous lacquer (blue; VW's turquoise: VW Y5L) and an additional varnish Imola Red II (red; BMW) was used in each case. The painted panels were each coated with the relevant test composition and, after a contact time of 10 minutes, the panels were dried at 100° C. for 1 hour. The surface...

Abstract

The invention relates to an alcohol composition, which can be used as a windscreen washing liquid for motor vehicles in winter. The windscreen washing liquid comprises an anionic surfactant, in particular C12-C14 olefin sulfate with C3-C10 ethylene oxide (EO), and a nonionic surfactant. The invention also relates to an application of the composition on cleaning and / or defrosting the windows of vehicles, in particular glass windows, such as glass windscreens of motor vehicles; and a corresponding method of using the windscreen washing liquid to clean / defrost the windows.

Description

technical field [0001] The present invention relates to an alcohol composition which can be used as a winter windshield washer fluid in motor vehicles and which comprises anionic surfactants, especially C with 3 to 10 ethylene oxide units (EO). 12-14 olefin sulfates) and nonionic surfactants. The invention also relates to the use of the composition for cleaning and / or defrosting a vehicle window, in particular a glass window, such as glass used as a windshield in a motor vehicle window; and to a corresponding method for cleaning and / or defrosting such a window. Background technique [0002] Compositions that can be used as winter windscreen washer fluids for cleaning and defrosting are known and commercially available. However, said compositions often contain standard surfactants, which are often incompatible with painted surfaces, especially automotive paints, and / or whose cleaning performance is insufficient. For example, using olefin sulfates as standard surfactants, t...
