The invention relates to a detergent for gentle removal of inks as used for marking in a roll mill, and to markers as used in production for temporary marking. According to the invention, the problem is solved by a detergent which permits the gentle removal of inks or markers from metallic surfaces in the form of a concentrate or a cleaning bath solution containing at least one water-immiscible solvent in an amount of 4 to 200 g/l, at least one anionic and/or nonionic surfactant in an amount of 8-300 g/l, at least one complexing agent in an amount of 1-100 g/l, at least one buffer substance in an amount of 1-100 g/l and at least one water-miscible solvent in an amount of 4-200 g/l in water.

Detergent for gentle removal of inks and markers

The invention relates to fissure-detection agents for fault detection according to the penetration method of metallic and/or non-metallic components, which are a microemulsion comprising at least 10 wt. % of water A), at least 0.1 wt. % of at least one dye B), at least 5 wt. % of at least one substantially water-insoluble liquid phase C) and at least 2 wt. % of at least one surfactant D) selected from non-ionic, anionic and/or amphoteric surfactants, the sum of all constituents being 100 wt. %, wherein the fissure-detection agent has a mean particle size in the range of 1 to 250 nm and a transparency of at least 70% at 600 nm. The invention also relates to the production of said fissure-detection agents, to a process for their preparation or/and disposal, and their use.
