Abstract
A concrete release agent, particularly on the basis of mineral oil without solvent, mineral oil with solvent, emulsions, or ester oil, contains nanoparticles that have a photocatalytic effect on organic molecules of the release agent, particularly also such mineral-modified photocatalysts having broader absorption spectra that also act in visible light, in an amount that brings about the result that the organic components of the release agent are photocatalytically decomposed by the effect of daylight after the form/mold has been removed from the concrete. In this connection, the organic components are removed from the concrete surface via the formation of volatile reaction substances.
