The invention relates to compositions containing a) one or more substances selected from the group of hydrogen peroxide and substances releasing hydrogen peroxide, b) water, d) one or more substances selected from the group consisting of hydroxypyridones and the salts thereof, characterized in that said compositions do not comprise polymers having thickening properties. The compositions are particularly characterized by the advantageous storage stability thereof. The invention relates to compositions containing a) one or more substances selected from the group of hydrogen peroxide and substances releasing hydrogen peroxide, b) water, d) one or more substances selected from the group consisting of hydroxypyridones and the salts thereof, characterized in that said compositions do not comprise polymers having thickening properties. The compositions are particularly characterized by the advantageous storage stability thereof. The invention relates to a method for operating a drive apparatus (1) of a vehicle (2), which drive device comprises at least one internal combustion engine (3) and at least one electric machine (4) for generating a common torque, wherein the electric machine (4) can be uncoupled and coupled as desired, comprising the following steps: - determining a first power (E1) which is expected to be required in order to drag the electric machine (4) by means of the internal combustion engine (3), - determining a second power (E2) which is expected to be required to uncouple and subsequently couple the electric machine (4), - comparing the first power (EÂ1Â) with the second power (E2), wherein the electric machine (4) is uncoupled only when the second power (E2) is less than the first power (E1). Furthermore, the invention relates to a device for operating a drive apparatus of a vehicle. In addition, the invention relates to a computer program product.La invención se relaciona con composiciones que contienen a) una o más sustancias seleccionadas del grupo
