Abstract: The present invention is directed to aqueous compositions with wax and graphene. These compositions offer surprising benefits in reducing bicycle or motorbike chain lengthening, particularly in off road environments with high dirt and water levels such as during mountain biking or off-road biking. The invention is further directed to a method of preparing such compositions and to the use of such compositions on bicycle or motorbike chains.
