NOVELTY - A composition comprises 30-90 wt.% water, 5-65 wt.% wax chosen from microcrystalline wax and paraffin wax, and 0.005-10 wt.% graphene. USE - Composition used for protecting chains from dirt of bicycle and motorbike e.g. terrain bike for riding in off-road environment (all claimed). ADVANTAGE - The composition provides chains of bicycle and motorbike, having excellent durability, desirable chain lengthening, and detrimental effects of dirt. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) protecting of bicycle or motorbike chain from dirt, which involves dripping the composition; (2) riding using mountain bike or motorbike with chain, which involves treating the chain with dirt protecting composition, and riding in an off-road environment; (3) preparation of composition, which involves preparing aqueous composition with water and wax and stirring in graphene; and (4) bicycle or motorbike chain covered by the composition.
