The present invention relates to nanoparticle based sand conditioner composition and a method of synthesizing the same. The composition has the raw material compound RM 1, RM 2, RM 3 and RM 4. The RM1 has carbonaceous material, hydrocarbons, ultrafine metal/metal oxide and ceramic oxide nanoparticles and metallic wires. The RM 2 has natural carbon source. The RM 3 comprises synthetic/non-renewable carbon source. The RM 4 has hydrocarbons. The method of synthesizing nanoparticle based sand conditioner comprises mixing RM 2 and RM 4 in a mixer for 10 minutes for coating RM 2 with RM 4 to obtain an intermediate product. The RM 1 and RM 3 are added to an intermediate product in a mixer and mixed for 10 minutes to get a uniform/homogeneous mixture which is cooled to obtain a sand conditioner composition impregnated with nanoparticles into carbon.
