Ceresinceresin[′se·rə·sən]Ceresina mixture of solid hydrocarbons, mainly alkylnaphthenes and alkanes; refined from ozokerite. Ceresin is similar to wax in its viscosity, density, color (from white to brown), and melting point (65°–88°C). The 1950’s saw the introduction of a means of ceresin production involving the use of petrolatum and paraffin deposits (“paraffin plugs”) formed in pipes used for the extraction and transfer of petroleum. Synthetic ceresin is produced by the catalytic synthesis of liquid fuel that consists mainly of normal alkanes and low-molecular-weight polyethylene. Ceresin is commonly used in the production of semisolid lubricants; it is also used as an anticorrosive coating for various mechanical devices and as an insulating material in electrical engineering. Like ozokerite, ceresin has medical uses. ceresincer·e·sin(ser'ĕ-sin),cer·e·sin, cerin , cerosin (serĕ-sin, -in, -ō-sin)Synonym(s): earth wax, mineral wax (1) . ceresin
