Paraffin wax

is a type of petroleum wax that is naturally derived from decayed organic matter. It is a combination of a long series of hydrocarbons. Generally, paraffin wax is non-toxic in its normal state. However, when it is burned, paraffin wax produces fumes that may result in physical discomfort and nausea.

Alkanes

are saturated hydrocarbons containing a carbon chain, with each carbon atom bonded to hydrogen atoms. Shorter carbon chains form compounds that are liquid at room temperature, while longer chains produce compounds that are in the solid state.
