L .
parum too little affinis akin .
So named in allusion to its chemical inactivity .] (
Chem .)
A white waxy substance ,
resembling spermaceti ,
tasteless and odorless ,
and obtained from coal tar ,
wood tar ,
petroleum ,
etc .,
by distillation .
It is used in candles ,
as a sealing agent (
such as in canning of preserves ),
as a waterproofing agent ,
as an illuminant and as a lubricant .
It is very inert ,
not being acted upon by most of the strong chemical reagents .
It was formerly regarded as a definite compound ,
but is now known to be a complex mixture of several higher hydrocarbons of the methane or marsh -
gas series ;
hence ,
by extension ,
any substance ,
whether solid ,
liquid ,
or gaseous ,
of the same chemical series ;
thus gasoline ,
coal gas and kerosene consist largely of paraffins .

but in commerce it is commonly spelled paraffine .
