Liquid  paraffin  as  an  excipient  for  hypodermic  injections. — Dr. 
Mennier-Lyon  has  discovered  that  several  substances  which,  owing  to 
their  irritating  properties,  could  not  be  used  hypodermically,  lose  this 
disagreeable  property  when  dissolved  in  liquid  paraffin,  which  to  be 
suitable  for  hypodermic  use  must  be  neutral  to  litmus-paper ;  heated 
to  180°C.  no  vapors  should  be  evolved,  sp.  gr.  at  150°C.=0'870 — 
0*895  ;  it  should  be  odorless  and  tasteless.  If  corresponding  with  the 
aforesaid  properties  a  slight  fluorescence  does  not  impair  its  efficacy^ 
although  the  German  pharmacopoeia  condemns  it.  Liquid  paraffin 
dissolves  only  a  limited  number  of  oxygenated  compounds,  but  readily 
dissolves  hydrocarbons,  ether,  chloroform,  fats  and  fatty  oils ;  men- 
thol, thymol,  terpinol,  etc.,  are  soluble  in  all  proportions.  Large 
quantities  of  iodine,  bromine,  phosphorus  and  iodoform  are  also  solu- 
ble in  liquid  paraffin.  According  to  Bocquillon,  it  dissolves  four 
times  its  volume  of  sulphuretted  hydrogen  gas,  i.  e.,  more  than  water 
is  capable  of  dissolving.  Oil  of  eucalyptus  produces  abscesses  when 
injected  subcutaneously,  hence  eucalyptol — (so-called  absolute  eucalyp- 
tol  obtained  by  distilling  oil  of  eucalyptus  at  a  temperature  of  170° — 
180°C.)  only  should  be  used.  One  part  of  eucalyptol  is  mixed  with 
4  parts  of  liquid  paraffin.  5  grams  of  this  mixture  are  injected  twice 
daily.  The  same  proportions  are  used  for  myrtol.  For  iodoform 
the  following  method  is  used  :  1  gram  of  iodoform  is  dissolved  in  20 
grams  of  eucalyptol  and  100  grams  of  liquid  paraffin.  Of  this  mix- 
ture 5  grams  are  injected  twice  daily.  Carbon  bisulphide  2  to  100  of 
paraffin  oil  is  used  in  same  doses. 
Liquid  paraffin  will  not  dissolve  water,  strong  or  diluted  alcohol, 
glycerin,  methylic  alcohol,  amylic  alcohol,  salicylic  acid,  salts  of 
mercury,  terpin,  chloral,  naphthol,  alkaloids,  glucosides  and  iodol.  It 
dissolves  but  a  small  quantity  of  carbolic  acid. — Ph.  Post.  xx,page  207.
