CRESOL PREPARATIONS 457 



OLEUM GADINUM — OIL OF CADE 



Synamjms. Juniper Tar Oil, Oleum Juniperi Empyreumaticmn 



This is a tar obtained from the destructive distillation of Juni- 

 perus Oxycedrus, Linne, of the Mediterranean. It occurs as a thick 

 dark volatile oil of tarry odor and taste. Its action and uses are the 

 same as given for oil of tar, but it is often preferred to this agent 

 on account of its more agreeable odor. 



CRESOL PREPARATIONS 



There are three cresols, ortho, meta and para, all homologues of 

 phenol. They are obtained by the fractional distillation of coal tar. 

 Cresol, U. S. P., is- a mixture of the three, freed from phenol. It 

 occurs as a colorless or straw colored fluid, turning dark brown with 

 age or exposure to light. One mil dissolves in 50 mils of water ; it 

 is miscible with alcohol, ether, benzene or glycerin; soluble in solu- 

 tions of the fixed alkali hydroxides. It is often called " cresylic 

 acid." 



Preparations. 



Liquor Cresolis Compositus, a 50 per cent, solution in potash or 

 soda soap. This preparation is claimed to be twice as strong an anti- 

 septic as phenol. It is practically identical with Lysol and various 

 other soapy disinfectants.

Cresol 500 gms. 



Linseed Oil 300 gms. 



Potassium Hydroxide 80 gms. 



Alcohol 30 gms. 



Water, enough to make. . .,.1000 gms. 



OTHER CRESOL PREPARATIONS 



* Tricresol is a mixture of cresols : ortho cresol 35 per cent., meta 

 cresol 40 per cent, and para cresol 35 per cent. 



* Creolin is an emulsion of cresol made by the use of a resin soap. 

 It occurs as a dark brown liquid, of characteristic odor. When 

 diluted with water it makes an opaque or milky liquid. There are 

 many cresol preparations similar to creolin and used interchangeably 

 with it. In general they are less toxic than phenol but should be 

 used with care upon dogs and coats. Merck's Creolin ( Creolin Pear- 

 son) is probably the best for internal use and is the least toxic, al- 

 though many other similar preparations have been used without 

 causing trouble in horses and cattle.
