Physician's Materia Medica on Petrolatum
LANOLIN (Wool-fat)
The purified fat of the wool of sheep. As an ointment base it has the advantage over lard of greater chemical stability. A mixture of equal parts of Lanolin and Petrolatum is generally preferable to Lanolin alone.1

LARD
Either Lanolin or Lard may be used as an ointment base where absorption of the medicament is desired; petrolatum is much less readily absorbed, a fact to be borne in mind in selecting a vehicle for local medication.1

PETROLATUM
Mineral hydrocarbons. either liquid (Petrolina Oil), semi-solid Yasclin, Cosmolin, Soft Petrolatum) or of wax-like consistence (Paraffin Wax, Hard Petrolatum, ordinarily known as Parafiin). All are emollient and are used as vehicles for medicaments to be applied locally by spray, liniment, ointment or cerate. The mineral hydrocarbons are not absorbed as animal and vegetable fats are, but they do not necessarily prevent the absorption of the medicament as sociated with them.1
