Gepost op: 29 mars 2026What is the correct formula for Zinc liniment, considering the traditional composition of 60 g zinc oxide, 700 mg oleic acid (potentially replaced by Arlacel C if unavailable), and 39.3 g groundnut oil with sieved zinc oxide, or the alternative NF lime oil liniment consisting of 10 g zinc oxide, 5 g borax, and 42.5 g each of cod liver oil and lime water for dermatological use?
Answer
Gepost op: 29 mars 2026Composition of Zinc Oxide Liniment
A possible composition for zinc oxide liniment is as follows: 60 g zinc oxide (ZnO), 700 mg oleic acid, and 39.3 g peanut oil. Since oleic acid may no longer be available, it can be replaced by Arlacel C. It is important that the zinc oxide is sieved before use.
Alternative Formulation
An alternative from the National Formulary (NF) is lime oil liniment with zinc oxide and borax. This preparation contains the following components:
- Zinc oxide: 10 g
- Borax: 5 g
- Cod liver oil and lime water: equal parts up to 42.5 g
