Calamine, zinc oxide and bentonite was triturated with a solution of sodium citrate.

Liquefied phenol, glycerine and sufficient purified water was added to produce 1000 ml.


Calamine is zinc oxide with small amount of ferric oxide. Both are indiffusible solids, so bentonite is added as thickening agent which causes flocculation of calamine. However the preparation becomes viscous and is difficult to pour from bottle. Sodium citrate is added to cause partial deflocculation of calamine and makes preparation pourable. Liquefied phenol is used as preservative and glycerol is used as emollient.
