Cerates are unctuous substances of such consistency that they may be easily spread, at ordinary temperature, upon muslin, or similar material, with a spatula, and yet not so soft as to liquefy and run when applied to the skin. They are not often prescribed.

The following three cerates are official:-

Ceratum

See Cera Flava.

Ceratum Cantharidis

See Cantharis.

Ceratum Resinae

See Terebinthina.
