A dental cream having desirable rheological characteristics such as smoothness, good "stand-up" on a toothbrush and absence of "tailing", contains a mixture of sodium carboxymethyl cellulose and a low viscosity hydroxyethyl cellulose, as a gelling agent, these compounds being present in a weight ratio of about 3:2 to 2:3 to each other. The dental cream may also contain fluorides such as sodium monofluorophosphate optionally together with sodium fluoride, and calcium phosphate as a polishing agent. Alternatively, the gelling agent may be high viscosity hydroxyethyl cellulose alone (i.e. without any in which case sodium carboxymethyl cellulose. |
