A liquid saliva replacement formulation comprises an aqueous solution of carboxymethylcellulose having a viscosity in the range 170-230 centipoise, a preservative which consists either of a mixture of methyl, ethyl and propyl p-hydroxybenzoate or 2-bromo-2-nitropropane 1,3-diol and a mixture of salts present in normal saliva in a buffer medium which is sufficient to maintain the formulation at a pH in the range 5.8-6.2. The formulation is especially suitable for delivery to the mouth via an atomiser. |
