Abstract: The invention provides an oral care product suitable for the remineralisation of teeth, the product comprising: (i) a first composition having a non-aqueous liquid continuous phase including a thickening agent, a humectant, and an agent for the remineralisation of teeth; the agent for the remineralisation of teeth being a mixture of a calcium source and a phosphate source which, when delivered to the teeth results in the in situ generation of hydroxyapatite on teeth; (ii) a second composition having an aqueous liquid continuous phase including a thickening agent and a humectant, the second composition comprising at least 30% by weight water (by weight based on the total weight of the second composition), and less than 2.

Abstract: The invention provides an oral care composition suitable for delivering a temporary whitening effect to the surface of teeth, the composition comprising: a continuous phase comprising water or polyhydric alcohol or a mixture thereof; a tooth surface whitening agent which is dispersed in the continuous phase, and a deposition aid for the tooth surface whitening agent; characterized in that the tooth surface whitening agent is a pearlescent pigment in an amount of at least 0.1% by weight based on the total weight of the composition, the pearlescent pigment being formed by coating one or more metal oxide layers onto particles of an inorganic substrate.

Abstract: An Oral care product is provided which includes a mesoporous calcium silicate biomaterial (MCSB) dispersed in a polymeric material matrix. MCSB is an insoluble composite material of calcium oxide-silica.
