摘要：
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 2.5% by weight of phosphate source (by weight based on the total weight of the second composition)； in which the second composition is stored separately from the first composition prior to usage of the product in a manner to avoid contact between the water in the second composition and the agent for the remineralisation of teeth in the first composition； and also in which the first and second compositions are adapted to be admixed and applied to the surface of the teeth for sustained contact.
