摘要：
The invention provides an oral care composition obtainable by: (i) preparing an oil-in-water emulsion by dispersing an oil phase into an aqueous continuous phase, the aqueous continuous phase comprising an oil-in-water emulsifier which is selected from one or more hydrophobins, so that emulsified particles of oil phase are formed which are emulsified with the one or more hydrophobins and (ii) combining the emulsion so obtained with an oral care base formulation which is suitable for treating the surfaces of the oral cavity. Compositions of the invention demonstrate enhanced deposition of oil phase components onto oral cavity surfaces such as tooth enamel and tooth dentine, and in particular onto damaged surfaces such as scratched and demineralised enamel.
