<p>An aerosol dentifrice formulation is provided comprising a high water based system, a specific particle size abrasive and a liquefied gas propellant, characterised in that the liquefied gas comprises 2-8 wt% of a non-hydrocarbon and 2-6 wt% of a hydrocarbon propellant. There is provided a dentifrice formulation comprising a fluid mixture which includes a liquefied gas propellant and containing a particulate abrasive, characterised in that the particulate abrasive comprises 1-10% by weight of the mixture, has a particle size in the range 5-40 microns and comprises a combination of a more hard and a less hard abrasive. Another aspect of the invention provides for an aerosol dentifrice comprising water , a particulate abrasive and a liquefied gas propellant, characterised in that the propellant comprises 2-8 wt% of a non-hydrocarbon and 2-6 wt% of a liquefied hydrocarbon propellant, the particulate abrasive comprising 1-10% by weight of the mixture, has a particle size in the range 5-40 microns and comprises a combination of a more hard and a less hard abrasive.</p> |
