Abstract
The present invention relates to unique interdental delivery devices, other than dental floss, which are suitable for cleaning, massaging, and/or treating surfaces of teeth and gums including interproximal and subgingival areas; wherein these devices contain ULTRAMULSION.TM. dispersions of high viscosity silicones dispersed in surfactants, these dispersions are released into the oral cavity from these devices during use wherein the dispersed silicone: PA1 a. is insoluble in the surfactant and oriented so as to form coatings in the oral cavity with enhanced substantivity, PA1 b. functions as a reservoir for various lipid soluble and/or liquid dispersible ingredients to be released onto oral cavity surfaces, and PA1 c. has a particle size from between about 0.1 and about 10 microns with from between about 80% and about 95% of the particles within this range.
