Abstract
Disclosed is a system for delivering an oral care substance to the oral cavity comprising: (a) a delivery composition comprised of: (i) an organosiloxane resin; (ii) a volatile carrier capable of solubilizing the organosiloxane resin; (iii) a rheology modifier; and (iv) at least one oral care substance; and (b) a protective composition comprised of: (i) an organosiloxane resin; and (ii) a volatile carrier capable of solubilizing the organosiloxane resin. Further disclosed is a system for delivering an oral care substance to the oral cavity comprising: (a) a delivery composition comprised of: (i) an organosiloxane resin; (ii) a fluid diorganopolysiloxane-based polymer; (iii) a volatile carrier capable of solubilizing the organosiloxane resin and the fluid diorganopolysiloxane-based polymer; (iv) a rheology modifier; and (v) at least one oral care substance; and (b) a protective composition comprised of: (i) an organosiloxane resin; and (ii) a volatile carrier capable of solubilizing the organosiloxane resin. The protective composition may further comprise a fluid diorganopolysiloxane-based polymer and/or a rheology modifier. Still further disclosed is a method of using these systems…
