Abstract
Disclosed is a delivery system for delivering an oral care substance to the oral cavity, the delivery system comprising: (a) a removable backing strip having sufficient flexibility so as to be readily conformable to an oral surface when the delivery system is placed thereagainst; and (b) an oral care composition applied to the strip of material such that when the delivery system is placed on the oral surface the oral care composition contacts the oral surface, the oral care composition comprising: (i) an organosiloxane resin; (ii) a theology modifier; and (iii) at least one oral care substance; wherein the oral care composition remains on the oral surface after the backing strip is removed. Further disclosed are such delivery systems in which the oral care composition further comprises fluid diorganopolysiloxane-based polymers; such compositions may further comprise carriers for solubilizing the organosiloxane resin and the fluid diorganopolysiloxane-based polymers. Still further disclosed are methods of using the delivery systems.
