Abstract

Claims (23)

1 . A system for delivering an active agent to an oral cavity comprising:

(a) an oral care composition comprising a jammed oil-in water emulsion, wherein the jammed oil-in-water emulsion exhibits no more than 5% macroscopic separation after 48 hours at 23° C., the jammed oil-in-water emulsion comprising:

(i) from 1% to 15%, by weight of the jammed oil-in water emulsion, of an at least partially continuous aqueous phase,

(ii) a discontinuous hydrophobic phase,

(iii) the active agent, and

(iv) an emulsifier, wherein the emulsifier comprises polysorbate 20, polysorbate 40, sodium lauryl sulfate, or combinations thereof; and

(b) a delivery carrier.

2 . The system of claim 1 , wherein the system further comprises a device capable of producing electromagnetic radiation.

3 . The system of claim 1 , wherein the oral care composition comprises from about 80% to about 99%, by weight of the composition, of the discontinuous hydrophobic phase.

4 . The system of claim 1 , wherein the oral care composition comprises from about 85% to about 95%, by weight of the composition, of the discontinuous hydrophobic phase.

5 . The system of claim 1 , wherein the oral care composition comprises from about 5% to about 15%, by weight of the composition, of the at least partially continuous aqueous phase.

6 . The system of claim 1 , wherein the oral care composition comprises from about 85% to about 95%, by weight of the composition, of the discontinuous hydrophobic phase and from about 5% to about 15%, by weight of the composition, of the at least partially continuous aqueous phase.

7 . The system of claim 1 , wherein the at least partially continuous aqueous phase comprises the active agent.

8 . The system of claim 1 , wherein the discontinuous hydrophobic phase comprises the active agent.

9 . The system of claim 1 , wherein the active agent comprises a bleaching agent, an anti-caries agent, an anti-tartar agent, a remineralization agent, a wound healing agent, an anti-inflammatory agent, an antibacterial agent, a metal ion source, an anti-glycolytic agent, an amino acid, a probiotic, a prebiotic, a postbiotic, a polyphosphate, a buffer, an anti-sensitivity agent, or combinations thereof.

10 . The system of claim 1 , wherein the active agent comprises a bleaching agent, a vitamin, or combinations thereof.

11 . The system of claim 1 , wherein the oral care composition comprises from about 0.01% to about 10%, by weight of the composition, of the emulsifier.

12 . The system of claim 1 , wherein the emulsifier comprises one or more hydrophobic tails, the one or more hydrophobic tails having from about 6 to about 20 carbon atoms.

13 . The system of claim 12 , wherein the one or more hydrophobic tails has up to 4 branches.

14 . The system of claim 2 , wherein the electromagnetic radiation has a wavelength of from 1 nm to 1 mm.

15 . The system of claim 2 , wherein the electromagnetic radiation has a wavelength of from about 100 nm to 900 nm.

16 . The system of claim 1 , wherein the delivery carrier comprises a tray, a strip, or a combination thereof.

17 . The system of claim 1 , wherein the discontinuous hydrophobic phase comprises at least 84%, by weight of the jammed oil-in water emulsion, of petrolatum, mineral oil, or a combination thereof.
