Coated particles and their uses
Provided are coated particles and methods of their use for providing healthcare benefits. More specifically, the present invention provides amino acid and/or polymer-coated particles, or particles coated with other materials, for binding to, or otherwise associating with, surfaces of the oral cavity.
1. A coated particle which binds to, adheres or associates with the surfaces of the oral cavity, comprising:
(a) a substrate which is a particle or nanoparticle made from poly(lactic-co-glycolic acid) (“PLGA”), and
(b) a coating covalently bonded to the substrate which is ethyl lauroyl arginate HCl.
2. The particle according to claim 1 further comprising an active ingredient.
3. A method of providing a benefit to the oral cavity comprising introducing to said oral cavity a coated particle according to claim 1 .
4. A method of providing a benefit to the oral cavity comprising introducing to said oral cavity a coated particle according to claim 2 .
