Abstract
Oral care compositions, oral care systems, oral surface-binding peptides, and a method for applying particles to an oral surface are provided. The oral care system comprises at least one peptidic component comprising a first binding element having affinity for an oral surface and a second binding element having affinity for a ligand property of a particle.
Claims34
An oral care system comprising:
- (a) a peptide composition comprising
- (i) a first binding element having affinity for an oral surface with a MB50 value of 10−5 molar or less;
- and
- (ii) a second binding element;
- and
- (b) a composition comprising particles, said particles comprising
- (i) a benefit agent;
- and
- (ii) a ligand property;
- wherein said particles have an average particle size in the range of 0.01 micron to 10 microns;
- and
- wherein the second binding element and the ligand property associate with each other non-covalently or by chelation.
A method for applying an oral care benefit agent to an oral surface comprising:
- (a) providing an oral care system comprising
- (i) a peptide composition comprising
- (1) a first binding element having affinity for an oral surface with a MB50 value of 10−5 molar or less;
- and
- (2) a second binding element;
- and
- (ii) a composition comprising particles, said particles comprising
- (1) a benefit agent;
- and
- (2) a ligand property;
- wherein said particles have an average particle size in the range of 0.01 micron to 10 microns;
- and wherein the second binding element and the ligand property associate with each other non-covalently or by chelation;
- and
- (b) contacting an oral surface with the oral care system of (a) whereby the benefit agent is applied to said oral surface.
A polypeptide comprising an amino acid sequence selected from the group consisting of SEQ ID NOs:
- 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 120, 121, 122, 123, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, and 144.
A polypeptide comprising an amino acid sequence selected from the group consisting of 161, 162, 163, and 166.
