Abstract
Official abstract text for this publication.
An oral care composition includes an effective amount of a basic amino acid in free or salt form; and an effective amount of calcium silicate particles. The calcium silicate particles have an average diameter of less than about 5 microns, such that they can occlude dentinal tubules of the teeth. An oral care method includes applying the composition to an oral cavity of a subject to reduce or inhibit hypersensitivity of the teeth and to achieve other benefits.
First claim
Opening claim text (preview).
What is claimed is: 1. An oral care composition for reducing hypersensitivity of the tooth comprising:□a. an effective amount of a basic amino acid in free or salt form; and □b. an effective amount of calcium silicate particles, wherein the calcium silicate particles have an average diameter of less than 5 microns, wherein the particles have a d50 of 2 μm to 5 μm, and a d90 of 5 μm to 10 μm, and a cumulative volume percentage at 3.95 of at least 50%.
