Abstract
Oral care compositions and, particularly, oral care compositions having enhanced stannous ion stability are disclosed herein. In accordance with at least one aspect, provided is an oral care composition comprising: a stannous source; and a cross-linked polyacrylic acid and/or a salt thereof, wherein the personal care composition has a weight ratio of the stannous source to the cross-linked polyacrylic acid and/or a salt thereof of about 4:1 to about 1:4.
Claims20
An oral care composition comprising:
- a stannous source;
- and
- a cross-linked polyacrylic acid and/or a salt thereof,
- wherein the personal care composition has a weight ratio of the stannous source to the cross-linked polyacrylic acid and/or a salt thereof of about 4:1 to about 1:4.
An oral care composition comprising:
- a stannous source;
- a polymer system comprising a cross-linked polyacrylic acid, a phosphate/acrylate copolymer, a salt thereof, or a combination thereof;
- and
- a polyphosphate and/or a salt thereof,
- wherein the oral care composition has a pH of about 5 or more and all weight percentages are based on the total weight of the oral care composition.
A method for preparing an oral care composition comprising:
- cross-linking the polyacrylic acid and/or the salt thereof to form a cross-linked polyacrylic acid and/or salt thereof, and
- chelating a stannous ion source with the cross-linked polyacrylic acid and/or the salt thereof.
