Oral Care Compositions Having Improved Rheology

摘要

Oral care compositions comprising have improved stability due to the removal of stannous ions and the inclusion of low molecular weight polyethylene glycols (PEGs). Compositions containing a source of zinc ions and PEG having a weight average molecular weight of 300 Da to 8000 Da and used for treating the oral cavity comprising administering to the oral cavity an oral care composition according to the present invention.

主权项

1. An oral care composition comprising:
a) from 0.01% to 5% by weight of a zinc ion source; b) from 0.01% to 5% by weight of a flavor composition; c) from 30% to 75% by weight of a total water content; d) from 0.1% to 3% by weight of a first humectant comprising polyethylene glycols (PEGs) having a weight average molecular weight range of from 300 Da to 8,000 Da; and e) from 0.01% to 5% by weight of a thickener system comprising a combination of carboxymethyl cellulose (CMC), hydroxyethyl cellulose (HEC), and carrageenan; wherein the oral care composition is substantially free of stannous ions.
