Claims22
A toothpaste composition comprising
- a. zinc in complex with an amino acid, and
- b. a humectant system comprising a structuring humectant, wherein the structuring humectant is polyethylene glycol (PEG) in an amount of 1-10% by weight of the toothpaste composition and propylene glycol (PG) in an amount of 1-10% by weight of the toothpaste composition;
- and
- c. an organic or inorganic acid selected from one or more of phosphoric acid, hydrochloric acid, sulfuric acid, citric acid, tartaric acid, malic acid, maleic acid, fumaric acid, lactic acid, gluconic acid, and benzoic acid;
- wherein the composition has a stable yield stress as measured by a Brookfield Viscometer using Spindle V74 at 1 RPM.
