Compositions comprising alginates with high guluronic acid/mannuronic acid ratio for use in the treatment of dentine hypersensitivity
View Patent ↗The present invention relates to oral care compositions comprising certain alginates for the treatment of dentine hypersensitivity and to their use.
1. A method for treating dentine hypersensitivity which comprises applying an effective amount of an oral care composition comprising as an active agent an alginate which is Manugel LBA having a ratio of α-L-guluronic acid to β-D-mannuronic of greater than 1.5:1.0 and a molecular weight range of from about 2×10 4 to about 1.35×10 5 Daltons and a viscosity in the range 1 to 100 cP when measured as a 1% w/w solution in water at 37° C., to an individual in need thereof.
2. The method as claimed in claim 1 , wherein the alginate is present in an amount from about 0.5% wt. to about 6% wt. of the composition.
3. The method as claimed in claim 1 , wherein the composition is in the form of a mouthwash.
