Oral care compositions comprising hops beta acids and fluoride ions
Oral care compositions with an anticaries or anticavity effect. Oral care compositions that have an extract from a species in the Humulus family and an anticaries drug, such as a fluoride ion source. Oral care compositions have fluoride and hops beta acid, such as from an extract from Humulus lupulus . Oral care compositions have a fluoride ion source and a hops beta acid derived from an extract of Humulus lupulus.
