Methods of preparing a dentifrice comprising polymer matrix film with a low solubility falvorant therein are disclosed. The methods comprise combining a polymer matrix film that are free of a low solubility flavorant with a dentifrice base comprising a low solubility flavorant and maintaining the combined polymer matrix film with the dentifrice base comprising low solubility flavorant for an amount of time sufficient for an amount of a low solubility flavorant to transfer from the dentifrice base comprising low solubility flavorant to the polymer matrix film. Products comprising low solubility flavorant-free polymer matrix film in a dentifrice base comprising low solubility flavorant are also disclosed.揭示一種製備聚合物基質膜內包含具有低溶解度香料之潔齒劑的方法。該方法包含混合無低溶解度香料之聚合物基質膜與包含低溶解度香料之潔齒劑基料,以及使該經混合聚合物基質膜和潔齒劑基料維持足以將有效量低溶解度香料從該潔齒劑基料傳遞至該聚合物基質膜的一段時間。亦揭示於包含低溶解度香料之潔齒劑基料內包含無低溶解度香料聚合物基質膜的產品。
