ORAL CARE COMPOSITIONS AND METHODS FOR PREPARING THEM Russian patent published in 2015 - IPC A61K8/73 A61K8/92 A61K8/97 A61Q11/00 

FIELD: medicine.

SUBSTANCE: method involves: a) preparing a polymer matrix film containing a water-soluble polymer and a hydrophobic/lipophilic additive and being substantially free from a poorly-soluble flavour; b) preparing a dental care base containing the poorly-soluble flavour; c) combining the polymer matrix film with the prepared base; and d) keeping the combined polymer matrix film and base for the period of time adequate to transfer an effective amount of the above flavour from the base of the dental care agent into the above polymer matrix film. That involves using the flavour specified in a certain list of poorly-soluble flavours (menthol, thyme oil, etc.), and one or more hydrophobic/lipophilic additives specified in a group of specific additives (Vaseline, silicone oil, etc.). The agent prepared by the above method has the same characteristics as the agents prepared by a common method, when the prepared films containing the flavour are added to the base of the dental care agent.

EFFECT: method provides such advantages as compared to the common method for preparing these agent, as a possibility to avoid using ethanol in preparing the film, otherwise required to solve the flavours if following the common method for preparing the film, as well as eliminating the flavour loss in heating during the film drying.
