NAPKINS FOR ORAL HYGIENE PROCEDURES CONTAINING MICROCAPSULES Russian patent published in 2021 - IPC A61K6/52 A61Q11/00 

FIELD: personal hygiene products.

SUBSTANCE: invention relates to disposable products intended for hygienic procedures in the oral cavity. A napkin for oral hygiene procedures consists of a non-woven textile base impregnated with components for oral hygiene procedures, while at least some components for oral hygiene procedures are encapsulated in microcapsules placed on the surface of the non-woven textile base. The napkin is characterized by the fact that it contains two different types of microcapsules: mechanically destructible microcapsules capable of withstanding a pressure equal to 20 g/cm², and about 90% of these microcapsules are made with the possibility of destruction at a pressure equal to 500 g/cm², microcapsules with controlled diffusion are able to withstand a pressure of about 2000 g/cm². Mechanically destructible microcapsules provide the possibility of releasing their contents when the microcapsule wall is destroyed, the microcapsule wall is made of a polymer insoluble in water. Microcapsules with controlled diffusion are made with the possibility of releasing their contents by the permeability of the content components through the microcapsule wall. In this case, the microcapsule wall consists of a polymer insoluble in water.

EFFECT: invention provides both an immediate effect of cleansing and freshness, and an enhanced long-term effect after some time.
