An oral care, personal care or cleansing composition with a carrier comprising a functional material and at least two polymers. One polymer has a greater solubility in water than the other polymer; one of the polymers may be water- soluble and the other polymer water-insoluble. The polymers are selected and apportioned to provide at least one of the following: (1) a desired stability of the film in the composition. (2) a desired rate of disintegration of the film during use of the composition, and (3) a desired rate of delivery of the functional material during use of the composition.

La présente invention concerne des soins buccaux, des soins individuels ou une composition de nettoyage avec un excipient comprenant un matériau fonctionnel et au moins deux polymères. Un polymère fait preuve d'une plus grande hydrosolubilité que l~autre polymère ; l~un des polymères peut être hydrosoluble et l~autre polymère non hydrosoluble. Les polymères sont sélectionnés et répartis en vue de fournir au moins l~une des qualités suivantes : (1) une stabilité souhaitée du film dans la composition, (2) une vitesse de désintégration souhaitée du film durant l~utilisation de la composition et (3) une vitesse de libération souhaitée du matériau fonctionnel durant l~utilisation de la composition.
