titleOfInvention |
Ph modulated films for delivery of actives |
abstract |
The invention relates to pH modulated films and methods of their preparation. The film compositions include at least one component having a non-neutral pH when combined with water; and a pH modulated polymer system selected to reduce or prevent synerisis when combined with the non-neutral component in combination with aqueous media. The films demonstrate a non-self-aggregating uniform heterogeneity. Desirably, the films disintegrate in water and may be formed by a controlled drying process, extrusion process, or other process that maintains the required uniformity of the film. |
