Abstract
The invention provides a method for improving release, on a surface, of a fragrance from an entrapment structure of at least one fragrance oil and at least one entrapment material. The method destabilizes the entrapment structure by providing at least one trigger molecule which preferentially associates with the entrapment material; and/or at least one release agent which at least partially disrupts the entrapment structure.The invention also provides a composition for improving release of a fragrance from a surface. The composition comprises at least one fragrance oil; at least one entrapment material, the at least one fragrance oil and the at least one entrapment material being capable, in use, of forming an entrapment structure on the surface. The composition also comprises at least one destabilizing material, which permits formation of the entrapment structure on the surface but which destabilizing material can, in use, destabilize the entrapment structure by providing at least one trigger molecule which preferentially associates with the entrapment material; and/or at least one release agent which partially disrupts the entrapment structure; and at least one compatible solvent…
