Personal cleansing compositions, especially body washes and shampoos, are disclosed comprising surfactant, fragrance oil and less than about 7.5% non-fragrance oil, wherein the surfactant and fragrance oil form:a) a first micellar phase; andb) a second phase which rotates polarized light.

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 which doesn't interfere with the formation of the entrapment structure on the surface.The present methods and compositions can improve fragrance perception, by overcoming the differences in fragrance perception that result from different surface, for example, skin, hydration levels and / or different surface types.

The present invention relates to a microcapsule particle composition that is composed of a sol-gel material. The microcapsule particle composition is well suited for personal care and cleaning products. The invention provides a method of preparing microcapsules containing active ingredients in a core, including comprises the steps of first mixing an appropriate amount sol-gel precursor and fragrance oil, followed by cooling of the mixture obtained. The next step in the process is to prepare a surfactant solution by dissolving an appropriate amount of surfactant in water and then cooling the surfactant solution. In the next step the sol-gel precursor and fragrance oil are added to the surfactant solution and then the mixture is homogenized. A defoamer is added as needed and the mixture is allowed to cure to form the microcapsule particle composition.

The present invention provides a method of applying a fragrance to a surface such as skin and / or hair. The method comprises applying to one area of the surface a first composition wherein the first composition comprises at least one first fragrance oil; at least one first cyclic oligosaccharide, wherein the at least one first fragrance oil and the at least one first cyclic oligosaccharide form a complex, which complex is dissolved or dispersed in the first composition; and a first solvent, wherein the first solvent has a dielectric constant at 25° C. of greater than or equal to 43. The method also comprises simultaneously or sequentially, in either order, applying to the one area or an area adjacent thereto a second composition wherein the second composition comprises at least one second fragrance oil; and a second solvent wherein the at least one second fragrance oil is soluble or is dispersed at 25° C. in the second solvent.
