Abstract
A fragrant material that imparts a pleasant fragrance when set out at ambient temperature or when placed in heated water. The fragrant material comprises an aggregate of small sodium chloride granules such as are produced by vacuum granulation, the granules formed into a molded shape, e.g. as a plurality of discrete pellets, or in a loose state, and having a fragrant oil and optionally a water soluble dye dispersed in the material. Also disclosed is a fragrant material comprising the combination of salt granules with a minor amount of finely divided inert particles, and a water-soluble dye. Other features that enhance performance and enable the product to be of low cost are also described.
