ABSTRACT:
Perfume particles which are especially useful when incorporated into a fabric softening composition are formed by adsorbing a perfume composition onto silica particles. Those particles having a diameter of greater than about one micron also can be used to reduce the shiny appearance of visible softener spots which occasionally are present on fabrics treated with said fabric softening compositions and to maintain a relatively constant viscosity of the molten softening composition.
