Abstract

A self-dispersing particulate composition, in the form of pellets, prills, flakes or granules, containing particles with a first functional component that is a glassy solid with small, dispersed pockets of pressurized gas and, in the same or different particles, a second functional component that is a special-use material having at least one additional utility. Special use materials include, for example, a deicer, a fertilizer, a drain cleaner, an insecticide, a carpet cleaner, and a powdered laundry detergent. Dissolution of the glassy material liberates pressurized gas, causing repositioning of the special-use material.
