Abstract
Process for reducing the density of solid detergent ingredients by forming said ingredients into hollow-core particles. The density of ingredients such as sodium citrate, sodium carbonate and/or sodium silicate, when formed into such hollow-core particles, allows them to be stably incorporated into non-aqueous liquid laundry detergents.
