Abstract:
A granular composition for carrying and retaining a liquid phase, substantially water-free, volatile organic functional ingredient, said granular composition comprising at least 40% by weight of an amorphous silica and the amorphous silica having a surface area of at least 550 m2/g, a pore volume from about 1.0 to about 2.5 ml/g and a particle size of no more than 50 microns, the granules of said composition disintegrating when contacted with water and having:a particle size greater than from 200 and up to 2000 microns; and a dry strength such that no more than 30% by weight pass through a 212 micron sieve when subjected to the attrition test defined herein.
