Abstract:
An granular composition for absorbing liquids, the composition comprising perlite, super-absorbent polymer, a pH-indicating dye, and a minor amount of water. According to one preferred embodiment of the invention, the subject composition comprises about 80 weight percent perlite, about 5 weight percent SAP, about 0.0125 weight percent pH indicating dye (most preferably phenolphthalein), and from about 7 to about 9 weight percent water in the final product.
