Beschreibung
Zusammenfassung:	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. La présente invention concerne une composition granulaire pour absorber des liquides, la composition comprenant de la perlite, un superabsorbant, un colorant indicateur de pH, et une quantité mineure d'eau. Selon un mode de réalisation préféré de l'invention, la composition en question comprend environ 80 pour cent en poids de perlite, environ 5 pour cent en poids de SAP, environ 0,0125 pour cent en poids de colorant indicateur de pH (de manière préférée entre toutes la phénolphtaléine), et d'environ 7 à environ 9 pour cent en poids d'eau dans le produit final.
