Abstract
The invention concerns a conditioned composition comprising at least a liquid absorbed on a support containing a precipitated silica, said silica being in the form of substantially spherical beads and having: a mean pellet size greater than 150 μm; a filling density in compact state(DRT) greater than 0.29; an oversize rate for a grid with mesh aperture size of 75 μm of at least 92% by weight. The invention also concerns the use of such a silica as a support for liquid.
