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.
Claims18
Conditioned composition comprising at least one liquid absorbed on a support containing a precipitated silica, characterized in that the said silica is in the form of substantially spherical beads and has:
- an average bead size in excess of 150 μm,
- a packed filling density (PFD) in excess of 0.29,
- a 75 μm screen oversize of at least 92% by weight.
Use of a precipitated silica as a liquid support, in particular as a liquid supplement for animal feed, characterized in that the said silica is in the form of substantially spherical beads and has:
- an average bead size in excess of 150 μm, preferably in excess of 200 μm,
- a packed filling density (PFD) in excess of 0.29, preferably of at least 0.30,
- a 75 μm screen oversize of at least 92% by weight, preferably of at least 93% by weight.
