| abstract |
The present invention relates to an anti-caking agent for the treatment of granulate products, where the anti-caking agent is a salt having the general formula (Ia): R1-AB-R2-BA-R1, or the general formula (Ib): R1-BA-R2-AB-R1, in which the groups R1 independently represent monovalent hydrophobic organic groups, the group R2 represents divalent hydrophobic organic groups, the groups A represent independently anionic groups and the groups B represent independently cationic groups. The groups A preferably represent carboxylate ion groups and the groups B preferably represent ammonium ion groups. An anti-caking agent of this kind is very suitable for inhibiting the caking tendency of fertilizers. |
