The present invention relates to new additives for preventing caking and humectation of nitrogenous fertilizers having a material composition which is free of fatty amines or their salts and characterized in that it comprises: (i) between 50 and 90 parts by weight of a macrocrystalline paraffin having a viscosity at 100 DEG C between 2 and 5 cSt (ASTM D-455), with a paraffin oil content under 20% by weight (ASTM D-721); (ii) between 0 and 20 parts by weight of a paraffinic oil having a viscosity at 100 DEG C between 3 and 40 cSt (ASTM D-455); (iii) between 0 and 10 parts by weight of a microcrystalline paraffin having a viscosity at 100 DEG C between 10 and 25 cSt (ASTM D-455) with a paraffin oil content not greater than 15% by weight (ASTM D-721); (iv) between 10 and 50 parts by weight of phosphoric acid monoesters and/or diesters of C2-C22 alkyl or C2-C12 arylalkyl, optionally alkoxylated; so that the total paraffin oil content of the composition is greater than 1% by weight.
