The invention relates to a composition, which is simultaneously anticlumping and water-repellent, for salts, simple and complex fertilizers. This composition contains:

Composition which is simultaneously anticlumping and water-repellant for

Anticlumping composition intended for fertilizers comprising an aqueous solution of at least one surfactive agent and at least one high molecular weight polymer soluble in the said aqueous solution, wherein the surfactive agent is consisting of a phosphoric ester acid salt.

Anticlumping composition and anticlumping process for fertilizers

Internal additive for the preparation of prills of ammonium nitrate comprising, in aqueous solution, a mixture of at least one salt of sulphonic acid and of at least one salt of polycarboxylic acid.

Internal additive and process for the preparation of certain

Process for inhibiting the corrosive characteristics of a nitrogenous fertilizing solution comprising incorporating in said nitrogenous fertilizing solution at the moment of its constitution, about 50 to about 150 ppm of at least one of the linear esters of acid phosphates having the formulae; ##STR1## wherein R1 and R2 which are identical or different from one another, are selected from the group consisting of the n-heptyl, n-octyl, n-nonyl and n-decyl radicals.

Agent inhibiting the corrosive characteristics of nitrogenous

Anti-clumping product for salts, simple and complex fertilizers as well as for nitrogenous derivatives, especially on the basis of ammonium nitrate, which might in particular be used in connection with explosives, consisting of a metallic salt of an acid phosphate ester having the general formulas I and II: ##STR1## wherein: R.sub.1 designates an alkylene group having from 2 to 4 carbon atoms,

Anti-clumping products, compositions containing the said products and

An anti-clumping product for salts and for simple and complex fertilizers is essentially constituted by a combination of one or several amine salts of alkylary-1-sulfonic acids and of one or several amine salts of acid phosphate esters, in the presence possibly of an excess of amine.
