    摘要： Controlled release, particulate fertilizer products having a water soluble fertilizer central mass encased in a plurality of water insoluble, abrasion resistant coatings plus unique coating compositions and methods for the production of such products are disclosed. At least one essential inner coating is a urethane reaction product of (1) a polyisocyanate selected from diphenylmethane diisocyanate, toluene diisocyanate, derivatives thereof, polymers thereof and mixtures thereof which contain about 1.5 to 3 isocyannate groups per molecule and between about 10 and 50% NCO, and (2) a polyol having about 2 to 6 hydroxyl moieties and at least one alkyl moiety containing about 10 to 22 carbon atoms, e.g. hydrogenated castor oil. An essential outer coating is formed of an organic wax having a drop melting point of between about 50.degree. and 120.degree. C.

    摘要： Compositions which are particulate water insoluble and nondispersible salts of certain surface active sulfate or sulfonate anions and surface active quaternary ammonium cations are described. They are useful as wash cycle laundry softener-antistatic compositions, in both liquid and powdered laundry products and also dispersed in solid matrices. The particle size is from 50 to 500 microns.
