A non-explosive water in oil emulsion fertilizer composition is provided which comprises:

Water-in-oil emulsion fertilizer compositions

A non-explosive water in oil emulsion fertilizer composition comprising: a discontinuous aqueous phase comprising at least one fertilizer component; a continuous oil phase; an emulsifier comprising the reaction product of at least one succinic acylating agent and at least one co-reactant selected from the group consisting of: primary alkanol amines, secondary alkanol amines, tertiary alkanol amines, primary amines, secondary amines, tertiary amines, poly-amines, alcohols, polyols, and phenols is disclosed. The ferilizer compositions provide for delayed release of the fertilizer components.

A non-explosive water in oil emulsion fertilizer composition is provided which comprises: a discontinuous aqueous phase comprising at least one fertilizer component; a continuous oil phase; an emulsifier comprising the reaction product of at least one hydrocarbyl substituted succinic anhydride acylating agent and at least one tertiary alkanol amine.

Water-in-oil emulsifiers for slow release fertilizers using tertiary

This invention relates to water-in-oil emulsion explosives in which an oxidizing material is contained in the discontinuous water phase, and the continuous oil phase acts as a carbonaceous fuel. More particularly, this invention relates to such explosives in which polyfunctional carboxylic acids, sulfonic acids, or phosphorous-containing acids, soluble in the oil phase, are caused to cross-link using an inorganic cross-linker, thereby causing the viscosity of the emulsion to increase.
