1. A storage-stable liquid nano-particle emulsion comprising nano-particles, wherein the nano-particles comprise:
a lipid component having a viscosity of less than 100 cP at 25° C. and a Kauri Butanol solvency of greater than 25 Kb, wherein the lipid component comprises a terpene;
a secondary alkoxylated alcohol having a 10 to 16 carbon chain and 4 to 35 degrees of ethoxylation or propoxylation, wherein the secondary alkoxylated alcohol is derived from a starting compound having a viscosity of less than 1000 cP at 50° C.; and
sodium dodecyl benzene sulfonate,
wherein the nano-particles have a D50 and a mean average particle size distribution of less than 100 nm, wherein the nano-particles are diluted with water to form a uniform storage-stable liquid nano-particle emulsion, and
wherein the uniform storage-stable nano-particle emulsion is adapted for use as a carrier for an agricultural chemistry.
