abstract |
Embodiments of the invention provide a composition of a particulate coformulation which includes particles containing an active substance and an additive, wherein each particle contains a relative additive concentration increasing radially outwards from a particle center to a particle surface along a finite gradient. In one example, the particle surface is an additive-rich surface without a distinct physical boundary between the particle center and the particle surface. The relative additive concentration may have a continuous rate of change across the finite gradient. In some examples, an active substance:additive ratio of the particle surface is sufficiently low to form a protective surface layer around the active substance. Generally, the particle surface is free of the active substance. |
