description The present invention relates to particle compositions comprising a core particle that is partially coated with a first hydrophilic deposit and a hydrophobic polymeric finish, contains a small amount of water, and a compatible active present in the deposit, the finish or both. Additional alternating deposits, hydrophobic, hydrophilic or both, can be present between the first hydrophilic deposit and the hydrophobic polymeric finish. Similarly, additional compatible actives can be present in one or more of the additional alternating deposits. The invention also relates to methods of preparing the particle compositions.
