An active principle-based coated particle in which both a core and a coating contain active principle, wherein the core contains a first active principle while the coating contains from 60 to 99% by weight of a second active principle, which is different in nature, the rest up to 100% by weight of the coating comprising at least one binding agent and optionally an antistatic agent.
A method for producing a particle coated with active principle, a core of which contains a first active principle while a coating contains a second active principle, comprising the following steps:
- preparing the core comprising the first active principle,
- coating the core thus obtained by spraying a solution or suspension comprising from 60 to 99% by weight of a second active principle and at least one binding agent and optionally an antistatic agent, and
- drying.
