  • changing the percentage of co-formulant, auxiliary formula or active substance. This percentage must not change significantly. For an auxiliary formula, this change can be no more than 25% relative to the previous formula. The content of active substance can change by no more than 10%.

In general: for a minor change no studies have to be submitted and no risk assessments have to be prepared.
