Decyl Propionate is primarily used as a fragrance component or texture enhancer rather than a bioactive. Because its function is sensory and it is capped at 3% for safety, it is rarely 'dusted' in the traditional sense, though its presence at very low levels (below 0.1%) suggests it is only serving as a scent adjuvant.
