摘要：
Fragrance control is provided by articles of manufacture including various solid state fragrancing objects, methods of using such objects, and systems that employ one or more such objects. The fragrancing object can be easy to manufacture, long lasting, provide fragrance that is consistently released over time, provide an indication to the user that the object needs to be replaced, and can hold a desired ratio of fragrance. The fragrancing object can include a first material comprising a polyether block amide, a second material comprising a polyolefin elastomer (POE), and a fragrance component such as a fragrance oil.
