By compressing the aerosol, Unilever has reduced the weight from 16% to 33%. The new packaging uses 20% less aluminium and lowers carbon footprint by 20% per bottle. Thanks to the new spray system, the compressed deodorant lasts as long as the old bottles. This major technological innovation is not covered by a patent and Unilever has therefore opened it up to the entire sector. Thanks to this transparency, the whole sector could benefit from even greater environmental gains.
