摘要

Method for applying micro/nano quantity of odorants on a medium (preferably washing-, cleaning-preserving agents and/or their precursors) comprises spraying a mixture (in the form of liquid or paste) of the odorants and carbon dioxide at a pressure where the carbon dioxide is released in the form of gas and condensing the odorants in liquid or solid form on the medium by cooling. Independent claims are also included for: (1) a medium comprising the odorants obtained by the method; (2) aromatic substance comprising the medium (preferably in solid form) containing 10 (preferably 50) wt.% of the total aroma material related to the total weight of the aroma material; (3) the preparation of the odorants; (4) odorants in micro/nano quantity obtained by the method; and (5) a product comprising product medium and the odorants.
