Apparatus and process for effecting controlled distribution of fragrance accords

摘要

Air care apparatus which effects controlled distribution of fragrance and accords to the environment proximate the apparatus from a manifold in which controlled vapor phase fragrance accord mixing takes place, with respect to controlled component concentration and/or concentration gradient and proportion and controlled relative rates of delivery for each fragrance accord. Also described is a process for using such apparatus. Each of the vapor phase accords being distributed has substantially the same composition on a molar basis as each of the corresponding liquid fragrance accords contained in each one of the several holding vessels which is part of the apparatus. Each of the accord components of each accord has a maximum vapor pressure variance of 130% and a maximum heat of vaporization variance of 40%. Optionally, the apparatus may be operated in conjunction with an electronic program controller.
