Abstract
A scent intensity regulating composition (RIS composition). The RIS composition includes at least two of: a first scent intensity regulating component (RIS component) having an average vapor pressure (VP) greater than 0.3 Torr at 25° C.; a second RIS component having an average VP from 0.07 to 0.3 Torr at 25° C.; and a third RIS component having an average VP from 0.0099 to 0.07 Torr at 25° C. Each of the first, second, and third RIS components is characterized by an Odor Detection Threshold (ODT) of greater than 20 ppb.
Claims17
A scent intensity regulating composition (RIS composition), wherein the RIS composition comprises:
- from 5% to 30% by weight of the RIS composition of a first scent intensity regulating component (RIS component) having an average vapor pressure (VP) greater than 0.3 Torr at 25° C.;
- from 20% to 50% by weight of the RIS composition of second RIS component having an average VP from 0.07 to 0.3 Torr at 25° C., wherein the second RIS component is selected from the group consisting of:
- dimethyl hexanedioate (DMA), ethyl 3,5,5-trimethylhexanoate, dimethyl butanedioate, diethyl propanedioate, ethyl 3-acetyloxyhexanoate, methyl 5-acetyloxyhexanoate, 3-O-butyl 1-O-ethyl propanedioate, dipropan-2-yl hexanedioate, (4-methoxyphenyl) methyl formate, ethyl 3-hydroxyhexanoate, and mixtures thereof;
- and
- from 10% to 45% by weight of the RIS composition of a third RIS component having an average VP from 0.0099 to 0.07 Torr at 25° C.;
- wherein each of the first RIS component, the second RIS component, and the third RIS component is characterized by an Odor Detection Threshold (ODT) of greater than 20 ppb.
