Perfumes for Rinse-Off Applications
U.S. Patent No. 7,446,079 B2: Givaudan Fragrances Corp. has patented perfumes for rinse-off systems. The method is comprised of calculating values of odor detection threshold, odor detection threshold in air, acceleration (Γ) flash water release (Ω) values for a group of odorants; selecting at least three different odorants, each odorant having an acceleration (Γ) value of about 1000 or greater, a flash release (Ω) value selected from the group consisting of approximately 10 or greater, from approximately 0.07-10, and from about 0.007-0.07, and a property selected from the group consisting of an odor detection threshold of about 50 parts per billion or less, an odor detection threshold in air of about 0.025 mg/m3 or less, and combinations of these; and placing the perfume composition in a wash-off system to provide an initial water release and a minimal residual perfume on a targeted surface after wash-off.
