Disclosed are compounds having the ability to modulate, namely to improve, enhance and or modify fragrance compositions due to their ability to inhibit cytochrome P450 enzymes, e.g. CYP2A13 and CYP2B6.
Encapsulated perfume composition comprising at least one aminoplast core-shell microcapsule dispersed in a suspending medium, the microcapsule comprising a perfume-containing core encapsulated in a shell, said shell comprising a network of cross-linked aminoplast resin, wherein 75-100% of the resin comprises 50-90%, preferably from 60-85%, of a terpolymer and from 10-50%, preferably from 10-25%, of a polymeric stabilizer; the terpolymer comprising:
(a) from 20-35 wt %, preferably 22-30% by weight of moieties derived from at least one triamine,
(b) from 30-60 wt %, preferably 40-55% by weight of moieties derived from at least one diamine,
(c) from 20-35 wt %, preferably 22-30% by weight of moieties derived from the group consisting of alkylene and alkylenoxy moieties having 1 to 6 methylene units, preferably 1 to 4 methylene units and most preferably 1 methylene unit.
The encapsulated perfume composition is useful for the storage and dissemination of fragrance in various products, such as laundry products and fabric care products.
An encapsulated perfume composition comprising at least one perfume-containing aminoplast core-shell microcapsule dispersed in an aqueous suspending medium, the microcapsule being characterized in that it bears a positive charge.
An air freshening device is provided. The device includes a water-based fragrance emitter including water, a water absorbing polymer and a fragrance composition. The fragrance composition includes from about 3% to about 70% by weight of at least one fragrance ingredient exhibiting a standard equilibrium headspace concentration (HSi0) below about 100 μg/L. The water-based fragrance emitter provides a working signal and an end of life signal upon evaporation. The air freshening device is a warming device.
