Described herein is a fragrance delivery system including a perfume oil and a carrier material, where the perfume oil includes at least one pro-perfume compound and where the perfume oil is dispersed in or absorbed within the carrier material. Also described herein are compositions and perfumed products including the same.

Encapsulated pro-perfume compounds

Described herein are microcapsules having an oil-based core and a polymeric shell, where the oil-based core includes a perfume oil having high impact perfume raw materials and a density balancing material. Perfuming compositions and consumer products including said microcapsules, in particular isotropic or structured consumer products in the form of home care or personal care products, are also described herein.

Density balanced high impact perfume microcapsules

The present invention relates to the field of perfumery. More particularly, it concerns polymers derived from siloxane derivatives and comprising at least one &#x3b2;-thio carbonyl moiety capable of liberating an active molecule such as, for example, an &#x3b1;,&#x3b2;-unsaturated ketone or aldehyde. The present invention concerns also the use of polymers in perfumery as part of a perfuming or malodor counteracting composition as well as the perfuming compositions or perfumed articles comprising the invention's compounds.

Polysiloxane conjugates as fragrance delivery systems

The present invention relates to a process for producing microcapsules with a polyurea wall, as well as to the microcapsules themselves and consumer products comprising these microcapsules. The process of the invention uses 3,5-diamino-1,2,4-triazole as a specific polyamine for forming the wall with the polyisocyanate.

Process for preparing polyurea microcapsules

The present invention relates to a process for producing perfume-containing microcapsules with a polyurea wall that can be used in home or personal care products, as well as to the microcapsules themselves and consumer products that include or incorporate these microcapsules. The process of the invention uses a particular colloidal stabilizer in the form of an aqueous solution that includes defined proportions of particular polymers.
