Described herein is a process for a preparation of microcapsules based on cleavable multi-alcohols. Also described herein are cleavable multi-alcohol-based microcapsules. Also described herein are perfuming compositions and consumer products including such capsules, in particular perfumed consumer products in the form of home care or personal care products.

Cleavable multi-alcohol-based microcapsules

Described herein is a new process for the preparation of polysuccinimide derivatives-based core-shell microcapsules. Also described are microcapsules, as well as perfuming compositions and consumer products including these microcapsules, in particular perfumed consumer products in the form of home care or personal care products.

Process for preparing polysuccinimide derivatives-based microcapsules

The present invention relates to a new process for the preparation of melamine-formaldehyde free microcapsules. Microcapsules obtainable by said process are also an object of the invention. Perfuming compositions and consumer products comprising said capsules, in particular perfumed consumer products in the form of home care or personal care products, are also part of the invention.

Process for the preparation of microcapsules

The present invention relates to water-dispersible microcapsules that include an oil phase, e.g. a perfume, containing a photolabile compound capable of generating a gas upon exposure to light. The gas is able to cause an extension or the breaking of the microcapsule allowing the release of the oil phase and thus increasing the long-lastingness of the odor perception. The present invention concerns also the use of such microcapsules in perfumery as well as the perfuming compositions or perfumed articles that include such microcapsules therein to provide a prolonged release of fragrant molecules.

Microcapsules containing a gas-releasing photolabile compound and uses thereof

The invention relates to microcapsules coated by a particular mixture of copolymers, which demonstrate a high rate of deposition when applied on a substrate. Those microcapsules can be used in several industries, in particular in perfumery and rinse-off applications. Perfuming compositions and perfumed consumer products comprising these microcapsules are also objects of the invention.

Delivery system with improved deposition

The present invention relates to a process for producing perfume-containing microcapsules with improved olfactive performance by using at least one aromatic polyisocyanate with a specific mixture of polyamines. Microcapsules obtainable by such a process and perfuming compositions or the consumer products comprising these microcapsules are also objects of the invention. In particular, the microcapsules can be used in home or personal care products.

Process for preparing polyurea microcapsules

The present invention relates to the field of perfumery. More particularly, it concerns co-polymers, derived from aspartic acid and comprising at least one &#x3b1;- or &#x3b2;-aspartic acid derivative 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 or co-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.

Poly(aspartic acid) derived co-polymers for a controlled release of perfuming ingredients

The present invention relates to microcapsules delivering long lasting and intense vanilla-based odor note. More particularly, the present invention concerns a microcapsule comprising between 10% and 30% by weight, relative to the total weight of the microcapsule, of a particular perfuming ingredient imparting a vanilla-based odor note, which can be used in perfuming compositions and perfuming consumer products.

Microcapsules imparting intense vanilla odor note

The present invention relates to water-dispersable microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile polymer comprising &#x3b1;-ketoacid or &#x3b1;-ketoester group capable of generating a gas upon exposure to light. The gas is able to cause an extension or the breaking of the microcapsule allowing the release of the oil phase and thus increasing the long-lastingness of the odor perception. The present invention concerns also the use of said microcapsules in perfumery as well as perfuming compositions or perfumed articles comprising the invention's microcapsules to provide a prolonged release of fragrant molecules.

Microcapsules containing a gas-generating photolabile polymer and uses thereof

The present invention relates to water-dispersible core-shell microcapsules essentially free of formaldehyde. In particular it concerns core-shell microcapsules having a shell obtained by reacting polyisocyanates or polyoxirans cross-linkers and oligomeric compositions which are the reaction products between a polyamine component and a particular mixture of glyoxal and a C2,2-dialkoxy-ethanal. The present invention also utilizes the invention's core-shell microcapsules as part of a perfuming composition or of a perfuming consumer product.

Stable formaldehyde-free 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.

Polysiloxanes as fragrance delivery systems in fine perfumery

Polysiloxane conjugates as fragrance delivery systems

The present invention relates to water-dispersable microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile &#x3b1;-ketoacid or &#x3b1;-ketoester capable of generating a gas upon exposure to light. The gas is able to cause an extension or the breaking of the microcapsule allowing the release of the oil phase and thus increasing the long-lastingness of the odor perception. The present invention concerns also the use of said microcapsules in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's microcapsules to provide a prolonged release of fragrant molecules.

Microcapsules containing a gas-generating photolabile ketoacid or ketoester and uses thereof

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.

The present invention relates to the field of perfumery. More particularly, it provides a perfuming composition capable of prolonging the release of a perfuming component into the surrounding environment when applied on a body surface. The composition comprises PPG-3 myristyl ether as a fragrance evaporation modulator in the presence of high amounts of ethanol. The invention also relates to consumer articles containing such compositions. It finally provides methods for the perfuming of a body surface and a method for increasing the long-lastingness of a perfuming component using these compositions.
