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 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 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-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 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 comprises also the invention's core-shell microcapsules as part of a perfuming composition or of a perfuming consumer product.

The present invention relates to water-dispersible core-shell microcapsules essentially free of formaldehyde. In particular it concerns oligomeric compositions comprising, and the microcapsules obtained from, particular reaction product between a polyamine component and a particular mixture of glyoxal and a C2,2-dialkoxy-ethanal. The present invention comprises also the invention's core-shell microcapsules as part of a perfuming composition or of a perfuming consumer product.

Water-dispersible core-shell microcapsules that are essentially free of formaldehyde. Also, oligomeric compositions of, and microcapsules obtained from, particular reaction products between a polyamine component and a particular mixture of glyoxal and a C2,2-dialkoxy-ethanal. These compositions and microcapsules can be used as part of a perfuming composition or of a perfumed consumer product.
