摘要:
The present invention relates to water-dispersable microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile α-ketoacid or α-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.

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 C4-6 2,2-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.

Disclosed herein is a core-shell microcapsule slurry including at least one core-shell microcapsule. The at least one core-shell microcapsule includes an oil-based core including a hydrophobic material, a polymeric shell and a coating having a first deposition aid, and a second deposition aid. Further disclosed herein are a perfumed consumer product and a method for preparing the same.
摘要:
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.
摘要:
The present invention relates to water-dispersable microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile polymer comprising α-ketoacid or α-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.
摘要:
The present invention relates to the field of perfumery. More particularly, it concerns polymers derived from siloxane derivatives and comprising at least one β-thio carbonyl moiety capable of liberating an active molecule such as, for example, an α,β-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.
