A core-shell microcapsule comprising a core containing a functional ingredient and a shell surrounding or at least partially surrounding said core, the shell comprising a thermosetting resin formed by the reaction of shell-forming monomers comprising a polyamine and a material comprising a plurality of olefinic double bonds capable of reacting with the polyamine.

The present invention relates to the field of delivery systems. More specifically, the invention concerns microcapsules coated with a polysuccinimide derivative and can be used in several industries, in particular in the perfumery industry. Perfuming compositions and perfumed consumer products comprising these microcapsules are also objects of the invention.

There is provided the use of selenide derivatives of fragrance compounds comprising an α,β-unsaturated aldehyde moiety, an α,β-unsaturated ketone moiety, an α,β-unsaturated ester moiety, an α,β-unsaturated lactone moiety or an α,β-unsaturated carboxylic acid moiety in consumer products. There are further provided methods for the synthesis of selenide derivatives, certain selenide derivatives, consumer products comprising the selenide derivatives and methods of perfuming an article or surface using such derivatives.

The present invention relates to the cosmetic use as a skin refreshing agent of the combination of at least one associative nonionic polyether polyurethane and at least one cyclohexanol derivative.

The present invention also relates to a cosmetic method for refreshing the skin, consisting in applying to the skin surface a composition comprising, in particular in a cosmetically acceptable medium: a) an aqueous phase; and b) at least one associative nonionic polyether polyurethane; and c) at least one cyclohexanol derivative.

The present invention also relates to a composition comprising, particularly in a physiologically acceptable medium: a) at least one aqueous phase; and b) at least one associative nonionic polyether polyurethane; and c) at least one cyclohexanol derivative; and d) at least one antiperspirant active agent.

The present invention also relates to a method for the treatment of human perspiration, and optionally of body odors, which consists in applying to the surface of the skin a composition as described previously.

Provided are a novel agent or composition and others.

The agent or composition comprises caryophyllene and is used for at least one selected from the following (purposes) (1) to (3) : (1) promoting relaxation, prolonging a resting-state time, and/or prolonging a motionless time, (2) promoting sleep, and (3) preventing blood pressure elevation.

The present invention also relates to a method for inhaling β-caryophyllene simultaneously with smoking a tobacco product, characterized in that the tobacco product contains a β-caryophyllene-containing seamless capsule in a tobacco filter, wherein the seamless capsule contains an essential oil containing β-caryophyllene as an active ingredient. The applicants found that pulmonary inhalation of β-caryophyllene by the above method allows β-caryophyllene to be efficiently distributed throughout the body, leading to achievements of relaxing and sleep-inducing effects, etc.

The present invention relates to microcapsules with a core-shell or matrix morphology stabilized by cross-linked nanoparticles. A process for the preparation of said microcapsules comprising selecting internal crosslinking of a Pickering emulsion is also an object of the invention. Perfumed consumer products, in particular fine fragrance, home and personal care products are also part of the invention.
