Disclosed are high-porosity protein particles useful for carrying one or more agents of interest, methods for their manufacture and use, and products comprising them.

The present invention relates to a composition comprising a) at least one oil phase, b) at least one aqueous phase, c) at-least one emulsifier, wherein the at-least one emulsifier is any or combination of at-least one emulsifier agent, water with emulsification properties, oil with emulsification properties, and active ingredient with emulsification properties; and d) optionally, one or more biologically active ingredients. The present invention also relates to use of the composition for personal care, pet care, home care, deodorants, pesticides, moisturizers, disinfectants, cleansers, therapeutic devices, topical supplements and/or nutrition. The present invention also relates to a method for preparing such a composition.

An improved process of forming polyurea and chitosan microcapsules encapsulating a benefit agent is described. The process comprises forming a water phase comprising hydrolyzing chitosan in an acidic medium at a pH of 6.5 or less for an extended period and combining with a polyisocyanate. The reaction product of the hydrolyzed chitosan and polyisocyanate yields a microcapsule having improved release characteristics, with enhanced degradation characteristics in OECD test method 301B.

The present invention relates to microparticles having a polymeric shell, and also to aqueous dispersions comprising these microparticles. The microparticles having a polymeric shell comprise: a) at least one acrylic copolymer of HASE type; b) at least one solid/liquid phase change material having a phase transition temperature Tf.sub.1 of greater than or equal to 20° C.; c) at least one solid/liquid phase change material having a phase transition temperature Tf.sub.2 of less than or equal to 30° C., provided that Tf.sub.2 is less than Tf.sub.1; d) optionally at least one active agent.

The present invention relates to novel esters of formula (I) as defined below and their use as fragrance or malodour reducing agents. Moreover, the present invention relates to fragrance compositions comprising a compound or a mixture of compounds of formula (I) and one or more further fragrance substance(s). The invention also provides a method for perfuming a product with a compound or a mixture of compounds of formula (I) as defined below and the perfumed product as well as a method for perfuming hair, skin, textile fibers, surfaces and/or ambient air with a compound or a mixture of compounds of formula (I) as defined below.

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.
