Abstract: The present invention relates to a process for obtaining an encapsulated composition, to an encapsulated composition obtainable by this process, to products comprising these encapsulated compositions and to a use of these encapsulated compositions for obtaining a consumer product.

Abstract: A method of covalently bonding a modifier to a polymeric microcapsule wall, which wall comprises entities capable of reaction with acrylic moieties, comprising the provision on the wall of a linking compound to which the modifier is subsequently attached, the linking compound having the Formula I in which n=1 to 30; R1, R2 and R3 are independently selected from the following moieties: R1 and R3 are H and Me; and X is selected from O and NH; and R2 is selected from CH2, CH2CH(OH)CH2, and CH2,CH2. Microcapsuies thus modified exhibit enhanced substantivity to substrates such as textiles when used in laundry preparations.

Abstract: Disclosed is an encapsulated composition comprising at least one perfume and/or cosmetic ingredient that is entrapped in a matrix. The matrix comprises a starch and a hemicellulose.

Abstract: This invention relates to a process for the continuous production of a (meth)acrylic ester by transesterification reaction between a C1-C4 light alkyl (meth)acrylate, with a heavy alcohol in the presence of a catalyst, characterised in that the flows feeding the reactor are introduced through a static mixer placed on a recirculation loop of the reactor. The use of a static mixer improves the selectivity of the reaction and consequently the overall productivity of (meth)acrylic ester synthesis process.

Abstract: The invention relates to the use of 2,6,-di-tert-butyl-4-methylphenol at a moiety of 25 to 200 ppm for stabilizing N,N-dimethylaminoethyl acrylate in respect of discoloring effects. The invention also relates to an N,N-dimethylaminoethyl acrylate stabilized in said manner and to a method for producing the same.

Abstract: The invention relates to a method for producing a (meth)acrylic ester with improved productivity, by transesterfication of a light alkyl (meth)acrylate with a heavy alcohol. The method of the invention includes the recycling of noble products recovered after the thermal treatment of heavy fractions generated during the synthesis, said thermal treatment being carried out in the presence of a dialkyl phthalate, the alkyl chain of which corresponds to that of the light alkyl (meth)acrylate. The invention applies to the production of N,N-dimethyaminoethyl acrylate from ethyl acrylate.
