  • Patent number: 8426353
    Abstract: The present invention relates to a process for producing perfume-containing microcapsules with a polyurea wall that can be used in home or personal care products, as well as to the microcapsules themselves and consumer products that include or incorporate these microcapsules. The process of the invention uses a particular colloidal stabilizer in the form of an aqueous solution that includes defined proportions of particular polymers.

  • Patent number: 6939835
    Abstract: Compounds of the formula in which the dotted lines indicate the position of single or double bonds, R1 represents a radical belonging to a fragrant alcohol of the formula R1OH, X represents a nucleophilic group selected from the group consisting of —OH, ?O, —NH2 or —NHR3, R3 representing a C1 to C6 straight-chain or branched hydrocarbon radical, saturated or unsaturated, or an aliphatic or aromatic ring having 5 or 6 carbon atoms, m and n define whole numbers within the range 0 to 2 such that the sum m+n is equal to 1 or 2, p defines a whole number with a value of 0 or 1, each of the symbols R2, R4, R5, R6, R7, taken independently, represents a hydrogen atom, a C1 to C4 straight-chain or branched hydrocarbon radical, saturated or unsaturated, optionally substituted and, taken two by two, they can form aromatic or aliphatic monocyclic, bicyclic or tricyclic substances with the carbon atoms to which they are bound, are compounds capable of releasing a fragrant alcohol of the formula R1OH upon hydrolysis of
