Definitions

  • fragrances are essential oils, resinoids and resins from a variety of sources such as: B. Peru balsam, olibanum resinidid, ⁇ tyrax, labdanum resin, nutmeg, cassia oil, benzoin resin, coriander and lavandin.
  • suitable fragrances are: phenyl ethyl alcohol, terpineol, linalool, linalyl acetate, geraniol, nerol, 2- (1, l-dimethylethyl) cyclohexanol acetate, benzyl acetate and eugenol.
  • the core of the microcapsules is formed by the water-emulsifiable hydrophobic material.
  • the hydrophobic material also serves as a solvent or dispersant for the monomer mixture used in the manufacture of the capsule shells by polymerization.
  • the polymerization then takes place in the oil phase of a stable oil-in-water emulsion.
  • This emulsion is obtained by, for example, first dissolving the monomers and a polymerization initiator and, if appropriate, a polymerization regulator in the hydrophobic material and emulsifying the solution thus obtained in an aqueous medium with an emulsifier and / or protective colloid.
  • grafted degraded or degraded reduced starches and grafted polyethylene oxides are preferably used, 20 to 80% by weight of monomers, based on the graft component, being used in the graft polymerization.
  • a mixture of maleic acid and acrylic acid in a weight ratio of 90:10 to 10:90 is preferably used for the grafting.
  • organic cobuilders are polyaspartic acid or cocondensates of aspartic acid with further amino acids, C 4 -C 25 mono- or dicarboxylic acids and / or C 4 -C 25 mono- or diamines.
  • Polyaspartic acids modified with C 6 -C 22 mono- or dicarboxylic acids or with C 6 -C mono- or diamines are particularly preferably prepared in acids containing phosphorus.
  • microcapsules according to the invention 0.001 to 2% by weight, preferably 0.01 to 0.5% by weight of microcapsules according to the invention
  • the agents are usually marketed in the form of aqueous concentrates which are used undiluted or diluted.

Abstract

La présente invention concerne des préparations de microcapsules, contenant des microcapsules qui présentent un noyau, constitué d'un matériau hydrophobe comprenant au moins une matière odorante, ainsi qu'une enveloppe, obtenue soit i) par polymérisation radicalaire de monomères éthyléniquement insaturés, qui comprennent 30 à 100 % en poids d'un ou plusieurs esters d'alkyle C1-C24 d'acide acrylique et/ou méthacrylique, 0 à 70 % en poids d'un monomère bifonctionnel ou polyfonctionnel, 0 à 40 % en poids d'autres monomères, soit ii) par condensation, induite par acide, de précondensats de mélamine-formaldéhyde et/ou de leur éthers d'alkyle C1-C4. La présente invention concerne également des compositions de produit détergent ou de produit nettoyant, qui contiennent lesdites microcapsules.
