A method of providing a modifier on the surface of an active-containing core-shell aminoplast microcapsule, including the covalent attachment of the modifier to the capsule shell surface by means of a coupling compound capable of covalent bonding to both shell and modifier by means of epoxy groups on the coupling compound. The method is especially useful for enhancing the substantiveness to fabrics of fragrance microcapsules added to laundry products.

Surface modification of microcapsules

Approaches are described for coating various flexible media, such as sheets of paper, synthetic polymer (polyolefin, polyester, etc.) sheets or fabric sheets, with a silicone on high-speed rolls. For example, an efficient method is described for minimizing and/or reducing mist formation when coating flexible supports with a liquid silicone composition precursor of crosslinked coatings. The coating process can be performed using a coating device that includes a roll operating at a high speed.
