Abstract: A composition comprising a fragrance material consisting of an outer matrix containing components of the fragrance material and disposed within the outer matrix, discrete core particles containing the remaining components of the fragrance material. Components of the fragrance material within the core particles are preferably selected from highly volatile and/or water soluble materials, whereas components of the fragrance material within the outer matrix are preferably selected from relatively low volatile and/or low water soluble materials.

Abstract: The invention relates to microencapsulated fragrance compositions formed by spray drying an oil-in-water emulsion wherein the encapsulating material is a polymeric surfactant, for example polyvinyl alcohol. The encapsulating material contains no additional surfactant material.

Abstract: Description of an inkjet printing method, whereby a second and optionally a third and/or additional ink(s) is/are printed on top of each other or immediately next to each other, whereby (i) the first ink contains a coloring substance precipitable by a precipitation reagent, (ii) the first or the second ink contains the precipitation reagent in temporarily passivated form, and (iii) the first, second or third ink contains an activator for the temporarily passivated precipitation reagent, with the proviso that the temporarily passivated precipitation reagent and the activator are not present in the same ink. The method prevents or reduces the problem of mixing or running into each other of two inks at their border lines. The temporarily passivated precipitation agent can be a complexed multi-valent metal ion, which is displaced from the complex by the activator.
