The core of the particles comprises a perfume and the shell (which preferably comprises an aminoplast polymer) also comprises a non-ionic deposition aid (such as locust bean gum) which is substantive to textiles. The process of the invention is characterised in that, during the emulsion polymerisation step, the solids content of the polymerisation mixture does not fall below 25% wt. The particles obtained by the process are suitable for inclusion in laundry products and show significantly improved deposition and retention onto fabrics being laundered as compared with particles formed at lower solids levels.
