| 摘要 |
Particles comprising a cross-linked polymeric shell containing a core material comprising a first oil phase are made by forming an oil-in-water dispersion of the core material in an aqueous solution of cross-linkable polymeric material, dispersing this dispersion in a second oil phase to form a water-in-oil dispersion in the second oil phase of particles having a shell of cross-linkable polymeric material and a core comprising the first oil phase, and cross-linking the cross-linkable polymeric material. The process is of particular value for the manufacture of liquid detergents and other compositions containing particles having an active ingredient in the core material. |
