<p>There is provided a process for the production of novel, stable fluid enzyme dispersions having a content of at least 0.5 % by weight enzyme, in which the enzyme is present in the form of anhydrous particles of diameter less than 30νm, comprising emulsifying an enzyme composition into water immiscible liquid in the presence of a polymeric dispersion stabiliser to form a stable dispersion of aqueous enzyme particles having a dry size below 30νm dispersed in the liquid, and dehydrating the dispersed particles by azeotropic distillation, characterised in that before, during or after dehydrating the particles an organic liquid which is less volatile than the water immiscible liquid and which is selected from surfactants and water miscible liquids is added to the dispersion and the water immiscible liquid is distilled from the dispersion until the amount of the initial water immiscible liquid remaining in the dispersion is below 20 % by weight of the liquid phase in the dispersion. These novel dispersions may be incorporated into liquid enzyme-containing compositions, in particular liquid detergent compositions.</p> |
