摘要： A process for the production of 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 a diameter less than 30 .mu.m, comprising emulsifying an enzyme composition into a water immiscible liquid in the presence of a polymeric dispersion stabilizer to form a stable dispersion of aqueous enzyme particles having a dry size below 30 .mu.m dispersed in the liquid, and dehydrating the dispersed particles by azeotropic distillation, wherein before, during or after dehydrating the particles the process comprises adding an organic liquid which is less volatile than the water immiscible liquid and which is selected from surfactants and water miscible liquids to the dispersion and distilling the water immiscible liquid 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.

摘要： A polymeric amphipathic stabiliser is formed of hydrophobic monomer units and hydrophilic monomer units which comprise carboxylic free acid or acid salt units and glycidyl or anhydride units. The glycidyl or anhydride units react onto reactive groups on polymer particles when dispersed in non-aqueous liquid and provide improved stability when the particles are subsequently dispersed in liquid electrolyte.

The particles have a polymer shell formed from a condensation polymer which is permeable to water and low molecular weight components of the outer liquid phase and the core comprises the enzyme, an inner liquid detergent phase in substantially equilibrium with the outer phase and a core polymer which causes stretching as a result of osmosis when the concentrate is diluted in water. Encapsulated precipitated enzymes are also disclosed.
