Claims19
A protected enzyme system consisting essentially of a hydrophobic fluid which is substantially insoluble in aqueous liquid laundry detergents and a detergent enzyme dispersed in said fluid.
A protected enzyme system consisting essentially of enzyme containing granules coated with a fluid hydrocarbon.
A fluid cleaning composition consisting essentially of water, surfactant and a dispersed detergent enzyme said enzyme being protected from said composition by a hydrophobic fluid which is substantially insoluble in said composition.
A cleaning composition having dispersed therein a protected enzyme system which system consists essentially of particles of detergent enzyme dispersed in a hydrophobic fluid having a viscosity of from 0.05 to 200 Pascal seconds.
