Matrix or core shell enzyme capsule compositions comprising defined density modifying solids surrounded by defined core structurant material

A matrix or core-shell capsule composition comprising:

• (a) 0.1-25% of a component subject to degradation by components in an aqueous liquid composition, wherein said component subject to degradation is selected from the group consisting of enzymes, bleach catalysts, peracid bleaches, bleach activators and optical brighteners;
• (b) 0.1-30% by wt. of a mineral-type solid or water soluble salt solid that are chemically non-reactive with other detergent components and have a particle size of 5 .mu.m to 100 .mu.m;
• (c) 1.0-80% of a hydrophobic polymer core encompassing components (a) and (b) comprising hydrophobic polymer having melting temperature of 40.degree.-85.degree. C. in combination with an oil having a viscosity of 10-100 centipoise and specific gravity of 0.7-1.2, wherein the ratio of polymer to oil is 0.2 to 2.0;
• (d) a core diluent comprising a hydrocarbon oil having a viscosity such that when mixed with components (a), (b) and (c) at less than 60% of final capsule composition, the viscosity of (a)-(d) combined is less than 10,000 mPas measured at a shear rate of 100s.sup.-1 and above;
• and
• (e) 0.1 to 50% a polymer shell surrounding a mixture of said core (c) and diluent (d) wherein said shell is a water soluble or water dispersible polymer selected from the group consisting of polyvinyl alcohol, a polyvinylamide, polyvinyl pyrrolidone, carrageenan, guar gum, xanthan gum, cellulose and protein.
