Supercritical fluid (SCF) is used to scour a target material to leave scour elements, such as oligomers and oils from the target material. Carbon dioxide (CO.sub.2) is introduced into a pressure vessel also containing the target material to be scoured. The CO.sub.2 is raised in temperature and pressure to a SCF state. The CO.sub.2 is recirculated within the pressure vessel to scour the target material. An exchange of the CO.sub.2 is occurs allowing for the scoured elements to be removed from the CO.sub.2 and therefore from within the pressure vessel. Operation variables such as temperature, pressure, time, internal flow rate, and CO.sub.2 exchange are adjusted to achieve a scouring of the target material.

A composition including a plurality of particles. The particles include from about 40% to about 99% by weight of said particles of a carrier and from about 0.0001% to about 5% by weight of an enzyme. Each of the particles has a mass between about 1 mg to about 5000 mg.

Provided is a detergent having a high detergency against corneum-derived stains and a method for evaluating the ability of an enzyme to degrade corneum-derived stains. The detergent a M23A subfamily protease as an active ingredient. The method for evaluating the ability of the enzyme to degrade corneum-derived stains comprises obtaining the degrading activities of the test enzyme on a reference peptide and one or more substrate peptides and evaluating the ability of the test enzyme to degrade corneum-derived stains based on the degrading activities of the test enzyme on the reference peptide and the substrate peptide, wherein the reference peptide is GGGGG or GGGG, the one or more substrate peptides are selected from the group consisting of GGGXG, GXGGG, GGXG, and GXGG, and X is any amino acid residue other than glycine.

The invention provides a cleaning formulation comprising a multiplicity of solid cleaning particles, wherein the solid cleaning particles comprise polymeric particles and at least one cleaning agent, wherein the at least one cleaning agent is immobilised on the surface of the polymeric particles. Typically the at least one cleaning agent is immobilised on the surface of the polymeric particles by means of chemical bonds, typically ionic bonds, hydrogen bonds, covalent bonds, polar bonds, or bonds formed by virtue of unequal charge distributions between polymeric particles and immobilised materials. The invention also provides a method for the cleaning of a substrate, the method comprising the treatment of the substrate with a formulation according to the invention, and a method for the preparation of the cleaning formulation of the invention which comprises treating a multiplicity of polymeric particles with at least one cleaning agent.
