Patent ID: 8093197

Claim:
A laundry detergent or cleaner comprising a particulate fluid reservoir, said reservoir comprising a porous, particulate polymer substrate, said polymer comprising a crosslinked polyolefin, a fluoropolymer, or any copolymer or mixture thereof, said substrate having an at least partially open-pore structure with a mean pore diameter of 1 μm to 300 μm and being charged with 5% to 95% by weight, based on the weight of the charged polymer substrate, of an inclusion mixture, said inclusion mixture: a) being highly viscous or solid at temperatures ≦20° C.; b) comprising a fluid and at least one additive that can flow at a temperature of 25° C. to 120° C.; and c) transforming, essentially without decomposition, into a molten state at temperatures below 120° C.
