1. A cosmetic composition, comprising:
- a particulate fluid 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 μ
m to 300 μ
m 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 of ≦
20°
C.;
b) comprising a fluid and at least one additive that can flow at a temperature of 25°
C. to 120°
C., wherein the fluid further comprises one or more skin-care and/or skin-protective active substances;
c) transforming, essentially without decomposition, into a molten state at temperatures below 120°
C.; and
d) further comprising a solid selected from the group consisting of zeolite, bentonite, silicate, phosphate, urea, urea derivative, sulfate, carbonate, citrate, citric acid, acetate, anionic surfactant salt, and mixtures thereof.

Abstract
Fluid reservoirs which are based on polymer substrates and are capable of storing large amounts of fluids. The storage is reliable and the reemergence from the liquid reservoir is readily controllable, for example, via the temperature or via mechanical actions, to achieve retardation of the fluid release. Also, processes for producing such fluid reservoirs and also their use, for example in washing or cleaning compositions.
