Abstract
An indicator composition can be used to detect various environmental conditions stimuli such as in sterilization or storage processes. This indicator composition has a) a first polymeric particle comprising a solid continuous polymeric phase and a first reactant, the first polymeric particle having a mode particle size equal to or less than 50 μm; and b) a second reactant outside of the first polymeric particle, which second reactant is capable of reacting with the first reactant when exposed to a chosen environmental condition stimulus. The indicator composition can be used by exposing it to the environmental condition stimulus for a sufficient time to cause a detectable change in the indicator composition such as a detectable color change.
