hydrocolloid (hī´drōkol´oid),

n.pl 1. the materials listed as colloid solids with water; used in dentistry as elastic impression materials. They can be reversible or irreversible.
n.pl 2. an agar-base impression material.
hydrocolloid, irreversible (alginate),
n a type whose physical condition is changed by a chemical action that is not reversible. It is an impression material that is elastic when set. See also alginate.
hydrocolloid, reversible (agar-agar type),
n a type whose physical condition is changed by temperature. The material is made fluid by heat and becomes an elastic solid on cooling.

This dressing is indicated for use on wounds with light to moderate exudate, and - based on its hydrocolloidal properties - forms a gel when it comes into contact with wound fluid to assist in promoting a moist environment conducive to healing.
