STABLE FOAM AND PROCESS FOR ITS MANUFACTURE

摘要

A stable foam of a liquid matrix, gas bubbles and a structuring agent that forms a lamellar or vesicular cage structure without generating a gel imparting a rubbery texture to the foam. The lamellar cage structure entraps at least a substantial portion of the gas bubbles and liquid matrix therein to retain and stabilize the gas bubbles and liquid in a sufficiently compact structure that substantially prevents drainage of the liquid matrix as well as coalescence and creaming of the gas bubbles to maintain stability of the foam even when the foam is subjected to multiple heat shocks.
