Abstract

A foaming composition is described which is capable of forming foams that are particularly appropriate for reducing or weakening the pressure associated with the shock wave generated by a burst, comprising particular surface-active agents and, in order to increase the duration and multiplicity of use thereof, either polymers, or proteins, or polymers and proteins.
