FOAM STABILIZATION WITH POLYETHYLENEIMINE ETHOXYLATES

摘要

The invention involves foam stabilization compositions that rely upon an electrostatic charge interaction. According to the invention, the positively charged class of polymers such as polyethyleneimine (PEI) polymers are used to provide a long range electrostatic interaction with detersive anionic or amphoteric surfactants present in the same. The interaction must be of sufficient character so that the components do not precipitate out, instead causing longer lasting and increased foam production. The system provides an environmentally friendly alternative for traditional foaming enhancers such as cocamide DEA.
