Foam stabilization and oily soil removal with associative thickeners

摘要

The invention involves foam stabilization compositions that rely upon anonionic/hydrophobic interaction. According to the invention, an associative thickener is used to provide long range nonionic/hydrophobic interaction with the hydrophobic groups of the surfactants present in the same. The interaction must be of sufficient character so that the components can maintain long range intermolecular networking, causing longer lasting and increased foam production, even in the presence of hydrophobic/oily soils. The system provides an environmentally friendly alternative for traditional foaming enhancers such as cocamide DEA.

1. A foaming cleaning composition comprising:
an associative thickener polymer; a detersive amount of a surfactant comprising a sorbitan ester and/or an ethoxylated sorbitan ester nonionic surfactant; an amphoteric surfactant, wherein the amphoteric surfactant is an amine oxide in an amount less than about 8 wt. % actives, or a betaine or sultaine in an amount between about 10 wt. % and about 75 wt. %; and wherein said composition has less than 0.5 wt. DEA of cocamide DEA.
