1. A sprayable cleaning composition comprising:
from about 0.0035 wt. % to about 1 wt. % of an alkali soluble emulsion polymer, wherein the alkali soluble emulsion polymer is in an emulsion where the continuous phase is water or a water miscible liquid; wherein the alkali soluble emulsion polymer is stable at a pH of at least about 10;
an alkalinity source, wherein the alkalinity source is in a concentration sufficient to neutralize the alkali soluble emulsion polymer;
from about 0.1 wt. % to about 10 wt. % of a foaming agent; wherein the foaming agent comprises an anionic surfactant, a nonionic surfactant, an amphoteric surfactant, or a combination thereof wherein the composition is free of cationic surfactant; and
water;
wherein the sprayable cleaning composition reduces the formation of airborne aerosol particles having a micron size of less than about 10 when sprayed, and a use solution of the composition has a shear viscosity from about 1 to about 500 cPs.
