We report the influence of adding five short‐chain glycol ethers (SCGEs) on the structure, stability, and viscoelastic properties of aqueous dispersions of partially hydrolyzed poly(vinyl acetate) and borax. The properties of these gel‐like materials have been investigated as a function of the structure of the added SCGE both below and above the critical aggregation (or micellar) concentrations using 11 B and 13 C NMR, rheology, and small‐angle neutron scattering. The results indicate that the SCGE aggregation behavior is not affected by incorporation into the gel‐like network. However, changes in the viscoelasticity and structural properties of the dispersions were detected that can be correlated to the nature of the solvent system. Also, the ability of these materials to clean an unvarnished acrylic paint surface coated with synthetic soil has been evaluated using colorimetery, and the surface of the dispersion after cleaning was visualized with scanning electron microscopy.
