| The surfactants include fluroethers, oligomers of propylene-oxide, siloxanes, etc. |
| Research on surfactants and membrane solubilization showed that anionic surfactants interact more with lipid bilayers. |
| In 1937 the first cationic surfactants were used in bituminous road construction and these were quaternary ammonium salts. |
| Their activity may be enhanced by using membrane-disrupting surfactants such as quaternary ammonium compounds. |
| Sometimes surfactants are mixed into solvent sealers so that the residue will mix with water for easier cleanup afterwards. |
| Non-ionic surfactants act as accelerators of diffusion in the cuticular wax barrier. |
