I was looking up the ingredients and found this little bit which seemed interesting in something to do with alkaline builders
Wetting agents (surfactants and synthetic detergents) aid in removing contaminants by lowering the surface tension of the solution, allowing the cleaner to get under the contaminant and displace it from the metal surface. Once the contaminant is in solution, the wetting agent creates an emulsion, preventing redeposition onto the part being cleaned. Surfactants have one end that is soluble in water (hydrophilic) and one end that is soluble in oil (hydrophobic). This allows the surfactant molecule to create an oil-water emulsion that is easily rinsed away. Cleaning principles. Soil is defined as matter out of place. Regardless of the type or category, all cleaners remove contaminants from a substrate by one or more of the following principles:
* solvent action - enables the cleaner to dissolve oils present on the metal surface;
* saponification - chemically converts drawing compounds (organic oils and fatty acids) into water-soluble soaps that can add to cleaning efficiency;
* detergency - surface active agents, or surfactants, reduce the interfacial tension between solution and contaminant, enabling cleaning solutions to better penetrate and displace contaminants from the metal surface;
* emulsification - surfactants in the cleaning solution suspend contaminants in the aqueous phase for easy rinsing; and
* deflocculation - disperses contaminants into very fine particles that are suspended in the cleaning solution. Materials to be removed are classified into two general
I wish I hadn't forgotten tim told me about this stuff
