different carbon chain length are suitable for this application a comparison of the investigated potassium salts of fatty acids is given below potassium salt of caprylic acid 8 carbon 10 carbon saturated u02dc 60 caprylic acid u02dc 40 potassium laurate 12 carbon saturated potassium cocoate mixing with the highest proportion of 12 carbon and 14 carbon u02dc 65 saturated potassium oleate 18 carbon unsaturated the aforementioned mixture can be used for cleaning by dipping spraying or application of a thickened composition the composition and the concentration of the constituent components can be controlled for the desired application method and temperature in the case of dipping the microstructure and the phase system can be controlled in order to achieve desirable effects on the environment and the economy for example in the following way the product can be supplied as a concentrate and diluted to produce a solution that is ready to use at the time of application a spent bath can be fractionated phase separated before disposal in order to achieve environmental and cost benefits for example by division into rinsing water can be separated by adjustments of the ph level and or salt content in order to extract water and other mono ethanol amine 10 ml 9 5 paint removal time relative time example 3 example 4.
