Oils and fats are truly the classic among impurities. Oily and greasy contaminants can be found in all areas of life. Different ways of dealing with oil and fat contamination exist. Whereas, solvent-based degreasers, on the one hand, are very common in workshops etc., at the same time, aqueous, surfactant-based cleaning agents represent a tried and tested solution for oils and fats. Depending on the application, each type has a perfect right to exist. We rely on both variants, but only on high-quality active ingredients and recipes that meet the highest possible demands for personnel, environment and functional safety. Innovative approaches such as the use of biosurfactants represent no obstacle for us.
