Abstract:
1. A method for cleaning objects made of organic or inorganic materials comprising the steps of: A) bringing an object made of organic or inorganic materials into contact with a composition in the form of a fluid nanophase system comprising the components a) at least one water-insoluble substance with a water solubility of less than 4 grams per liter, in a quantity of from 0.1 to 90 wt.-%, b) at least one mixed-chain amphiphilic substance NP-MCA, which does not have a surfactant structure and is not micelle-structure-forming on its own, which has a solubility in water or oil that is between 4 g and 1000 g per liter and which does not accumulate at an oil-water interface, in a quantity of from 0.1 to 80 wt.-%, c) at least one anionic, cationic, amphoteric and/or non-ionic surfactant; in a quantity of from 0.1 to 45 wt.-%, d) water in a quantity of between 1.0 and 90 wt.-%, e) optionally one or more excipients, in a quantity of from 0.01 to 10 wt.-%, wherein each percentage is based on a total weight of the composition, and wherein the NP-MCA is selected from acetoacetates of Formula II: wherein in each case independently of each other R3 is hydrogen or a C1 to C2 alkyl and R4 is a branched or unbranched C1 to C4 alkyl; or acetoacetates of Formula III: wherein R5 is a C1 to C4 alkyl; B) leaving the composition from step A) in contact with the object until gas or gas bubbles form on the object, C) removing the composition from step A) from the object and D) optionally then rinsing and/or drying the object treated by steps A) and B).
