Formula for removing color coats and various soil layers from surfaces, method for producing the agent, and method for cleaning

A method for removing paints and lacquers from surfaces using a cleaning composition, wherein the cleaning composition comprises a microemulsion or a fluid nanophase system comprising the following constituents:

• a) at least one water-insoluble substance with a solubility in water of less than 4 g per litre;
• b) at least one amphiphilic substance, NP-MCA, which has no surfactant structure, is not structure-forming by itself, the solubility of which in water or oil is between 4 g and 1,000 g per litre and which does not accumulate preferentially at the oil-water interface, with the proviso that the NP-MCA is not chosen from 2-ethyl-1,3-hexanediol, 2-methyl-2,4-pentanediol, 2-(n-butyl)-2-ethyl-1,3-propanediol and/or from 1,2-diols;
• c) at least one anionic, cationic, amphoteric and/or nonionic surfactant;
• d) water and/or a water-soluble solvent with hydroxy functionality and, optionally,
• e) auxiliary substances,
• the method comprising:
• applying the cleaning composition to paint or lacquer,
• allowing the cleaning composition applied to the paint or lacquer time to act on the paint or lacquer, and then
• removing the paint or the lacquer treated with the cleaning composition with water.

A method for removing from a surface carbon black, fat, oil, silicone, fine dust, resin or a mixture thereof cosmetic or hair color of colored hair, wherein the cleaning composition comprises a microemulsion or a fluid nanophase system comprising the following constituents:

• a) at least one water-insoluble substance with a solubility in water of less than 4 g per litre;
• b) at least one amphiphilic substance, NP-MCA, which has no surfactant structure, is not structure-forming by itself, the solubility of which in water or oil is between 4 g and 1,000 g per litre and which does not accumulate preferentially at the oil-water interface, with the proviso that the NP-MCA is not chosen from 2-ethyl-1,3-hexanediol, 2-methyl-2,4-pentanediol, 2-(n-butyl)-2-ethyl-1,3-propanediol and/or from 1,2-diols;
• c) at least one anionic, cationic, amphoteric and/or nonionic surfactant;
• d) water and/or a water-soluble solvent with hydroxy functionality and, optionally,
• e) auxiliary substances,
• the method comprising applying the cleaning composition to the carbon black, fat, oil, silicone, fine dust, resin or a mixture thereof, cosmetic or colored hair and removing the cleaning composition and the carbon black, fat, oil, silicone, fine dust, resin or a mixture thereof, cosmetic or coloured hair with water.

A cleaning composition, wherein the cleaning composition contains a microemulsion or a

• fluid nanophase system and comprises the following constituents:
• a) at least one water-insoluble substance with a solubility in water of less than 4 g per litre;
• b) at least one amphiphilic substance, NP-MCA;
• c) at least one anionic, cationic, amphoteric and/or nonionic surfactant;
• d) water and/or a water-soluble solvent with hydroxy functionality and optionally auxiliary substances,
• wherein the NP-MCA is selected from the group consisting of ethyl acetoacetate, isopropyl acetoacetate, methyl acetoacetate, n-butyl acetoacetate, n-propyl acetoacetate and tert-butyl acetoacetate.
