摘要： Described herein is a liquid phosphate-free detergent composition including (A) at least two chelating agents, (A1) one being selected from alkali metal salts of MGDA and GLDA, (A2) one being selected from alkali metal salts of citric acid, (B) at least one anionic surfactant according to general formula (I): CnH2n+1—O(CH2CH2O)x—SO3M, (C) at least two non-ionic surfactants, (C1) one being selected from alkyl polyglycosides, (C2) and at least one further non-ionic surfactant, the weight ratio of all chelating agent (A) to all anionic surfactant (B) being in the range of from 1:7 to 1:2.5, wherein where: n is a number in the range of from 10 to 18, M is selected from alkali metals, x is a number in the range of from 1 to 5, wherein where said detergent composition has a non-volatile content in the range of from 10 to 30% by weight.

摘要： Process for cleaning hard surfaces, characterized in that said process is carried out using a foam based on a formulation comprising: (A) at least one complexing agent selected from the alkali metal salts of aminocarboxylic acids and from alkali metal salts of citric acid, gluconic acid, tartaric acid and lactic acid, (B) at least one non-ionic surfactant of general formula (I): (G)x-OR1, (C) at least one anionic surfactant, (D) at least one zwitterionic surfactant, wherein: R1 is selected from C8-C18-alkyl, straight chain or branched, x is in the range of from 1.1 to 4, G selected from monosaccharides with 4 to 6 carbon atoms.
