Abstract (en)
[origin: EP0866115A2] The invention relates to compositions for cleaning hard surfaces, wherein said composition comprises both cleans the surface and prevents or retards further soiling of the surface and provides an aqueous, hard-surface cleaning composition comprising a surfactant mixture, wherein said surfactant mixture comprises: a) a cationic fluorosurfactant, and, b) a non-fluorinated nonionic surfactant. It is believed that the cationic fluorosurfactants present in the compositions of the present invention modify the surface energy of surfaces to which the composition is applied so as to raise the contact angle of soil subsequently deposited on the modified surface. Suitable fluorosurfactant compounds can be broadly described as compounds which contain at least one CF3 moiety and a group carrying a positive charge. Preferably, the fluorosurfactants employed in the present invention are of the general formula: <MATH> wherein L is a linking group which is preferably selected from linear or branched aliphatic or fluoro-aliphatic chains which may contain heteroatoms and R1, R2, and R3 are preferably short chain alkyl groups, typically C1-C5 alkyl groups of which methyl groups are preferred: in an alternative, one of R1, R2 or R3 is itself a moiety of the form CF3-L-.
