Abstract

L'invention concerne des mélanges de sulfonates d'alpha-oléfine C¿8? à C¿22? et de sulfates d'éther alcoylique représentés par la formule: RO-(CH¿2?CH¿2?O)¿1-4?SO¿3?Na. Dans cette formule, R est alkyle C¿8?-C¿18?, avec un ou plusieurs alcoxylates d'alcool C¿1?-C¿10?, des dialkoxylates de certains diacides de cyclohexényle, ou des composés d'ammonium quaternaire propoxylés. L'invention concerne également des mélanges d'alcoxylates d'acide gras, d'alcoxylates d'alcool gras et d'un ou de plusieurs dialcoxylates de diacide de cyclohexényle et alcoxylates d'alcool C¿1?-c¿10?. Tous ces mélanges améliorent l'élimination de l'encre lorsqu'ils sont utilisés pour le désencrage en flottation par mousse des vieux papiers.
