The invention provides aqueous concentrates comprising, based on the total composition,n A) 0.1 to 8.0% by weight, preferably 3.0 to 7.0% by weight, of one or more isethionates of formula (1) nn RCOOCH 2 CH 2 SO 3 M (1) n in whichn R is a linear or branched alkyl group or alkenyl group and M is a counterion, B) 0.1 to 8.0% by weight of one or more taurates of formula (2) nn R 1 CON(CH 3 )CH 2 CH 2 SO 3 X (2) n in which R 1 and X have the same meaning as R and M andn C) 0.1 to 40.0% by weight of one or more alkylbetaines of formula (3) nn n n n n n n n n n in which R 2 has the same meaning as R, with the proviso that the concentration of the sum of all surfactants with the formula 1, 2 and 3 is more than 20% by weight. n These concentrates are flowable at room temperature and are transparent and also colorless. |
