Abstract:
A mobile liquid surfactant blend having a viscosity at 65.degree. C., measured at a shear rate of 50 s.sup.-1, not exceeding 1 Pas, and having a critical temperature T.sub.c below which the viscosity at 50 s.sup.-1 exceeds 1 Pas not exceeding 50.degree. C., the blend consisting essentially of(i) from 20 to 60 wt % of an alkylpolyglycoside,(ii) from of an ethoxylated nonionic surfactant, and(iii) water,the weight ratio of the alkylpolyglycoside to the ethoxylated nonionic surfactant being from 35:65 to 65:35 and the weight ratio of the ethoxylated nonionic surfactant to water being within the range of from 90:10 to 60:40.
