Zusammenfassung:Oil-in-water (O/W) emulsion (I) containing (a) hydrophobically-modified polysaccharide(s), (b) copolymer(s) based on acrylamidoalkanoic acids, (c) fatty material(s) and (d) water, shows a viscosity (at 25[deg] C and 1 bar) of 100-1000 mPa.s at a shear rate of 1 Hz and a viscosity of 0.1-10 mPa.s at a shear rate of 100 Hz. Independent claims are included for (1) O/W emulsions with the above viscosity properties which also contain surfactants, emulsifiers and coemulsifiers with a molecular weight of less than 1000 g/mol in an amount of less than 0.2 wt.% (2) a method for dyeing, toning or bleaching hair by applying (I) to the scalp .
