The invention relates to mild, aqueous, surfactant preparations for cosmetic purposes and as detergents. These preparations contain, as surfactants, betaines of the general formula ##STR1## in which R is an alkyl group with 7 to 21 carbon atoms, 20 to 100% by weight of the betaines used as R group having an alkyl group with 7 to 9 carbon atoms, in an amount of 1.0 to 40% by weight of the preparation used.
