A personal care composition, comprising: a combination of surfactants, comprising at least two of ammonium laureth sulfate, sodium laureth sulfate, and cocamidopropyl betaine; and at least one derivatized quaternized hydroxyethyl cellulose ether, selected such that the quaternized cellulose ether comprises fewer than 4000 anhydroglucose repeat units, an average substitution level of hydrophobic substituents, comprising an alkyl, alkylaryl or arylalkyl group having 8 to 30 carbon atoms, from about 0.005 to about 0.3 moles of substituent per mole of anhydroglucose unit, a nitrogen percentage from about 0.3 to about 3.0, provided that the average substitution level of hydrophobic substituents is less than the average substitution level of cationic substituents; and with the proviso that the personal care composition does not contain methyl glucose dioleate.
