<p>Detergent compositions containing self-requestering surfactants the molecules of which contain both a hydrophilic structure and a lipophilic structure are disclosed. The compositions comprise at least 5% by weight, of hydrosoluble salts having the formula in which R is alkyl, arylalkyl or alkylaryl of from 6 to 18 carbon atoms: at least one of the groups represented by Z is a -CH2-COO-Me+ carboxymethylene group in which Me+ represents an ion selected from sodium, potassium and ammonium ions and from quaternary onium cations, and combinations thereof, and the remaining Z groups, which may be the same or different, represent H or a carboxymethylene as defined above.</p> |
