Abstract

Compositions than contain from about 1% to about 80% by weight of surfactants selected from the group consisting of nonionic, anionic, cationic, amphoteric or zwitteronic surfactants, or mixtures thereof; and from about 0.1% to about 10%, by weight of a mixture of amino acid based polymers, oligomers or copolymers of the general formula (I) wherein the polymer, oligomer, or copolymer contains at least about 5 mole % of one or more amino acids and an organic acid are disclosed. The compositions are useful as fabric treatment agents as they can impart fabric appearance and integrity benefits to fabrics.
