CA 2298537

Compositions that contain from about 1 % to about 80 % by weight of surfactants selected from the group consisting of nonionic, anionic, cationic, amphoteric, or zwitterionic 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 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. These of amino acid based polymers, oligomers or copolymers can be obtained by condensing a basic amino acid, such as lysine, with an organic acid. The amino acid based polymer, oligomer or copolymer materials are useful as fabric treatment agents as they can impart fabric appearance and integrity benefits to fabrics and textiles laundered in washing solutions which contain such materials.

La présente invention concerne des compositions contenant: de 1 % environ à 80 % environ en poids de tensio-actifs choisis dans le groupe composé des tensio-actifs non ioniques, anioniques, cationiques, amphotères ou zwittérioniques, ou de mélanges de ces derniers; et de 0,1 % environ à 10 % environ en poids d'un mélange de polymères, d'oligomères ou de copolymères à base d'acides aminés répondant à la formule générale (I): dans laquelle le polymère, l'oligomère ou le copolymère contient au moins 5 % molaire environ d'un ou de plusieurs acides aminés et un acide organique. Lesdits polymères, oligomères ou copolymères à base d'acides aminés peuvent être obtenus par condensation d'un acide aminé basique, tel que la lysine, avec un acide organique. Les matériaux polymères, oligomères ou copolymères à base d'acides aminés sont utilisés comme agents d'apprêt des tissus, lesquels sont capables de conférer un aspect et une intégrité améliorés aux tissus et textiles lavés à l'aide de solutions de lavage contenant lesdits matériaux.
