Abstract:
A detergent composition comprising:a) 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; andb) from about 0.1% to about 10%, by weight of a mixture of amino acid based polymers, oligomers or copolymers of the general formula: ##STR13##wherein the polymer, oligomer, or copolymer contains at least about 5 mole %, of one or more basic amino acids, and wherein the polymer, oligomer, or copolymer is a condensate of lysine with at least one compound selected from the group consisting of aminocaproic acid, caprolactam, 2-ethylhexanoic acid, adipic acid, phthalic acid, terephthalic acid, oxalic acid, citric acid, C.sub.1 -C.sub.30 alkyldiketenes, C.sub.1 -C.sub.30 monocarboxylic acids that are linear or branched, saturated or unsaturated, and mixtures thereof;each R.sub.1 is independently selected from the group consisting of H, --C(O)--R.sub.4, C.sub.1 -C.sub.18 saturated or unsaturated, branched or linear alkyl, C.sub.2 -C.sub.18 saturated or unsaturated, branched or linear hydroxyalkyl, C.sub.3 -C.sub.8 cycloalkyl, C.sub.6 -C.sub.18 aryl, C.sub.7 -C.sub.18 alkylaryl, citric acid, ##STR14##each R.sub.2 is independently selected from the group consisting of H, NH.sub.2, ##STR15##each R.sub.3 is independently selected from the group consisting of OH, OM, ##STR16##each R.sub.4 is independently selected from the group consisting of C.sub.1 -C.sub.30 saturated or unsaturated, branched or linear alkyl, C.sub.3 -C.sub.8 cycloalkyl, C.sub.2 -C.sub.30 hydroxyalkyl, C.sub.6 -C.sub.18 aryl, C.sub.7 -C.sub.30 alkylaryl, and C.sub.2 -C.sub.100 linear or branched oxa or polyoxa-substituted alkyl;R.sub.5 may be absent, if R.sub.5 is present each R.sub.5 is independently selected from the group consisting of C.sub.1 -C.sub.12 linear or branched alkylene, cyclic alkylene, C.sub.2 -C.sub.12 linear oxa-substituted alkylene, C.sub.2 -C.sub.12 branched oxa-substituted alkylene, and C.sub.3 -C.sub.12 cyclic oxa-substituted alkylene;wherein:each x is independently from 0 to about 200;each y is independently from 0 to about 10;each z is independently 0 or 1; andM is selected from compatible cations; andprovided that:the sum of all x's is from 2 to about 200;any basic amine site on the polymer, oligomer, or copolymer may be optionally protonated, alkylated, or quaternized with constituents selected from the group consisting of H, CH.sub.3, alkyl, hydroxyalkyl, benzyl and mixtures thereof;any amine site may be optionally alkoxylated; andwhen two R.sub.1 groups are attached to a common nitrogen the two R.sub.1 s may form a cyclic structure selected from the group consisting of C.sub.5 -C.sub.8 alkylene, and C.sub.4 -C.sub.7 alkyleneoxyalkylene.
