Abstract: Aqueous liquid detergent compositions containing a peracid and an effervesent system, wherein the effervescent system includes a first effervescent agent-containing component and a second acid agent-containing component, and the effervescent agent-containing component and the acid agent-containing component are chemically and/or physically separated from one another until effervescence is desired. Methods of laundering fabrics with such compositions.

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.

Abstract: Condensation products of basic amino acids with copolymerizable compounds which are obtainable by condensing(a) a basic amino acid selected from the group consisting of lysine, arginine, ornithine, tryptophane and mixtures thereof,(b) a copolymerizable compound selected from the group consisting of saturated monobasic carboxylic acids, unsaturated mono-basic carboxylic acids, polybasic carboxylic acids, carboxylic acid anhydrides, diketenes, monohydroxycarboxylic acids, polyhydroxycarboxylic acids and mixtures thereof, and optionally(c) at least one compound selected from the group consisting of amines, lactams, non-proteinogenic acids, alcohols, alkoxylated alcohols, alkoxylated amines, amino sugars, carbohydrates and sugar carboxylic acidsin a molar ratio of (a):(b) of from 100:1 to 1:1 at a temperature of at least 120.degree. C., and a process for the production of said condensation products by condensing compounds (a) and (b) and optionally (c) at a temperature of from 120.degree. to 300.degree. C.
