Abstract:
A cleaning composition comprising approximately by weight:(a) 0.1% to 2% of a protein chemical linker selected from the group consisting of animal, vegetable and mixtures thereof;(b) 0.5% to 30% of at least one anionic surfactant having a carboxylate, sulfate or sulfonate group;(c) 3 to 15% of a second surfactant selected from the group consisting of amine oxide surfactants, zwitteriionic surfactants and alkylene carbonate surfactants; and(d) 50% to 99.8% of water, wherein excluded from the cleaning compositions are modified proteins which are defined as the product of a reaction in which the carboxylic or primary amino groups of a precursor protein have been modified to give at least one of the functional species: ##STR8## wherein R is an alkyl, alkenyl, aryl, cycloalkyl or heterocyclyl group containing not more than eight carbon atoms and up to two hetero atoms which may be the same or different and modified proteins which are made by modifications of protein precursor side chains comprising free carboxylic acid groups or free primary amino groups and protein aceous material whose primary amino or carboxylic acid side chain groups have been modified by reaction with C.sub.1 -C.sub.7 acyl- or alkyl-group-containing materials.
