Abstract: The present invention relates to laundry detergent compositions which are suitable for use in inhibiting the re-deposition of fugitive dyes onto fabric during the course of the laundry process, said compositions comprising:a) 0.01% to 3% by weight, of a substantially water-insoluble polymeric dye transfer inhibiting agent, said agent consisting of a substantially water-insoluble cross linked polymer selected from the group consisting of polyamine N-oxide polymers; copolymers of N-vinylpyrrolidone and N-vinylimidazole; polyvinylpyrrolidones; polyvinyloxazolidones; polyvinylimidazoles; and mixtures thereof; wherein said agents have a particle size less than 50 microns;b) from 0.2% to 25% by weight of a surfactant system, said surfactant system comprising one or more detersive surfactants selected from the group consisting of anionic, nonionic, cationic, zwitterionic, ampholytic surfactants, and mixtures thereof; andc) the balance carriers and adjunct ingredients.

Abstract: The present invention relates to a method for applying a protective layer to vessels or utensils used in the food industry, such as the milk and meat industries, wherein the vessels or utensils are contacted with an aqueous (natural) soap solution and then rinsed with water. The soap solution used is 2-10 ml, preferable 2-5 ml liquid soap per 100 l water, e.g. mains water. Furthermore, the relevant method is advantageously carried out at a temperature of the range of 10.degree.-40 .degree. C. By using a soap layer as protective layer, the use of disinfectants has become superfluous in the food industry so that the attendant problem of discharging or rendering harmless harmful disinfectants foreign to nature has also been solved.
