Abstract: Disclosed are granular detergent components and processes for making these components. The processes comprise the steps of: i) forming the granular detergent component by drying an aqueous solution, the aqueous solution comprising at least 50% of a cationic surfactant, to form a powder; and then ii) densifying the powder in the presence of a detergent powder selected from the group consisting of aluminosilicate, carbonate, bicarbonate, silicate, sulphate, citrate, clay and mixtures thereof and an acid selected from the group consisting of citric, sulphuric, hydrochloric, polycarboxylic acids and mixtures thereof. This granular detergent component consists essentially of the cationic surfactant, the acid and the particulate builder and the granular detergent component has a reserve acidity of at least 1.0 g HCl/100 g.

Abstract: A detergent composition is provided which contains a zeolite builder having a particle size, d.sub.50 of less than 1 micrometer; and a bicarbonate builder. The zeolite builder and bicarbonate builder are present in a ratio of from 5:1 to 1:1. Low levels of carbonate builder may be present such that the weight ratio of carbonate builder to the bicarbonate builder is less than 1:1.
Abstract: Detergent compositions comprise a surfactant selected from anionic, nonionic, cationic, amphoteric and zwitterionic detergent-active compounds and mixtures thereof; a detergency builder comprising zeolite P having a silicon to aluminium ratio not greater than 1.33; from 0.05% to 0.3%, by weight of the composition, anionic N-bonded stilbene optical brightener; and one or more additional components selected from manganese phthalocyaninetetrasulphonate and polymers selected from polyamine N-oxide polymers, copolymers of N-vinylpyrrolidone and N-vinylimidazole, polyvinylpyrrolidones, polyvinyloxazolidones, polyvinylimidazoles and mixtures thereof.

Abstract: An emulsified detergent composition is provided. The detergent composition comprises from about 0.1% to about 70%, by weight of the detergent composition, of a detersive surfactant wherein at least from about 70% to about 90%, by weight of the detersive surfactant, is a nonionic surfactant. The detergent composition also includes an electrolyte, in an amount sufficient to render the cloud point of the detergent composition to be less than about 20.degree. C., and water. The detersive surfactant and the water are in two phases in a weight ratio of about 1:10 to about 10:1 in the detergent composition. Superior cleaning and stain removal results because the emulsified detergent composition provides separation of the water and surfactant phases in a low water wash system over a broad temperature range and allows for cleaning below the cloud point of the surfactant system.
