Abstract: Detergent compositions comprising a surfactant system that is either (1) a mixture nonionic and zwitterionic detergent surfactants; (2) a mixture of nonionic and amphoteric (non-zwitterionic) detergent surfactants; or (3) short chain nonionic detergent surfactant, the nonionic detergent surfactants preferably being short chain and/or having peaked distribution; optional hydrophobic cleaning solvent; and polycarboxylate, especially dicarboxylate, detergent builder provide superior cleaning of all of the soils commonly found in the bathroom. The compositions have a pH of from about 1 to about 5.5, preferably from about 2 to about 4 when the dicarboxylate builder is used. The compositions are in the form of aqueous liquids. Short chain peaked distribution nonionic detergent surfactants provide surprisingly superior sudsing characteristics.

The compositions have a pH of from about 1 to about 5.5, preferably from about 2 to about 4 when the dicarboxylate builder is used.
Abstract: A pine oil cleaning concentrate composition comprising as essential constituents: pine oil, a nonionic surfactant with a cloud point of 20.degree. C. or less, a solubilizing agent and, water, feature reduced levels of volatile organic contents, including reduced amounts of pine oil, yet provides good blooming characteristics upon mixing of the concentrate composition with a further amount of water to produce a cleaning composition therefrom. The pine oil cleaning compositions may further include conventional additives, including germicidal agents, viscosity modification agents, fragrances (natural or synthetically produced), foaming agents, further surfactants, and coloring agents.
Abstract: Water-free detergent mixtures may be obtained by reacting secondary or tertiary amines with alkylating agents, in a per se known manner, in the presence of fatty alcohol polyglycol ethers with a HLB value in a range from 6 to 12, but without adding water or organic solvents. These products are suitable for preparing surface-active agents.
