  • Microemulsion detergent composition containing specific ethoxylated alcohol based surfactant system
    Patent number: 5597507
    Abstract: A detergent composition suitable for washing fabrics is in the form of a stable oil-in-water microemulsion and comprises an organic surfactant system, preferably wholly or predominantly consisting of ethoxylated nonionic surfactant having an average alkyl chain length of less than C.sub.12 and containing a high proportion of C.sub.10 material, a non-aqueous solvent, and optionally a water-soluble detergency builder, preferably polymeric. The composition can be used both for pre-wash treatment and as a main wash detergent.

  • Low-foaming, liquid cleaning compositions containing paraffin and fatty acid salt
    Patent number: 5391316
    Abstract: A liquid composition comprising a solubilized hydrophilic oil, a first surfactant which forms a calcium salt which is no more than sparingly soluble in an aqueous solution and a second surfactant which is foaming, different from the first surfactant and in weight excess over the first surfactant is described.

  • Process for making controlled sudsing detergent powder
    Patent number: 4363740
    Abstract: A process for manufacturing a low sudsing fabric washing powder in which a mixture of a suds-suppressant, such as an alkyl phosphoric acid ester or a salt thereof, and a hydrophobic material such as a petroleum jelly or a natural or synthetic wax is combined with a spray-dried detergent powder. The temperature of the powder at which combination takes place is lower than the drop-melting point of the mixture of suds-suppressant and hydrophobic material.

  • Alkyl phosphoric acid polyvalent salts-mineral oil lather controlled detergent compositions
    Patent number: 4362642
    Abstract: An insoluble polyvalent salt of a C.sub.12 -C.sub.24 mono- or di-alkyl phosphoric acid is used as a lather controller in detergent compositions. The use of this material as lather controller is especially beneficial in built fabric washing detergent compositions.
