  • Process for manufacture of powdered detergent compositions containing fatty acid soaps
    Patent number: 4261850
    Abstract: A washing powder containing soap, normally in relatively large quantities, is made by combining a slurry containing washing powder components with a stream containing fatty acid or soap or a mixture of these. The fatty acid may be liquid or molten or in solution. The slurry is combined with the stream in such a way that the two are thoroughly admixed, for instance by feeding them to a pressurizing pump. When fatty acid is to be combined with the slurry, the latter will contain sufficient excess alkali to form soap in situ.

  • Non-aromatic hydrocarbon containing cleaning fluid
    Patent number: 4257909
    Abstract: The invention relates to a cleaning fluid essentially consisting of aliphatic or saturated liquid hydrocarbons and an ethoxylate. The cleaning fluid is a three-phase system consisting of a liquid hydrocarbon which is poor in aromatic content, a wetting agent such as alkyl aryl ethoxylate or alkyl ethoxylate as the second phase, and between the two phases, which are inter-indissoluble, a linking agent consisting of diesterfield monoglycerides of fatty saturated or unsaturated acids. The result is a well-wetting fluid which is poor in aromatic content and does not have an offensive odor but does have a good linking of the hydrocarbon by means of a linking agent which does not cause any inconvenience in the form of skin injuries, eczema or the like.

  • Denture cleansing tablet and process for making
    Patent number: 4256599
    Abstract: A two layered cleansing tablet for the self-acting cleansing of dentures. The layers of the tablet disintegrate at controlled rates so that denture cleansing action is made more efficient and effective compared to single layered tablet structures. The present tablet employs sulfonic acid in the tablet layer which disintegrates in a first stage cleansing step and further employs ethylene diamine tetraacetate in both tablet layers. Improved denture cleansing action is achieved even with no increase in the total amount of active agents employed in a tablet.
