  • Publication number: 20220363465
    Abstract: A dispenser for flowable materials includes a tube having a tube interior cavity, an open proximal end, and a distal end having a dispensing orifice. A dividing wall extends along the tube interior cavity and divides the tube into a plurality of chambers. A first flowable material is positioned in a first of the chambers. At least one additional flowable material is positioned in another of the chambers. Each of a plurality of pistons is seated in a proximal end of one of the chambers. A handle includes a plurality of pusher bars, with each pusher bar engaging one of the pistons. When one of the handle and the tube is received in the other of the handle and the tube, the handle and tube move coaxially with respect to one another, and the pistons force the flowable materials from each of the chambers out of the dispensing orifice.

  • Patent number: 5500153
    Abstract: The invention is directed to a handwashing laundry detergent composition containing a surfactant system including selected levels of an anionic surfactant and a nonionic surfactant mixture of polyhydroxy fatty acid amide surfactant and an amine oxide surfactant in a selected weight ratio. By judiciously selecting the surfactant system components and their respective levels and proportions as contained herein, the detergent composition surprisingly exhibits superior cleaning, sudsing and mildness during conventional hand washing operations. The inclusion of other adjunct detergent ingredients such as builders and other optional components enhance the unexpected superior cleaning, sudsing and mildness results achieved by the handwashing detergent product.

  • Patent number: 5486297
    Abstract: The present invention relates to a method for reducing dye fading of a fabric comprising depositing on the fabric a soil release agent capable of substantially absorbing ultraviolet and/or visible light (in the 200-700 nanometer wavelength range). The soil release agent is preferably deposited on the fabric during a laundering or drying operation. Preferably the weight ratio of soil release agent to fabric is between about 1:10,000 and about 1:100. The soil release agent has light-absorbing chemical structure groups which can include carbonyls, carboxylates, conjugated double bonds, and/or aromatic rings. Suitable soil release agents for use in the invention include oliogomeric, substantially linear, sulfonated poly-ethoxy/propoxy end-capped esters, which comprise oxyethyleneoxy units and terephthaloyl units.
