Abstract: Laundry detergents and their use for cold-water cleaning are disclosed. The detergents comprise a lipase and a mid-chain headgroup surfactant or an alkylene-bridged surfactant. The mid-chain headgroup surfactants have a C14-C30 alkyl chain and a polar group bonded to a central zone carbon of the C14-C30 alkyl chain. The alkylene-bridged surfactants comprise a C12-C18 alkyl chain, a polar group, and a C1-C2 alkylene group bonded to the polar group and a central zone carbon of the C12-C18 alkyl chain. Surprisingly, when combined with lipases, detergents formulated with the mid-chain headgroup or alkylene-bridged surfactants effectively liquefy greasy soils at low temperature and provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.

Abstract: Applicants have developed a physically and chemically stable solid composition containing a soil release polymer and an acidulant. The sour step thus accomplishes both stain removal and residual alkalinity removal. A novel method of using a soil release polymer and an acidulant together in the same post wash step of a laundry wash process is also disclosed. The solid composition is physically stable, even during aqueous dispensing, i.e. non-slumping and non-weeping. The solid could be formed through a melt, cast, or pressed process.

Abstract: We disclose a system for preparing antimicrobial surfaces, coated with metal oxide nanoparticles by means of a novel sonochemical method. These antibacterial surfaces are widely used in medical and other applications. The deposition of metal oxides known to possess antimicrobial activity, namely ZnO, MgO and CuO, can significantly extend the applications of textile fabrics, medical devices and other items and prolong the period of their use. By means of the novel sonochemical method disclosed here, uniform deposition of metal oxide nanoparticles is achieved simply.

Abstract: A container for a food and/or beverages is provided. The container is designed such that it may have the capability of absorbing excess thermal energy from the food or beverage, thereby cooling the consumable material to a desired temperature and maintaining the material at the desired temperature for a considerable period of time. The container typically includes an outer insulating shell; an inner heat conducting liner and a phase change material (PCM). To facilitate heat transfer to and from a food or beverage stored in the container, the PCM is commonly disposed between the outer insulating shell and the inner heat conducting liner and positioned in thermal contact with the inner heat conducting liner. The PCM may include a diol diester having a melting point of about 30 to 90° C.

Abstract: Repeatable and reliable chemical treatment for loose fibers is achieved by spraying or immersing loose fibers in a chemical treatment bath, and continuously moving the soaked fibers through a continuous centrifuge. The continuous centrifuge controls the wet pickup of the chemical formulation on the fibers and assures a substantially even chemical distribution on the centrifuged fibers. The centrifuged fibers may be dried to fix the chemicals in the chemical formulation to the fibers and/or to remove water from the chemical formulation. Recycling of the chemical formulation from the continuous centrifuge allows for the process to be performed more economically and in a more environmentally friendly fashion.

Abstract: The sublimation speed of dopant can be precisely controlled without being influenced by a change over time of intra-furnace thermal environment. A dopant supply unit equipped with an accommodation chamber and a supply tube is provided. A sublimable dopant is accommodated. Upon sublimation of the dopant within the accommodation chamber, the sublimed dopant is introduced into a melt. The dopant within the accommodation chamber of the dopant supply unit is heated. The amount of heating by means of heating means is controlled so as to sublime the dopant at a desired sublimation speed. The dopant is supplied to the melt so that the dopant concentration until the first half of a straight body portion of the silicon single crystal is in the state of low concentration or non-addition.
Abstract: A method for treating a sulfur-containing fabric and sulfur-containing fabrics with excellent antimicrobial properties are disclosed. First an aluminum salt is added to a sulfur-containing fabric. That product is then rinsed. The rinsed product is combined with an antimicrobial. In one embodiment, the sulfur-containing fabric is combined with an aqueous solution of an oxidizing agent prior to the addition of the aluminum salt. Fabrics treated by the method retain excellent antimicrobial activity even after repeated washings.
