Abstract: A phosphate-free powdered dishwashing composition containing a mixture of a protease enzyme and an amylase enzymes have been found to be very useful in the cleaning of dishware. The compositions contain nonionic surfactants and a alkali metal silicate and bleaching agent.

Abstract: A high foaming light duty, liquid detergent with desirable cleansing properties and mildness to the human skin comprising a water soluble nonionic surfactant as the major active ingredient, a supplemental amount of a water soluble, foaming, alkyl ethoxylated ether sulfate anionic surfactant, an alkyl sulfate surfactant, and a water soluble, foaming zwitterionic betaine surfactant and the balance being water.

Abstract: Low viscosity and high pH disinfecting and bleaching all purpose cleaning compositions in microemulsion form, suitable in both concentrated and diluted forms for applying to surfaces to be cleaned and disinfected or sanitized, include hypochlorite, higher alcohol sulfate and higher paraffin sulfonate detergents, higher fatty acid soap, alkali metal hydroxide, liquid hydrocarbon, perfume, periodate, branched lower alcohol co-surfactant and water. The compositions are of improved lipophilic soil removing capability when diluted with water, are of about equivalent such capability in neat or concentrated form and are of significantly better hypochlorite stability on aging at room and elevated temperatures, compared to other microemulsion cleaners that contain hypochlorite. Their low viscosities facilitate spraying them from squeeze bottles or pump sprayers onto surfaces to be cleaned and disinfected or sanitized, such as floors and walls.

Abstract: An aqueous thixotropic automatic dishwasher composition comprising tripolyphosphate, a chlorine bleach compound, silicates, a thixotropic thickener and entrained air in an amount of 2% to 10% by volume.The composition preferably also contains a long chain fatty acid or its salt, an organic detergent active material, a foam depressant and an alkali metal carbonate. Also disclosed is a process for preparing aqueous thixotropic dishwasher detergent compositions having improved physical stability by entraining air into the composition in an amount such that the bulk and liquid phase specific gravities of the dishwasher detergent composition are approximately equal.

Abstract: A scented aqueous thixotropic dishwasher composition comprising tripolyphosphate, a chlorine bleach compound, a thixotropic thickener, a chlorine bleach stable fragrance and air in an amount of 2% to 10% by volume. The composition preferably also contains a long chain fatty acid or its salt, an organic detergent active material, a foam depressant and an alkali metal carbonate. Also disclosed is a process for preparing aqueous thixotropic dishwater detergent compositions having improved physical stability by entraining air into the composition in an amount such that the bulk and liquid phase specific gravities of the dishwasher detergent composition are approximately equal.

Abstract: The physical stability of liquid gel-like automatic dishwasher detergent compositions based on montmorillonite, attapulgite, hectorite or other inorganic colloid-forming clay or other thixotropic thickener is greatly improved by incorporating in the composition small amounts, such as 0.1 or 0.2 weight percent, of aluminum or zinc stearate or other polyvalent metal salt of long chain fatty acid. The aqueous compositions containing inorganic builder salts and other functional inorganic salts, chlorine bleach, bleach-stable detergent, thixotropic thickener and polyvalent metal salt of a fatty acid as a physical stabilizer remain stable against phase separation for periods in excess of six weeks under a wide range of temperatures. The thixotropic properties can be retained or improved using smaller levels of the clay thixotropic thickener than in the absence of the physical stabilizer.

Abstract: A security alarm device includes a housing of an electrically conductive material having a horizontal bottom base, a pair of upwardly extending end walls; a front face, and an upper end. An elongated rod member of an electrically conductive material having a threaded outer surface threadably engages a threaded hole in the bottom base and an opening in the top, wherein an end of an elongated bar member is affixed into a center transverse aperture of the rod member. An electric contact point within the housing communicates with bar member as it rotates within the housing causing the electric series circuit of the security alarm device to open and close. The series circuit of the security alarm device consists of a power source, an on/off switch, an alarm, the contact point, the housing, the rod member and the bar member. A mounting plate affixed onto the housing is adapted to be received by the door frame.
