Abstract: A method for making a suspension, dispersion or emulsion of non-agglomerated particles comprising forming particles in a liquid medium, wherein sonic energy is applied to the liquid medium at the point of contact of the reactants during the particle forming step to produce the suspension, dispersion or emulsion of non-agglomerated particles. The invention is also directed to a method for making a suspension of non-agglomerated pyrithione salt particles, comprising the steps of forming pyrithione salt particles in a liquid medium, wherein sonic energy is applied to the liquid medium during the forming step to produce the suspension of non-agglomerated pyrithione salt particles.

Abstract: The present invention relates to a composition being an aqueous dispersion of a polyurethane in water, said composition comprising water and the reaction product of (a) a water-dispersible isocyanate-terminated polyurethane prepolymer having an isocyanate content of between 1 and 15% by weight. The prepolymer comprises the following: an organic polyisocyanate adduct mixture having an average isocyanate functionality of between 2.0 and 4.0, and (b) an isocyanate reactive chain extender having a specified ratio of isocyanate reactive moiety to isocyanate index of the polyisocyanate adduct mixture. The polyisocyanate mixture must contain some dimer; however, other polyisocyanates, such as diisocyanates and polyisocyanate trimers, are advantageously added to the mixture. Also disclosed is a process for preparing this composition, and a method for coating a substrate with the composition.

Abstract: The present invention relates to a poly(oxyalkylated) alcohol composition represented by the formula:R.sub.1 O?CH.sub.2 CH(CH.sub.3)O!.sub.x (CH.sub.2 CH.sub.2 O).sub.y ?CH.sub.2 CH(OH)R.sub.2 !.sub.zwherein R.sub.1 is a linear, aliphatic hydrocarbon radical having from about 4 to about 18 carbon atoms including mixtures thereof; and R.sub.2 is a linear, aliphatic hydrocarbon radical having from about 2 to about 26 carbon atoms including mixtures thereof; x is an integer having a value from 1 to about 3; y is an integer having a value from 5 to about 30; and z is an integer having a value of from 1 to about 3. Also disclosed is an automatic dishwasher composition comprising the above-described epoxy-capped poly(oxyalkylated) alcohol and at least one component selected from the group consisting of detergent builder, bleach, anti-wear agent, and mixtures thereof.

Abstract: An analyzer and method for detecting and measuring the water content in a liquid sample in which the liquid sample is fed from its source to a head space chamber. The flow of liquid to the chamber is then halted, the water molecules in the liquid sample allowed to pass into the gaseous phase and escape from the liquid sample. A water-free carrier gas is caused to flow to the chamber and over the liquid to carry the gaseous water molecules to a moisture detector while the flow of the liquid sample to the head space chamber is halted.

Abstract: Disclosed herein is an antimicrobial composition characterized by synergistic antibacterial efficacy against Gram-negative bacteria and comprising an antimicrobially effective amount of a pyrithione salt or pyrithione acid, and an alcohol, preferably an aromatic alcohol. Also disclosed is a method of imparting antimicrobial activity to a composition comprising water or an organic solvent which comprises adding thereto an antimicrobially effective amount of the above-described antimicrobial composition.
