An aerosol dispensing device including an aerosol valve in fluid communication with a reservoir. A nozzle is in fluid communication with the aerosol valve. The nozzle includes a nozzle insert with an exit orifice and a nozzle body to receive the nozzle insert. The nozzle body is in fluid communication with the aerosol valve. A primary swirl chamber is in fluid communication with one or more inlet ports. The exit orifice is disposed generally concentric with the primary swirl chamber and a secondary swirl chamber and is in fluid communication therewith. The inlet port(s) are in fluid communication with the aerosol valve and may enter the primary swirl chamber non-tangentially. The secondary swirl chamber has a first and second diameter. A ratio of the first diameter to the second diameter is greater than about 1 and less than about 1.6. The pest control composition is non-Newtonian.

Biocidal compositions including a carrier, a copper-containing material, and a copper-coordinating additive are provided. Methods of minimizing the color drift of a carrier are also provided. Methods of accelerating a color endpoint of a carrier are also provided.

A composition comprises thermally expanded microspheres suspended in a non-Newtonian fluid. The composition can be used for water-based applications, such as emulsion explosives, paint, water based coatings, coatings for thermal printing paper and other, porous ceramics, gypsum board, modelling clay, crack fillers, and cementitious compositions.
