Abstract: Various liquid or low melting pesticide and herbicide formulations, previously formulated with organic solvents, are combined with a polymer in solution and co-precipitated to form a polymer complex which captures the pesticide or herbicide yet exists as a solid at ambient conditions. By preparing the pesticide or herbicide formulation as a solid complex, storage and handling of the formulation is possible without the potential for organic solvent emission. When the solid polymer complex is placed in water, a stable aqueous dispersion of the pesticide or herbicide is achieved as the polymer inhibits flocculation, with approximately 100% recovery of the pesticide or herbicide.

Abstract: A process is provided for making a free-flowing powder of a complex of an alpha-hydroxy acid (AHA) and/or a beta-hydroxy acid (BHA) and a vinylpyrrolidone (PVP) polymer, copolymer or graft polymers, as the complexing agent, at high acid loadings, preferably 20-60% by weight. The presence of VP polymers, copolymers or graft polymers in the complex reduces the skin irritation effect of the acid when applied to the skin of the user. The process involves applying an aqueous solution or slurry of the acid to PVP, and, substantially immediately thereafter, evaporating the water to form a free-flowing powder of the complex of the acid and VP polymers, copolymers or graft polymers.

Abstract: A three part cleaning composition uses C.sub.6 -C.sub.20 alkyl substituted lactam as a cleaning agent, an anionic surfactant and water to solubilize and remove oil or grease from hard surfaces. The lactam is provided in a ratio, relative to surfactant of 5-0.1 to 5-3.0, more preferably 5-0.1 to 5-1.0. The composition is surprisingly effective in forming micro-emulsions with the oil or grease and maintaining the emulsions for ease in disposal. Using an aqueous solution including C.sub.6 -C.sub.20 alkyl substituted lactam provides a low volatility, non-flammable degreasing solution, which is highly effective and biodegradable.

Abstract: A water based wetting agent uses higher alkyl substituted lactam, anionic surfactant and water to enhance the wetting properties of herbicide and pesticide formulations. The composition is effective in enhancing wetting times, and in some instances increases the formulation effectiveness through enhanced contact, better penetration and lower surface tension. Utilizing a herbicide or pesticide formulation including the wetting agent provides a fast absorption of actives with rapid uptake to promote weed control with no or minimal phytotoxicity at the use levels.
