Abstract: A composition and method for insect repellent is provided. The composition in one form has on a weight percentage basis 2-4% ?-pinene; 2-4% borneol; 8-10% geraniol; 28-35% linalool; 25-38% linalyl acetate; 1-4% methyl salicylate; 2-4% myrcene; 2-4% para-cymene; 4-8% phellandrene; 1-4% thymol; and 2-4% vanillin. The composition has insect repellent properties.

Abstract: A compressed mixture of granular quatrepolymer compositions, quatrepolymer compositions and calcium hypochlorite and/or a hypochlorite-bromine additive for wastewater disinfection, or quatrepolymer compositions and a dechlorination agent and a wax binder selected from the group consisting of microcrystalline hydrocarbon wax and alkali metal salts of oxidized microcrystalline hydrocarbon wax. The mixture dissolves at a controlled rate, depending on the amount of wax binder used, in water thereby providing a source of available quatrepolymer compositions, quatrepolymer compositions and calcium hypochlorite or a hypochlorite—bromine additive for wastewater disinfection, or quatrepolymer compositions and a dechlorination agent over an extended period of time.

Abstract: The invention relates to colloidal particles of differing elemental compositions with differing morphologies, and to methods of preparing same. The invention also provides applications of such colloidal particles as labels in microscopy, as staining agents, and as biomolecule or drug carriers.
