  • Patent number: 6130252
    Abstract: A non-toxic, environmentally safe and easily employable insecticide and insect repellant is achieved by providing an aqueous composition incorporating ethanolamine based compounds, either independently or in combination with the ethanolamine based compounds being selected from both simple compounds and conjugated compounds. In one preferred embodiment, a highly effective composition is attained for safe, effective, direct topical application to humans and animals by employing between about 10% and 70% by volume of the entire composition of the ethanolamine-based compound. In alternate preferred embodiments, the insecticide is formulated for application to plants, trees, crops, and other vegetation to provide a composition which effectively controls bothersome insects, while being completely safe and non-injurious to the plant, tree, or crop, as well as to the flowers or fruit thereof.

  • Patent number: 5891914
    Abstract: Methods and compositions that provide for the long-term adhesion and slow-release of various bioactive agents on the surface of human skin utilize siloxane bridging agents activated for reaction with the skin surface which bind the bioactive agent to the skin surface. Since the topical agent remains bound to the continuously renewing epidermis, safety is enhanced for many bioactive agents. Slight modifications of the siloxane bridging compounds or bioactive agents allows for more or less adhesion to the skin, controlling the degree of release of the agent. Skin treatments according to the invention can provide enhanced repellency to microorganisms, insect bites, sun, water, poison ivy/oak, and other skin irritants, and other effects such as artificial skin coloring and administration of topical drugs, among others.

  • Patent number: 5756100
    Abstract: A repellent for agricultural crops that uses accepted all natural components to protect crops organically. The repellent uses a combination of red pepper, powdered, garlic and black pepper to repel undesirable pests. Hydrated calcium hydroxide is added to the combination to increase the stability of the resultant mixture. The calcium hydroxide also acts as a fertilizer on some soils by increasing soil pH. The peppers contain alkaloids that yield nitrogen when decomposed fully. The repellent comprises, by weight percentage, between 3% and 20% red pepper, between 3% and 20% powdered garlic, between 3% and 20% black pepper, and between 40% and 91% hydrated calcium hydroxide. Preferably, the repellent comprises 10.7% red pepper, 10.7% powdered garlic, 10.6 black pepper and 68% hydrated calcium hydroxide. The repellent components are combined and thoroughly blended to produce a mixture that may be applied to any crop to prevent most pest infestations.

  • Patent number: 5705175
    Abstract: Controlled release insect repellent or insecticide based on a non-aqueous gel composition comprising from about 1 to about 20 weight percent of one or more diblock, triblock, radial block and/or multiblock copolymers, or a mixture thereof, based on synthetic thermoplastic rubbers. The ratio of the diblock copolymer to triblock, radial block and/or multiblock copolymer can be varied from about 0 percent to about 100 percent in either direction. The higher the tri-block percentage, the stiffer the resultant gel. The material to be gelled is a hydrocarbon which based on its physical properties plays an important role in setting the controlled release rate. The composition of the hydrocarbon can vary in carbon chain length from an average of about C-13 to about C-30 and can vary in vapor pressure from about 2.3 mm Hg at 20.degree. C. to less than about 0.1 mm Hg at 20.degree. C. The hydrocarbon range on a weight basis is from about 65 to about 95 percent of the total weight of the gelled composition.
