Title:
METHODS AND APPARATUSES FOR DELIVERING A VOLATILE COMPONENT VIA A CONTROLLED EXOTHERMIC REACTION
Document Type and Number:
WIPO Patent Application WO2002005620
Kind Code:
A3
Abstract:
Reaction mixtures that include exothermic generating particles having a water soluble coating encasing a portion of the particles, a volatile component and, optionally an aqueous solution, and a buffer. The reaction mixtures are especially suited to generate heat in a controlled manner. In one such controlled reaction, the reaction components are mixed together and the mixture increases in temperature to a Set Temperature within a predetermined time, and the mixture remains at the Set Temperature for a longer period of time. In this manner, volatile components can be controllably released to the surrounding environment. The volatile components can be, for example, a perfume, a fragrance, an insect repellent, a fumigant, a disinfectant, a bactericide, an insecticide, a pesticide, a germicide, an acaricide, a sterilizer, a deodorizer, a fogging agent and mixture of these. Apparatuses and methods that use these reaction mixtures are also disclosed.
