    摘要： Polyhydroxy amines reacted with fatty acid esters yield polyhydroxy fatty acid amide surfactants, such as the C.sub.11 -C.sub.17 fatty N-methyl glucamides, which may be contaminated with secondary amines. Such amines are acylated by a reaction with acetic anhydride. The resulting "clean" polyhydroxy fatty acid amide surfactants are preferred for use in the presence of oxidants, especially in the formulation of modern, colorless liquid detergents.

    摘要： 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 controllable 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 mixtures of these. Apparatuses and methods that use these reaction mixtures are also disclosed.
