Abstract: Immiscible components are controllably released into aqueous systems by impregnating silica-silicate open cell foams with the immiscible components. As the silica-silicate foams are gradually dissolved, the immiscible components are released. Fragrance oils and dyes are particularly adaptable for use in the invention. In fact, silica-silicate foams impregnated with fragrance oils having polar functional groups, exhibit an unexpectedly slower rate of dissolution into aqueous environments and consequently, fragrance oils and dyes admixed therewith are released in aqueous systems over extended time periods.

Abstract: A novel association complex in disclosed, formed by the interaction between a hexamethylenetetramine quaternary salt of a halogenated allyl halide and a water-soluble homopolymer of ethylene oxide. The composition is neutral in pH, fluoresces at a characteristic wavelength of 355 nanometers, has unusual moisture retention characteristics, and possesses the unique ability to inhibit viral replication. The composition is preferably used in aqueous solution, and finds utility as a protective moisturizing agent for the skin, as a healing agent for skin injuries, as a germicidal lubricant, and as a medication for topical application to lesions due to viral infections.

Abstract: Compositions of fragrance oils are stabilized with respect to potency and aesthetic quality toward the effects of heat and age by including in the formulations a quantity of alkylphenol ethers of polyethylene glycol, or more specifically, alkyl phenoxy polyethoxy ethanols wherein the polyether chain averages from 5 to 13 moles of ethylene oxide, and the alkyl portion of the molecule ranges from 6 to 20 carbon atoms. The alkyl portion of the molecule may be branched, unbranched, saturated or unsaturated. The oils are stabilized in respect to durability or intensity of odor with time and are rendered relatively insensitive to the deleterious effects of heating and/or aging in the presence of air. The presence of the stabilizers also eliminates the phenomenon of the "migration" of the perfume oil caused by repeated vaporization and condensation within an enclosed space.
