Abstract: Improved reinforced devices, which can be retained in the vagina during intercourse, deliver spermicidal surfactants and provide contraceptive benefits. Lobed devices provide channels through which menses and other biological fluids can pass. Multi-compartment devices provide added protection against leakage, rupture or perforation during manufacture, handling and use.

Abstract: Zwitterionic surfactant compounds are made readily biodegradable in the environment by the inclusion of a biochemically and/or hydrolytically labile chemical linkage located between the cationic and anionic charge centers of the compounds and anywhere from the second to the tenth atom distant from the cationic charge center. The biodegradable linkage is preferably an ester or amide. The alkoxylated zwitterionic surfactants herein exhibit outstanding particulate soil removal performance and are also effective in removing oily soils from fabrics, in addition to being readily biodegradable. Also described are detergent compositions containing the zwitterionic surfactants, and, optionally containing cosurfactants and detergent builders.

Abstract: Peroxygen fabric bleaching compounds capable of yielding hydrogen peroxide in an aqueous solution are activated by long chain acyl compounds of the formula ##STR1## wherein Z is a leaving group which can be certain enols, carbon acids or N-alkyl quaternary imidazoles. The activated bleaching compositions herein are stable and especially suitable for use at relatively low temperatures. Bleaching processes and detergent compositions containing the bleaching compositions are also described.

Abstract: Dihydroxybenzoic acid derivatives and compositions containing same are useful for topical application to the skin as well as for systemic administration. The compounds are especially effective for providing an analgesic, anti-pyretic, and anti-inflammatory effect.

Abstract: Detergent compositions exhibiting superior detergency in cool or cold water fabric laundering operations comprise an amine oxide surfactant, an ethoxylated alcohol or ethoxylated alkyl phenol nonionic surfactant, and a C.sub.2 -C.sub.4 alkylene oxide condensation product having a molecular weight in the range of from about 2,000 to 40,000. The compositions preferably contain detergent builder materials, especially alkali metal silicates. Also described are cool or cold water laundering processes utilizing the compositions.

Abstract: A method of selectively controlling pyrophosphate-utilizing microorganisms comprises contacting said microorganisms with an organism controlling amount of certain organophosphonate compounds. Accordingly, a method of treating amoebiasis in a human or lower animal comprises administering to a human or lower animal in need of such treatment a safe and effective amount of such organophosphonate compound. Similarly, a method of selectively controlling Propionibacteria species in the manufacture of cheese comprises incorporating an organism controlling amount of an organophosphonate compound in the raw materials for said cheese.

Abstract: A process for preparing a substantially non-decaffeinated Robusta coffee having improved aroma and flavor by contacting the roasted coffee with a low molecular weight alcohol for from about 1 to about 20 minutes, and an improved roast and ground coffee and coffee blend made thereby.

Abstract: A composition and method for the preparation of a technetium-99 m based scintigraphic scanning agent are disclosed. The agent is prepared by the addition of a pertechnetate-99 m solution to an anhydrous salt composition comprising a phosphonic acid or a pharmaceutically acceptable salt thereof and a non-toxic, water-soluble, anhydrous, stannous, ferrous or chromous salt of hydrochloric or sulfuric acid.

Abstract: Dichloromethane diphosphonates affect the biosynthesis of collagen.

Abstract: Compositions for inhibiting the anomalous mobilization of calcium phosphates in animal tissue comprising an effective amount of certain phosphonate compounds as herein defined in combination with Vitamin D-like antirachitic compounds, and a method for treating or preventing conditions involving hard tissue demineralization in an animal comprising concurrently administering said phosphonates and Vitamine D-like antirachitic compounds to animals.

Abstract: A process for preparing a substantially non-decaffeinated Robusta coffee having improved aroma and flavor by contacting the roasted coffee with a non-chlorinated organic solvent system comprising a major portion of acetone and having a boiling point below about 200.degree. F. for from about 1 to about 20 minutes, and an improved roast and ground coffee and coffee blend made thereby.
