  • Retard systems for the sustained release of medicinal and/or biological valuable materials from a depot carrier material
    Patent number: 5538738
    Abstract: The invention relates to the use of free radical-reactive cross-linker components based on olefinically unsaturated esters of lower hydroxycarboxylic acids and/or oligomers thereof for modifying depot materials, and especially retard systems, which contain medicinal and/or biological valuable materials in admixture with a carrier material in a sustained release form. The cross-linkers are present as polymer compounds in the application form of the retard system and may be provided in the retard system or depot material to be applied in a largely homogeneous as well as in a non-uniform distribution. The invention also relates to retard systems which contain medicinal and/or biological valuable materials and have been based on oligomer and/or polymer compounds of lower hydroxycarboxylic acids as carrier materials providing a sustained release of the active substance.

  • Antimicrobial mixtures
    Patent number: 5539001
    Abstract: Antimicrobial mixtures containing specific antimicrobial diols, e.g. 1,2-dodecanediol, and specific aromatic alcohols, e.g. phenylethyl alcohol or hydrocinnamic alcohol, are provided. Such mixtures with a weight ratio of diol to aromatic alcohol of 9:1 to 1:9 have been found to exhibit a synergistic effect, i.e. a high antimicrobial activity which cannot be explained by an additive effect of the very low-activity components. Such mixtures are useful in the disinfection of hard surfaces, in the production of disinfectant cleaning preparations and in the preservation of water-based preparations of microbially degradable substances.

  • Composition and process for treating metal
    Patent number: 5534082
    Abstract: Heating an aqueous mixture of a fluoroacid such as H.sub.2 TiF.sub.6 and an oxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long term stability against settling of any solid phase, even when the oxide, hydroxide, or carbonate phase before heating was a dispersed solid with sufficiently large particles to scatter light and make the mixture before heating cloudy. The clear mixture produced by heating can either be mixed with water soluble and/or water dispersible polymers, for example with dispersed polymers of the diglycidyl ether of bisphenol-A or an acrylic acid polymer, or with soluble hexavalent and/or trivalent chromium, to produce a composition that improves the corrosion resistance of metals treated with the composition, especially after subsequent painting.

  • Process for the purification of glycerol water
    Patent number: 5527974
    Abstract: The glycerol water (sweet water) accumulating in the high-pressure hydrolysis of natural fats and oils with steam into fatty acid and glycerol is continuously purified. Fats larger than 100 .mu.m in diameter are separated from the aqueous phase in a plate-type phase separator and are returned to the high-pressure hydrolysis process. The aqueous phase thus prepurified is passed through a cross-flow filtration membrane, more particularly a microfiltration membrane, and the concentrate is returned to the entrance of the plate-phase separator. Large product streams of glycerol water can be purified continuously, effectively and particularly economically despite frequent changes of provenance.
