    Abstract: Powdered mixtures of chlorhexidine base with selected sugar acids or lactones from the group gluconic acid or gluconolactone, lactobionic acid (I), D-galactono-gamma-lactone (II), L-mannono-gamma-lactone (III), D-(-)-gulono-gamma-lactone (IV), D-(+)-galacturonic acid (V) and alpha-D-heptaglucono-gamma-lactone (VI). The formulations have extraordinary storage stability. New chlorhexidine salts with sugar acid anions based on (I) to (VI) and aqueous solutions of these are also described. The formulations, solutions and pure salts are used as disinfectants and to prepare disinfectants.

    Abstract: Acrolein copolymer prepared from acrolein and one or more polyhydric alcohols, in which the average molecular weight of the copolymer is 1000-10000 g/mol, the polyhydric alcohols are selected from 1,2-ethylene glycol, 1,2-propylene glycol, 1,4-butylene glycol, glycerol, cyclohexene glycol and/or polyethylene glycol, and the weight ratio of polyhydric acids to acrolein is 1:0.4 to 1:1, the process is characterized by release of monomeric acrolein in aqueous systems under pH>7 and hence a prolonged effect on microorganisms, in which

    Abstract: The potential hazards of acraldhyde make its direct handling for combatting microbial, vegetable and animal pests in the water and ground difficult. According to the invention, use is made of a composition releasing acraldhyde in contact with water at the point of use. The composition of the invention contains an acraldehyde acetal, preferably 2-vinyl-2, 3-dioxolane, and a compound hydrolysable to an acide with a pKs of lower than 4, especially one from the range of organic acid anhydrides, organic acid halides and inorganic halogen compounds forming hydrogen halides on hydrolysis.
