    摘要: Aqueous homogeneous preparations containing 0.0025 to 0.1% by weight antimicrobial biguanide compounds, 0.005 to 0.2% by weight of an alkyl glycoside, 0.01 to 0.3% by weight of a water-insoluble aromatic oil, 0.01 to 0.3% by weight of a solubilizer from the group consisting of ethoxylated fatty acid glycerides, ethoxylated fatty acid sorbitan partial esters or fatty acid partial esters of glycerol or sorbitan ethoxylates show high activity despite the low concentration of antimicrobial biguanide compounds. The clear solubility is obtained without ethanol or with only very small contents of up to 15% by weight of ethanol. The preparations are particularly suitable as mouthwashes.

    摘要: Alkyl and/or alkenyl oligoglycosides can be obtained in short reaction times and high yields by a process in which glycose is reacted with fatty alcohols at elevated temperature in the presence of sulfomonocarboxylic acids containing 2 to 8 carbon atoms, carboxylic anhydrides thereof and/or mixed cyclic sulfonic/carboxylic anhydrides thereof as acidic catalysts, the water of reaction is removed and the reaction products are worked up.
