    摘要: A process for making an alkyl and/or alkenyl oligoglycoside preparation having a magnesium salt concentration of less than about 10 ppm involving the steps of: (a) providing an alkyl and/or alkenyl oligoglycoside preparation having an active substance content of from about 10 to 70% by weight, based on the weight of the preparation; (b) providing an acid component; (c) adjusting the pH of the alkyl and/or alkenyl oligoglycoside preparation to from about 4 to 9.5 by combining the acid component with the alkyl and/or alkenyl oligoglycoside preparation to form a pH-modified alkyl and/or alkenyl oligoglycoside preparation; (d) providing a column charged with an ion exchange resin; and (e) purifying the pH-modified alkyl and/or alkenyl oligoglycoside preparation by passing it through the column of step (d) at a viscosity of from about 20 to 6,000 mPas, and at a temperature of from about 20 to 90° C. to form the alkyl and/or alkenyl oligoglycoside preparation having a magnesium salt concentration of less than about 10 ppm.
