ABSTRACT:
The final mixture in the manufacture of alkyl polyglycosides comprises an acidic, non-aqueous solution of alkyl polyglycosides in long chain alcohols. The invention relates to a novel method of neutralizing these solutions. First, a small part of the solution is withdrawn and a mixture comprised of an alcohol or alcohol mixture having 1-6 C atoms and water is added thereto, the withdrawn part is neutralized with an aqueous-, alcoholic-, or aqueous-alcoholic alkali. The amount of alkali necessary to neutralize the alkyl polyglycoside solution is calculated and added to the alkyl polyglycoside solution.
