Abstract

The present invention relates to a chemical composition comprising (a) a glycoside component A comprising at least one glycoside of the formula R(OG)x wherein R is an aliphatic hydrocarbon radical having 1 to 25 carbon atoms or is a radical of formula R1(OR2)m which does not have more than 25 carbon atoms and wherein n=0 to 24 and R1 and R2 are aliphatic hydrocarbon radicals; G is the residue of a saccharide moiety selected from the group consisting of fructose, glucose, mannose, galactose, talose, gulose, allose, altrose, idose, arabinose, xylose, lyxose, ribose and alkoxylated derivatives thereof; and x is 1 to 30; (b) an aspartate component B comprising at least one polymerisation product of aspartic acid, optionally in form of a copolymerisate with fatty acids, polybasic carboxylic acids, anhydrides of polybasic carboxylic acids, polybasic hydroxycarboxylic acids, monobasic polyhydroxycarboxylic acids, alkoxylated alcohols, alkoxylated amines, amino sugars, carbohydrates, sugar carboxylic acids and polymers thereof. The invention further relates to the use of such chemical compositions as corrosion inhibitor.
