Abstract: A method for producing glycolic acid includes selectively hydrogenating glyoxylic acid using a catalyst comprising at least one transition metal element, the glycolic acid produced, which has a bio-based carbon content of above 50%. A method for preparing a composition selected from the group consisting of cosmetics, home care products, personal care products, textiles, food, beverages, drugs, fragrances, inks, or paints includes adding the glycolic acid to the composition.

Abstract: The instant invention concerns the use of polymers obtained by radical copolymerization of a mixture of (1) acrylic acid; (2) methacrylic acid; and (3) at least one allylcatechol selected from 4-allylbenzene-1,2-diol, 3-allylbenzene-1,2-diol; methylated forms thereof (eugenols); and mixtures thereof, for treating a metallic surface intended to be adhesive-bonded to another surface, in order to impart a resistance to the adhesive failure to the resulting bonding.
