摘要： 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.
