A stabilizer mixture for molding compounds based on polymers of vinyl chloride; use of said mixture; and molding compounds is disclosed. The heretofore known physiologically unobjectionable stabilizer systems have the disadvantage of disagreeable odor, as well as inadequate initial stability. In addition to physiologically unobjectionable stabilizers (e.g., metal soaps, salts of aromatic carboxylic acids, or metal phenolates), co-stabilizers of the present invention are used, in the form of derivatives of thiosalicylic acid esters masked at the mercapto group by monothioacetal formation. The field of application is hard and soft PVCs.
