A mixture comprising A. at least one oligomeric compound comprising repeat units of the formula (I) in which the symbols are each defined as follows: R1 is hydrogen, C1- to C6-alkyl, formyl, C2- to C6-alkanoyl, C1- to C12-alkoxy, C5- to C6-cycloalkoxy, cyanomethyl, 2-hydroxyethyl, benzyl or a radical of the formula -CR'=CH-CO-OR' where R' is hydrogen, C1- to C6-alkyl or a radical of the formula -CO-OR', and R' is C1- to C18-alkyl, C5- to C8-cycloalkyl, C7- to C18-aralkyl, phenyl or tolyl; R2 is a mixture of C14- to C28-alkyl groups, where two of these alkyl groups, which must not differ by more than two carbon atoms, each make up at least 30% of this mixture; R3, R4 are each independently C1- to C6-alkyl; and B. at least one compound of the formula (II) or (III) where the symbols and indices are each defined as follows: n, m are each independently a natural number from 2 to 22 and R1, R3, R4 are each independently defined as specified in formula (I); is suitable as stabilizers for organic material. Estabilizadores apropiados para material orgánico son una mezcla que comprende A. cuando menos un compuesto oligomérico, que comprende unidades de repetición de la fórmula (I); (ver fórmula (I)), en la que los significados de los símbolos son como sigue: R1 es hidrógeno, alquilo de C1-C6, formilo, alcanoilo de C2-C6, alcoxi de C1-C12, cicloalcoxi de C5-C6, cianometilo, 2-hidroxietilo, bencilo o un radical de la fórmula -CR´=CH-CO-OR´´, en donde R´ es hidrógeno, alquilo de C1-C6 o un radical de la fórmula -CO-OR´´, y R´´ es alquilo de C1-C18, cicloalquilo de C5-C8, aralquilo de C7-C18, fenilo, o tolilo; R2 es una mezcla compuesta de grupos alquilo de C14-C28, en donde dos de estos grupos alquilo cuyo número de átomos de carbono no se permite que difiera por más de dos respectivamente, forman cuando menos 30% de la mezcla; R3 y R4, independientemente uno del otro, son alquilo de C1-C6; y B. cuando menos un compuesto de la fórmula (II) o (III) (ver fórmulas (II) y (III)) en donde los significados de los símbolos e índices son como sigue: n y m, independientemente uno del otro, son un número natural de 2 a 22, y R1, R3 y R4, independientemente uno del otro, tienen los significados proporcionados en la Fórmula (I).
