The invention relates to antifogging agents for plastics which are obtainable by transesterification of native oils with PEG or mixtures of PEG and other polyols, to plastics containing these antifogging agents and to the use of mixtures obtainable by transesterification of native oils with PEG or mixtures of PEG and other polyols as antifogging agents in plastics.

Stabilizers containing ketofatty acid glycerides for Ca/Zn-stabilized

Partial esters of saturated, linear C.sub.22 -C.sub.34 -monocarboxylic acids with polyols containing at least 3 carbon atoms and at least 2 hydroxyl groups are provided. The partial esters contain on average at least 1 free hydroxyl group and are generally obtained as mixtures of partial esters of at least 2 of said C.sub.22 -C.sub.34 -monocaroxylic acids. Particularly contemplated are partial esters based on montanic acids. The partial esters exhibit excellent release effects and transparency properties when used as release agents for plastics based on PVC or PVC copolymers.
