Abstract

Described are compositions comprising (a) 25 to 99% of organic phosphite or phosphonite, (b) 0.01 to 50% of organic amine, and (c) 0.01 to 25% of acid-binding metal salt, each based on the total weight of the composition, as well as a process for stabilising organic phosphites or phosphonites against hydrolysis by addition of organic amine and acid-binding metal salt. The described compositions are distinguished by their excellent stability to hydrolysis and have good storage stability even at high atmospheric humidity. The novel compositions and process products can be used with advantage as stabilisers for organic material against the harmful action of heat, oxygen and/or light.
