1. A masterbatch concentrate comprising a stabilizer composition for polymeric organic materials, and at least one polymeric organic material identical to or compatible with a polymeric organic material to be stabilized by the masterbatch concentrate, wherein the stabilizer composition is present in an amount from 10 wt. % to 90 wt. %, based on the total weight of the masterbatch concentrate, said stabilizer composition consisting essentially of:
(i) a stabilizing amount of an ultraviolet light absorber (UVA) selected from the group consisting of: orthohydroxybenzophenone compounds; orthohydroxyphenyl benzotriazole compounds; and mixtures thereof;
(ii) a stabilizing amount of a co-active agent selected from the group consisting of C12-C60 monohydric alcohols; alkoxylated alcohols or monoalkyl ethers thereof; and mixtures thereof, wherein the co-active agent is present at from 1 wt. % to 99 wt. % based on the total weight of the stabilizer composition; and
(iii) a stabilizing amount of a hindered amine light stabilizer compound (HALS) comprising a functional group according to Formula (II):
