1. Reaction products of N6,N6'-hexane-1,6-diylbis[N2,N4-dibutyl-N2,N4,N6-tris(2,2,6,6-tetramethylpiperidin-4-yl)-1,3,5-triazine-2,4,6-triamine] and allylbromide, subsequently reacted with ethaneperoxoic acid, hydrogenated

   WGK 1 (slightly hazardous to water)

2. Hexanedioic acid, polymer with 2-oxiranylmethyl neodecanoate (average molar weight 798 g/mol)

   WGK 2 (obviously hazardous to water)
