Abstract:
A composition which comprises(a) candle wax which is white and unscented; white and scented; dyed and unscented; dyed and scented; dipped and unscented; or dipped and scented, and (b) an effective stabilizing amount of a combination of (i) a long chain hindered amine piperidine compound; and (ii) a UV absorber or an antioxidant, or a UV absorber and an antioxidant wherein the ratio by weight of (i) to (ii) is from 10:1 to 1:10 and wherein the long chain hindered amine piperidine compound is of formula 1, 2 or 3 â€ƒwhere G1, G2, G3, and G4 are independently alkyl of 1 to 8 carbon atoms, or G1 and G2 together are pentamethylene, or G3 and G4 together are pentamethylene; E5 is OE9 or â€”Oâ€”Eâ€”(OH)b; E9 is straight or branched chain alkyl of 1 to 24 carbon atoms, cycloalkyl of 5 to 12 carbon atoms, straight or branched chain alkenyl of 3 to 24 carbon atoms, cycloalkenyl of 5 to 12 carbon atoms, phenylalkyl of 7 to 15 carbon atoms, a radical of a saturated or unsaturated bicyclic or tricyclic hydrocarbon of 7 to 15 carbon atoms, aryl of 6 to 10 carbon atoms or said aryl substituted by one to three alkyl of 1 to 4 carbon atoms; or a group of formula IV E11 to E15 are independently hydrogen, halogen, nitro, cyano, alkyl of 1 to 18 carbon atoms, phenylalkyl of 7 to 15 carbon atoms, aryl of 6 to 10 carbon atoms, hydroxyl, carboxyl, alkylthio of 1 to 18 carbon atoms, alkoxy or 1 to 18 carbon atoms, phenylalkoxy of 7 to 15 carbon atoms, aryloxy of 6 to 10 carbon atoms, alkylcarbonyloxy of 2 to 18 carbon atoms, alkylsulfonyl of 1 to 18 carbon atoms, arylsulfonyl of 6 to 15 carbon atoms, sulfo or phosphono, or any two vicinal substituents connected together to form a mono- or polycyclic ring; E is a straight or branched chain alkylene of 1 to 18 carbon atoms, cycloalkylene of 5 to 18 carbon atoms, cycloalkenylene of 5 to 18 carbon atoms, a straight or branched chain alkylene of 1 to 4 carbon atoms substituted by phenyl or by phenyl substituted by one or two alkyl groups of 1 to 4 carbon atoms; b is 1, 2 or 3 with the proviso that b cannot exceed the number of carbon atoms in E, and when b is 2 or 3, each hydroxyl group is attached to a different carbon atom of E; R2 is T1, â€”COâ€”T1, â€”COâ€”Xâ€”T1, â€”(CH2)mâ€”COâ€”Xâ€”T1, â€”(CH2)pâ€”Xâ€”COâ€”T1, â€”COâ€”(CH2)mâ€”COâ€”Xâ€”T1, or â€”COâ€”(CH2)pâ€”Xâ€”COâ€”T1; m is 1 to 12; p is 1 to 12; T1 is straight or branched chain alkyl of 19 to 100 carbon atoms, or said alkyl substituted by one hydroxyl group and interrupted by one oxa moiety, or a mixture of such alkyl moieties; or T1 is â€”(Râ€”O)nâ€”Râ€”OG5 where R is ethylene, propylene, trimethylene, 1,2-butylene or tetramethylene, and n is 4 to 49 so that the total number of carbon atoms in T1 is at least 20; G5 is hydrogen, straight or branched chain alkyl of 1 to 24 carbon atoms, straight of branched chain alkenyl of 2 to 18 carbon atoms, cycloalkyl of 5 to 12 carbon atoms, phenylalkyl of 7 to 15 carbon atoms, phenyl, or said phenyl or said phenylalkyl substituted on the phenyl ring by 1 to 4 alkyl of 1 to 4 carbon atoms; X and X1 are independently â€”Oâ€”, or â€”Nâ€”(R4)â€”; R4 is hydrogen, alkyl of 1 to 18 carbon atoms or acyl of 2 to 6 carbon atoms; and R6 is T1, â€”Xâ€”T1, â€”(CH2)mâ€”COâ€”Xâ€”T1, â€”(CH2)pâ€”Xâ€”COâ€”T1, Xâ€”(CH2)mâ€”COâ€”X1â€”T1, or Xâ€”(CH2)pâ€”X1â€”COâ€”T1.
