Best UV Inhibitors for Candles That Keep Their Color

Colour fade is a slow problem you notice too late, usually on a market stall in sunlight or a shop window. UV inhibitor slows that, and it also helps with the yellowing that vanilla heavy fragrance oils cause in white and pale wax. It is not a cure. It delays the change rather than stopping it, and results vary with dye type, wax, packaging, and how much direct light the candle actually sees. We weighed stated usage rates, how the additive dissolved and whether it clouded the wax, any reported effect on scent throw, and value at realistic dosing. Powder inhibitors suit makers colouring large batches and shipping to retail. Small quantities suit hobbyists testing a bright shade. Pair it with amber or opaque vessels and boxed storage, since keeping candles out of direct light does more than any additive on its own.
