Universal Additive (UA) is a versatile additive that is primarily used in candle making to help fragrance oil bind better to the wax. It also aids in the long-term retention of the scent, helps reduce mottling, and helps to reduce bubbles in the candle as it cools. As a bonus, it also adds a nice glossiness to candles. Usage 0.1 - 1% in container candles. Add at the beginning of the melt process. NOTE: By adding 10% of our specially formulated UA you can turn GW 416 into a wonderful tart and votive wax that pops straight out of the mould. Note: pour the GW 416 @ 82 degrees when adding 10% UA Wick experimentation necessary. Use sparingly as it changes the burn of the candle dramatically.
