Wax conditioner is used as a paraffin enhancer. It improves a candle's outer surface. Wax conditioner is also used as a stearine substitute, but is less aggressive. A,5% ratio is sufficient to make candles smoother, whiter and harder. When dipping, wax conditioner prevents the forming of bubbles and blisters. If moulding, it makes it easier to remove the candles from their casts.
