The amount of essential oil blend you need will depend on the size of candle you are making. When making essential oil soy candles, usually 1-5% of the total volume or nett weight will be made up of your essential oil blend. So if you are making a 200g candle, 2-10g will be made up of your essential oil blend and 190-198g will be the wax. Expect some sweating on the surface of your candle when scenting with essential oils especially with particular waxes and in warmer weather. Sweating can sometimes be minimised by reducing the amount of essential oil you add and experimenting with pour temperatures or changing waxes, but it is very difficult to eliminate sweating 100% of the time.
