The vegan-friendly soy wax we use is from a sustainable source and is completely free of toxins, carcinogens, synthetics, palm oil, and any nasties. It is biodegradable and great for both your home and the earth, which means it's less likely to trigger allergies. We use lead-free (cotton) wicks for the same reason. Soy wax also melts slower than mineral/parafin wax (which is a crude-oil by product), which mean they typically last 30-50% longer than their mineral wax candle counterparts. Soy wax releases scent easier than paraffin candles to give a richer fragrance this means it will cover a much bigger area of your home with incredible scents.
