Soy and scented candles from Plaid Parasol. Made with essential oils, vegetable soy wax, cotton-wicks and beautiful signature Perfume blends. Soy candles are candles made from soy wax, which is a processed form of soybean oil. They are usually container candles, because soy wax typically has a lower melting point than traditional waxes, but can also be made into pillar candles. Soy wax is a hydrogenated form of soybean oil. It is typically softer than paraffin wax and with a lower melting temperature, in most combinations.
